In-Depth Explanation of Basenames
-
-
-

This in-depth explanation covers the use of basenames in the Intel® EPID scheme. It provides detail on name based signatures, random base signatures and how and when they are used.

-


-

-

-Random Base Signatures

-

By default, members sign using a random basename that is not shared with the verifier. This signing method is also referred to as signing using random base. Signing using random base provides the strongest privacy properties for the signer. If a member signs using random base, the signature generated by the member is anonymous.

-

When the signer and verifier agree to use random base, the basename is chosen at random for each signature. Two signatures using a random base cannot be linked to the same signer.

-

-Name Based Signatures

-

A name based signature is a type of signature that gives the verifier the ability to link Intel® EPID signatures from the same member, reducing the member's privacy. When using name based signatures, the signer and verifier agree on an explicit basename.

-

The verifier can ask the member to sign a message with a basename that the verifier chooses. If the member agrees to use a name based signature, then all the signatures created by the member using the same basename are linkable by the verifier, reducing the member's privacy.

-

Reasons why a verifier might require members to use a basename when signing include the following:

-
    -
  • Profiling for Advertising Widget-Mart wants to show targeted advertising to privacy-conscious customers. Widget-Mart requests that all customers use a specific basename so that Widget-Mart can build an individualized profile for each anonymous user, while Intel® EPID technology ensures that the retailer does not have the ability to aggregate that information with other retailers to build a more extensive profile of the consumer.
    • -
  • Voting A voting machine is designed so that each anonymous authorized voter can only vote once per race. A basename per office being contested allows the verifier to confirm that the voter has not already voted for that office, without revealing their identity or correlating their voting patterns across multiple races.
    • -
-
Warning
The use of a name-based signature creates a platform unique pseudonymous identifier. Because it reduces the member's privacy, the user should be notified when it is used and should have control over its use.

Building from Source
-
-
-

Table of Contents

- -
-

To use the SDK in a project, the code from the SDK must be included in that project. The easiest way to do this is to link to static libraries. The SDK comes with build scripts to build static libraries for common environments.

-

-Prerequisites

-

Building SDK code out of the box requires a number of tools. This section lists the tools used to build the SDK.

-

For more information on how to install these tools, refer to Guide to Installing Build Tools.

- - - - - - - - - - - -
Prerequisite Notes
A C/C++ compiler Core code in C. Unit tests need C++11 support.
Python Validated with v2.7.10
SCons Validated with v2.4.1
Parts 0.10.9.2 or later
-

-Building SDK with SCons

-

To use the SDK, you need to build it to generate libraries compatible with your build environment.

-

To build based on the default SConstruct file in the root directory of the SDK, invoke scons with no arguments. 

cd <path/to/sdk-root>
-scons
-

By default, this performs a 64 bit release build.

-

Potentially useful command line options:

- - - - - - - - - - - - - - - - - - - - - - - - - -
Option Action
--cfg=debug Build in debug mode
--cfg=release Build in release mode
--target=x86 Target x86
--target=x86_64 Target x86_64
--tc=cl Use MSVC to compile (Microsoft®* C/C++ Optimizing Compiler)
--tc=gcc Use GCC to compile (GNU* Compiler Collection)
--tc=icl,mstools Use Intel® C++ compiler
build:: Build the SDK (does not build unit tests)
utest:: Build unit tests
run_utest:: Run unit tests (builds tests if needed)
-c Clean the build
-

Built components appear in the _install directory of the SDK root.

-

-Alternate Makefile/Autoconf Based Build Approach

-

You can build with the make command on platforms that support Make/Autoconf.

-

In the root directory of the SDK, run: 

./configure
-make all
-make check
-make install
-

./configure sets up the default settings:

-
    -
  • The default compilers are GCC/G++. You can specify compilers via the CC and CXX variables. For example, ./configure CC=/opt/intel/bin/icc CXX=/opt/intel/bin/icpc
    • -
  • The default installation directory is ./_install. You can specify the installation directory by using ./configure --prefix=/usr/local/epid_install
    • -
  • To change OS bit version, use CFLAGS parameter -m32 and -m64. For example, ./configure CFLAGS=-m32
    • -
-

make check is optional. It builds and runs the unit tests.

-

Alternatively, you can use make build as a shortcut to replace make all, make check, and make install.

-

To clean the build, run make clean.

-

To remove the install directory, run make uninstall.

-

-Improving Performance with Commercial IPP

-

For higher performance, you can use the commercial version of Cryptography for Intel® Integrated Performance Primitives, available at https://software.intel.com/articles/download-ipp-cryptography-libraries.

-
Note
The SDK has been validated with v9.0.3 of the cryptography library.
-

To build the SDK using a commercial Intel® IPP installation, the IPPROOT environment variable must be properly configured to point to the IPP installation directory, as described in Setting Environment Variables* in the Intel® IPP User's Guide (PDF link).

-

Once the environment is configured, you can build using commercial IPP by specifying --use-commercial-ipp as a command line option.

-

-Example Programs

-

The SDK includes several examples that show you different aspects of how the Intel® EPID scheme works. In the SDK build, these examples are located in _install/epid-sdk/example.

- - - - - - - -
Name Description
signmsg Create Intel® EPID signature of message
verifysig Verify signature is from a group member in good standing
-

-Building with Other Build Systems

-

It is relatively straightforward to port the SDK to your build system of choice. The following dependency diagram shows the relationship between components and the sources used to build them.

If You Choose iKGF as Your Issuer
-
-
-

Table of Contents

- -
-

To use the Intel® EPID APIs, you need to use the following items that are created by the issuer:

-
    -
  • Group public key, which corresponds to the issuing private key kept by the issuer
    • -
  • Member private keys
    • -
  • Signature based revocation list (SigRL)
    • -
  • Private key based revocation list (PrivRL)
    • -
  • Group based revocation list (GroupRL)
    • -
-

If you want to use the Intel Key Generation Facility (iKGF) as the issuer, contact info@.nosp@m.digi.nosp@m.tal-c.nosp@m.p.co.nosp@m.m to get started.

-

If you choose to use iKGF as the issuer, you can take advantage of tools included in the SDK that are designed to make it easier for you to interact with iKGF by creating requests to update revocation lists and by extracting member private keys and group public keys from iKGF files.

Introduction to the Intel® EPID Scheme
-
-
-

Table of Contents

- -
-

Intel® EPID is a cryptographic protocol which enables the remote authentication of a trusted platform whilst preserving the user's privacy.

-

-Roles

-

In the Intel® EPID scheme, there are three roles: issuers, members, and verifiers.

-

The entities in these roles interact with each other in such a way that a member can prove to a verifier that it is a trusted member of a group without disclosing the identity of the member. Groups are created and managed by the issuer.

-
-epid_diagram_high_level_use_case.png -
-

-Issuers

-

The issuer is responsible for managing group membership. Issuer functionality is not included in the SDK.

-

The issuer manages groups by doing the following:

-
    -
  • Creates groups by generating one issuing private key and one group certificate for each group. The group certificate contains the group public key.
    • -
  • Creates group members by generating unique Intel® EPID member private keys through bulk provisioning. Member private keys are created from the issuing private key for the group.
    • -
  • Manages requests from prospective members to join existing groups by using the join protocol.
    • -
  • Creates and maintains signature based revocation lists and private key based revocation lists. These lists of members no longer in good standing allow members to be dropped from a group.
    • -
  • Creates and maintains group revocation lists.
    • -
  • Makes group public keys and revocation lists available to verifiers.
    • -
-
-epid_diagram_issuer_high_level.png -
-

-Members

-

The member is the entity that attempts to anonymously prove its group membership to the verifier.

-
    -
  • Members are authorized by the issuer as part of a group.
    • -
  • Each group member has a unique Intel® EPID private key, which corresponds to the group.
    • -
  • The member uses its member private key to sign a message to prove group membership to the verifier without revealing the identity of the member.
    • -
-
-epid_diagram_member_high_level.png -
-

-Verifiers

-

The verifier checks an Intel(R) EPID signature to establish whether it was signed by an entity or device that is a member in good standing.

-

The verifier acts on behalf of a party that needs to know it is communicating with a trusted device. Verifiers obtain group certificates and revocation lists from issuers and negotiate details of signature protocol with members.

-

A verifier can do the following:

-
    -
  • Confirm a member is in fact a member of a given group in good standing.
    • -
  • Obtain group certificates and revocation lists from issuers.
    • -
  • Negotiate details of signature protocol with members.
    • -
  • Manage a private list of revoked members, also called the verifier blacklist.
    • -
-
-epid_diagram_verifier_high_level.png -
-

-Groups

-

An Intel® EPID group represents a set of trusted entities called members. Issuers create groups and manage group membership. For each group, the issuer creates a group public key simultaneously with the corresponding issuing private key. The issuer uses the issuing private key to create unique member private keys for each group member, and makes the group public key available to verifiers.

-

All groups have the following:

-
    -
  • Group public key, which corresponds to the issuing private key kept by the issuer
    • -
  • Signature based revocation list
    • -
  • Private key based revocation list
    • -
  • Member private keys, generated from the issuing private key
    • -
-

If a signature based revocation list or private key based revocation list does not exist, it is assumed to be empty.

-

-Keys

-

The Intel® EPID scheme works with three types of keys: the group public key, the issuing private key, and the member private key. A group public key corresponds to the unique member private keys that are part of the group. Member private keys are generated from the issuing private key.

-

Additionally, in the Intel® EPID scheme, a private key can be revoked given a signature created by that key, even if the key itself is still unknown. Group membership can be revoked and entire groups can be revoked. For more information on revocation, refer to In-Depth Explanation of Revocation.

-

-Group Public Key

-

The group public key is the key used by the verifier to confirm that a member belongs to a group in good standing. Each member private key in a group is associated with the group's public key.

-

When a group is created, the group public key and the issuing private key are simultaneously generated by the issuer. The verifier obtains the group public key from the issuer.

-

-Issuing Private Key

-

The issuing private key is the key used by the issuer to generate unique private keys for each member of a given group. For every group public key, there is a corresponding issuing private key. The issuing private key remains with the issuer and is kept private.

-

-Member Private Key

-

The member private key is the key used by the member to digitally sign a message when attempting to prove to the verifier that the member belongs to the group and is in good standing.

-

Unique member private keys are generated by the issuer for each member of a given group. The same group public key corresponds to each member private key in the group.

-

-Member and Verifier Interaction

-

Each Intel® EPID member uses its Intel® EPID private key to digitally sign a message. The resulting signature is called an Intel® EPID signature.

-

The Intel® EPID verifier uses the group public key to verify the correctness of an Intel® EPID signature, i.e., to verify that the signature was indeed created by a member with a valid Intel® EPID private key.

-

However, the Intel® EPID signature does not convey any information about which unique private key was used to create the signature.

-CA public key

-

The CA (Certificate Authority) public key contains the ECDSA public key of the issuing CA. The verifier uses this key to authenticate that information provided by the issuer is genuine.

-

-DAA

-

Direct Anonymous Attestation (DAA) is a digital signature algorithm that supports anonymity by providing a group public verification key associated with many unique private signing keys. Intel® EPID enhances DAA by enabling a private key to be revoked given a signature created by that key, even if the key itself is still unknown.

-

-Elliptic curve

-

In elliptic curve cryptography, an elliptic curve is an algebraic structure used to create a function whose output is easy to compute, but whose input is difficult to compute given the output. Elliptic curve cryptography requires smaller keys compared to non-elliptic curve cryptography (based on Galois fields) to provide equivalent security.

-

-Elliptic curve point

-

An elliptic curve point is a point along an elliptic curve. The security of elliptic curve cryptography depends on the ability to compute a point multiplication and the inability to compute the multiplicand given the original and product points.

-

-Group

-

An Intel® EPID group represents a set of trusted entities called members.

-

Issuers create groups and manage group membership. For each group, the issuer creates a group public key simultaneously with the corresponding issuing private key. The issuer uses the issuing private key to create unique member private keys for each group member, and makes the group public key available to verifiers.

-

All groups have the following:

-
    -
  • Group public key, which corresponds to the issuing private key kept by the issuer
    • -
  • Signature based revocation list
    • -
  • Private key based revocation list
    • -
  • Member private keys, generated from the issuing private key
    • -
-

If a signature based revocation list or private key based revocation list does not exist, it is assumed to be empty.

-

-Group certificate

-

The group certificate contains the group public key. The group certificate is created by the issuer and obtained by the verifier. When the issuer creates groups, it generates one issuing private key and one group certificate for each group.

-

-Group public key

-

The group public key is the key used by the verifier to confirm that a member belongs to a group in good standing. Each member private key in a group is associated with the group's public key.

-

When a group is created, the group public key and the issuing private key are simultaneously generated by the issuer. The verifier obtains the group public key from the issuer.

-

-Intel® EPID

-

Enhanced Privacy ID (Intel® EPID) is a cryptographic protocol for attestation of a trusted platform while preserving the user's privacy. Intel® EPID can be used as a foundational building block for a multitude of security solutions.

-

-Intel® EPID signature

-

An Intel® EPID signature is a type of digital signature that preserves anonymity of the signer, while still proving the signer is a member of a trusted group.

-

-Issuer

-

The issuer is the entity in the Intel® EPID scheme that is responsible for managing group membership. Issuer APIs are not included in the SDK. An example of an issuer is the Intel Key Generation Facility. For sample issuer material, refer to Sample Issuer Material. For tools that can help you if you choose to use iKGF as your issuer, refer to If You Choose iKGF as Your Issuer.

-

The issuer manages groups by doing the following:

-
    -
  • Creates groups by generating one issuing private key and one group certificate for each group. The group certificate contains the group public key.
    • -
  • Creates group members by generating unique Intel® EPID member private keys through bulk provisioning. Member private keys are created from the issuing private key for the group.
    • -
  • Manages requests from prospective members to join existing groups by using the join protocol.
    • -
  • Creates and maintains signature based revocation lists and private key based revocation lists. These lists of members no longer in good standing allow members to be dropped from a group.
    • -
  • Creates and maintains group revocation lists.
    • -
  • Makes group public keys and revocation lists available to verifiers.
    • -
-

-Issuing private key

-

The issuing private key is the key used by the issuer to generate unique private keys for each member of a given group. For every group public key, there is a corresponding issuing private key. The issuing private key remains with the issuer and is kept private.

-

-Member

-

The member is the entity that attempts to prove its group membership to the verifier. Members are authorized by the issuer as part of a group and each group member has a unique Intel® EPID private key. The member uses its member private key to sign a message to prove group membership without revealing its identity. An example of a member is a PC with an embedded Intel® EPID member private key.

-

-Name-based signature

-

A name-based signature is a type of signature that gives the verifier the ability to link Intel® EPID signatures from the same member, reducing the member's privacy.

-

A name-based signature is created using the additional parameter of a basename. If a basename is not specified, a random number is chosen as the basename. If the member uses the same basename, the verifier can mathematically link signatures generated by the member, showing that the signatures are from the same member.

-

-Member private key

-

The member private key is the key used by the member to digitally sign a message when attempting to prove to the verifier that the member belongs to the group and is in good standing.

-

Unique member private keys are generated by the issuer for each member of a given group. The same group public key corresponds to each member private key in the group.

-

-Non-revoked proof

-

A non-revoked proof is part of an Intel® EPID signature that proves that the member is not a specific revoked entity in the signature based revocation list. The member provides the signature with a number of non-revoked proofs, one per revocation list entry, to prove to the verifier that the member does not correspond to any entry in the revocation list.

-

-Pairing

-

Pairing is a mathematical operation that maps two elliptic curve groups to a third multiplicative group.

-

-Revocation, revocation lists

-

Revocation lists are data structures used by the verifier to identify members that are no longer approved members of the group.

-

The verifier obtains the member private key based revocation list (PrivRL), signature based revocation list (SigRL), and group based revocation list (GroupRL) from the issuer. The verifier can also maintain its own verifier blacklist (VerifierRL). Verifier blacklist revocation only works with name based signatures.

-

-Verifier

-

The verifier is the entity that checks an Intel® EPID signature to establish whether it was signed by an entity or device that is a member in good standing.

-

The verifier acts on behalf of a party that needs to know it is communicating with a trusted device. Verifiers obtain group certificates and revocation lists from issuers and negotiate details of signature protocol with members.

Implementation Notes

Table of Contents

- -
-

-Random Number Generation

-

Some SDK APIs require a random number data source. A BitSupplier provides a source of random data. This function should be a cryptographically secure random number generator.

-
Warning
The pseudo-random number generator provided with the examples is for sample use only and is not suitable for cryptographically secure applications.
-

-Protecting Secrets

-

Member code works with private keys, so member code must be run in a trusted environment.

-
Warning
If member memory is available to an untrusted source, the member private key could be exposed.
-

The EpidZeroMemory function is used by the memory allocation routines EpidAlloc, EpidRealloc and EpidFree to wipe the memory as memory is freed.

-
Warning
The EpidZeroMemory function may be optimized away by some compilers. If it is, you should consider using a compiler or operating system specific memory sanitization function (e.g. memcpy_s or SecureZeroMemory).
-

-Replacing Math Primitives

-

SDK math primitives are designed to be replaced with your own implementation if you need to rely on custom hardware for performance. The SDK is designed to simplify this process by isolating implementation details behind a clearly defined interface, defined by the non-internal headers in the epid/common/math directory. Math functionality has detailed tests to ease validation.

-

-Octstring/Buffer Types

-

Serialized information in the SDK is passed in fixed size buffer types whenever possible. Collectively these fixed size buffer types are called Octstrings.

-

In epid/common/types.h, there are a large number of packed structs that contain other packed structs, which eventually contain OctStr* types. Normally these are named *Str and are refered to as Str types.

-

OctStr* types are buffers that hold N bits, where N is the number at the end of the type name. These types usually represent numbers in a Big Endian format (buffer[0] is the most significant value).

-

Str types generally represent fixed size groups of numbers such as a point or vector.

-

OctStr* and Str types are usually populated by reading a buffer from a file or other storage, or by calling a serialize function. OctStr* and Str types must be packed so that the compiler does not insert padding. In the current code, this is done using pragmas.

-
#pragma pack(1)
// OctStr* type holding 256 bits
typedef struct OctStr256 {
unsigned char data[256 / CHAR_BIT];
} OctStr256;
// Str type consisting of a single 256 bit number
typedef struct FqElemStr {
OctStr256 data;
} FqElemStr;
// Str type consisting of a two other Str types
typedef struct G1ElemStr {
FqElemStr x;
FqElemStr y;
} G1ElemStr;

Many APIs use void* parameters where OctStr* types are expected. If more than one size is allowed, a size parameter is usually also required.

-

-Flexible Arrays

-

A common idiom in the SDK is the use of flexible array types. These types are structs with the last element being an array of size 1 of some type. Flexible array types always have a size value embedded in the struct. The name of the count and array fields differs between flexible array types.

-
typedef struct Sample {
OctStr32 data;
OctStr32 count;
G1ElemStr array[1];
} Sample;

Flexible array types are expected to be in a buffer of size sizeof(FA) + ((N-1) * sizeof(E)) where FA is the flexible array type, N is the number of elements in the array and E is the type of each element. Note that this may be smaller than sizeof(FA) if N is 0, in which case referencing any element is an error.

-
Sample* AllocSample(size_t count) {
return (Sample*)malloc(sizeof(Sample)
+ (count * sizeof(G1ElemStr))
- sizeof(G1ElemStr));
}

In many cases, functions that accept flexible array types will also expect a buffer size that is compared against the computed size of the array as a sanity check.

Table of Contents

- -
-

The Intel® EPID SDK does not include issuer APIs. That means you cannot generate the following items for validation:

-
    -
  • Group public key, which corresponds to the issuing private key kept by the issuer
    • -
  • Member private keys
    • -
  • Signature based revocation list (SigRL)
    • -
  • Private key based revocation list (PrivRL)
    • -
  • Group based revocation list (GroupRL)
    • -
-

For validation purposes, you can use pre-generated sample data. This sample issuer material includes sample groups and revocation lists.

-

Sample compressed key material is not included in the package.

In-Depth Explanation of Revocation
-
-
-

This in-depth explanation covers the available options to revoke members in the Intel® EPID scheme. It also provides details on how and why each type of revocation is used.

-


-

-

-Revocation Hierarchy

-

The verifier only checks the revocation lists if the message was signed with a member private key that corresponds with the correct group public key.

-

After concluding that the signer is a member of a group, the verifier proceeds to check for group based revocation, then member private key based revocation, then signature based revocation, then verifier blacklist revocation.

-

If the group is revoked, the verifier stops and reports it.

-

If the member private key is revoked, the verifier does not check the signature based revocation list.

-

-Revocation List Versions

-

The verifier should periodically download the revocation lists (GroupRL, PrivRL, and SigRL) from the issuer and should use the latest revocation list during signature verification. The verifier should make sure that it gets the newest version of the revocation list during the update by checking RLver, the revocation list version number.

-

-Group Based Revocation

-

The group based revocation list, also called the GroupRL, has a list of revoked groups.

-

The issuer revokes the entire Intel® EPID group by revoking the group public key. This results in the revocation of all members of a group.

-

-Reasons the Issuer Might Revoke a Group

-

Group revocation is expected to be a rare event and would only happen under limited criteria.

-

Reasons to revoke a group might include:

-
    -
  • A manufacturing defect causes the devices in the group to malfunction.
    • -
  • A subscriber terminates or violates the service agreement.
    • -
  • The Intel® EPID issuing private key is exposed.
    • -
  • A critical vulnerability in a member implementation is identified.
    • -
  • Performance problems arise due to the expensive calculation of non-revoked proofs in signature based revocation, and a replacement group needs to be provisioned.
    • -
-

-Private Key Based Revocation

-

Private key based revocation is used to revoke a compromised member. For example, the issuer can revoke a member if the member private key is exposed. When a compromised member private key is identified, it needs to be communicated to the issuer so that the issuer can revoke the member private key.

-

The issuer manages and publishes the member private key revocation list, also called the PrivRL, which contains member private keys that can no longer be used.

-

-Reasons the Issuer Might Revoke a Member Private Key

-

Depending on the use case, these member private keys could belong to members whose identity was compromised. For example, if a member private key is exposed online, allowing group members to be impersonated, then the compromised member private key is known, and the issuer revokes the member private key.

-

-Signature Based Revocation

-

In signature based revocation, the issuer revokes a member based on the signature generated by the member. This revocation method is used when a member becomes subject to revocation criteria, but the issuer does not know the member's member private key.

-

The issuer manages and publishes the signature based revocation list, also called SigRL.

-

Entries in the SigRL cause signing to take longer for all members of the group. Therefore, when an issuer receives a signature revocation request, it first checks the signature against all entries in the private key based revocation list. If the signature was generated by a revoked private key, then it is not placed in the SigRL.

-

For the same reason, if the issuer were requested to revoke a private key, and the current SigRL had entries that corresponded to that private key, then the issuer would remove those entries from the SigRL.

-

-Signing with Non-Revoked Proofs

-

The verifier and the member both use the SigRL managed by the issuer (the method of obtaining the SigRL is outside the scope of the SDK). The member sends the verifier an Intel® EPID signature that includes a number of non-revoked proofs that correspond to each revoked member in the SigRL.

-

In other words, the member mathematically proves that it is not any of the members who created the entries on the SigRL. One proof of non-revocation is generated by the member per entry in the SigRL. A single proof indicates the member in question cannot be the one who generated that signature in the SigRL.

-

For privacy, Intel® EPID signatures that are generated by the same member are unlinkable by default. This means that the verifier cannot recognize if two Intel® EPID signatures are from the same device. Therefore, multiple Intel® EPID signatures on the SigRL could be from the same member.

-

-Reasons the Issuer Might Revoke an Intel® EPID Signature

-

Reasons for revoking a signature might include the following:

-
    -
  • A member's signature is connected to an aspect of its behavior that indicates that the member is compromised.
    • -
  • A member repeatedly generates a constant signature for the same message. Per the Intel® EPID algorithm, multiple signatures generated for the same challenge must be different.
    • -
-

-Verifier Blacklist Revocation

-

Verifier blacklist revocation is similar to signature based revocation in that it can be used to revoke a member using only a signature from a compromised member. Unlike the procedure for the signature based revocation list, members do not have to create non-revoked proofs for each entry on the verifier blacklist. Instead, the verifier relies on the member to use a basename when creating the signature (in other words, to use a name based signature) in order to determine if the same member created any of the signatures on the verifier blacklist.

-

For the verifier to determine that a member created an entry on the verifier blacklist, the member and verifier must use the same basename. The mechanism that allows them to agree on a basename is outside the scope of the SDK.

-

For more information on basenames, refer to Name Based Signatures.

-

The verifier adds a signature to a blacklist when the verifier does not want to trust the signer, but the verifier does not have enough reason to send a request to the issuer to revoke the member's signature.

-

When the verifier tracks a member using a basename, and decides the member is not trustworthy, the verifier can add the member's signature to the verifier blacklist.

-

-Reasons the Verifier Might Revoke an Intel® EPID Signature

-

Reasons a verifier might revoke a member based on its tracked signatures include the following:

-
    -
  • A service provider receives a complaint about a customer. In this case, even though the verifier no longer trusts that customer to use the service, the verifier does not have a case to petition the issuer to revoke the member.
    • -
  • A service provider detects suspicious behavior that might indicate illegal activity or another violation of the service provider's policy.

-SDK Components

-

The SDK is divided into logical components to separate responsibilities and create interfaces that you can re-implement using custom tools such as hardware accelerators.

-
-sdk_block_diagram.png -
-


- The Intel® EPID SDK is divided into the following components:

-

Components in the SDK Core implement the features of Intel® EPID.

- - - - - - - - - - - - - -
Component Description
member Library containing APIs needed to implement a member
verifier Library containing APIs needed to implement a verifier
common Library containing common types and functions
math Math primitives used by member and verifier
IPP A C-only non-optimized subset of Intel® IPP
-

Examples show how to use the SDK APIs in working code.

- - - - - - - - - - - -
Component Description
signmsg A sample program showing how to sign messages
verfifysig A sample program showing how to verify signatures
util Common utilities used by samples
Sample Issuer Material Sample keys and revocation lists
-

Tools implement utility code to interact with Intel® EPID related services such as the Intel® Key GenerationFacility (iKGF)".

- - - - - - - - - - - - - -
Component Description
extractgrps A tool to extract groups from a bulk group file
extractkeys A tool to extract member keys from a bulk key file
revokegrp A tool to create a revocation request for a group
revokekey A tool to create a revocation request for a member key

-

The SDK comes with a number of other components that support building and validating the code.

- - - - - - - -
Component Description
gtest gtest unit test framework
Build Scripts Scripts to configure and build the SDK
-

Math primitives are implemented in the math sub-component of common. The reference math primitive implementation is based on a non-optimized Vanilla C subset of the Intel® Performance Primitives. Math is designed so that you can replace its implementation to call custom hardware IP blocks or optimized libraries.

-

Intel® EPID 1.1 Compatibility

-

In addition to the default Intel® EPID 2.0 APIs, the verifier component also includes APIs that allow verification of Intel® EPID 1.1 signatures.

-

Billions of existing devices, including most Intel platforms manufactured since 2008, create signatures that need Intel® EPID 1.1 verification.

-

For details on verifying Intel® EPID 1.1 signatures see EPID 1.1 support in the API Reference.

-

-Filesystem Layout

-

The Intel® EPID SDK has two filesystem layouts: the Source Layout and the Install Layout.

-

The Source Layout is what you find when you download the SDK and extract it to disk. This layout contains all of the files that you need to build the libraries, samples, tests, and data generated by the SDK.

-

The Install Layout is the layout of files under the _install folder after you build the SDK.

-

-Source Layout

-

The Source Layout is used by the build scripts in the Intel® EPID SDK to find components and files needed to create libraries and executables.

Signing and Verification Tutorial
-
-
-

Table of Contents

- -
-

The Intel® EPID SDK provides example tools to show you how to use the Intel® EPID SDK APIs. These examples are called signmsg and verifysig.

-

You can build these examples using the instructions in Building from Source. The tutorial assumes _install/epid-sdk/example is the current directory.

-

All command lines in this tutorial use posix command line conventions; for other systems, adjust accordingly.

-

For the code used in this tutorial, refer to Walkthroughs of Examples Showing API Usage.

-
Note
The data for running this tutorial is pre-generated. Once the samples are built, the data is in the _install/epid-sdk/example/data directory. See Sample Issuer Material.
-

-Creating an Intel® EPID Signature of a Given Message

-

The example application signmsg shows you how to create an Intel® EPID signature of a given message. 

$ ./signmsg -h
-Usage: signmsg [OPTION]...
-Create Intel(R) EPID signature of message
-
-Options:
-  --sig=FILE
-      write signature to FILE (default: sig.dat)
-
-  --msg=MESSAGE
-      MESSAGE to sign
-
-  --bsn=BASENAME
-      BASENAME to sign with (default: random)
-
-  --sigrl=FILE
-      load signature based revocation list from FILE
-
-  --gpubkey=FILE
-      load group public key from FILE (default: pubkey.bin)
-
-  --mprivkey=FILE
-      load member private key from FILE (default: mprivkey.dat)
-
-  --mprecmpi=FILE
-      load pre-computed member data from FILE
-
-  --mprecmpo=FILE
-      write pre-computed member data to FILE
-
-  --capubkey=FILE
-      load IoT Issuing CA public key from FILE (default: cacert.bin)
-
-  --hashalg={SHA-256 | SHA-384 | SHA-512}
-      use specified hash algorithm (default: SHA-512)
-
-  -h, --help
-      display this help and exit
-
-  -v, --verbose
-      print status messages to stdout
-

To sign a message, a group member in good standing uses the following command: 

$ ./signmsg --msg="test0"
-

The above command signs a message "test0". signmsg uses default options for the group public key, member private key, hash algorithm and IoT Issuing CA public key. All other parameters that are not given are ignored. The command produces a signature file: sig.dat

-

-Verifying an Intel® EPID Signature

-

The example application verifysig shows you how to verify that a given Intel® EPID signature is produced by a member in good standing. 

$ ./verifysig -h
-Usage: verifysig [OPTION]...
-Verify signature was created by group member in good standing
-
-Options:
-  --sig=FILE
-      load signature from FILE (default: sig.dat)
-
-  --msg=MESSAGE
-      MESSAGE that was signed (default: empty)
-
-  --bsn=BASENAME
-      BASENAME used in signature (default: random)
-
-  --privrl=FILE
-      load private key revocation list from FILE
-
-  --sigrl=FILE
-      load signature based revocation list from FILE
-
-  --grprl=FILE
-      load group revocation list from FILE
-       (default: grprl.bin)
-
-  --verifierrl=FILE
-      load verifier revocation list from FILE
-
-  --gpubkey=FILE
-      load group public key from FILE (default: pubkey.bin)
-
-  --vprecmpi=FILE
-      load pre-computed verifier data from FILE
-
-  --vprecmpo=FILE
-      write pre-computed verifier data to FILE
-
-  --capubkey=FILE
-      load IoT Issuing CA public key from FILE
-   (default: cacert.bin)
-
-  --hashalg={SHA-256 | SHA-384 | SHA-512}
-      use specified hash algorithm for 2.0 groups (default: SHA-512)
-
-  -h, --help
-  display this help and exit
-
-  -v, --verbose
-      print status messages to stdout
-

To verify that a signature is from a member in good standing, the verifier uses the following command: 

$ ./verifysig --msg="test0"
-signature verified successfully
-

This verifies that the default signature file sig.dat is generated for the message "test0" by a member in good standing. verifysig uses default inputs for group public key, hash algorithm and IoT Issuing CA public key. All other parameters are ignored. The output verifysig: signature verified successfully denotes that the verification is successful.

-

-Linking Intel® EPID Signatures from the Same Member

-

A name based signature is created using the additional parameter of a basename. If the member uses the same basename, the verifier can mathematically link signatures generated by the member, showing that the signatures are from the same member.

-

To validate a signature with a basename, you need to use the same basename for signing and verification. The mechanism for ensuring that the member and verifier use the same basename is outside the scope of the SDK.

-

If a basename is not provided, then the member uses a random basename and the signature generated by the member is anonymous.

-

For more general information on why you might want to use a basename, refer to Name Based Signatures.

-
Warning
The use of a name-based signature creates a platform unique pseudonymous identifier. Because it reduces the member's privacy, the user should be notified when it is used and should have control over its use.
-

To sign message "test0" with a basename "base0": 

$ ./signmsg --msg="test0" --bsn="base0"
-

To verify the signature: 

$ ./verifysig --msg="test0" --bsn="base0"
-verifysig: signature verified successfully
-

To validate a signature, you need to use the same message for signing and verification. The mechanism for ensuring that the member and verifier use the same message is outside the scope of the SDK.

-

Member and verifier must also use the same hash algorithm and basename, if applicable.

-

-Expected Failures

-

The signature verification process fails if there is a parameter mismatch between sign and verify operations. Here are some examples.

-

Verification fails if there is a mismatch in the message: 

$ ./signmsg --msg="test0"
-$ ./verifysig --msg="test1"
-verifysig: signature verification failed: invalid signature
-

Verification fails if there is a mismatch in the basename: 

$ ./signmsg --msg="test0" --bsn="base0"
-$ ./verifysig --msg="test0" --bsn="base1"
-verifysig: signature verification failed: invalid signature
-

The Intel® EPID SDK supports the following hash algorithms: SHA-256, SHA-384, SHA-512. The selected hash algorithm must be the same for both sign and verify. Mismatch in hash algorithm results in verification failure: 

$ ./signmsg --msg="test0" --hashalg=SHA-256
-$ ./verifysig --msg="test0" --hashalg=SHA-384
-verifysig: signature verification failed: invalid signature
-

-Revocation

-

Revocation lists are data structures used by the verifier to identify members that are no longer approved members of the group.

-

The verifier obtains the member private key based revocation list (PrivRL), signature based revocation list (SigRL), and group based revocation list (GroupRL) from the issuer. The verifier can also maintain its own verifier blacklist (VerifierRL).

-

-Detecting Revoked Group from Group Revocation List

-

Verification of a signature fails if it is generated by a member of a group that is revoked in the group revocation list.

-

For example, 

$ ./signmsg --msg="test0" --gpubkey=data/groupb/pubkey.bin --mprivkey=data/groupb/member0/mprivkey.dat
-$ ./verifysig --msg="test0" --grprl=data/grprl.bin --gpubkey=data/groupb/pubkey.bin
-verifysig: signature verification failed: signature revoked in GroupRl
-

The verification fails because groupb is revoked and is an entry in the group revocation list (grprl.bin).

-

-Detecting Revoked Member from Private Key Based Revocation List

-

Verification of a signature fails if it is generated by a member whose private key is revoked in a private-key based revocation list.

-

For example, 

$ ./signmsg --msg=test0 --gpubkey=data/groupa/pubkey.bin --mprivkey=data/groupa/privrevokedmember0/mprivkey.dat
-$ ./verifysig --msg=test0 --privrl=data/groupa/privrl.bin --gpubkey=data/groupa/pubkey.bin
-verifysig: signature verification failed: signature revoked in PrivRl
-

The verification fails because the private key of privrevokedmember0 is revoked and is an entry in the private key based revocation list of groupa (privrl.bin).

-

-Detecting Revoked Member from Signature Based Revocation List

-

Verification of a signature fails if it is generated by a member whose signature is revoked in a signature based revocation list. 

$ ./signmsg --msg="test1" --sigrl=data/groupa/sigrl.bin --gpubkey=data/groupa/pubkey.bin --mprivkey=data/groupa/sigrevokedmember0/mprivkey.dat
-signmsg: signature revoked in SigRL
-$ ./verifysig --msg="test1" --sigrl=data/groupa/sigrl.bin --gpubkey=data/groupa/pubkey.bin
-verifysig: signature verification failed: signature revoked in SigRl
-

The message "test1" is signed by signmsg with a warning signmsg: signature revoked in SigRL. This means that the signature of sigrevokedmember0 is revoked in the signature based revocation list. The verification fails because the signature was generated by sigrevokedmember0, which is revoked and is an entry in the signature based revocation list of groupa (sigrl.bin).

Generating an Intel® EPID Signature
-
-
-

This walkthrough of the signmsg example shows you how to use SDK APIs to generate an Intel® EPID signature. Signmsg is built during the SDK build.

-


-

-

First, we include headers so we have access to needed declarations.

-

#include <stdlib.h>
#include <string.h>
#include "src/signmsg.h"
#include "src/prng.h"
#include "util/envutil.h"
#include "util/stdtypes.h"
#include "util/buffutil.h"
#include "epid/member/api.h"
#include "epid/common/file_parser.h"

-

The prng.h header provides access to a pseudo-random number generator needed for signing, while the utility headers are used by signmsg for logging and buffer management. The epid/member/api.h header provides access to the core member APIs. The epid/common/file_parser.h header provides an API for parsing buffers formatted according to the various IoT Intel® EPID binary file formats.

-


-

-

We define a stub function responsible for checking that the CA certificate is authorized by the root CA.

-

bool IsCaCertAuthorizedByRootCa(void const* data, size_t size) {
(void)data;
(void)size;
return true;
}

-

IsCaCertAuthorizedByRootCa is called from main.c to validate the CA certificate before calling SignMsg. In an actual implementation, you need to provide an implementation to validate the issuing CA certificate with the CA root certificate before using it in parse functions.

-


-

-

The core signing functionality is contained in SignMsg.

-

EpidStatus SignMsg(void const* msg, size_t msg_len, void const* basename,
size_t basename_len, unsigned char const* signed_sig_rl,
size_t signed_sig_rl_size,
unsigned char const* signed_pubkey,
size_t signed_pubkey_size, unsigned char const* priv_key_ptr,
size_t privkey_size, HashAlg hash_alg,
MemberPrecomp* member_precomp, bool member_precomp_is_input,
EpidSignature** sig, size_t* sig_len,
EpidCaCertificate const* cacert) {

-

The SignMsg parameters are either received by the member, or they are part of the member's configuration. The exceptions are the sig and sig_len parameters, which are used to output the signature.

-

The verifier might send the message to the member or there may be another mechanism to choose the message, but the way the message is communicated is outside the scope of the Intel® EPID scheme.

-

We use the parameters member_precomp and member_precomp_is_input to pass in a pre-computation blob if provided. We can use the pre-computation blob to increase performance when verifying signatures repeatedly with the same group public key.

-

The member knows the group public key and the member private key.

-

The member and the verifier agree on the message, basename, hash algorithm, and SigRL that the member uses for signing.

-


-

-

Next we do basic variable setup and argument checking.

-

EpidStatus sts = kEpidErr;
void* prng = NULL;
MemberCtx* member = NULL;
SigRl* sig_rl = NULL;
do {
GroupPubKey pub_key = {0};
PrivKey priv_key = {0};
size_t sig_rl_size = 0;
if (!sig) {
sts = kEpidBadArgErr;
break;
}

-

We create pointers to resources to be allocated and use the do {} while(0) idiom so that we can reliably free resources on return from SignMsg.

-

We create variables on the stack to hold the group public key and member private key.

-

Finally we check to make sure that sig is a vaild pointer.

-


-

-

Next, we authenticate and extract the group public key using EpidParseGroupPubKeyFile.

-

sts = EpidParseGroupPubKeyFile(signed_pubkey, signed_pubkey_size, cacert,
&pub_key);
if (kEpidNoErr != sts) {
break;
}

-

EpidParseGroupPubKeyFile takes a buffer containing a group public key in issuer binary format and validates that the public key is signed by the private key that corresponds to the provided CA certificate, extracting the key in the process.

-


-

-

We authenticate and extract the signed SigRL using EpidParseSigRlFile.

-

if (signed_sig_rl) {
// authenticate and determine space needed for SigRl
sts = EpidParseSigRlFile(signed_sig_rl, signed_sig_rl_size, cacert, NULL,
&sig_rl_size);
if (kEpidSigInvalid == sts) {
// authentication failure
break;
}
if (kEpidNoErr != sts) {
break;
}
sig_rl = AllocBuffer(sig_rl_size);
if (!sig_rl) {
sts = kEpidMemAllocErr;
break;
}
// fill the SigRl
sts = EpidParseSigRlFile(signed_sig_rl, signed_sig_rl_size, cacert,
sig_rl, &sig_rl_size);
if (kEpidSigInvalid == sts) {
// authentication failure
break;
}
if (kEpidNoErr != sts) {
break;
}
} // if (signed_sig_rl)

-

We use EpidParseSigRlFile to:

-
    -
  • extract the signature based revocation list
    • -
  • validate that the revocation list was signed by the private key corresponding to the provided CA certificate
    • -
  • validate that the size of the input buffer is correct
    • -
  • determine the required size of the revocation list output buffer
    • -
-

To determine the required sig_rl output buffer size, we provide a null pointer for the output buffer when calling EpidParseSigRlFile. This updates sig_rl_size with the required size of the output buffer.

-

After we find out the required size of the sig_rl, we allocate a buffer for the sig_rl. Then we fill the buffer using EpidParseSigRlFile.

-


-

-

Next, we fill the member private key.

-

if (privkey_size == sizeof(PrivKey)) {
priv_key = *(PrivKey*)priv_key_ptr;
} else if (privkey_size == sizeof(CompressedPrivKey)) {
sts = EpidDecompressPrivKey(&pub_key, (CompressedPrivKey*)priv_key_ptr,
&priv_key);
if (kEpidNoErr != sts) {
break;
}
} else {
sts = kEpidErr;
break;
} // if (privkey_size == sizeof(PrivKey))

-

If the member private key is compressed, then we decompress it using EpidDecompressPrivKey before it can be passed to the member APIs. To determine if the member private key is compressed, we check if it is the known size of a compressed key.

-

If the key size is not the size of a known format, we return an error.

-


-

-

Next, we create a pseudo-random number generator.

-

sts = PrngCreate(&prng);
if (kEpidNoErr != sts) {
break;
}

-
Warning
This pseudo-random number generator is included only for demonstration, and should not be used in production code as a source of secure random data. For security, prng should be a cryptographically secure random number generator.
-


-

-

Now that the inputs have been prepared, we create a member context using EpidMemberCreate.

-

sts = EpidMemberCreate(&pub_key, &priv_key,
member_precomp_is_input ? member_precomp : NULL,
PrngGen, prng, &member);
if (kEpidNoErr != sts) {
break;
}

-

If a pre-computation blob is provided to the top level application, we use it. Otherwise, we pass in NULL.

-


-

-

We serialize pre-computed member data using EpidMemberWritePrecomp.

-

sts = EpidMemberWritePrecomp(member, member_precomp);
if (kEpidNoErr != sts) {
break;
}

-

The serialized member pre-computation blob can be used to greatly increase performance of EpidMemberCreate in future sessions if the same member private key is used.

-


-

-

Next, if a basename is specified, we register it with EpidRegisterBaseName so that the member can use it.

-

if (0 != basename_len) {
sts = EpidRegisterBaseName(member, basename, basename_len);
if (kEpidNoErr != sts) {
break;
}
}

-

In a typical use case, to prevent loss of privacy, the member keeps a list of basenames that correspond to authorized verifiers. The member signs a message with a basename only if the basename is in the member's basename list.

-
Warning
The use of a name-based signature creates a platform unique pseudonymous identifier. Because it reduces the member's privacy, the user should be notified when it is used and should have control over its use.
-


-

-

Then we set the hash algorithm to be used by the member using EpidMemberSetHashAlg.

-

sts = EpidMemberSetHashAlg(member, hash_alg);
if (kEpidNoErr != sts) {
break;
}

-

After the hash algorithm is set, future calls to EpidSign will use the same algorithm.

-


-

-

Next, we sign the message, generating an Intel® EPID signature.

-

*sig_len = EpidGetSigSize(sig_rl);
*sig = AllocBuffer(*sig_len);
if (!*sig) {
sts = kEpidMemAllocErr;
break;
}
// sign message
sts = EpidSign(member, msg, msg_len, basename, basename_len, sig_rl,
sig_rl_size, *sig, *sig_len);
if (kEpidNoErr != sts) {
break;
}

-

To create a signature, first we find out the required size of the signature using EpidGetSigSize. Then we allocate a buffer for the signature and fill the buffer using EpidSign.

-

It is important to compute signature size after loading sig_rl because the signature size varies with the size of the SigRL.

-


-

-

Finally, we clean up and exit.

-

sts = kEpidNoErr;
} while (0);
PrngDelete(&prng);
EpidMemberDelete(&member);
if (sig_rl) free(sig_rl);
return sts;
}

-

If we made it past signing without an error, we set the return code appropriately and fall out of the do-while loop. If there was an error earlier, all breaks in the do-while loop bring us to this point with an error status.

-

Next, we free the allocated resources. EpidMemberDelete deletes an existing member context.

-

We return from SignMsg with the success or error status.

-


-

-

This concludes the signmsg walkthrough. Now you should be able to generate an Intel® EPID signature that proves a member's group membership to a verifier without revealing the member's identity.

Verifying an Intel® EPID Signature
-
-
-

This walkthrough of the verifysig example shows you how to use SDK APIs to verify an Intel® EPID 2.0 signature. Verifysig is built during the SDK build.

-

To verify an Intel® EPID 1.1 signature see the example code in verifysig11.c. For information on Intel® EPID 1.1 speciifc APIs see EPID 1.1 support.

-


-

-

First, we include headers so we have access to needed declarations.

-

#include "src/verifysig.h"
#include <stdlib.h>
#include "util/buffutil.h"
#include "util/envutil.h"
#include "epid/verifier/api.h"
#include "epid/common/file_parser.h"

-

The utility headers are used by verifysig for logging and buffer management. The epid/verifier/api.h header provides access to the core verifier APIs, and the epid/common/file_parser.h header provides an API for parsing buffers formatted according to the various IoT Intel® EPID binary file formats.

-


-

-

We define a stub function responsible for checking that the CA certificate is authorized by the root CA.

-

bool IsCaCertAuthorizedByRootCa(void const* data, size_t size) {
(void)data;
(void)size;
return true;
}

-

IsCaCertAuthorizedByRootCa is called from main.c to validate the CA certificate before calling Verify. In an actual implementation, you need to provide an implementation to validate the issuing CA certificate with the CA root certificate before using it in parse functions.

-


-

-

We use Verify to verify an Intel® EPID signature. Verify is a wrapper function that isolates SDK API functionality for the purpose of this walkthrough.

-

EpidStatus Verify(EpidSignature const* sig, size_t sig_len, void const* msg,
size_t msg_len, void const* basename, size_t basename_len,
void const* signed_priv_rl, size_t signed_priv_rl_size,
void const* signed_sig_rl, size_t signed_sig_rl_size,
void const* signed_grp_rl, size_t signed_grp_rl_size,
VerifierRl const* ver_rl, size_t ver_rl_size,
void const* signed_pub_key, size_t signed_pub_key_size,
EpidCaCertificate const* cacert, HashAlg hash_alg,
VerifierPrecomp* verifier_precomp,
bool verifier_precomp_is_input) {

-

The Verify parameters were either sent by the verifier to the member, or they were part of the member's configuration. The exceptions are the sig and sig_len parameters, which we use to input the signature to be verified.

-

The verifier might send the message to the member or there may be another mechanism to choose the message, but the way the message is communicated is outside the scope of the Intel® EPID scheme.

-

We use the parameters verifier_precomp and verifier_precomp_is_input to pass in a pre-computation blob if provided. We can use the pre-computation blob to increase performance when verifying signatures repeatedly with the same group public key.

-

The member and the verifier agree on the message, basename, hash algorithm, and SigRL that the verifier uses for verification.

-
Warning
The use of a name-based signature creates a platform unique pseudonymous identifier. Because it reduces the member's privacy, the user should be notified when it is used and should have control over its use.
-


-

-

Next we do basic variable setup.

-

EpidStatus result = kEpidErr;
VerifierCtx* ctx = NULL;
PrivRl* priv_rl = NULL;
SigRl* sig_rl = NULL;
GroupRl* grp_rl = NULL;
do {
GroupPubKey pub_key = {0};

-

We create pointers to resources to be allocated and we use the do {} while(0) idiom so that we can reliably free resources on return from Verify. We also allocate the group public key on the stack.

-


-

-

Next, we authenticate and extract the group public key using EpidParseGroupPubKeyFile.

-

result = EpidParseGroupPubKeyFile(signed_pub_key, signed_pub_key_size,
cacert, &pub_key);
if (kEpidNoErr != result) {
break;
}

-

EpidParseGroupPubKeyFile takes a buffer containing a group public key in issuer binary format and validates that the public key is signed by the private key that corresponds to the provided CA certificate, reading the key into pub_key in the process.

-


-

-

Next, we create a verifier context using EpidVerifierCreate.

-

result = EpidVerifierCreate(
&pub_key, verifier_precomp_is_input ? verifier_precomp : NULL, &ctx);
if (kEpidNoErr != result) {
break;
}

-

If a pre-computation blob is provided to the top level application, we use it. Otherwise, we pass in NULL.

-


-

-

Then we serialize pre-computed verifier data using EpidVerifierWritePrecomp.

-

result = EpidVerifierWritePrecomp(ctx, verifier_precomp);
if (kEpidNoErr != result) {
break;
}

-

The serialized verifier pre-computation blob can be used to greatly increase performance of EpidVerifierCreate in future sessions if the same group public key is used.

-


-

-

We use EpidVerifierSetHashAlg to indicate the hash algorithm used for verification, which should be the same algorithm that the member used when signing.

-

result = EpidVerifierSetHashAlg(ctx, hash_alg);
if (kEpidNoErr != result) {
break;
}

-

After the hash algorithm is set, future calls to EpidVerify will use the same algorithm.

-


-

-

We use EpidVerifierSetBasename to indicate the basename used for verification, which should be the same one that the member used when signing.

-

result = EpidVerifierSetBasename(ctx, basename, basename_len);
if (kEpidNoErr != result) {
break;
}

-

After the basename is set, future calls to EpidVerify will use the same basename.

-


-

-

Before we verify a signature, we have to configure revocation lists so that we can check to see if a signer's group membership has been revoked.

-
Note
Configured revocation lists are referenced directly by the verifier until a new revocation list is set or the verifier is destroyed. Until the verifier is destroyed, we do not modify the revocation lists.
-


-

-

We set the private key based revocation list using EpidVerifierSetPrivRl.

-

if (signed_priv_rl) {
// authenticate and determine space needed for RL
size_t priv_rl_size = 0;
result = EpidParsePrivRlFile(signed_priv_rl, signed_priv_rl_size, cacert,
NULL, &priv_rl_size);
if (kEpidSigInvalid == result) {
// authentication failure
break;
}
if (kEpidNoErr != result) {
break;
}
priv_rl = AllocBuffer(priv_rl_size);
if (!priv_rl) {
result = kEpidMemAllocErr;
break;
}
// fill the rl
result = EpidParsePrivRlFile(signed_priv_rl, signed_priv_rl_size, cacert,
priv_rl, &priv_rl_size);
if (kEpidNoErr != result) {
break;
}
// set private key based revocation list
result = EpidVerifierSetPrivRl(ctx, priv_rl, priv_rl_size);
if (kEpidNoErr != result) {
break;
}
} // if (signed_priv_rl)

-

We use EpidParsePrivRlFile to:

-
    -
  • extract the private key based revocation list
    • -
  • validate that the revocation list was signed by the private key corresponding to the provided CA certificate
    • -
  • validate that the size of the input buffer is correct
    • -
  • determine the required size of the revocation list output buffer
    • -
-

To determine the required priv_rl buffer size, we provide a null pointer for the output buffer when calling EpidParsePrivRlFile.

-

After we find out the required size of the priv_rl buffer, we allocate memory for it. Then we fill the buffer using EpidParsePrivRlFile.

-


-

-

Next, we set the signature based revocation list using EpidVerifierSetSigRl.

-

if (signed_sig_rl) {
// authenticate and determine space needed for RL
size_t sig_rl_size = 0;
result = EpidParseSigRlFile(signed_sig_rl, signed_sig_rl_size, cacert,
NULL, &sig_rl_size);
if (kEpidSigInvalid == result) {
// authentication failure
break;
}
if (kEpidNoErr != result) {
break;
}
sig_rl = AllocBuffer(sig_rl_size);
if (!sig_rl) {
result = kEpidMemAllocErr;
break;
}
// fill the rl
result = EpidParseSigRlFile(signed_sig_rl, signed_sig_rl_size, cacert,
sig_rl, &sig_rl_size);
if (kEpidNoErr != result) {
break;
}
// set signature based revocation list
result = EpidVerifierSetSigRl(ctx, sig_rl, sig_rl_size);
if (kEpidNoErr != result) {
break;
}
} // if (signed_sig_rl)

-

We use EpidParseSigRlFile to:

-
    -
  • extract the signature based revocation list
    • -
  • validate that the revocation list was signed by the private key corresponding to the provided CA certificate
    • -
  • validate that the size of the input buffer is correct
    • -
  • determine the required size of the revocation list output buffer
    • -
-

To determine the required sig_rl buffer size, we provide a null pointer for the output buffer when calling EpidParseSigRlFile.

-

After we find out the required size of the sig_rl buffer, we allocate memory for it. Then we fill the buffer using EpidParseSigRlFile.

-


-

-

Next, we set the group based revocation list using EpidVerifierSetGroupRl.

-

if (signed_grp_rl) {
// authenticate and determine space needed for RL
size_t grp_rl_size = 0;
result = EpidParseGroupRlFile(signed_grp_rl, signed_grp_rl_size, cacert,
NULL, &grp_rl_size);
if (kEpidSigInvalid == result) {
// authentication failure
break;
}
if (kEpidNoErr != result) {
break;
}
grp_rl = AllocBuffer(grp_rl_size);
if (!grp_rl) {
result = kEpidMemAllocErr;
break;
}
// fill the rl
result = EpidParseGroupRlFile(signed_grp_rl, signed_grp_rl_size, cacert,
grp_rl, &grp_rl_size);
if (kEpidNoErr != result) {
break;
}
// set group revocation list
result = EpidVerifierSetGroupRl(ctx, grp_rl, grp_rl_size);
if (kEpidNoErr != result) {
break;
}
} // if (signed_grp_rl)

-

We use EpidParseGroupRlFile to:

-
    -
  • extract the group based revocation list
    • -
  • validate that the revocation list was signed by the private key corresponding to the provided CA certificate
    • -
  • validate that the size of the input buffer is correct
    • -
  • determine the required size of the revocation list output buffer
    • -
-

To determine the required grp_rl buffer size, we provide a null pointer for the output buffer when calling EpidParseGroupRlFile.

-

After we find out the required size of the grp_rl buffer, we allocate memory for it. Then we fill the buffer using EpidParseGroupRlFile.

-


-

-

Next, we set the verifier blacklist using EpidVerifierSetVerifierRl.

-

if (ver_rl) {
// set verifier based revocation list
result = EpidVerifierSetVerifierRl(ctx, ver_rl, ver_rl_size);
if (kEpidNoErr != result) {
break;
}
}

-

The verifier is responsible for ensuring that the verifier revocation list is authorized. Validating it is outside the scope of this example.

-


-

-

Next, we use EpidVerify to verify that the Intel® EPID signature was created by a valid member of a group in good standing.

-

result = EpidVerify(ctx, sig, sig_len, msg, msg_len);
if (kEpidNoErr != result) {
break;
}

-

-

Finally, we clean up and exit.

-

} while (0);
// delete verifier
EpidVerifierDelete(&ctx);
if (priv_rl) free(priv_rl);
if (sig_rl) free(sig_rl);
if (grp_rl) free(grp_rl);
return result;
}

-

If we made it past verification without an error, we set the return code appropriately and fall out of the do-while loop. If there was an error earlier, all breaks in the do-while loop bring us to this point with an error status.

-

Then we free the allocated resources. EpidVerifierDelete deletes the verifier context.

-

After deleting the verifier context, we can also delete the revocation lists.

-

We return from Verify with the success or error status.

-


-

-

This concludes the verifysig walkthrough. Now you should be able to verify an Intel® EPID signature using the SDK APIs.

-

To learn more about the SDK APIs see the API Reference. To learn more about the Intel® EPID Scheme see Introduction to the Intel® EPID Scheme in the documentation.

Detailed Description

-

Elliptic curve group operations.

-

Provides APIs for working with Elliptic curve groups. Elliptic curve groups allow simple mathematical operations based on points that lie on a defined elliptic curve. The results of these operations also lie on the same curve.

-

Curves themselves are defined based on elements (FfElement) of a finite field (FiniteField).

Detailed Description

-

Intel(R) EPID 1.1 Verifier functionality.

-

To verify signatures coming from member devices that belong to an Intel® EPID 1.1 group, you need to use Intel® EPID 1.1 verifier APIs.

-

If you are acting as a verifier for both Intel® EPID 1.1 and 2.0 members, you can determine if you need version 1.1 or 2.0 verification by checking the Intel® EPID version field in the group public key file (see EpidParseFileHeader). You can also check the version in other binary issuer material, such as the GroupRL and SigRL.

-

The 1.1 verifier APIs take a verifier context as input. Each verifier context (Epid11VerifierCtx) represents a verifier for a single group.

-

The Intel® EPID 1.1 specification does not provide hash algorithm selection and verifier blacklist revocation. Therefore, APIs such as EpidVerifierSetHashAlg and EpidVerifierSetVerifierRl are not available.

-

You can find the Intel® EPID 1.1 API headers in the 1.1 directories, for example, epid/verifier/1.1/api.h.

-

Intel® EPID 1.1 APIs and data structures are indicated with the "Epid11" prefix. For example, the Intel® EPID 1.1 version of EpidParseGroupPubKeyFile is called Epid11ParseGroupPubKeyFile, and the Intel® EPID 1.1 version of GroupRl is Epid11GroupRl.

bool Epid11AreSigsLinked (Epid11BasicSignature const * sig1,
Epid11BasicSignature const * sig2 
)
-
- -

Determines if two Intel(R) EPID 1.1 signatures are linked.

-

The Intel(R) EPID scheme allows signatures to be linked. If basename option is specified when signing signatures with the same basename will be linkable. This linking capability allows the verifier, or anyone, to know whether two Intel(R) EPID signatures are generated by the same member.

-

This API supports Intel(R) EPID 1.1 verification.

-
Parameters
- - - -
[in]sig1A basic signature.
[in]sig2A basic signature.
-
-
-
Returns
bool
-
Return values
- - - -
trueif the signatures were generated by the same member
falseif it couldn't be determined if the signatures were generated by the same member
-
-
-
Note
The input signatures should be verified using Epid11VerifyBasicSig() before invocation. Behavior is undefined if either of the signatures cannot be verified.

EpidStatus Epid11VerifierCreate (Epid11GroupPubKey const * pub_key,
Epid11VerifierPrecomp const * precomp,
Epid11VerifierCtx ** ctx 
)
-
- -

Creates a new Intel(R) EPID 1.1 verifier context.

-

Must be called to create the verifier context that is used by other "Verifier" APIs.

-

Allocates memory for the context, then initialize it.

-

Epid11VerifierDelete() must be called to safely release the member context.

-
Parameters
- - - - -
[in]pub_keyThe group certificate.
[in]precompOptional pre-computed data. If NULL the value is computed internally and is readable using Epid11VerifierWritePrecomp().
[out]ctxNewly constructed verifier context.
-
-
-
Returns
EpidStatus
-
Note
If the result is not kEpidNoErr the content of ctx is undefined.

void Epid11VerifierDelete (Epid11VerifierCtx ** ctx)
-
- -

Deletes an existing Intel(R) EPID 1.1 verifier context.

-

Must be called to safely release a verifier context created using Epid11VerifierCreate().

-

De-initializes the context, frees memory used by the context, and sets the context pointer to NULL.

-
Parameters
- - -
[in,out]ctxThe verifier context. Can be NULL.

-
- -

Sets the basename to be used by a verifier.

-

This API allows setting a zero length base name.

-
Warning
Not all members in the Intel(R) EPID 1.1 ecosystem may support zero length basenames. They may interpret a zero length basename as random base.
-
Parameters

EpidStatus Epid11VerifierSetGroupRl (Epid11VerifierCtx * ctx,
Epid11GroupRl const * grp_rl,
size_t grp_rl_size 
)
-
- -

Sets the Intel(R) EPID 1.1 group based revocation list.

-

The caller is responsible to for ensuring the revocation list is authorized, e.g signed by the issuer. The caller is also responsible checking the version of the revocation list. The call will fail if trying to set an older version of the revocation list than was last set.

-

This API supports Intel(R) EPID 1.1 verification.

-
Attention
The memory pointed to by grp_rl will be accessed directly by the verifier until a new list is set or the verifier is destroyed. Do not modify the contents of this memory. The behavior of subsequent operations that rely on the revocation list will be undefined if the memory is modified.
-
-It is the responsibility of the caller to free the memory pointed to by grp_rl after the verifier is no longer using it.
-
Parameters
- - - - -
[in,out]ctxThe verifier context.
[in]grp_rlThe group based revocation list.
[in]grp_rl_sizeThe size of the group based revocation list in bytes.
-
-
-
Returns
EpidStatus
-
Note
If the result is not kEpidNoErr the group based revocation list pointed to by the verifier is undefined.

EpidStatus Epid11VerifierSetSigRl (Epid11VerifierCtx * ctx,
Epid11SigRl const * sig_rl,
size_t sig_rl_size 
)
-
- -

Sets the Intel(R) EPID 1.1 signature based revocation list.

-

The caller is responsible to for ensuring the revocation list is authorized, e.g signed by the issuer. The caller is also responsible checking the version of the revocation list. The call will fail if trying to set an older version of the revocation list than was last set.

-

This API supports Intel(R) EPID 1.1 verification.

-
Attention
The memory pointed to by sig_rl will be accessed directly by the verifier until a new list is set or the verifier is destroyed. Do not modify the contents of this memory. The behavior of subsequent operations that rely on the revocation list will be undefined if the memory is modified.
-
-It is the responsibility of the caller to free the memory pointed to by sig_rl after the verifier is no longer using it.
-
Parameters
- - - - -
[in,out]ctxThe verifier context.
[in]sig_rlThe signature based revocation list.
[in]sig_rl_sizeThe size of the signature based revocation list in bytes.
-
-
-
Returns
EpidStatus
-
Note
If the result is not kEpidNoErr the signature based revocation list pointed to by the verifier is undefined.

EpidStatus EpidRegisterBaseName (MemberCtx * ctx,
void const * basename,
size_t basename_len 
)
-
- -

Registers a basename with a member.

-

To prevent loss of privacy, the member keeps a list of basenames (corresponding to authorized verifiers). The member signs a message with a basename only if the basename is in the member's basename list.

-
Warning
The use of a name-based signature creates a platform unique pseudonymous identifier. Because it reduces the member's privacy, the user should be notified when it is used and should have control over its use.
-
Parameters
- - - - -
[in]ctxThe member context.
[in]basenameThe basename.
[in]basename_lenLength of the basename.
-
-
-
Returns
EpidStatus
-
Return values
- - -
kEpidDuplicateErrThe basename was already registered.

FpElemStr const * f,
BitSupplier rnd_func,
void * rnd_param,
HashAlg hash_alg,
JoinRequest * join_request 
)
-
- -

Creates a request to join a group.

-

The created request is part of the interaction with an issuer needed to join a group. This interaction with the issuer is outside the scope of this API.

-
Parameters
- - - - - - - - -
[in]pub_keyThe group certificate of group to join.
[in]niThe nonce chosen by issuer as part of join protocol.
[in]fA randomly selected integer in [1, p-1].
[in]rnd_funcRandom number generator.
[in]rnd_paramPass through context data for rnd_func.
[in]hash_algThe hash algorithm to be used.
[out]join_requestThe join request.
-
-
-
Returns
EpidStatus
-
Warning
For security rnd_func should be a cryptographically secure random number generator.
-
Note
The default hash algorithm in Member is SHA-512. This is the recommended option if you do not override the hash algorithm elsewhere.
-
-If the result is not kEpidNoErr, the content of join_request is undefined.

Detailed Description

-

SDK data types.

-

Defines serialized data types used by the SDK.

-

Most of the types defined here are fixed size binary buffers of various sizes that are semantically mapped to the types of various inputs to the Intel(R) EPID APIs.

-

For example GtElemStr is a 384 byte buffer that represents a serialized value that is compatible with a FfElement belonging to the FiniteField GT.

Detailed Description

-

Verifier functionality.

-

Defines the APIs needed by Intel(R) EPID verifiers. Each verifier context (VerifierCtx) represents a verifier for a single group.

-

Function Documentation

- -
-
- - - - - - - - - - - - - - - - - - -
bool EpidAreSigsLinked (BasicSignature const * sig1,
BasicSignature const * sig2 
)
-
- -

Determines if two signatures are linked.

-

The Intel(R) EPID scheme allows signatures to be linked. If basename option is specified when signing, signatures with the same basename are linkable. This linking capability allows the verifier, or anyone, to know whether two Intel(R) EPID signatures are generated by the same member.

-
Parameters
- - - -
[in]sig1A basic signature.
[in]sig2A basic signature.
-
-
-
Returns
bool
-
Return values
- - - -
trueif the signatures were generated by the same member
falseif it couldn't be determined if the signatures were generated by the same member
-
-
-
Note
The input signatures should be verified using EpidVerifyBasicSig() before invocation. Behavior is undefined if either of the signatures cannot be verified.

EpidStatus EpidVerifierSetGroupRl (VerifierCtx * ctx,
GroupRl const * grp_rl,
size_t grp_rl_size 
)
-
- -

Sets the group based revocation list.

Detailed Description

-

Finite field operations.

-

provides APIs for working with finite fields. Finite fields allow simple mathematical operations based on a finite set of discrete values. The results of these operations are also contained in the same set.

-

A simple example of a finite field is all integers from zero that are less than a given value.

-

The elements (FfElement) of a finite field can be used in a variety of simple mathematical operations that result in elements of the same field.
