Upgraded to OpenSSL 3.0.10. Added interoperable RA-TLS support which follows CCC design. Enhanced Protect File System performance and added additional dependency `libsgx_pthread.a`. Added the Constant Time instruction Decoder (CTD) into the default AEX-Notify mitigation handler in order to prevent the introduction of any additional subtle sidechannel leakages within the default handler. Added Mistletoe 3 mitigations to the IPP Cryptography Library to the AES-ECB, AESGCM, and AES-CMAC algorithms. These have been incorporated transparently into the `sgx_tcrypto` library. Resigned all Intel® SGX Architecture Enclaves. Upgraded Intel SGX Quote Verification Enclave to integrate OpenSSL/SgxSSL 3.0.10. Added Attestation Library support for Intel(R) TDX Migration TD. Added Rust wrapper for low-level Quote Generation APIs. Enabled `SE_TRACE` log in release binary. Updated Rust QVL wrapper to use native Rust structure for quote verification collateral. Added a limitation in the DCAP QVL to only allow the user to set the QvE load policy once. Fixed bugs. Signed-off-by: Li, Xun <xun.li@intel.com>
---------------------------
The project aims to demo SGX local attestation flow.
------------------------------------
How to Build the Sample Code
------------------------------------
1. Install Intel(R) Software Guard Extensions (Intel(R) SGX) SDK for Linux* OS
2. Enclave test key(two options):
a. Install openssl first, then the project will generate a test key<EnclaveInitiator_private_test.pem>/<EnclaveResponder_private_test.pem> automatically when you build the project.
b. Rename your test key(3072-bit RSA private key) to <EnclaveInitiator_private_test.pem>/<EnclaveResponder_private_test.pem> and put it under the <EnclaveInitiator>/<EnclaveResponder> folder.
3. Build the project with the prepared Makefile:
a. Hardware Mode, Debug build:
$ make
b. Hardware Mode, Pre-release build:
$ make SGX_PRERELEASE=1 SGX_DEBUG=0
c. Hardware Mode, release build:
$ make SGX_DEBUG=0
d. Simulation Mode, Debug build:
$ make SGX_MODE=SIM
e. Simulation Mode, Pre-release build:
$ make SGX_MODE=SIM SGX_PRERELEASE=1 SGX_DEBUG=0
f. Simulation Mode, Release build:
$ make SGX_MODE=SIM SGX_DEBUG=0
g. Use Local Attestation 2.0 protocol, Hardware Mode, Debug build:
$ make LAv2=1
Note: Local Attestation 2.0 protocol will be used if 'LAv2' is defined.
When build is successful, you can find executable binaries in "bin" sub-folder.
------------------------------------
How to Execute the Sample Code
------------------------------------
1. Install SGX driver and PSW for Linux* OS
2. If you want to try local attestation flow from two process, you can goto "bin" sub-folder
a. run "./appresponder".
It would launch a process to act as local attestation responder.
b. run "./appinitiator"
It would launch a process to act as local attestation initator.
3. If you want to try local attestation flow from one process, you can goto "bin" sub-folder and run "./app"
------------------------------------
How to Get Signed Enclave's MRSIGNER
------------------------------------
1. Install Intel(R) Software Guard Extensions (Intel(R) SGX) SDK for Linux* OS
2. Execute blow command to get your signed enclave's MRSIGNER:
<SGX_SDK Installation Path>/bin/x64/sgx_sign dump -enclave <Signed Enclave> -dumpfile mrsigner.txt
3. Find the signed enclave's MRSIGNER in the mrsigner.txt(mrsigner->value:)
