Upgraded to OpenSSL 3.0.14. Upgraded Intel(R) Integrated Performance Primitives (IPP) Cryptography library to version 2021.12.1. Supported FIPS 140-3 Certifiable IPP Crypto based Trusted Library. Upgraded Intel SGX Architecture Enclaves based on new IPP crypto library. Upgraded Intel DCAP Quote Verification Enclave to integrate OpenSSL/SgxSSL 3.0.14. Removed Intel DCAP PCCS from repository. Added Ubuntu* 24.04 LTS 64-bit Server support. Fixed bug. Note that PCCS is not available from this release. Please follow DCAP installation guide to use `PCCSAdminTool` to retrieve the attestation collaterals or use old version PCCS. Signed-off-by: Li, Xun <xun.li@intel.com>
-----------------------
Purpose of Cxx11SGXDemo
-----------------------
The project demonstrates serveral C++11 features inside the Enclave:
- lambda expressions;
- rvalue references and move semantics;
- automatic type deduction with auto and decltype;
- nullptr type;
- strongly typed enum classes;
- Range-based for statements;
- static_assert keyword for compile-time assertion;
- initializer lists and uniform initialization syntax;
- New virtual function controls: override, final, default, and delete;
- delegating constructors;
- new container classes (unordered_set, unordered_map, unordered_multiset, and unordered_multimap);
- tuple class;
- function object wrapper;
- atomic, mutexes, condition_variables;
- new smart pointer classes: shared_ptr, unique_ptr;
- new c++ algorithms: all_of, any_of, none_of;
- variadic templates;
- SFINAE;
---------------------------------------------
How to Build/Execute the C++11 sample program
---------------------------------------------
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<Enclave_private_test.pem> automatically when you build the project.
b. Rename your test key(3072-bit RSA private key) to <Enclave_private_test.pem> and put it under the <Enclave> folder.
3. Make sure your environment is set:
$ source ${sgx-sdk-install-path}/environment
4. 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
5. Execute the binary directly:
$ ./app
6. Remember to "make clean" before switching build mode
-------------------------------------------------
Launch token initialization
-------------------------------------------------
If using libsgx-enclave-common or sgxpsw under version 2.4, an initialized variable launch_token needs to be passed as the 3rd parameter of API sgx_create_enclave. For example,
sgx_launch_token_t launch_token = {0};
sgx_create_enclave(ENCLAVE_FILENAME, SGX_DEBUG_FLAG, launch_token, NULL, &global_eid, NULL);
