Supported the Key Separation and Sharing (KSS) feature in Simulation mode. Upgraded to OpenSSL 1.1.1t. Upgraded Intel(R) SGX Quote Verification Enclave to integrate SgxSSL/OpenSSL version 1.1.1t. Added new API in quote verification library to extract FMSPC (Family-Model-SteppingPlatform-CustomSKU) value from ECDSA quote. Added Rust support for SGX ECDSA quote generation. Added Linux kernel 5.19 support in TDX R3AAL (Ring 3 Attestation Abstraction Layer). Removed Protobuf in TDX QGS (Quote Generation Service) and R3AAL (Ring 3 Attestation Abstraction Layer). Fixed bugs. Signed-off-by: Li, Xun <xun.li@intel.com>
-----------------------
Purpose of Cxx14SGXDemo
-----------------------
The project demonstrates several C++14 features inside the Enclave:
- standard user-defined literals
- tuple addressing via type
- std::make_unique
- std::integral_constant
- std::integer_sequence
- std::cbegin/std::cend and std::crbegin/std::crend
- std::exchange
- std::is_final
- std:quoted
- std::equal/std::mismatch/std::is_permutation new overloads
- heterogeneous lookup
- function return type deduction
- variable template
- binary literals
- digit separators
- generic lambdas
- lambda capture expressions
- attribute [[deprecated]]
- aggregate member initialization
- relaxed constexpr restrictions
- alternate type deduction on declaration
---------------------------------------------
How to Build/Execute the C++14 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);
