Added support for the Key Separation and Sharing (KSS) feature. Provided a set of new encryption and decryption functions such as sgx_hmac256_*. Provided a new untrusted API: sgx_get_target_info. Provided a new untrusted API: sgx_create_enclave_from_buffer_ex. Updated the cryptography library and Architecture Enclaves to use Intel(R) Integrated Performance Primitives Cryptography 2019 Update 1. Fixed bugs. 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. Make sure your environment is set:
$ source ${sgx-sdk-install-path}/environment
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
4. Execute the binary directly:
$ ./app
5. Remember to "make clean" before switching build mode
