This repository provides two types of SEAL

• source files are placed in native/origin/
• to install this,

    chmod 777 ./install_origin.sh
    sudo ./install_origin.sh

• Install path is ${home}/myseal_origin

• source files are placed in native/sgx/
• (prerequisite) SGXSDK should be installed in /opt/intel/sgxsdk
• to install this,

    cmake -S . -B build_sgx -DSEAL_BUILD_DEPS=OFF -DSEAL_USE_MSGSL=OFF -DSEAL_USE_ZSTD=OFF -DSEAL_USE_ZLIB=OFF -DSEAL_USE_CXX17=OFF -DSEAL_USE_INTRIN=OFF -DSEAL_USE_EXPLICIT_BZERO=OFF -DSEAL_SRC_PATH=sgx -DCMAKE_INSTALL_PREFIX=~/myseal_sgx

• Then modify build_sgx/CMakeCache.txt (CMakeLists.txt will be updated soon),
  • Set CMAKE_CXX_FLAGS:STRING=-nostdinc -fvisibility=hidden -fpie -fstack-protector -I/opt/intel/sgxsdk/include -I/opt/intel/sgxsdk/include/libcxx -I/opt/intel/sgxsdk/include/tlibc -nostdinc++
  • Set CMAKE_C_FLAGS:STRING=-nostdinc -fvisibility=hidden -fpie -fstack-protector -I/opt/intel/sgxsdk/include -I/opt/intel/sgxsdk/include/libcxx -I/opt/intel/sgxsdk/include/tlibc
  • Set CMAKE_INSTALL_OLDINCLUDEDIR:PATH=/opt/intel/sgxsdk/include
• continue,

    cmake --build build_sgx
    sudo cmake --install build_sgx

• Install path is ${home}/myseal_sgx

• Add set_coeff method in PublicKey, SecretKey, Plaintext, Ciphertext and DynArray
• Add ct_data, pt_data struct in ciphertext.h and plaintext.h, respectively
• Remove features related to BFV scheme
• [Modified version] Remove features related to iostream, Serialization
