Sgx_Java

The project demonstrates several fundamental example APIs created with Java Native Interface (JNI). These example APIs enable JAVA to perform enclave operations in Intel(R) Software Guard Extensions (SGX).

How to Build/Execute the Sample Code

• Install Intel(R) SGX SDK for Linux* OS
• Install OpenJDK (sudo apt-get install openjdk-8-jdk)
• export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`pwd`
• Build the project with the prepared Makefile:
  1. Hardware Mode, Debug build: $ make
  2. Hardware Mode, Pre-release build: $ make SGX_PRERELEASE=1 SGX_DEBUG=0
  3. Hardware Mode, Release build: $ make SGX_DEBUG=0
  4. Simulation Mode, Debug build: $ make SGX_MODE=SIM
  5. Simulation Mode, Pre-release build: $ make SGX_MODE=SIM SGX_PRERELEASE=1 SGX_DEBUG=0
  6. Simulation Mode, Release build: $ make SGX_MODE=SIM SGX_DEBUG=0
• Execute example Java app: $ java JavaApp [size of byte array]
• Remember to "make clean" before switching build mode

Sgx_Python

The project demonstrates several fundamental example APIs created with Python Ctypes. These example APIs enables Python to perform enclave operations in Intel(R) Software Guard Extensions (SGX): - Initialize and destroy an enclave. - Generate a random byte array using SGX trusted library function (sgx_read_rand).

How to Build/Execute the Sample Code

• Install Intel(R) SGX SDK for Linux* OS
• Install Ctypes
• export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`pwd`
• Build the project with the prepared Makefile:
  1. Hardware Mode, Debug build: $ make
  2. Hardware Mode, Pre-release build: $ make SGX_PRERELEASE=1 SGX_DEBUG=0
  3. Hardware Mode, Release build: $ make SGX_DEBUG=0
  4. Simulation Mode, Debug build: $ make SGX_MODE=SIM
  5. Simulation Mode, Pre-release build: $ make SGX_MODE=SIM SGX_PRERELEASE=1 SGX_DEBUG=0
  6. Simulation Mode, Release build: $ make SGX_MODE=SIM SGX_DEBUG=0
• Execute example Python app: $ python PythonApp.py [optional: size of byte array]
• Remember to "make clean" before switching build mode

Brief Introduction of Each Folder and File

• Enclave: defines the functions running in the enclave
• LibSgxC: defines ecall/ocall functions that communicates to the enclave
• LibSgxPython: python ctypes that wraps the shared library
• PythonApp.py: the example python application
