SignEnclave

The project demonstrates several fundamental usages of Intel(R) Software Guard Extensions (Intel(R) SGX) SDK:

  • Initializing and destroying an enclave
  • Creating ECALLs or OCALLs
  • Using ECDSA from SGXs cryptographic API

Getting Started

  1. Install Intel(R) SGX SDK for Linux OS
  2. Make sure your environment is set:
source ${sgx-sdk-install-path}/environment
  1. Build the code
cmake -S . -B build
cmake --build build
cd build

Running with Docker

Alternatively, if your processor does not support SGX, you can easily build and run it inside a Docker container.

  1. Install the Remote-Containers extension of VSCode.
  2. Reopen the workspace inside the devcontainer (command Remote-Containers: Open folder in container)

Inside the container, you can build the code in simulation mode:

  1. cmake -DSGX_HW=OFF -DSGX_MODE=Debug -DCMAKE_BUILD_TYPE=Debug -S . -B build
  2. cd build && make -j 5

Example Usage
