This sample demonstrates how to execute Remote Attestation on SGX with librats and run it with iwasm. It can only build on SGX supported processors, please check it.
Before staring, we need to download and intall SGX SDK and SGX DCAP Library referring to this guide.
The following command is the example of the SGX environment installation on ubuntu18.04.
$ cd $HOME
$ # Set your platform, you can get the platforms list on
$ # https://download.01.org/intel-sgx/latest/linux-latest/distro
$ SGX_PALTFORM=ubuntu18.04-server
$ SGX_SDK_VERSION=2.17.100.3
$ SGX_DRIVER_VERSION=1.41
$ # install SGX Driver
$ wget https://download.01.org/intel-sgx/latest/linux-latest/distro/$SGX_PALTFORM/sgx_linux_x64_driver_$SGX_DRIVER_VERSION.bin
$ chmod +x sgx_linux_x64_driver_$SGX_DRIVER_VERSION.bin
$ sudo ./sgx_linux_x64_driver_$SGX_DRIVER_VERSION.bin
$ # install SGX SDK
$ wget https://download.01.org/intel-sgx/latest/linux-latest/distro/$SGX_PALTFORM/sgx_linux_x64_sdk_$SGX_SDK_VERSION.bin
$ chmod +x sgx_linux_x64_sdk_$SGX_SDK_VERSION.bin
$ sudo ./sgx_linux_x64_sdk_$SGX_SDK_VERSION.bin
$ # install SGX DCAP Library
$ echo 'deb [arch=amd64] https://download.01.org/intel-sgx/sgx_repo/ubuntu bionic main' | sudo tee /etc/apt/sources.list.d/intel-sgx.list > /dev/null
$ wget -O - https://download.01.org/intel-sgx/sgx_repo/ubuntu/intel-sgx-deb.key | sudo apt-key add -
$ sudo apt update
$ sudo apt install libsgx-uae-service libsgx-dcap-default-qpl-dev libsgx-dcap-ql-dev libsgx-dcap-quote-verify-dev$ mkdir build && cd build
$ cmake ..
$ make
$ # run the sample
$ ./iwasm wasm-app/test.wasmThe sample will print the evidence in json and "Evidence is trusted." by default.
