# Hardware Requirements

  1. Go to your BIOS menu
  2. Enable SGX (Software controlled is not enough)
  3. Disable Secure Boot

# Software Requirements

First, make sure you have Rust installed: https://www.rust-lang.org/tools/install

  • Once Rust is installed, install the nightly toolchain:

    rustup toolchain install nightly
    

Then you can use this script (or run the commands one-by-one), which was tested on Ubuntu 20.04 with SGX driver/sdk version 2.9 intended for Ubuntu 18.04:

UBUNTUVERSION=$(lsb_release -r -s | cut -d '.' -f 1)

if (($UBUNTUVERSION < 16)); then
	echo "Your version of Ubuntu is not supported. Must have Ubuntu 16.04 and up. Aborting installation script..."
	exit 1
elif (($UBUNTUVERSION < 18)); then
	DISTRO='xenial'
else
	DISTRO='bionic'
fi

   # 1. Go to https://download.01.org/intel-sgx/sgx-linux
   # 2. Step into the latest version
   # 3. Step into `distro/$LATEST_UBUNTU_YOU_SEE_THERE`

sudo apt install -y libsgx-enclave-common libsgx-enclave-common-dev libsgx-urts sgx-aesm-service libsgx-uae-service libsgx-launch libsgx-aesm-launch-plugin libsgx-ae-le autoconf libtool

Note that sometimes after a system reboot you'll need to reinstall the driver (usually after a kernel upgrade):

sudo $HOME/.sgxsdk/sgx_linux_x64_driver_*.bin

# Testing your SGX setup

  1. For node runners, by using sgx-detect:

    sudo apt install -y libssl-dev protobuf-compiler
    cargo +nightly install fortanix-sgx-tools sgxs-tools
    
    sgx-detect
    

    Should print at the end:

    ✔  Able to launch enclaves
       ✔  Debug mode
       ✔  Production mode (Intel whitelisted)
    
    You're all set to start running SGX programs!
    
  2. For enclave developers, by compiling a hello-rust project:

    git clone --depth 1 -b v1.1.2 git@github.com:apache/incubator-teaclave-sgx-sdk.git
    
    cd incubator-teaclave-sgx-sdk/samplecode/hello-rust
    perl -i -pe 's/SGX_SDK \?=.+/SGX_SDK ?= \$(HOME)\/.sgxsdk\/sgxsdk/' Makefile
    make
    cd bin
    ./app
    

    Should print somting similar to this:

    [+] Init Enclave Successful 2!
    This is a normal world string passed into Enclave!
    This is a in-Enclave Rust string!
    gd: 1 0 0 1
    static: 1 eremove: 0 dyn: 0
    EDMM: 0, feature: 9007268790009855
    supported sgx
    [+] say_something success...
    

# Uninstall

To uninstall the Intel(R) SGX Driver, run:

sudo /opt/intel/sgxdriver/uninstall.sh

The above command produces no output when it succeeds. If you want to verify that the driver has been uninstalled, you can run the following, which should print SGX Driver NOT installed:

ls /dev/isgx &>/dev/null && echo "SGX Driver installed" || echo "SGX Driver NOT installed"

To uninstall the SGX SDK, run:

sudo "$HOME"/.sgxsdk/sgxsdk/uninstall.sh
rm -rf "$HOME/.sgxsdk"

To uninstall the rest of the dependencies, run:

sudo apt purge -y libsgx-enclave-common libsgx-enclave-common-dev libsgx-urts sgx-aesm-service libsgx-uae-service libsgx-launch libsgx-aesm-launch-plugin libsgx-ae-le
