Intel(R) Software Guard Extensions for Linux* OS

linux-sgx

Introduction

Intel(R) Software Guard Extensions (Intel(R) SGX) is an Intel technology for application developers seeking to protect select code and data from disclosure or modification.

The Linux Intel SGX software stack is comprised of the Intel SGX driver, the Intel SGX SDK, and the Intel SGX Platform Software. The Intel SGX SDK and Intel SGX PSW are hosted in the linux-sgx project.

The linux-sgx-driver project hosts the out-of-tree driver for the Linux Intel SGX software stack, which will be used until the driver upstreaming process is complete.

Note This repository includes a subset of the Intel(R) IPP Cryptography library under external/crypto_px. It is provided as reference implementation for the cryptographic primitives used in SDK and PSW. They are written in pure C and are not optimized for performance. Instructions are provided below for building the SDK and PSW with both precompiled optimized IPP binaries and the non-optimized source code version.

Build and Install the Intel(R) SGX Driver

Follow the instructions in the linux-sgx-driver project to build and install the Intel SGX driver.

Build the Intel(R) SGX SDK and Intel(R) SGX PSW Package

Prerequisites:

Ensure that you have the following required operating systems:
- Ubuntu* Desktop-16.04-LTS 64bits
- Red Hat Enterprise Linux Server release 7.2 64bits
- CentOS 7.3.1611 64bits

Use the following command(s) to install the required tools to build Intel(R) SGX SDK:

On Ubuntu 16.04:

$ sudo apt-get install build-essential ocaml automake autoconf libtool wget python

On Red Hat Enterprise Linux 7.2 and CentOS 7.3:

$ sudo yum groupinstall 'Development Tools'
$ sudo yum install ocaml wget python

Use the following command to install additional required tools to build Intel(R) SGX PSW:

On Ubuntu 16.04:

$ sudo apt-get install libssl-dev libcurl4-openssl-dev protobuf-compiler libprotobuf-dev

On Red Hat Enterprise Linux 7.2 and CentOS 7.3:

$ sudo yum install openssl-devel libcurl-devel protobuf-compiler protobuf-devel

Use the script download_prebuilt.sh inside source code package to download prebuilt binaries to prebuilt folder
You may need set https proxy for wget tool used by the script (such as export https_proxy=http://test-proxy:test-port)
```
$ ./download_prebuilt.sh
```

Build the Intel(R) SGX SDK and Intel(R) SGX PSW

The following steps describe how to build the Intel SGX SDK and PSW. You can build the project according to your requirement.

To build both Intel SGX SDK and PSW with default configuration, enter the following command:
You can find the tools and libraries generated in the build/linux directory.
Note: You can also go to the sdk folder and use the make command to build the Intel SGX SDK component only. However, the building of PSW component is dependent on the building result of Intel SGX SDK.
```
$ make  
```
The default build uses precompiled optimized libraries which have been downloaded by the script ./download_prebuilt.sh. You can also use the non-optimized source code version implementation instead by entering the following command:
```
$ make USE_OPT_LIBS=0
```
To build Intel SGX SDK and PSW with debug information, enter the following command:
```
$ make DEBUG=1
```
To clean the files generated by previous make command, enter the following command:
```
$ make clean
```
The build above uses prebuilt Intel(R) Architecture Enclaves(LE/PvE/QE/PCE/PSE-OP/PSE-PR) and applet(PSDA) - the files psw/ae/data/prebuilt/libsgx_*.signed.so and psw/ae/data/prebuilt/PSDA.dalp, which have been signed by Intel in advance. To build those enclaves by yourself (without a signature), first you need to build both Intel SGX SDK and PSW with the default configuration. After that, you can build each Architecture Enclave by using the make command from the corresponding folder:
```
$ cd psw/ae/le
$ make
```

Build Intel(R) SGX SDK Installer

To build Intel(R) SGX SDK installer, enter the following command:

$ make sdk_install_pkg

You can find the generated Intel SGX SDK installer sgx_linux_x64_sdk_${version}.bin located under linux/installer/bin/, where ${version} refers to the version number.

Build Intel(R) SGX PSW Installer

To build Intel(R) SGX PSW installer, enter the following command:

$ make psw_install_pkg

You can find the generated Intel SGX PSW installer sgx_linux_x64_psw_${version}.bin located under linux/installer/bin/, where ${version} refers to the version number.

Install Intel(R) SGX SDK

Prerequisites

Ensure that you have the following required operating systems:
- Ubuntu* Desktop-16.04-LTS 64bits
- Red Hat Enterprise Linux Server release 7.2 64bits
- CentOS 7.3.1611 64bits
Use the following command to install the required tool to use Intel(R) SGX SDK:
- On Ubuntu 16.04:
```
$ sudo apt-get install build-essential python
```
- On Red Hat Enterprise Linux 7.2 and CentOS 7.3:
```
$ sudo yum groupinstall 'Development Tools'

```

Install Intel(R) SGX SDK

To install Intel(R) SGX SDK, execute the installer with root privilege:

$ cd linux/installer/bin
$ sudo ./sgx_linux_x64_sdk_${version}.bin

Test Intel(R) SGX SDK Package with the Sample Codes

Copy the sample codes installed by Intel(R) SGX SDK package into your work folder, such as:
```
$ cp -r /opt/intel/sgxsdk/SampleCode ~
```
Compile and run each sample codes in the simulation mode to make sure the package works well:
```
$ cd SampleCode/LocalAttestation
$ make SGX_MODE=SIM
$ ./app
```
Use similar commands for other sample codes.

Compile and Run the Sample Codes in the Hardware Mode

If you use an Intel SGX hardware enabled machine, you can run the sample codes in the hardware mode. Ensure that you install Intel(R) SGX driver and Intel(R) SGX PSW installer on the machine.
See the topic, Build and Install the Intel(R) SGX Driver, on how to install the Intel(R) SGX driver.
See the topic, Install Intel(R) SGX PSW, on how to install the PSW package.
Copy the sample codes installed by the Intel(R) SGX SDK package into your work folder, such as:
```
$ cp -r /opt/intel/sgxsdk/SampleCode ~
```
Compile and run each sample codes in the hardware mode, debug build:
```
$ cd SampleCode/LocalAttestation
$ make
$ ./app
```
Use similar commands for other sample codes.

Install Intel(R) SGX PSW

Prerequisites

- On Red Hat Enterprise Linux 7.2:
  Update kernel version to kernel-3.10.0-514.el7 or newer on Red Hat Enterprise Linux 7.2.
```
$ sudo yum update kernel
```
  Download iclsClient and install it using the following commands:

$ cmake .;make;sudo make install;sudo systemclt enable jhi
```
- On Red Hat Enterprise Linux 7.2 and CentOS 7.3:
```
$ sudo yum install libuuid-devel libxml2-devel cmake
$ cmake .;make;sudo make install;sudo systemclt enable jhi
```

Install Intel(R) SGX PSW

To install Intel(R) SGX PSW, execute the installer with root privilege:

$ cd linux/installer/bin
$ sudo ./sgx_linux_x64_psw_${version}.bin

Note: On Red Hat Enterprise Linux 7.2 and CentOS 7.3, after Intel(R) SGX PSW installation, execute the following command to update the shared library cache additionally:

$ sudo ldconfig

Start or Stop aesmd Service

The Intel(R) SGX PSW installer installs an aesmd service in your machine which is running in a special linux account aesmd.
To stop the service: $ sudo service aesmd stop
To start the service: $ sudo service aesmd start
To restart the service: $ sudo service aesmd restart

Configure the Proxy for aesmd Service

The aesmd service uses HTTP protocol to initialize some services.
If proxy is required for HTTP protocol, you may need manually setup the proxy for aesmd service.
You should manually edit file /etc/aesmd.conf (refer the comment in the file) to set the proxy for aesmd service.
After you configure the proxy, you need to restart the service to enable the proxy.
