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

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

Build and Install the Intel(R) SGX Driver

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

Note: SGX 2.0 feature support in the SDK and PSW depends on processor and driver support for the SGX 2.0 instruction set. Please consult the README in the driver for instructions on building the SGX 2.0 Linux Driver. Upcoming CPU releases will include hardware support for SGX 2.0.

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

Prerequisites:

Ensure that you have one of the following required operating systems:
- Ubuntu* Desktop-16.04-LTS 64bits
- Red Hat Enterprise Linux Server release 7.4 64bits
- CentOS 7.3.1611 64bits

Use the following command(s) to install the required tools to build the 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 7.4 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 the 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 7.4 and CentOS 7.3:
```
$ sudo yum install openssl-devel libcurl-devel protobuf-devel
```
Use the script download_prebuilt.sh inside source code package to download prebuilt binaries to prebuilt folder
You may need set an https proxy for the 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(R) SGX SDK and PSW. You can build the project according to your requirements.

To build both Intel(R) SGX SDK and PSW with default configuration, enter the following command:
```
$ make  
```
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(R) SGX SDK component only. However, building the PSW component is dependent on the result of building the Intel(R) SGX SDK.
This repository supports to build the Intel(R) SGX SDK based on either precompiled optimized IPP/string/math libraries or open sourced version of SGXSSL/string/math libraries. The default build uses precompiled optimized libraries, which are downloaded by the script ./download_prebuilt.sh. You can also use the open sourced version implementation instead by entering the following command:
```
$ make USE_OPT_LIBS=0
```
Note: Building the Intel(R) SGX PSW with open sourced SGXSSL/string/math libraries is not supported. The above command builds Intel(R) SGX SDK only and the build of PSW part will be skipped.
To build Intel(R) 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(R) 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 the Intel(R) SGX SDK Installer

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

$ make sdk_install_pkg

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

Note: The above command builds the Intel(R) SGX SDK with default configuration firstly and then generates the target SDK Installer. To build the Intel(R) SGX SDK Installer with debug information kept in the tools and libraries, enter the following command:

$ make sdk_install_pkg DEBUG=1

Build the Intel(R) SGX PSW Installer

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

$ make psw_install_pkg

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

Note: The above command builds the Intel(R) SGX SDK and PSW with default configuration firstly and then generates the target PSW Installer. To build the Intel(R) SGX PSW Installer with debug information kept in the tools and libraries, enter the following command:

$ make psw_install_pkg DEBUG=1

Install the Intel(R) SGX SDK

$ sudo apt-get install uuid-dev libxml2-dev cmake pkg-config
$ cmake .;make;sudo make install;sudo systemctl enable jhi

On Red Hat Enterprise Linux 7.4 and CentOS 7.3:

$ sudo yum install libuuid-devel libxml2-devel cmake pkgconfig
$ cmake .;make;sudo make install;sudo ldconfig;sudo systemctl enable jhi

Install the Intel(R) SGX PSW

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

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

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