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](https://github.com/01org/linux-sgx) project.
|
|
|
|
The [linux-sgx-driver](https://github.com/01org/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](https://github.com/01org/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 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.
