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.
The repository provides a reference implementation of a Launch Enclave for 'Flexible Launch Control' under psw/ae/ref_le. The reference LE implemenation can be used as a basis for enforcing different launch control policy by the platform developer or owner. To build and try it by yourself, please refer to the ref_le.md for details.
See License.txt for details.
See CONTRIBUTING.md for details.
Follow the instructions in the linux-sgx-driver project to build and install the Intel(R) SGX driver.
Ensure that you have one of the following required operating systems:
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 7.4:
$ sudo yum groupinstall 'Development Tools'
$ sudo yum install ocaml wget python
On Fedora 27:
$ sudo yum groupinstall 'C Development Tools and Libraries'
$ sudo yum install ocaml ocaml-ocamlbuild redhat-rpm-config openssl-devel wget python
On SUSE Linux Enterprise Server 12:
$ sudo zypper install --type pattern devel_basis
$ sudo zypper install ocaml ocaml-ocamlbuild automake autoconf libtool 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, CentOS 7.4 and Fedora 27:
$ sudo yum install openssl-devel libcurl-devel protobuf-devel
On SUSE Linux Enterprise Server 12:
$ sudo zypper install libopenssl-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
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
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
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
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 7.4 and CentOS 7.4:
$ sudo yum groupinstall 'Development Tools'
$ sudo yum install python
On Fedora 27:
$ sudo yum groupinstall 'C Development Tools and Libraries'
On SUSE Linux Enterprise Server 12:
$ sudo zypper install --type pattern devel_basis
$ sudo zypper install python
To install the Intel(R) SGX SDK, invoke the installer, as follows:
$ cd linux/installer/bin
$ ./sgx_linux_x64_sdk_${version}.bin
NOTE: You need to set up the needed environment variables before compiling your code. To do so, run:
$ source ${sgx-sdk-install-path}/environment
Compile and run each code sample in Simulation mode to make sure the package works well:
$ cd SampleCode/LocalAttestation
$ make SGX_MODE=SIM
$ ./app
Use similar commands for other sample codes.
If you use an Intel SGX hardware enabled machine, you can run the code samples in Hardware mode.
Ensure that you install Intel(R) SGX driver and Intel(R) SGX PSW installer on the machine.
See the earlier topic, Build and Install the Intel(R) SGX Driver, for information on how to install the Intel(R) SGX driver.
See the later topic, Install Intel(R) SGX PSW, for information on how to install the PSW package.
Compile and run each code sample in Hardware mode, Debug build, as follows:
$ cd SampleCode/LocalAttestation
$ make
$ ./app
Use similar commands for other code samples.
Install the library using the following command:
On Ubuntu 16.04:
$ sudo apt-get install libssl-dev libcurl4-openssl-dev libprotobuf-dev
On Red Hat Enterprise Linux 7.4, CentOS 7.4 and Fedora 27:
$ sudo yum install openssl-devel libcurl-devel protobuf-devel
On SUSE Linux Enterprise Server 12:
$ sudo zypper install libopenssl-devel libcurl-devel protobuf-devel
To use Trusted Platform Service functions:
Ensure mei_me
driver is enabled and /dev/mei0
exists.
Download iclsClient and install it using the following commands:
On Ubuntu 16.04:
$ sudo apt-get install alien
$ sudo alien --scripts iclsClient-1.45.449.12-1.x86_64.rpm
$ sudo dpkg -i iclsclient_1.45.449.12-2_amd64.deb

Download source code from dynamic-application-loader-host-interface project. In the source code folder, build and install the JHI
service using the following commands:
On Ubuntu 16.04:
$ 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, CentOS 7.4 and Fedora 27:
$ sudo yum install libuuid-devel libxml2-devel cmake pkgconfig
$ cmake .;make;sudo make install;sudo ldconfig;sudo systemctl enable jhi
On SUSE Linux Enterprise Server 12:
$ sudo zypper install libuuid-devel libxml2-devel cmake pkg-config
$ cmake .;make;sudo make install;sudo ldconfig;sudo systemctl enable jhi
To install the Intel(R) SGX PSW, invoke the installer with root privilege:
$ cd linux/installer/bin
$ sudo ./sgx_linux_x64_psw_${version}.bin
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
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.
