Mystikos is a runtime and a set of tools for running Linux applications in a hardware trusted execution environment (TEE). The current release supports Intel ® SGX while other TEEs may be supported in future releases.
- Enable protection of application code and data while in memory through the use of hardware TEEs. This should be combined with proper key management, attestation and hardware roots of trust, and encryption of data at rest and in transit to protect against other threats which are out of scope for this project.
- Streamline the process of lift-n-shift applications, either native or containerized, into TEEs, with little or no modification.
- Allow users and application developers control over the makeup of the trusted computing base (TCB), ensuring that all components of the execution environment running inside the TEE are open sourced with permissive licenses.
- Simplify re-targeting to other TEE architectures through a plugin architecture.
Mystikos consists of the following components:
- a C-runtime based on musl libc, but is glibc compatible
- a "lib-os like" kernel
- the kernel-target interface (TCALL)
- a command-line interface
- some related utilities
Today, two target implementations are provided:
- The SGX target (based on the Open Enclave SDK)
- The Linux target (for verification on non-SGX platforms)
The minimalist kernel of Mystikos manages essential computing resources inside the TEE, such as CPU/threads, memory, files, networks, etc. It handles most of the syscalls that a normal operating system would handle (with limits). Many syscalls are handled directly by the kernel while others are delegated to the target specified while launching Mystikos.
Some distributions come with the SGX driver already installed; if it is, you don't need to re-install it. You can verify this by running:
dmesg | grep -i sgxIf the output is blank, install the driver manually by downloading it from Intel.
NOTE: The script below may not refer to the latest Intel SGX DCAP driver. Check Intel's SGX Downloads page to see if a more recent SGX DCAP driver exists.

# change this to match the latest version
LATEST='0.2.0'
RELEASE="mystikos-${LATEST}-x86_64"
# this will create the "mystikos" directory within your current working directory
curl -sSL --ssl https://github.com/deislabs/mystikos/releases/download/v${LATEST}/${RELEASE}.tar.gz | tar -xzf -
# you can use mystikos from your home directory, or any path
export PATH="$PATH:$(pwd)/mystikos/bin"
You may also build Mystikos from source. The build process will install the SGX driver and SGX-related packages for you.
NOTE that Mystikos can only be built on Ubuntu 18.04. We are working on bringing Mystikos to Ubuntu 20.04.
Eager to get started with Mystikos? We've prepared a few guides, starting from a simple "hello world" C program and increasing in complexity, including demonstrations of DotNet and Python/NumPy.
Give it a try and let us know what you think!

You can find more sample applications under /samples folder.
Sometimes, you want to take advantage of specific properties of the Trusted Execution Environment, such as attestation. The following example shows how to write a C program which changes its behaviour when it detects that it has been securely launched inside an SGX enclave.
