A Linux-compatible Library OS for Multi-Process Applications
Graphene is a lightweight guest OS, designed to run a single application with minimal host requirements. Graphene can run applications in an isolated environment with benefits comparable to running a complete OS in a virtual machine -- including guest customization, ease of porting to different OSes, and process migration.
Graphene supports native, unmodified Linux applications on any platform. Currently, Graphene runs on Linux and Intel SGX enclaves on Linux platforms.
With Intel SGX support, Graphene can secure a critical application in a hardware-encrypted memory region. Graphene can protect applications from a malicious system stack with minimal porting effort.
Our papers describe the motivation, design choices, and measured performance of Graphene:
Graphene is at a point where it is functionally ready for testing and development, but there are some known security issues that require more attention. The effort to review and harden security of Graphene is ongoing. Our roadmap is to address the remaining production blockers roughly by the fall of 2021. Of course, with additional help from the community, we can meet these milestones sooner!
The most important problems (which include major security issues) are tracked in #1544 (Production blockers). You should read it before installing and using Graphene.
The latest version of Graphene can be cloned from GitHub:
git clone https://github.com/oscarlab/graphene.gitAt this time Graphene is available only as source code. Building instructions are available.
See our quick start guide.
Applications deployed as Docker images may be graphenized via the gsc tool.
For the full documentation of the Graphene, see the Graphene documentation.
