seL4 is the world's most secure operating-system (OS) kernel. It is a microkernel that does not provide any application-oriented services, these are implemented on top in an OS personality.
One challenge with any new OS is the availability of device drivers, a mechanism for re-using Linux drivers is key to overcoming this challenge.
The project is to enable such re-use by providing a high-performance interface between virtual machines (VMs) on seL4 and the seL4 Device Driver framework (sDDF). This can then used to host Linux drivers in a minimal Linux kernel running inside a VM to provide device access to the sDDF.
The Trustworthy Systems (TS) Group is the pioneer in formal (mathematical) correctness and security proofs of computer systems software. Its formally verified seL4 microkernel, now backed by the seL4 Foundation, is deployed in real-world systems ranging from defence systems via medical devices, autonomous cars to critical infrastructure. The group's vision is to make verified software the standard for security- and safety-critical systems. Core to this a focus on performance as well as making software verification more scalable and less expensive.
