Trustworthy Systems

Welcome to Trustworthy Systems!

(Most of) Trustworthy Systems in December 2021.

We are the Trustworthy Systems Group

We research techniques for the design, implementation and verification of secure and performant real-world computer systems.

We achieve impact by fundamentally changing how software systems are engineered in the real world. Our techniques provide the highest possible degree of assurance—the certainty of mathematical proof—while being cost-competitive with traditional low- to medium-assurance systems.

Our research brings together a unique combination of expertise in operating systems, formal methods and programming languages. Our seL4 microkernel is the most thoroughly verified operating system kernel in the world.

Our work goes beyond research. We show how to build robust, high-performance software stacks for the software development community, and also engage with other organisations to apply our technology to real problems.
