Welcome to Trustworthy Systems!
We are the Trustworthy Systems Group
We research techniques for the design, implementation and verification of secure and performant real-world computer systems.
- We aim to change the world by making software truly trustworthy.
- Having made verified software a reality, our goal is to create a societal shift towards mainstream adoption.
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.
