The sel4 verification: the art and craft of proof and the reality of commercial support (invited talk)

ABSTRACTThe formal verification of the seL4 microkernel started as a research project in 2004 and has achieved commercial scale now, in the number of properties proven, the supported features and platforms, the adoption and deployment by industry and government organisations. It is supported by an open-source Foundation and a growing ecosystem. In this talk, I will reflect on the seL4 verification journey, past, present and future, and the challenges to combine the art and craft of proof with the reality of meeting industry demand for verified software.
