Introduction to the seL4 proofs
This screencast gives a guided tour of the Isabelle/HOL proofs about the seL4 microkernel, focussing mainly on the abstract specification and some of the properties we prove about it. It was given as a pre-recorded talk for the third seL4 Summit, held virtually in November 2020. The talk assumes some familiarity with seL4, but aims to be accessible to people without previous experience of formal software verification or interactive theorem proving.
Also on YouTube. MP4 downloads are available from Vimeo. There are slides, and a rough transcript.
