Winwood, Simon; Klein, Gerwin; Sewell, Thomas; Andronick, June; Cock, David; Norrish, Michael


This paper presents the formal Isabelle/HOL framework we use to prove refinement between an executable, monadic specification and the C implementation of the seL4 microkernel. We describe the refinement framework itself, the automated tactics it supports, and the connection to our previous C verification framework. We also report on our experience in applying the framework to seL4. The characteristics of this microkernel verification are the size of the target (8, 700 lines of C code), the...[Show more]
