VS2W01 - Vistas in Verified Software

SCION is a new Internet architecture that addresses many of the security vulnerabilities of today’s Internet. Its clean-slate design provides, among other properties, route control, failure isolation, and multi-path communication. The verifiedSCION project is an effort to formally verify the correctness and security of SCION . It aims to provide strong guarantees for the entire architecture, from the protocol design to its concrete implementation. The project uses stepwise refinement to prove that the protocol withstands increasingly strong attackers. The refinement proofs assume that all network components such as routers satisfy their specifications. This property is then verified separately using deductive program verification in separation logic. This talk will give an overview of the verifiedSCION project and explain, in particular, how we verify code-level properties such as memory safety, I/O behavior, and information flow security.
