Abstract

The vulnerability of cyber-physical systems (CPS) is a growing area of concern, and in the past decade, researchers have proposed a variety of security defenses for these systems. Most of these proposals are heuristic in nature, and while they increase the protection of their target, the security guarantees they provide are unclear. In this talk we discuss two different approaches for modeling the security guarantees of a cyber-physical system against arbitrary false command attacks. The first part of the talk discusses the idea of providing physical protections by saturating actuators, and the second part of the talk discusses how to use barrier certificates to prove safety of a real-world system. Our work is an effort to move forward CPS security research towards precise definitions, precise claims, and provable security.
