Abstract

Cyber-physical system security must consider events in both the cyber and physical layers. This paper proves that a cyber process in the smart grid can lie about its physical behavior and remain undetected by its peers. To avoid this scenario, physical attestation is introduced as a distributed mechanism to validate the behavior of a cyber process using physical measurements. A physical attestation protocol is developed for the smart grid, and the protocol is proven to expose malicious cyber behavior. Through the use of physical attestation, the behavior of cyber processes in cyber-physical systems can be verified.
