Recently, studies have revealed new security issues in critical infrastructures, emphasizing the need for verification of security properties. Any mechanism to verify the security of such systems should merge the cyber and physical aspects in a unified way. This paper proposes a novel direction using process algebras to model and verify security properties within a cyber-physical system (CPS). Specifically, we adopt the π-calculus to perform security analysis of a representative CPS, an advanced electric smart grid. We present the verification of an information flow security property, non-deducibility, defined in terms of more discriminating behavioral equivalences available in π-calculus compared to other process algebras.
