Recent years have witnessed increasing cyber and physical attacks against encrypted cyber‐physical system (CPS) and the ensuing catastrophic consequences. A modified security signaling game (MSSG) model is proposed for capturing attack‐defense interactions and analyzing the cross‐layer security of encrypted CPS. Cyber real‐time performance and physical control performance are both considered in cross‐layer utility function. Theorems concerning the existence of pure‐strategy and mixed‐strategy perfect Bayesian Nash equilibrium (PBNE) are provided, based on which a cross‐layer security design algorithm is proposed for defender's optimal strategy against potential attacks. A numerical case is studied with the effectiveness of our method being proved.
