Abstract Cyber physical systems (CPSs) exist in many modern infrastructure systems, such as the future smart grid, smart transportation networks, and public health systems. CPS security is critical for normal operation of our society. The physical layer networks and the cyber layer networks are all complex networks that are interdependent. A mathematical model is given for the interdependent systems during stochastic malicious attacks, which exist in both the physical layer networks and the cyber layer networks. In addition, an adaptive nonlinear controller is given to synchronize interdependent CPSs during malicious stochastic attacks. The controller uses the properties of a Weiner process for the physical layer networks to synchronize the interdependent CPSs. Numerical simulations show the effectiveness of the theoretical results.
