CPS: Breakthrough: A Meta-Game Theoretic Approach to Cyber-Physical Co Design of Secure and Resilient Control Systems

ABSTRACT

The new challenge of Cyber-Physical Systems (CPSs) comes from the high interdependency between the cyber and physical layers. The interdependency provides opportunities for adversaries to damage the physical parts through cyber attacks. We use a cross-layer design to study the interdependency between the cyber and physical layers of a CPS. We leverage control, game theory, decision theory, and cryptography to protect CPSs from cyber-physical attacks. In the cyber layer, we develop an impact-aware proactive cyber defense. In the physical layer, we use control and game theory to develop a cyber-aware resilient control for the system in a noisy and adversarial environment. We present different applications: UAVs, 3D printers, and train control systems, to illustrate the cross-layer design.
