Cyber-physical systems (CPS) are characterized by tight integration of cyber (computation and communication) components with physical systems. The CPS paradigm is expected to transform critical sectors of society including energy, health care, and transportation. The integration of cyber systems, however, creates new entry points for cyber attacks, which degrade the availability of the physical system, disrupt the communication protocols needed for coordinated control, and compromise the safety and performance of physical components.

Security of CPS poses an inherently multi-disciplinary research challenge. Network and systems security is needed to discover possible cyber vulnerabilities and develop secure protocols. The incentives, capabilities, and goals of adversary must be understood and modeled, through techniques including game theory. The CPS control actions should be robust to the impact of possible attacks and enable recovery of system functionality when attacks do occur.

The proposed workshop will present a holistic view of CPS security, with perspectives on network security, game theory, and control, as well as a view for how these disciplines can be combined to design resilient, safe, and secure CPS. An important topic will be describing the adversary’s actions in the same game- and control-theoretic language as the physical system dynamics, which enables descriptive modeling and effective mitigation of the attack.

Topics Covered:

  • Static and dynamic game theory and applications
  • Game-theoretic approach to robust and resilient control
  • Attacks on cyber-physical systems and adversary modeling
  • Control-theoretic modeling and mitigation of attacks on CPS
  • Composition of attacks and mitigation of composed attacks
