Abstract
This paper concentrates on security estimation of Cyber-Physical Systems subject to Denial-of-Service attack. A game framework is established to describe the interactive decision making process between the sensor and the attacker under energy constraint. A novel payoff function is used and the optimal strategies for both sides constituting a Nash equilibrium (NE) are obtained by using matrix game. Furthermore, the security issue on state estimation for CPS with multiple-subsystem is investigated based on game theory. To deteriorate the whole system performance, the attacker should decide when to attack and which subsystem to be chosen on account of limited energy. The existence conditions of NE strategies are given. Two numerical examples are provided to demonstrate the feasibility of the results.
CONCLUSION
In this paper, the problem of remote state estimation under DoS attack has been studied. Firstly, a system where one sensor communicated with a remote estimator through a wireless channel was considered. The DoS attacker can jam the transmission channel with limited actions in any time. A novel game framework was proposed and the optimal strategies for both sides have been obtained by using matrix game. Further, we extended it to the scenario with multiple-subsystem. An integrated game-theoretic framework was developed to investigate the interactive decision-making process between the sensors and the attacker. Moreover, existence conditions of NE strategies were presented. Simulation examples demonstrate the effectiveness of the provided techniques.
