Zhai, Lijing, Vamvoudakis, Kyriakos G., Hugues, Jérôme.  2022.  A Graph-Theoretic Security Index Based on Undetectability for Cyber-Physical Systems. 2022 American Control Conference (ACC). :1479—1484.
In this paper, we investigate the conditions for the existence of dynamically undetectable attacks and perfectly undetectable attacks. Then we provide a quantitative measure on the security for discrete-time linear time-invariant (LTI) systems under both actuator and sensor attacks based on undetectability. Finally, the computation of proposed security index is reduced to a min-cut problem for the structured systems by graph theory. Numerical examples are provided to illustrate the theoretical results.
