Stealthy Targeted Local Covert Attacks on Cyber-Physical Systems

Cyber security is nowadays an important research area in cyber-physical systems (CPS) to prevent possible disastrous physical consequences. In this paper, we consider stealthy targeted local covert attacks, which take into account the target of the adversary explicitly and need fewer disruption resources than standard covert attacks. We show conditions when the local attack can achieve its target and simultaneously remain stealthy. The provided conditions help to analyze the CPS on potential fraud and enhance the cyber security. Experimental results on the three-tank system are provided to illustrate the main results.
