Stabilization of Cyber Physical System with Data Packet Dropout and Replay Attack via Switching System Approach

摘要

Last years, there were various reports on cyber attacks targeting cyber physical systems (CPS), that's push the specialist to strengthen more the security of cyber physical systems. The need of security becomes a priority for people to protect their information from adversary's hands. A replay attack represents one of the famous network attacks and their existence can make huge damage. In this paper we will study the stabilization problem of cyber physical system (CPS) exposed to a replay attack. The study will take into consideration the effect of packet losses. Linear matrix inequality (LMI) formulation is used to give a sufficient condition for stabilization of the system. Finally, the theory is demonstrated by a numerical example.
