Abstract

Malicious attacks on Cyber-Physical Systems (CPS) may cause significant damage to the targeted system. In this thesis, we address the problem of attack detection as well as attack correction for multi-input multi-output discrete-time linear time-invariant dynamical systems when the attacker can inject signals (additively) to sensors and actuator signals. We consider the cases of sensor only attacks, actuator only attacks and consider the case when both sensors and actuators are attacked. We also consider the case when we have prior knowledge about a specific subset of sensors and/or actuators that is not accessible by the attacker. For each attack scenario (sensor and/or actuator attacks wit..
