Description
Summary:The widespread use of the network in control systems significantly increases the risk of cyber attacks. As a kind of cyber attacks, covert attack has attracted much attention in recent years. In the covert attack, the adversary can control the plant arbitrarily through the communication network without being detected by the monitoring system. This paper is concerned with a new covert attack strategy called robust covert attack on cyber-physical systems. Different from the standard covert attack, the adversary doesn't need to have the complete knowledge of the plant model in the proposed robust covert attack. The robust covert attack is made stealthy in the presence of model uncertainty by using the sliding mode control and time-delayed estimation technique. The stealthiness of the robust covert attack is illustrated by an example.
