摘要：AbstractAs networks become more widely used in control systems, the risk of cyber attacks increases significantly. The risk arising from stealthy attacks is that an adversary may take control of the plant through the communication network without being detected by the usual monitoring systems, with consequences that are often malicious or even destructive. This paper considers a new attack scheme called robust stealthy covert attack. Unlike the standard covert attack in Smith (2011), the robust covert attack can keep its stealthiness, even if the adversary doesn't have complete knowledge of plant model. It will be shown that the robust covert attack can be made stealthy by applying the time delayed control technique. An example is given to illustrate the stealthiness of the proposed robust covert attack in the presence of modeluncertainties.
