摘要：Linear deception attacks can bypass the chi 2 detector by tampering with data. In this paper, we provide a secure strategy for a cyber physical system (CPS) against such attacks. In response to these attacks in multi-sensor system, we encrypt the innovation sequence by a watermark, so that they can help the chi 2 detector better detect the original undetected linear deception attacks when the attacker does not know the existence of the watermark. Simultaneously, when the attacker has information about the watermark, the estimated performance and control performance will not be reduced by adjusting the parameters of the watermark. Finally, the effectiveness of this defense strategy against deception attacks is verified by a numerical example. (c) 2021 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.
