论文摘要
动态水印方案可以增强网络控制系统（NCSS）的网络攻击检测能力。本文提出了一种线性事件触发的解决方案，用于传统的动态水印（CDW）方案。首先，研究了基于事件触发状态估计的NCSS的CDW方案的局限性。其次，新的事件触发的动态水印（ETDW）方案是通过将水印作为对称密钥加密而设计的，它基于概率的极限收敛定理。还以有限的渐近攻击力的形式讨论了针对广义重播攻击（GRA）的安全性。第三，有限的样品ETDW测试是针对基质浓度不等式设计的。最后，网络倒置系统的实验结果证明了我们提出的方案的有效性。
Dynamic watermarking schemes can enhance the cyber attack detection capability of networked control systems (NCSs). This paper presents a linear event-triggered solution to conventional dynamic watermarking (CDW) schemes. Firstly, the limitations of CDW schemes for event-triggered state estimation based NCSs are investigated. Secondly, a new event-triggered dynamic watermarking (ETDW) scheme is designed by treating watermarking as symmetric key encryption, based on the limit convergence theorem in probability. Its security property against the generalized replay attacks (GRAs) is also discussed in the form of bounded asymptotic attack power. Thirdly, finite sample ETDW tests are designed with matrix concentration inequalities. Finally, experimental results of a networked inverted pendulum system demonstrate the validity of our proposed scheme.
