This paper is concerned with the security control problem for a class of networked systems subject to deception attacks and packet dropouts. First, by taking into account the deception attacks and packet dropouts in an unified framework, a discrete-time stochastic system is presented. In virtue of matrix exponential computation, an equivalent discrete-time stochastic model is established. Based on this, the security analysis is given by the law of total expectation and some sufficient conditions are provided. Subsequently, a controller is designed. Finally, the effectiveness of the proposed method is illustrated by two examples including a practical power grid system.

本文关注的是一类遭受欺骗攻击和数据包丢失的网络系统的安全控制问题。首先，通过在统一框架中考虑欺骗攻击和数据包丢失，提出了一个离散时间随机系统。借助矩阵指数计算，建立了等效的离散时间随机模型。在此基础上，由总期望定律给出了安全性分析，并给出了一些充分条件。随后，设计了一个控制器。最后，通过包括实际电网系统在内的两个例子说明了所提出方法的有效性。
