摘要:

本文从博弈论角度研究动态多传感器系统中虚假信息注入攻击与防御问题。将卡尔曼滤波与攻击者的关系视为两人零和博弈。本文探讨在何种条件下双方都能达到纳什均衡。假设多传感器卡尔曼滤波系统和攻击者都是理性玩家。卡尔曼滤波和攻击者必须选择各自传感器子集进行系统状态估计和虚假信息注入。展示了双方如何选择策略以获得更多收益并减少损失。通过求解极小极大问题得到最优解。还提供了数值结果以说明所推导的最优策略的有效性。

英文摘要:

In this paper, the problem of false information injection attack and defense on state estimation in dynamic multi-sensor systems is investigated from a game theoretic perspective. The relationship between the Kalman filter and the adversary can be regarded as a two-person zero-sum game. Under which condition both sides of the game will reach the Nash equilibrium is investigated in the paper. The multi-sensor Kalman filter system and the adversary are supposed to be rational players. The Kalman filter and the adversary have to choose their respective subsets of sensors to perform system state estimation and false information injection. It is shown how both sides pick their strategies in order to gain more and lose less. The optimal solutions are achieved by solving the minimax problem. Numerical results are also provided in order to illustrate the effectiveness of the derived optimal strategies.
