摘要翻译:
本文研究了具有多个传感器的线性动态系统中虚假信息注入的影响。假设系统不怀疑虚假信息的存在,并且攻击者试图最大化虚假信息对Kalman滤波器估计性能的负面影响。对不同条件下的虚假信息攻击进行了数学刻画。对于攻击者,从理论上推导出了使Kalman滤波器估计误差最大化的最优攻击策略的许多闭式结果。结果表明,通过选择最优相关系数和在传感器间进行功率优化分配,敌手可以显著增加Kalman滤波器的估计误差。具体来说,本文以一个目标跟踪系统为例。从敌手的角度出发,给出了不同场景下的最佳攻击策略,包括同时测量位置和速度的单传感器系统和同时测量位置和速度的多传感器系统。在给定注入偏置噪声总功率的条件下,从迹和行列式两个角度求解最优解。数值结果也说明了所提出的攻击策略的有效性。

英文摘要:
In this paper, the impact of false information injection is investigated for linear dynamic systems with multiple sensors. It is assumed that the system is unsuspecting the existence of false information and the adversary is trying to maximize the negative effect of the false information on Kalman filter's estimation performance. The false information attack under different conditions is mathematically characterized. For the adversary, many closed-form results for the optimal attack strategies that maximize Kalman filter's estimation error are theoretically derived. It is shown that by choosing the optimal correlation coefficients among the bias noises and allocating power optimally among sensors, the adversary could significantly increase Kalman filter's estimation errors. To be concrete, a target tracking system is used as an example in the paper. From the adversary's point of view, the best attack strategies are obtained under different scenarios, including a single-sensor system with both position and velocity measurements, and a multi-sensor system with position and velocity measurements. Under a constraint on the total power of the injected bias noises, the optimal solutions are solved from two perspectives: trace and determinant. Numerical results are also provided in order to illustrate the effectiveness of the proposed attack strategies.
