摘　　要：信息物理系统(Cyber Physical System,CPS)作为融合了计算、通信和控制的智能系统,在诸多领域,如智能交通、智能健康等方面发挥着越来越重要的作用。传感器在CPS中扮演着重要角色,但也常成为攻击者的目标。首先,明确了传感器攻击抵御的研究范围,按照攻击发生时间点,将传感器攻击的相关研究分为了攻击防御、攻击抵御和攻击恢复。然后,回顾了常见传感器攻击的类型和影响,包括拒绝服务攻击、重放攻击、欺骗攻击等。接着,总结了基于多源一致性、历史一致性和响应一致性的传感器攻击检测方法。随后,论述了攻击检测后的数据融合方法,包括基于卡尔曼滤波和基于间隔的数据融合方法。最后,探讨了未来可能的研究方向,以进一步加强CPS中传感器攻击的防御能力。Cyber-physical system(CPS),as an intelligent system integrating computation,communication and control,plays an increasingly important role in various fields such as intelligent transportation and healthcare.Sensors play a crucial role in CPS but are also commonly targeted by attackers.Firstly,the scope of research on sensor attack defense is clarified,and the relevant stu-dies on sensor attacks are categorized into attack prevention,defense and recovery according to the timing of attack occurrence.Next,the types and impacts of sensor attacks are reviewed,including DoS attacks,replay attacks and deception attacks.Then,sensor attack detection methods based on multi-source consistency,historical consistency and response consistency are summarized.Subsequently,data fusion methods after attack detection are discussed,including Kalman filter-based and interval-based data fusion methods.Finally,potential future research directions are explored to further enhance the defense capabilities against sensor attacks in CPS.
