针对控制系统所面临的信息安全威胁，开展了工业过程控制系统欺骗攻击研究。把欺骗攻击与过程故障都看作引起系统工作状态异常的诱发因素，统一用故障检测的方法加以检测。首先建立了欺骗攻击模型，接着开发了 TE 过程控制器在环模拟系统，在该仿真系统上对三个欺骗攻击场景利用主元分析统计监控算法进行异常检测。结果表明，传统的故障检测算法在欺骗攻击中漏检率和误报率明显增加。

As industrial networks can be exposed to serious cyber threat ,the paper investigates the vulnera‐bilities of industrial control system under deception attack .Firstly ,models for deception attack were proposed . Secondly ,a hardware‐in‐loop control system of TE process was developed .Finally ,the attack with PCA to de‐tect abnormity was studied on three different scenarios .The results have shown that fault detection algorithm possesses poor performance under deception attacks .
