对控制系统中隐蔽传感器攻击的比较

A Comparison of Stealthy Sensor Attacks on Control Systems

University of Texas at Dallas(达拉斯大学);Singapore University of Technology and Design(新加坡科技设计大学)

AI总结:

本文比较了两种隐蔽攻击类型对系统状态的影响,采用卡方检测法分析攻击序列对报警率的约束。

摘要:

随着对控制系统安全性的关注增加,越来越多的攻击影响真实控制系统。最危险的攻击是那些能够逃避检测的。'隐蔽'一词涵盖了攻击者用来避免检测的各种技术。本文展示了如何在两种重要的隐蔽攻击类型下操控系统状态(特别是与攻击相关的可达集)。我们采用卡方故障检测方法,证明该方法对攻击序列施加约束,要么生成无警报(零警报攻击),要么生成与正常操作不可区分的警报率(隐藏攻击)。

英文摘要:

As more attention is paid to security in the context of control systems and as attacks occur to real control systems throughout the world, it has become clear that some of the most nefarious attacks are those that evade detection. The term stealthy has come to encompass a variety of techniques that attackers can employ to avoid detection. Here we show how the states of the system (in particular, the reachable set corresponding to the attack) can be manipulated under two important types of stealthy attacks. We employ the chi-squared fault detection method and demonstrate how this imposes a constraint on the attack sequence either to generate no alarms (zero-alarm attack) or to generate alarms at a rate indistinguishable from normal operation (hidden attack).
