摘要:

该草案解决了在统一控制和检测框架中检测对自动控制系统的隐形完整性网络攻击的问题。首先介绍了一种无法使用成熟的基于入侵者的技术检测到的一般形式的完整性网络攻击作为内核攻击。著名的重放攻击、零动态攻击和隐蔽攻击是核攻击的特殊形式。给出了核攻击的存在条件。它表明,在控制和检测的统一框架中,所有的内核攻击,可以在结构上检测时,不仅基于控制器的残留,而且基于控制信号的残留信号的产生和用于检测目的。在分析结果的基础上,提出了两种检测核攻击的方案,在不损失控制性能的前提下,实现了可靠的攻击检测。虽然第一种方案类似于公认的移动目标方法和辅助系统辅助检测方案,但第二种检测器是通过反馈控制系统中的控制和监视信号的加密传输来实现的,该反馈控制系统防止对手通过窃听攻击获得系统知识。这两种方案都说明了检测重放,零动态和隐蔽攻击和三坦克控制系统的实验研究的例子。

英文摘要:

This draft addresses issues of detecting stealthy integrity cyber-attacks on automatic control systems in the unified control and detection framework. A general form of integrity cyber-attacks that cannot be detected using the well-established observer-based technique is first introduced as kernel attacks. The well-known replay, zero dynamics and covert attacks are special forms of the kernel attacks. Existence conditions for the kernel attacks are presented. It is demonstrated, in the unified framework of control and detection, that all kernel attacks can be structurally detected when not only the observer-based residual, but also the control signal based residual signals are generated and used for the detection purpose. Based on the analytical results, two schemes for detecting the kernel attacks are then proposed, which allow reliable attack detection without loss of control performance. While the first scheme is similar to the well-established moving target method and auxiliary system aided detection scheme, the second detector is realised with encrypted transmissions of control and monitoring signals in the feedback control system that prevents adversary to gain system knowledge by means of eavesdropping attacks. Both schemes are illustrated by examples of detecting replay, zero dynamics and covert attacks and an experimental study on a three-tank control system.
