论文摘要
这项工作对通过事件触发的控制协议对网络物理攻击对多代理共识的性能的不利影响进行了严格分析。它显示了对传感器和执行器的战略恶意攻击如何欺骗基于州的事件触发机制和基于状态的事件触发机制的触发条件，这些机制是常见的，并且在文献中广泛使用。更准确地说，首先表明，在基于结合状态的事件触发机制的情况下，欺骗攻击可能导致非触发不当行为，从某种意义上说，妥协的代理不会触发任何事件，因此会导致部分反馈通过防止信息到达当地邻近的构成代理人的邻居而导致部分反馈。这表明，攻击者可以利用基于状态的事件触发的机制来利用攻击者来损害网络连通性，从而使代理无法使用的最新数据。然后表明，在基于状态的事件触发机制的情况下，欺骗攻击可能导致连续触发的不当行为，因为事件触发的机制连续生成触发事件，从而导致不良的ZENO行为现象。最后，提出数值模拟以说明理论发现。
This work presents a rigorous analysis of the adverse effects of cyber-physical attacks on the performance of multi-agent consensus with event-triggered control protocols. It is shown how a strategic malicious attack on sensors and actuators can deceive the triggering condition of both state-based event-triggered mechanism and combinational state-based event-triggered mechanism, which are commonplace and widely used in the literature. More precisely, it is first shown that a deception attack in the case of combinational state-based event-triggered mechanism can result in a non-triggering misbehavior, in the sense that the compromised agent does not trigger any event and consequently results in partial feedback disconnectivity by preventing information from reaching the local neighbors of the compromised agent. This indicates that the combinational state-based event-triggered mechanism can be leveraged by the attacker to harm the network connectivity by rendering the recent data unavailable to agents. It is then shown that the deception attack in the case of state-based event-triggered mechanism can result in a continuous-triggering misbehavior in the sense that the event-triggered mechanism continuously generates triggering events resulting in undesirable phenomenon of Zeno behavior. Finally, numerical simulations are presented to illustrate the theoretical findings.
