Abstract

This paper proposes a consensus secure control scheme in the presence of denial-of-service (DoS) attacks based on an event-trigger mechanism. In contrast to a scenario in which attacks are the same and simultaneously paralyze all channels, the DoS attack addressed in this paper occurs aperiodically and results in the independent interruption of multiple transmission channels. A sufficient condition for the attack duration is designed and a distributed event-triggered control scheme is proposed, where the updated instants are triggered aperiodically to reduce the required communication resources. It is shown that the overall system is stable with the proposed scheme according to the Lyapunov stability theory and that Zeno behavior is excluded. Finally, a numerical example is presented to verify the effectiveness of the proposed scheme.

在多个传输通道上受到DoS攻击的基于线性事件的基于事件触发的共识安全控制

摘要

本文提出了一种基于事件触发机制的拒绝服务（DoS）攻击存在的共识安全控制方案。与攻击相同且同时使所有通道瘫痪的情况相反，本文中解决的DoS攻击是不定期发生的，并导致多个传输通道的独立中断。设计了攻击持续时间的充分条件，并提出了分布式事件触发控制方案，其中不定期地触发更新的时刻以减少所需的通信资源。结果表明，根据李雅普诺夫稳定性理论，采用所提出的方案，整个系统是稳定的，并且排除了芝诺行为。最后，通过数值例子验证了所提方案的有效性。
