摘要:
本文针对布尔控制网络在非周期性拒绝服务 (Denial of Service, DoS) 攻击下的镇定控制问题展开研究. DoS 攻击是一类通过阻断网络节点间信息传输而削弱系统性能的常见网络攻击. 本文研究服从独立同分布过程的非周期性 DoS 攻击. 首先将遭受攻击的布尔控制网络转化为概率布尔网络, 进而得到系统能够全局随机稳定的充分必要条件. 其次, 基于可达集构造方法, 设计了能够保证系统稳定的状态反馈控制器. 最后, 通过仿真实验验证了所提出理论与控制方法的有效性.
Abstract:
This paper studies the stabilization of Boolean control networks (BCNs) under aperiodic DoS attacks. DoS attacks are a common and destructive network attack that weaken the performance of a system by blocking the transmission of information between network nodes. We focus on analyzing aperiodic DoS attacks that obey an independent and identically distributed process. First, for aperiodic DoS attacks following an independent and identically distributed process, we obtain a necessary and sufficient condition for the system stabilization by transforming the attacked BCN into a probabilistic Boolean network. Second, the state feedback control is designed using the reachable set method to ensure the system stabilization. Finally, the effectiveness of the proposed theory and control method is illustrated by a simulation example.
