摘要: 在信息物理系统中,不确定性涉及到系统在运行时遇到的各种不可预测因素,其影响系统性能以及可靠性,增加了系统所面临的安全威胁,使系统更易受到攻击。隐蔽攻击能够成功地绕过异常检测器的检测,同时恶意地破坏网络传输的控制输入信号和传感器测量信号,造成系统性能恶化。为防御该类网络攻击,从防守者的角度,利用检测机制和攻击的结构信息,量化了攻击的隐蔽上界,进而,提出了一种基于该上界信息的自适应攻击补偿器,使装备该补偿器的控制器有效减少隐蔽攻击对系统性能的影响。最后,飞行控制系统的仿真结果说明了所提控制策略的有效性。

Abstract: In the cyber-physical system, the uncertainty involves various unpredictable factors that the system encounters during operation. It affects the system performance and reliability, increases security threats faced by the system, and makes the system more vulnerable to attacks. Stealthy attacks can successfully bypass the detection of the anomaly detector, and maliciously destroy the control input signal and the sensor measurement signal transmitted via networks, resulting in the deterioration of the system performance. In order to defend against such cyber attacks, the stealth upper bound of the attacks is quantified by using the detection mechanism and the structural information of the attacks, and then an adaptive attack compensator is proposed, such that the controller equipped with the compensator can effectively re-duce the impact of stealth attacks. Finally, simulation results of the flight control system validate the developed control strategy.

Key words: cyber-physical system, uncertainty, stealthy attacks, adaptive control, flight control system
