摘要
随着信息物理系统在现代工业和制造业中的广泛应用,其安全性逐渐成为关系社会健康发展的重要因素.由于信息物理系统内部物理设备和通信网络的深度融合,网络攻击对系统安全的威胁日益凸显.首先,从攻击者角度总结各类网络攻击的特点,揭示系统在不同攻击下的脆弱性;其次,针对不同网络攻击的特性,从防御者角度对信息物理系统的安全状态估计、攻击检测和安全控制进行介绍,并阐述各防御策略的主要应用场景和优势;最后,对信息物理系统安全性研究面临的主要挑战进行展望.
With the wide application in modern industry and manufacturing,the security of cyber-physical systems has gradually become an important factor to ensure the healthy development of society,and has received extensive attention from scholars.Due to the deep integration of physical devices and communication networks within cyber-physical systems,the threat of network attacks on system security is becoming increasingly prominent.In this paper,we first summarize the characteristics of various network attacks from the attacker’s perspective,and reveal the vulnerability of systems under different attacks.Secondly,in view of the characteristics of different network attacks,the secure state estimation,attack detection and secure control of cyber-physical systems are introduced from the defender’s perspective,and the main application scenarios and advantages of each defense strategy are presented.Finally,the major challenges for the study of cyber-physical system security are proposed.
