基于电力CPS系统关键节点脆弱性的信息-物理协同攻击路径分析
Analysis of Information-Physical Coordinated Attack Paths Based on Vulnerability of Critical Nodes in Cyber-Physical Power System
摘要
Abstract
[Objective]Traditional power systems have evolved into more efficient and controllable cyber-physical systems(CPS)with the integration of advanced digital information technology and power physical systems.However,this also increases the risk of cyber-physical collaborative attacks.[Methods]This study analyzes the sources of physical system security incidents caused by information system security threats,categorizes the types of cyber-physical collaborative attacks,and establishes two typical attack scenarios.A simplified single-sided network structure of the power CPS was modeled based on complex network theory and energy-information flows.A three-layer cyber-physical power system network node one-to-one dependency framework was built using the correlation matrix theory.The evolution model of cascading failures in cyber-physical power system nodes was proposed,and a weighted comprehensive centrality index was designed to assess the vulnerability of key nodes.[Results]By simulating different cyber-physical collaborative attack strategies,the node survival rate performance under continuous attacks or failures is analyzed.The accuracy of this method in identifying cyber-physical attack paths is validated.[Conclusions]This study provides a technical reference for the security risk analysis of critical nodes and stable operation control in practical power systems.关键词
