摘要(Abstract):

随着电网中泛在传感、实时通信和精准控制技术的广泛应用,智能变电站在增强状态感知与业务决策能力的同时,其数据也可能遭到网络攻击入侵而变得不可信,从而对电力系统的安全运行构成严重威胁。从攻击者的角度构建了变电站虚假数据注入攻击的目标与方法,从防御者的角度分析攻击定位、博弈与溯源策略。针对实际变电站的信息网络安全攻防案例表明,所提攻击溯源算法能够有效检测出隐藏的攻击行为,实现变电站网络攻击有效定位溯源。
With the wide application of ubiquitous sensing,real-time communication and precise control technologies in power grids,intelligent substations are enhancing their state sensing and business decision-making capabilities. Meanwhile,the data may be invaded by cyber-attacks and become untrustworthy,thus imperiling the safe operation of power system. This paper constructs the target and method of substation fake data injection attacks(FDIAs)from the attacker's perspective. It analyzes the attack positioning,game and traceability strategy from the defender's perspective. The cyber attack and defense cases for the substation information network show that the proposed attack tracing algorithm can effectively detect the hidden attack behavior and localize and trace cyber attacks on substations.
