基于多阶段博弈的电力CPS虚假数据注入攻击防御方法

A Multi-Stage Game Based Defense Method against False Data Injection Attack on Cyber Physical Power System

信息通信技术的快速发展使电力系统成为典型的信息物理系统(cyber physical system, CPS)。在电网侧控制日趋智能化的同时,电力CPS也面临潜在的网络攻击风险。文章首先分析了针对电力CPS的虚假数据注入攻击(false data injection attack,FDIA)的可行性,然后针对攻击方和防御方的多阶段动态交互过程,提出了一种基于博弈论的关键测量设备的分阶段动态防御方法,通过IEEE标准系统算例验证了所提方法的可行性和有效性。

With the great development of the information communication technology,power systems have been typical cyber physical system(CPS).Although the control function of the grid side is becoming more intelligent,cyber physical power system(CPPS)brings the risk of potential cyber attacks.In this paper,the feasibility of false data injection attack(FDIA)for CPPS is analyzed firstly,then a defense method for key measurement devices is proposed on the basis of game theory for the multi-stage dynamic interaction process between attacker and defender.The feasibility and effectiveness of the proposed method are verified on the IEEE standard system.
