摘要
变电站信息安全体系要应对欺骗、重放、篡改等安全威胁,并且需要具备一定的拒绝服务攻击能力。依据电力系统数据与通信安全标准IEC 62351,讨论基于身份的密码体制在智能变电站中的应用,详细介绍在智能变电站层、间隔层和过程层之间实现安全通信的方法,结合变电站的实际情况,讨论了基于身份的密码体制的实现方法和步骤以及应用实例。研究结果对在智能变电站自动化系统中实施IEC 62351标准具有重要的参考意义。
Smart substations information security system needs to deal with deceit, replay, tampering and other security threats, and it requires a certain ability to deal with denial of service attack. In accordance with pow- er system data and communication safety standard IEC 62351, the paper discusses the application of identity- based cryptosystem and elaborates on the way of safe communication among smart substation layer, interval layer and process layer. By combining practical situation of substations, the paper expounds the implementa- tion method, procedure and application examples of identify-based cryptosystem. The research result can pro vide importance reference for implementation of IEC 62351 standard in automation system of smart substations.
