摘要
随着IEC6150标准智能变电站和智能电网的广泛应用,变电站站内二次系统通信安全成为不容忽视的问题。结合IEC62351标准,以变电站站内为整体,从身份认证、加密通信、防重放攻击、密钥分配等方面研究变电站通信规约MMS、GOOSE/SMV的安全增强技术,并探讨加密后报文的分析技术,采用开源软件针对嵌入式系统定制改造,并结合试点装置运行情况,分析规约安全增强的设备通信性能。
With the wide application of smart substation communication protocol IEC6150 and Smart Grid,IEC61850 safety issue has become a problem can't be ignored. Combined with IEC62351, in the internal of substation as a whole, from authentication, encrypted communications, anti-replay attack, key distribution, the communication protocol security enhancement with in side of the substation which included MMS, GOOSE and SMV protocol was studied. Encrypted packet analysis technology was discussed. Combined with the test equipment run conditions, the performance caused by protocol security enhancement equipment was analyzed.
