摘　　要：对智能变电站通信安全技术进行研究。针对智能变电站面向通用对象的变电站事件信息在站控层及过程层传输过程中存在的网络攻击风险,引入一种利用密码学散列函数进行消息认证的哈希消息身份验证码进行加密,确保智能变电站信息传输的安全性与高效性。提出哈希消息身份验证码加密方式,将密钥和密码学散列函数相结合,用于数据验证。搭建基于IEC 62351的面向通用对象的变电站事件信息的传输支架平台,测试不同哈希函数算法、不同长度密钥、不同长度面向通用对象的变电站事件信息时的消息延迟时间。研究结果表明,哈希消息身份验证码可以确保智能变电站网络具有安全性和高效性,在一定程度上可以降低智能变电站的网络安全风险,保障电网安全稳定运行。The communication security technology for intelligent substation was studied.Aiming at the network attack risk in the transmission process of GOOSE message in the station control layer and process layer in intelligent substation,a hash message authentication code using cryptographic hash function for message authentication was introduced for encryption to ensure the security and efficiency of information transmission in intelligent substation.The hash message authentication code encryption method that combines the key with cryptographic hash function was proposed for data verification.A transmission support platform for GOOSE message based on IEC 62351 was built,and the message delay time was tested with different hash function algorithms,different length keys,and different length GOOSE messages.The research result indicates that the hash message authentication code can ensure the security and efficiency of intelligent substation network,reduce network security risk of intelligent substation network to a certain extent,and ensure the safe and stable operation of power grid.
