摘　　要：电力广域测量系统作为智能电网监测的重要部分,其安全至关重要。因此,为了保证电力广域测量系统中通信数据的完整性和机密性以及系统内部各个终端设备之间的通信安全,提出一种基于SM2算法的电力广域测量系统安全认证方案。该方案基于SM2算法以及数字证书技术实现相互认证,提高智能电网设备中PMU设备之间的数据通信安全性和可靠性。最后,通过安全分析和实验评估表明,该方案能够有效抵御中间人攻击、重放攻击、长时间窃听等多种攻击。As an important part of smart grid monitoring system,the security of power wide area measurement system is very important.Therefore,in order to ensure the integrity and confidentiality of communication data in power wide area measurement system and the communication security between terminal devices in the system,a security authentication scheme of power wide area measurement system based on SM2 algorithm was proposed.Mutual authentication based on SM2 algorithm and digital certificate technology was realized by the scheme,which also improves the security and reliability of data communication between PMU devices in smart grid devices.Finally,the security analysis and experimental evaluation show that man in the middle attack,replay attack,longtime eavesdropping and other attacks can be resisted effectively by the scheme.
