摘　　要：针对智能变电站计量系统的特点及其存在的安全隐患,从数据加密、安全认证与密钥协商协议设计、访问控制等方面探讨了智能变电站计量系统安全防护技术。该技术已应用于智能变电站计量系统并经过安全性验证,验证结果表明智能变电站计量系统安全防护技术可有效抵抗病毒、DDos、重放等多种攻击,可以高效地实现身份认证及密钥协商,可以在不影响传输数据实时性和可靠性的前提条件下有效拦截非授权设备访问系统,具有较高的推广应用价值。In view of the characteristics and the existed potential safety hazard of the smart substation measuring system,this paper has explored the security protection technology of the smart substation measuring system from the aspects of data encryption,designing of security authentication and key agreement protocol,access control and etc. the above technology has been used in smart substation measuring system and has been verified,and the verified results show that the security protection technology of the smart substation measuring system can effectively against such attacks as viruses,DDos,replay and so on,and can effectively realize the identity authentication and key agreement. It can effectively block the unauthorized device to access to the system under the precondition of not affect the transmission data＇s real-time performance and reliability. So,it has high popularization and application value.
