针对电力二次系统安全防护体系中缺乏基于国产安全加密算法体制的现状,提出在电力二次保护设备嵌入式系统中运用 SM2数字签名算法的方案。SM2算法主要以模运算、点加、倍点和标量乘运算为基础实现,在电力分界开关控制器通信之前,实现双方系统身份认证。算例测试结果表明,SM2数字签名算法能够提供安全的身份认证,可有效实现用户身份真伪性的辨别。

In order to solve the absence of safety protection based on domestic security encryption algorithm systems in electric power secondary systems,a scheme,which applied the SM2 digital signature algorithm on the embedded systems of power secondary protection equipments,has been proposed in this paper.SM2 digital signature algorithm is based on modular operation,point addition,multiple points and scalar multiplication operation.Before mutual-communication,both side can realize identity authentication.The testing results show that SM2 digital signature algo-rithm can provide secure identity authentication and discriminate the users’identity authenticity.
