摘　　要：为了全面提高电力物联网安全综合防御能力,解决目前电力物联网终端安全防护及终端认证机制的缺失和不足、电力物联网中海量终端安全接入的问题,文章提出一种基于标识密码公钥体制的安全通信协议。该协议以设备指纹和SM9算法为基础,使用终端唯一识别标记代替传统的数字证书完成终端身份认证,并将其应用到电力物联网终端的数据加密传输中,最后对该协议进行安全性分析,并与传统电力通信接入网的安全接入协议进行对比。结果表明,文章所提协议能有效防范各类网络攻击,节省计算和网络资源,有效解决海量电力物联网终端的安全接入问题。In order to comprehensively improve the security comprehensive defense capability of power Internet of Things(IoT)and solve the lack of security protection,terminal authentication mechanism of power IoT terminal,this paper proposed a secure communication protocol based on IBC(Identity-based Cryptography)system based on the fingerprint and SM9 algorithm,the terminal identity authentication was completed by using the terminal unique identification mark instead of the traditional digital certificate.It was applied to the data encryption transmission of the power IoT terminal.Finally,the security analysis of the protocol was carried out,and the comparison was made with the traditional power communication access protocol.The results show that the protocol can effectively prevent various network attacks,save computing and network resources,and effectively solve the security access problems of mass power IoT terminals.
