摘　　要：电力系统中集中式的接入认证方式给认证中心带来了巨大的计算和通信压力。利用区块链去中心化的技术,结合电力通信网的特征,提出适用于电力物联网的分布式认证方案,并研制基于区块链的电力泛在业务接入网关。对接入的终端的合法性进行判断,在有线环境和无线环境下进行终端测试,证明该网关可实现配电自动化、新能源等典型泛在电力物联网系统的终端接入认证,具有普适性好、配置方便的特点,可在不影响原有系统拓扑的前提下显著提高终端系统的安全性。In the power system,the centralized access authentication mode has brought great computing and communication pressures to the authentication center.Therefore,based on the decentralized technology of block chain and the characteristics of power communication network,this paper proposes a distributed authentication scheme suitable for the power internet of things and develops the power ubiquitous service access gateway based on the block chain.It carries out terminal tests in wired environment and wireless environment to judge the legitimacy of the access terminal.The results show the gateway can realize the terminal access authentication of the typical ubiquitous power internet of things system,such as distribution automation,new energy and so on.It has the characteristics of good universality and convenient configuration,and can significantly improve the security of the terminal system without affecting the original system topology.
