面向源网荷储的多实体身份可信认证机制研究

A Trusted Authentication Mechanism Research for Multi Entity Identity TowardsSource-grid-load-storage

新型电力系统下,源网荷储业务中接入大规模海量设备,多部门主体间业务频繁交互,面临身份认证效率较低及隐私泄露等问题。文章综合考虑源网荷储多实体身份认证需求,提出了一种多实体身份可信认证机制,构建了基于联盟链的多主体实体身份可信认证系统。该系统应用改进的RAFT共识算法、智能合约以及零知识证明等技术,有效提高了源网荷储认证效率,实现了多实体间安全互联及敏感信息隐私保护。文章模拟了一个源网荷储场景,测试了该方案的性能,证明了该方案的可行性。

Under the new type of power system,large scale and massive equipment are connected to the source-grid-load-storage business.As well as,among the multiple departmental entities,the interactions happened frequently,which followed with low authentication efficiency and privacy breaches problems.This paper comprehensively considers the demand for trusted authentication of source-grid-load-storage identity,proposes a multi entity trusted authentication mechanism,and constructs a multi-agent entity trusted authentication system based on alliance chain.The system applies improved RAFT consensus algorithm,smart contract and zero-knowledge proof technologies to improve the efficiency of source-grid-load-storage authentication effectively,and to achieve secure interconnection between multiple entities,and to protect the sensitive information privacy.Further,a scenario of source-grid-load-storage is simulated to test the performance of the scheme and prove its feasibility.
