一种基于身份的智能电网认证模式

摘要

A new concept of mobile user smart grid ( MUSG) is introduced and the mode of consuming electricity in this MUSG application scene is described. Then an identity-based authentication scheme for MUSG is proposed by using the identity-based cryptographic techniques. Analysis shows that using this scheme can effectively solve the problem of mobile user authentication to meet the demands of the real-time and outdoor electricity consumption. It also ensures the system security while reducing the system cost in computation and communication. It contributes to help the smart grid services conversing from fixed users to mobile users since it really reduces the system loads and improves the system efficiency.%提出了一个移动用户智能电网(Mobile User Smart Grid,MUSG)概念,给出了MUSG场景下的用电模式描述,并利用基于身份的密码技术给出了一种基于身份的MUSG认证方案.分析表明,利用该认证方案不仅可以有效解决智能电网中移动用户的认证问题,满足移动用户即时用电和户外用电的需求,并且在保障系统安全性的同时有效降低了系统的计算和通信开销,减轻了系统的负载压力,提高了系统的使用效率.这为智能电网业务由固定用户向移动用户过渡奠定了基础.
