摘要
介绍了几种身份隐私保护技术,提出了基于中国剩余定理的智能电表身份认证方案,使得智能电表的真实身份得到了有效保护,在有效抵御外部攻击者的同时,使内部参与者也不能获得用户的真实身份和实时电量.与现存的几种技术相比,本方案计算成本较低,且可以有效支持电力用户数量的动态变化,满足电力用户身份认证条件的动态更新.
Some techniques for protecting identity authentication are introduced. A smart meter identity authentication scheme based on Chinese Residual Theorem is proposed so that the true i- dentity of smart meters is effectively protected against external attackers and at the same time, in- ternal participants can not get the user＇s true identity and real-time power. Compared with several existing research schemes, the proposed scheme not only lows computational cost, but also can effectively support the dynamic change of the number of power users, and effectively meet the dynamic updating of the power user authentication conditions.
