多服务器环境下动态身份认证密钥协商方案
Dynamic Identity Authentication Key Agreement Scheme under a Multi-server Environment
摘要
Abstract
In order to improve the security of remote users' identity authentication with network to visit from different servers,based on ECC cryptography and the intractability of discrete logarithmic,with the one-way hash function,we propose a dynamic identity authenti-cation key agreement scheme under a multi-server environment combined with the users' identity and password.It takes advantage of hash function to hide the user's password and identity.Message routing is completed through secure channel,consisting of register stage, login stage,authentication key agreement stage and password change stage.User Uisends an anonymous identity to the registry when reg-istering.In logging,the identity of user Uiis dynamic,which realizes the user's strong anonymity.In key agreement,a three-party mutual authenticationis completed among a reliable registry RC,Sjserver and user Ui.The analysis shows that the scheme has such security fea-tures as resisting replay attacks,resisting forgery attack,anti-malicious legal user attacks,three-party authentication proposed,and strong anonymity.关键词
