多服务器环境下基于扩展混沌映射的认证密钥协商协议
Authenticated key agreement protocol based on extended chaotic maps for multi-server environments
摘要
Abstract
In a traditional single server smart card authentication scheme,one server is responsible for providing services to all the registered remote users.If a user wishes to access network services from different servers,he or she has to register with these servers separately.To handle this issue,multi-server authentication scheme has been proposed.However,most of these schemes available in the literature couldn’t achieve strong security.Inspired by the semi-group property of Chebshev maps and key agreement protocols based on extended chaotic maps,this paper proposed an authentication scheme for multiserver envi-ronment that not only resisted various attacks but also achieved strong anonymity for hiding login user’s real identity from other servers.It eliminated the use of verification table and permited the registered users to access multiple servers without separate registration.Compared with other previous related schemes,the proposed scheme keeps the efficiency and security,thus it is more suitable for the practical applications.关键词
