多服务器环境下基于椭圆曲线密码的认证协议OACSTPCD
AN ELLIPTIC CURVE CRYPTOGRAPHY BASED AUTHENTICATION SCHEME FOR MULTI-SERVER ENVIRONMENT
本文研究了多服务器环境下的认证密钥协商协议.通过对Andola等人方案的分析,利用椭圆曲线密码和随机数设计了一种改进的认证密钥协商协议.使用BAN逻辑和非形式化分析方法,对协议进行安全性分析.实验结果表明,所提协议具有更好的安全性和实用性.
In this paper,we study the authentication and key agreement protocol for multi-server environment.Through the analysis of the scheme of Andola et al,an improved authentication and key agreement protocol is proposed by using the elliptic curve cryptography and random number.Besides,the security of the improved scheme is proved by BAN logic and the informal security analysis.Experimental results show that the proposed protocol has better security and practicability.
