一种抗单点失效的认证方案

An Authentication Scheme Against Single Point Failure

针对现有的手持移动终端与服务器认证过程中存在服务器被攻击,致使非法终端通过认证,造成整个系统的数据与功能等资源遭到破坏的情况,提出了一种新的认证方案,有效地解决单个服务器受攻击后出现的伪认证问题。提出的认证方案采用双线性对、秘密共享方法实现了门限认证,通过安全性分析、性能实验对比,证明该认证方案有较强的安全性及较高的计算效率。

In the existing hand-held mobile terminal and server authentication process exists in the case of server attacks,which causes the illegal terminal to pass the authentication and results in the destruction of the data and functions of the whole system,this paper presents a new authentication scheme,and effectively solves the problem of false certification after the attack of a single server. In this paper,we propose a new authentication scheme using bilinear pairing secret sharing method to achieve threshold authentication,and through the safety analysis and the performance experiment contrast,it is proved that authentication scheme proposed in this paper has stronger security and higher computing efficiency.
