摘要
文章提出了一种使用双线性对和智能卡的远程用户认证方案.在方案中,如果登录请求为有效时,则远程系统接受请求,并允许用户登入系统.该方案利用了椭圆曲线上离散对数的困难性,使得计算成本更低,安全性更高.另外,该方案主要在注册阶段和登录阶段加强了安全性,能够抵御重放攻击、内部攻击、假冒服务器攻击,同时提供了灵活的密码修改方式,并实现了双向认证.
The paper presened a remote user authentication scheme based on bilinear pairings and smart card. In this scheme, the remote system receives user login request and allows login to the remote system if the login request is valid. This scheme uses elliptic curve discrete logarithm problem to lower the computation cost and highten the security. In addition, the scheme enhances the security in registration phase and login phase. The scheme can withstand replay attack, forgery attack and insider attack. The password can be changed by the user at any time. The scheme achieves mutual authentication.
