基于智能卡和密码保护的WSN远程用户安全认证方案

针对无线传感器网络（WSN）用户远程安全认证问题，分析现有方案的不足，提出一种新颖的基于智能卡的WSN远程用户认证方案。通过用户、网关节点和传感器节点之间的相互认证来验证用户和节点的合法性，并结合动态身份标识来抵抗假冒攻击、智能卡被盗攻击、服务拒绝攻击、字典攻击和重放攻击。同时对用户信息进行匿名保护，且用户能够任意修改密码。性能比较结果表明，该方案具有较高的安全性能，且具有较小的计算开销。

A Remote User Security Authentication Scheme Using Smart Card and Password Protection for WSN

For the issues that the user remote security authentication for wireless sensor network（WSN）, and the defects of the existing schemes, a remote user security authentication scheme of using smart card for WSN was proposed. The mutual authentication between the user, the gateway nodes and sensor nodes was used to verify the legitimacy of users and nodes. This scheme combines mutual authentication and dynamic identity to resist the impersonation attack, smart card stolen attack, distributed denial of service attack, dictionary attack and replay attack. At the same time, the user information was provided anonymous protection, and the user could change the password. The performance comparison results show that the proposed scheme has high security performance and small computational cost.
