| 摘 要： | 随着无线传感器网络的快速发展,对外部用户的身份进行确认已成为获取传感器网络中实时数据所要解决的关键问题。基于Nam提出的首个广泛适用于面向无线传感器网络的双因素认证方案的安全模型,设计了一个新的可证安全的用户认证密钥协商方案。该方案基于椭圆曲线密码体制,达到用户、网关节点及传感器节点之间的双向认证,满足匿名性并建立会话密钥,最后基于ECCDH困难性假设证明了新方案的安全性。与Nam提出的方案相比,在满足安全性的同时,将参与者的计算效率达到最优,更符合资源受限环境及现实应用。

| Abstract: | With the development of Wireless Sensor Network (WSN), user authentication in WSN is a critical security issue due to their unattended and hostile deployment in the field. To improve the security of user authentication, a new provably-secure two-factor authentication key exchange scheme based on Nam's first security model was proposed. The proposed scheme was based on elliptic curve cryptography, and it achieved authentication security and user anonymity. The safety of the improved protocol was proved based on ECCDH in the random oracle model. Performance analysis demonstrates that compared to Nam's schemes, the proposal is more efficient, and it is more suited to wireless sensor networks environments. |
