一种基于CPK的WSN节点认证和密钥协商方案

认证技术是保护系统资源与用户隐私的一个关键技术,在信息安全领域中有着重要的位置.针对传统的认证方案对节点认证效率低,且不适用于大规模部署的无线传感器网络认证的问题,采用层次化无线传感器网络模型,提出一种基于CPK的双向无线传感器节点认证及密钥协商算法.结果表明,该算法无需安全信道传输消息,能高效地完成节点认证与密钥协商,解决了大规模部署的无线传感器网络认证的问题.

A New Node Authentication and Key Agreement Scheme for WSN Based on CPK

Authentication technology holds an important position in the field of information security,which protects the system resources and users' privacy. In order to solve the disadvantages of traditional authentication scheme,the low efficiency of the node authentication and the unsuitability for large-scale deployment of wireless sensor network certification,a new wireless sensor network node authentication and key agreement scheme is proposed in this paper based on the combined public key,using hierarchical wireless sensor network model. Experimental results show that this technology can better complete the node authentication and key agreement,and solve the large-scale deployment of wireless sensor network authentication problem.
