基于CPK的融合网络密钥建立与认证

Key establishment and authentication scheme for heterogeneous integrated network based on CPK

针对无线传感器网络(WSN)和Internet融合网络节点异构特性,在介绍CPK算法的基础上,提出了融合网络节点间密钥建立与身份认证方案。考虑不同节点的资源情况,利用计算机终端(PIR节点)集中存储节点公共信息,将传感器节点的签名验证计算转移至PIR完成,减少节点能耗,同时解决节点间基于不同标识的认证问题。结果表明该方案具有计算量小、存储量少、能耗低的特点,能安全有效地实现融合网络节点间双向身份认证。

A key establishment and authentication scheme inspired by Combined Public Key （CPK） algorithm was proposed for the integrated network of Wireless Sensor Network （WSN） and Internet, in allusion to the heterogeneous characteristics of nodes. In this scheme, Public Information Repository （PIR） node of Internet was used to store the public information in consideration of various resource limits. By transferring the computing of signature verification from the sensor nodes to the PIR, it solved the authentication between nodes with different identity, and had advantage of less energy consumption of sensor nodes. Through analysis, the proposed scheme was proved to be efficient in the mutual authentication at a high security level with less computing, smaller storage and lower energy cost.
