An Identity-based Authenticated Key Agreement Sheme for Heterogeneous Sensor Networks

结合身份密码体制,提出了一个基于身份和地理位置信息的异构传感器网络(HSN)节点间的双向认证及密钥协商方案。不同性能节点之间采用不同的协议完成身份认证和密钥建立,充分发挥了高性能节点的能力,降低了低性能节点的能耗。该方案具有完美前向保密性和主密钥前向保密性,具有较好的抗节点伪造、节点复制和女巫攻击能力。分析与仿真表明,该方案具有较好的安全性。

This paper presents a mutual authenticated key agreement scheme for heterogeneous sensor networks（HSN） using identity-based cryptography.In this scheme,different types of sensors execute different protocols to finish identity authentication and establish shared keys according to their capacities,making the resource of power nodes be used effectively and making the energy of less capable sensors be saved in great deal.This scheme provides perfect forward secrecy and master key forward secrecy and can better resist nodes impersonation,nodes replication and sybil attack.The analysis and simulation results show that this scheme has more security properties and lower cost.
