基于节点间信任评估算法的无线传感器网络密钥管理方案

Key Management Scheme of Wireless Sensor Network Based on Trust Evaluation Algorithm between Nodes

提出了一种基于信任机制的密钥管理方案,通过评测发起节点的信任值,判断节点是否可以作为密钥更新的簇头节点。方案中采用了双向信任数据包转发机制,不仅可以获取节点的信任值,同时也验证信任数据包的正确性,进一步提高了密钥管理实施过程中的安全性。同时对所阐述的方案,从安全性、通信复杂度和存储消耗等方面进行了理论研究和分析,并进行了实验仿真,具有较高的安全性。

This paper presented a key management scheme based on trust mechanism.Through evaluating the trust value of the originating node,it determines whether the node can be the head node of a cluster for key updating.This scenario with a two-way trust packet forwarding mechanism,can not only get the trust value of the node,but also verify the correctness of the trust packet.It further improves the security of the key management implementation process.Meanwhile,this paper did theoretical research and analysis from the aspect of security,communication complexity and memory consumption,and experimental simulation.
