一种基于无线传感器网络的密钥管理方案

A Key Management Scheme for Wireless Sensor Network

本文提出了一种无线传感器网络中的密钥管理方案,该方案支持密钥建立和更新等过程,并采用邻近节点概率否决投票的方法由基站撤消受节点的密钥集。同时,考虑到传感器节点资源有限的特点,方案中相关的协议和算法都比较简单,并完全避开了代价昂贵的公钥运算,从而使得方案的计算、存储和通信开销都比效小,执行效率大大提高。

This paper proposes a key management scheme for wireless sensor network, which supports key establish- ment, re-keying and revocation of the key ring owned by a compromised sensor node via probabilistic negative polling of its neighbors. Furthermore, the related protocols or algorithms are very simple and no expensive public-key opera- tion is required in view of resource-starved sensor nodes, which minimizes the storage, computation, communication overhead and improves the efficiency of our scheme.
