一种动态分簇无线传感器网络密钥管理方案

层簇式无线传感器网络因管理方便、能量利用率高等优点,是近年来研究的热点,目前已提出了很多基于簇的路由协议,但这些协议很少考虑到安全性问题,而针对这种分簇式网络结构提出的密钥管理方案又都存在一些不足,不能很好地与路由协议结合使用。针对这些问题,提出了一种轻量级的密钥管理方案KMDC(Key Management for Dynamically Clustering WSN),分析表明该方案可以有效地解决密钥管理的问题。

Key management scheme for dynamically clustering wireless sensor networks: KMDC

Because of the convenience in management and efficiency in energy,cluster-based wireless sensor networks are becoming more and more important.Many routing protocol have been proposed for them.But most of them pay no attention to the security problems,and key management schemes for them have also defects.So we proposed a lightweight key management to resolve these problems.
