摘要: 安全问题是无线传感器网络应用的关键性问题,而密钥管理是安全问题的核心。由于传感器网络的Ad-hoc属性以及资源限制,提供一种正确的密钥管理方案成为一项具有挑战性的工作。对原三密钥管理机制在层次结构上进行了一些简化,而在路由方面提出了进一步的算法,提高了无线传感器网络对外部攻击的抵抗性,并可支持更大规模的网络,同时节点内存负载变化不大,适用于对安全性要求较高的无线传感器网络应用。

Abstract: Security issue is crucial to the application of wireless sensor network(WSN),and key management is the kernel of security issues.A new secure triple-key management scheme is presented,which optimizes the procedure of keys computation,and improves the secure routing algorithm.Consequently the ability of resilience against attacks is increased,the greater scalability is supported,and the storage overheads of network are decreased a little.This scheme is adapted to application of wireless sensor network which requires high security performance.
