混合密钥管理的传感器网络聚类算法设计实现

密钥管理是解决传感器网络安全的关键技术。现有的密钥管理机制，不能很好地优化系统的整体性能，基于连通支配集对传感器网络进行聚类，在簇内实现集中式密钥管理，簇间通过通信主干实现分布式密钥管理，从而构建安全的传感器网络。实验表明，通过混合式的密钥管理，可以有效延长网络生命期。

Design and implementation of clustering algorithm for wireless sensor networks using hybrid key management

In wireless sensor networks,it is necessary to encrypt messages using key management scheme to achieve communication security.The current key management schemes cannot optimize the whole performance of WSNs(Wireless Sensor Networks),so we propose an hybrid key management scheme which uses an clustering algorithm based on Connected Dominating Set to achieve centric key management inter-cluster and distributed key management intra-cluster.The results of experiments verify the effectiveness of proposed algorithms.
