Distributed group key management scheme based on cluster collaboration in WSN
无线传感器网络中基于簇协作的分布式组密钥管理方案

Sensor network is vulnerable to attacks when deployed in unattended fields,and no node can be trusted all the time thus can act as a key server.In this paper,a distributed group key management scheme was proposed.In the new scheme,the group rekeying process took full advantage of the characteristics of the inter-cluster and intra-cluster communication.When the number of the compromised nodes inside one cluster was smaller than t and a compromised node inside the cluster was detected,the group rekeying would...
