摘　　要：处于敌对环境的传感器网络极易遭到攻击,且不存在长期可信的节点可以担当组管。提出一种分布式组密钥管理方案,方案基于簇形结构,充分利用簇内通信及簇间通信的局部特性,对组密钥协作更新。当妥协节点总数在门限以内的某簇检测出节点妥协时,该簇的簇头发起更新,并通过簇内协作将该节点撤销;当某簇妥协节点数目在门限以上时,由该簇邻居簇的簇头发起更新,并通过簇间通信将该簇妥协节点撤销。与已有方案相比较,此方案能实时地更新组密钥,有着更好的安全性并具有较小的通信开销。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...
