摘　　要：为了满足无线传感器网络组通信的安全,提出一种分层分簇的组密钥管理方案。该方案采用分层的体系结构,将组中节点分为管理层和普通层。BS通过构造特殊的组密钥多项式更新普通层组密钥,而管理层则采用二元单向函数进行组密钥的协商。分析表明,该方案很好满足了无线传感器网络中组密钥管理的前向安全性,后向安全性,并且减小了存储开销、计算开销和通信开销。In this paper, a hierarchical clustering-based group key management scheme is proposed in order to satisfy the secure group communication in wireless sensor network. The proposed scheme adopts the hierarchical architecture and divides the nodes in the group into master-node layer and terminal layer. The group key of terminal layer is updated by constructing a special group key polynomial in BS, and the binary one-way function is used by the master-node layer for group key negotiation. Analysis demonstrates that the scheme well satisfies the forward security and backward security of the group key management in WSN, and reduces the storage overhead, computation overhead and communication overhead as well.
