摘　　要：在现有基于密钥树的密钥预分配协议的基础上,结合传感器节点的路由拓扑,根据不同节点的通信要求,提出一种适用于分簇网络的两级密钥管理方案,簇间采用逐级加密和认证机制,簇内指定一个管理节点负责生成和维护全簇的路由密钥树。结果分析表明,该方案可在保证安全的同时实现高效数据传输。On the basis of the existing tree-based key pre-distribution schemes,this paper proposed a new hierarchical key management scheme in combination with the routing topology in WSN.Considering different communication requirements among sensor nodes,the inter-cluster protocol took re-encryption and authentication mechanisms while the intra-cluster assigned an administrative node for generating and maintaining the routing key tree.The results show that this new scheme can highly achieve secure and efficient data transmission.
