摘　　要：基于双线性对和层次路由协议提出了一个Ad Hoc网络中通信有效的密钥协定协议,使逻辑密钥协定模型和实际网络拓扑结构对应,支持初始群密钥的建立和动态更新,通信量较小。对范围较大、设备处理能力较强,但通信环境稍差的网络非常有效。A secure communication-efficient key agreement protocol based on the bilinear pairings in Ad Hoe networks was proposed. In this protocol, the dynamicity of the networks was considered and the 1-hop assumption was weakened by employing hierarchical routing techniques to ensure that the logical model of key agreement consists with the actual topology of networks. As a result, the communication overhead was reduced. The analysis result shows that the proposed scheme is applicable to Ad Hoe networks with large size.
