摘要
Ad Hoc网络的关键技术是路由技术,对网络整体性能产生着最重要的影响,针对Ad Hoc网络动态变化的拓扑结构,原有固定网络中的路由协议已经能满足其需要,要求必须对新的Ad Hoc路由协议进行设计。基于Ad Hoc网络的基本概念,以双线性对和层次路由协议为基础,提出ad hoc网络中通信有效的密钥协定协议,对应逻辑密钥协定模型与实际网络拓扑结构,使建立和动态更新初始群密钥得到了支持,具有较小的通信量。实验和性能分析后得知,针对有较大的范围、较强的设备处理能力,而较差的通信环境而言,提出的协议效果非常好。
Routing technology is a key technology of the Ad Hoc network, and it is also one of the most important factors that affect the performance of the network as a whole. As the routing protocols in the traditional fixed networks no longer adapt to the dynamic changes in the topology of Ad Hoc Networks, new Ad Hoc routing protocols must be redesigned. Starting from the basic concept of the Ad Hoc network, an ad hoc network communication effective key agreement protocol based on bilinear pairings and hierarchical routing protocols is proposed. It supports the establishment and dynamic update of initial group secret key and has less traffic that corresponds to the logical key agreement model and actual network topology. The experiment and performance analysis show that the proposed protocol is very effective in the situation of large range, strong ability of equipment processing and poor network communication environment.
