摘　　要：无线Ad-Hoc网络密钥分发可以基于多种基本结构和混合结构。为寻找到更加高效的密钥分发结构,在研究基本结构和原混合结构密钥分发效率的基础上,组合两种密钥分发效率高的基本结构得到两种新混合结构,研究了它们的密钥分发算法和通信量公式,通过对比得出新混合结构密钥分发效率高于原混合结构的密钥分发效率,然后通过OPNET仿真所得到图形和数据验证了上面结论和公式的正确性。Key distribution in Wireless Ad Hoc Network may be based on many basic structures or compound structures.In order to find the more efficient structure for key distribution,the efficiency of key distribution for basic structures and former compound structures is studied first,and then two high-efficiency basic structures on key distribution is combined and thus two new compound structures are obtained.And then the key distribution and the communication formulas are studied,and a conclusion is acquired by comparison that the new compound structures are more efficient than the old one.Finally,the graphics and data produced from OPNET simulation indicate that this conclusion and those formulas are correct.
