Ad Hoc中一种基于双向认证AODV协议的研究

Research of a Mutual Authenticated Secure AODV Protocol in Ad Hoc

移动Ad Hoc网络是一种无中心自组织的多跳无线网络。由于无线介质的不可靠性和结点的移动性,以及网络中缺少基础设施,因此网络安全是一个严重的问题。路由的安全直接关系到网络的正常运行,在AODV的基础上,本文提出一种新的SAODV。这种协议利用双向认证和同时完成共享密钥的交换,保证了路由建立的正确性。最后对SAODV进行评估,给出了仿真结果。

Mobile Ad Hoc networks are multihop wireless networks which are acentric and self-organizing. Due to the unreliable wireless media, host mobility and lack of infrastructure in the network, the security of network is a critical problem. The security of routing is critical for the running of the Ad Hoc network directly. Based on the AODV protocol, we propose a mutual authenticated AODV protocol. With the mutual authentication between network nodes and the simultaneous exchange of keys in the route discovery of demand routing, the correctness of routing is ensured. Simulation results are given by evaluating SAODV.
