一种新的Ad hoc网络安全路由方案

在移动Adhoc网络中,网络的自组织、动态拓扑以及无线接入等特点使得路由的安全性问题日益突出。论文提出了一种基于按需路由的高效、安全路由方案(ESAR),阐述了该方案的原理,路由发现和路由维护过程,并对其安全性能以及网络性能进行了分析,与同类型的方案进行了比较。该方案可以有效地防止对路由信息的伪装、篡改、路由重播、拒绝服务(DoS)等攻击,并且考虑了Adhoc网络资源有限的特点,使用对称密钥机制,降低网络资源的开销。

Efficient and secure routing approach for Ad hoc network

In mobile Ad hoc networks,routing security has become an important issue due to the self-organize,dynamic topology and wireless surrounding of networks.Of all the current routing protocols,many take into account routing security under the assumption of existing security association while some use the expensive public key mechanism.These protocols cannot deal with attacks efficiently.This paper proposes an efficient and secure routing approach for Ad hoe network,specify its routing process, analyzes its security performance and network performance,and compared it with the existent protocols.The new approach can solve security problems such as fabrication,modification,routing replay attack in mobile Ad hoc networks.And it also considered the resources are constrained in Ad hoc network.
