移动Ad hoc网络按需路由协议中的虫洞问题研究

由于移动Ad hoc网络具有动态变化的特性以及自组织和多跳性的特点,更容易遭受多种恶意攻击。其中虫洞攻击就是最严重的一种攻击。本文详细剖析了虫洞问题,在总结已有解决方案的基础上提出了一种简洁的解决方案。此方案利用路由发现过程中中间结点计算的MAC值以及邻居维护机制提供的认证信息一起能够很好的抵抗虫洞攻击,提高了路由协议的安全性。

Research on the Wormhole of On-demand Routing in Mobile Ad hoc Netwoks

Mobile Ad hoc networks which has the dynamic and self-organization and multi-jumping feature is more vulnerable to a variety of malicious attacks.Wormhole is the most serious attack.In this paper,it analyzed in detail the wormhole problem,and proposed a strategy to solve it.The chained k-MAC values computed by all intermediate nodes during the route discovery,together with the authenticated neighbor information provided by the neighbor maintenance scheme,enable it to detect wormhole and varied attacks deriv...
