摘要
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。
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 derived from it,which can enhance the safety of routing protocol
