Abstract: Most recent security-related research on Ad Hoc network focuses on malicious nodes which do the misbehavior alone. This paper details a collaborated attack method——tunnel. Through simulation based on the DSR routing protocol and NDM security method, it shows that the tunnel attack is feasible to take considerable intrusion effect even the NDM is enabled. The corresponding security advice is given in the conclusion based on the evaluation results.

摘要： 目前MANET中安全方面的研究大多是对单个节点实施的恶意行为的分析和防范。该文研究了一种多节点配合的攻击模式——隧道攻击。结合DSR路由协议和NDM安全模型验证了隧道攻击的有效性和对网络的危害性，提出了设计相应安全措施的方向。
