Abstract: Wormhole attack is a severe attack in Ad hoc network. In the wormhole attack, two malicious nodes are sent and re-transmit packet received at one end of the wormhole to the other end. In this way, wormhole attack disrupts the network routing by generating shortest path. This paper proposes a novel end-to-end wormhole detection method based on trust model.

摘要： 虫洞攻击是一种针对Ad hoc路由协议，破坏网络路由机制的攻击，它是Ad hoc网络的重大安全威胁。该文提出一种基于信任评估的端到端虫洞检测方法，估算源节点和目的节点间最短路径长度，根据路由长度和邻居节点信任度来选择路由，从而检测和防御虫洞 攻击。
