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。

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.

Key words: mobile Ad hoc network, wormhole attack, end-to-end, shortest path length, trust model, intrusion detection
