Ad Hoc网络中一种基于信任域值的IDS模型的设计

Design of an IDS Model Based on the Trust Spectrum in Ad Hoc Networks

移动AdHoc网络由于具有开放媒质、动态拓扑和分布合作及能量受限等特点,特别容易受到攻击。在AdHoc网络中,每个节点充当路由器,寻找和保持到其他节点的路由。路由安全是保证AdHoc网络安全最重要的一环。本文采用决策支持系统中的信任机制将一种基于信任域值的IDS模型(IDS_trust)引入到AdHoc网络中,并提出了一种新的安全解决方案。

The mobile Ad Hoe network（MANETS） are vulnerable to attacks for the unique characteristics of MANETs, such as open network architecture, shared wireless medium, highly dynamic network topology, and stringent resource constraints. In MANETs, each node acting as a rooter to scarch and maintain the rool to the other nodes. Rool security is an especially important part in MANETs security, in this paper, we design an IDS model （called IDS_trust） based on the trusl spectrum by the trust mechanism in decision-and-support systems,and present a new security solution.
