为在没有固定基站或中心节点的移动Ad Hoc网络中实现身份认证机制,提出了一种无需任何信任第3方认证服务器的动态信任模型.在该模型中,邻居节点间通过相互认证来建立路由信息.利用该动态信任模型组建了一个可信任的Ad Hoc网络.分析结果表明,本协议增强了网络安全性,提高了路由建立效率. In order to realize the identity authentication mechanism in the mobile Ad Hoc network without fixed base station or central node, a dynamic trust model without any trusted third-party authentication server is proposed, in which the neighboring nodes establish the mutual authentication route Information.Using this dynamic trust model, a trusted Ad Hoc network is established.The analysis results show that this protocol enhances the network security and improves the routing establishment efficiency.
