中文摘要： 在日趋紧张的频谱资源环境中，不依赖于固定基础设施和固定频谱分配策略的认知Ad hoc网络相关技术已经获得了十分迅速的发展。但是，认知Ad hoc网络的多信道路由特点使其收益与风险并存，面临着严重的安全问题困扰。保障认知Ad hoc网络安全的首要前提是在认知节点之间建立信任关系，而信任管理正是解决多信道路由安全问题的基础。同时，多信道路由特点又使得认知Ad hoc网络信任管理有别于传统无线网络，在节点路由和多信道选择方面呈现出双重性特征。 本课题旨在全面系统地探究面向认知Ad hoc网络多信道路由的信任管理。主要研究内容包括认知Ad hoc网络信任管理的基本要素及其健壮性研究、基于信任管理理论的多种类型频谱感知数据伪造攻击防御方法研究。在此基础上，构建双重信任管理机制，实现节点路由和多信道选择方面信任管理的相互协作与有机联动。本课题的研究对于有效提升认知Ad hoc网络的安全性具有重要意义。

英文摘要： In the environment of scarce spectrum resources, cognitive Ad hoc network which is independent with infrastructure and fixed spectrum allocation policy，has been also developed quickly.Due to the characteristic of multi-channel routing, cognitive ad hoc network is commonly perceived as an environment offering both opportunities and threats. To keep the security of cognitive radio network, the most important solution is to build trust relationship among cognitive users. Trust management is just the basic technology to solve the security problems of multi-channel routing. Meanwhile, the characteristic of multi-channel routing also makes the trust management of cognitive ad hoc network be different from traditional wireless network. The trust management is dual in terms of the node routing and the multi-channel selection . The main purpose of this project is to research the trust management related on multi-channel routing for cognitive ad hoc network comprehensively and systematically. The researches include analysis of basic elements and reliability for cognitive ad hoc network trust management, the defense of various kinds of spectrum sensing data falsification attacks based on trust management theory. In this basis, this project designs a dual trust management mechanism to fuse the the trust management of both t
