Abstract: To further enhance the security of Ad Hoc networks, it presents a novel transitive trusted chain with Trusted Platform Module（TPM） in Ad Hoc networks. A scheme which extends the trusted relationships from the node of Ad Hoc networks to Ad Hoc networks as its design objective is proposed, and the trusted relationships between peers can be evaluated with a trusted model in Ad Hoc networks. Authenticated Routing for Ad hoc Networks（ARAN） is improved by introduction of trusted level and then it selects the routing of highest trusted level. The trusted transfer model in Ad Hoc networks is analyzed.

Key words: trusted chain, Ad Hoc networks, trusted model, trusted level

摘要： 为了进一步提高Ad Hoc网络的安全性，提出一种利用可信平台模块传递信任链的方案。该方案以将信任关系从Ad Hoc网络节点扩展至Ad Hoc网络为设计目标，利用信任模型评估每个节点的信任度，在ARAN安全路由协议的基础上，结合信任度对ARAN安全路由协议进行了改进，选出一条可信度最高的路由，对可信链传递方案进行性能分析。
