中文摘要：

传统的信任模型在域间路由系统中存在着证书管理困难等问题。针对域间路由系统结构的特点，提出一种新的信任模型-TTM（Translator Trust Model）.分析结果表明，TTM在满足一定安全需求的基础上，其证书规模仅为传统模型的1％，具有良好的规模可扩展性.

The main problem of traditional trust model in inter-domain routing is the diffieuhv of certificate management.We have studied the architecture property of iuter-domain routing system,and proposed TFM （Translator Trust Model） as a new trust model.Analytical results demonstrate the TTM can satisfy the request of inter-domain routing security and has good sealabilitv.The number of the used certificates is about 1% of the traditional model.
