摘要： 基于信誉机制的边界网关协议存在信誉值计算不合理和数据存储不安全等问题。为此，提出一种新的域间安全路由协议TBGP。从网络节点、链路和路径3个方面计算信誉值，以提高路由的安全性，并引入可信计算，利用自治系统联盟管理保证信誉值数据的完整性和存储的安全性。理论分析及仿真结果表明，该协议可较好地抑制不可信路由的传播，实现最优路径选择。

Abstract: Border Gateway Protocol(BGP) based on reputation mechanism has some defects such as unreasonable computing of reputation value and insecurity data storage. This paper proposes a new inter-domain routing protocol called Trusted Border Gateway Protocol(TBGP). In order to improve the security of routing, TBGP calculates reputation value from the three aspects of the network nodes, links and path. The trusted computing is also introduced to TBGP, and Autonomous Systems(AS) alliance management is used to ensure the integrity and security of reputation value. Analysis and simulation results show that TBGP can inhibit the spread of untrusted routing and help to choose the best path.
