域间路由系统中自治系统间信任关系的建立和维护方法技术方案

本发明专利技术涉及一种基于贝叶斯估计的域间路由系统中自治系统间信任关系的建立和维护方法。通过以下步骤，完成系统中自治系统间信任关系的建立和维护：（1）参数初始化,即定义并初始化建立自治系统间信任关系所需的参量；（2）域间路由消息真实性的检测，即自治系统系统判定收到的域间路由消息是否与真实的网络拓扑相符，并统计检测结果；（3）基于路由检测的信任度更新，即自治系统根据对来自邻居自治系统的路由消息的检测结果，实时地更新对其的信任度；（4）自治系统信任等级判决，即根据自治系统的当前时刻信任度，把自治系统划分为低、中、高三个信任等级，然后按等级对其发送的路由更新数据包直接丢弃，或者进行检测，或者直接用来更新路由列表。

Method for establishing and maintaining trust relation among autonomous systems in inter domain routing system

The invention relates to a method for establishing and maintaining a trust relationship between autonomous systems in an inter domain routing system based on Bayesian estimation. Through the following steps to complete the establishment and maintenance of trust relationship between autonomous systems: (1) the parameter initialization, parameter is defined and initialized to establish a trust relationship between autonomous systems required; (2) inter domain routing message authenticity detection, autonomous system routing system determines the received message is consistent with inter domain real network topology, and statistical test results; (3) the trust update routing detection based on autonomous system according to the detection result of routing messages from a neighbor autonomous system, real-time update the confidence of its autonomous system; (4) the trust level of judgment, according to the current trust autonomous system the autonomous system, divided into low, medium and high trust levels, and then press the grades on its send routing update packets discarded directly, or for testing, or straight Is used to update the routing list.
