Method and device used for detecting authenticity of routing information

Abstract

The invention relates to a method and a device used for detecting the authenticity of routing information. The embodiment of the method for detecting the authenticity of the routing information comprises the following steps: setting and initializing a false routing information counter; detecting single routing information in the routing information sent to a detecting node by a detected node, and adding 1 to the false routing information counter when detecting that the single routing information is false routing information; judging that the detected node is a deceptive node and the routing information sent to the detecting node by the detected node is the false routing information when data in the false routing information counter exceeds a predetermined threshold value; and judging that the detected node is an honest node and the routing information sent to the detecting node by the detected node is true routing information when detection of the single routing information in the routing information is completed and the data in the false routing information counter does not exceed the predetermined threshold value. The embodiment of the invention ensures that the method used for detecting the authenticity of the routing information sent by a neighbor node is simple and effective.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and device for detecting the authenticity of routing information. Background technique [0002] A routing protocol is a communication protocol between routers, which can realize the sharing of routing information between routers. Routing protocols allow routers to exchange and maintain their own routing information, update and maintain dynamic routing tables to correctly reflect network topology changes, and routers determine the best path based on metrics to forward network data. [0003] Currently, distance vector protocols are widely used in small networks, and distance vectors are represented by routing metrics. Currently, widely used distance vector protocols include RIP and IGRP. Distance vector protocol routers regularly send their entire routing information table to adjacent routers. After receiving the routing information table, the adjacent router bu...

The disadvantage of this method is that it needs to establish a trust model to achieve detection

[0009] It can be seen from the above content that the existing technology requires nodes to know the topology of the network or to implement detection by establishing a trust model based on the existing distance vector protocol, and the detection method for the routing information sent by the neighbor node is relatively complicated
