Embodiment Construction

[0148] The realization of the present invention is elaborated as follows in conjunction with accompanying drawing:

[0149] 1. RLDA Architecture Design and Relay Network

[0150] Route leakage is an important reason that threatens the security of inter-domain routes and will cause large-scale network interruptions. Starting from the route leak threat model, under the guidance of the design goal, a route leak detection architecture (Route Leak Detection Architect, RLDA) is proposed. 1. Inter-domain routing model and autonomous domain business relationship classification

[0151] The inter-domain routing system can be abstracted as an autonomous domain-level graph G=(V,E). Among them, v∈V represents an autonomous domain, e∈E represents a connection between corresponding autonomous domains, and the type of connection represents the relationship between autonomous domains. The autonomous domain relationship is the result of abstracting the routing policy. Among them, the relat...

Abstract

The invention discloses a BGP (Border Gateway Protocol) route leakage detection method and system based on a block chain, and relates to the technical field of Internet security. The BGP route leakage detection method aims to solve the problems of poor accuracy and security of autonomous domain relational data, lack of a feedback mechanism and the like of the existing routing leakage detection mechanism. The technical key points are as follows: managing autonomous domain relation data published by an autonomous domain: a routing policy, an autonomous domain relation and a routing expectation; the BGP route leakage detection method is used for deducing an autonomous domain relation through a routing strategy and issuing a routing expectation, and the routing expectation means that the autonomous domain describes a future complex legal routing mode; routing leakage occurring in an autonomous domain path is detected by using a legal routing mode described by autonomous domain relational data, detecting is performed by using a routing leakage detection technology based on a valley-free rule hypothesis, and if the routing leakage is found, mitigation processing is performed on the influence of the routing leakage; and if no routing leakage is found, only the autonomous domain relation data is fed back. Through verification, the accuracy of the autonomous domain relation inference algorithm based on the routing strategy can reach 99%.

Description

technical field [0001] The invention relates to the technical field of Internet security, in particular to a BGP route leakage detection method and system. Background technique [0002] 1. Basic overview [0003] The Internet is divided into many AS (Autonomous System, autonomous domain system). The autonomous domains use BGP (Border Gateway Protocol, Border Gateway Protocol) to exchange routing information, and follow the routing policy agreed between the autonomous domains. The formulation of the import (import) and export (export) policies in the routing policy depends on the commercial relationship between autonomous domains (abbreviated as autonomous domain relationship). Route propagation that violates the routing policy is called a route leak. [0004] In Gao et al. [1] In the proposed autonomous domain relationship model, according to the agreement between autonomous domains, autonomous domain relationships can be divided into c2p (customer-provider, customer to ...
