Border Gateway Protocol Routing Neighbor Trust Mechanism Based On Game Theory

As the size of the Internet has grown,cybersecurity incidents have become more frequent.The security of the BGP protocol---Border Gateway Protocol has alsoattracted a lot of attention.The traditional BGP protocol lacks a mechanism to ensure information security.Security attacks against BGP have occurred repeatedly.Therefore,the security research of BGP is very important.Although many companies and research institutes have proposed many solutions in recent years,these security solutions are more or less lacking in actual deployment or use efficiency.Therefore,research on how to effectively ensure the security of BGP is still one of the core issues in the field of information security.BGP security vulnerabilities are mainly reflected in the following two aspects:In an BGP system,when an AS announces,there is no effective way to prove whether the contents of the NLRI field and the AS_PATH attribute in the Update message are true messages;in the BGP speaker and neighbors When a BGP speaker communicates,the integrity of the update message and the authenticity of the neighbor's identity cannot be guaranteed.In view of the authenticity of BGP neighbor identity,game theory---a pre-existing decision-making analysis theory can solve this problem well.Therefore,this paper designs a routing gateway routing neighbor trust mechanism based on game theory.This paper introduces the basic knowledge of BGP and game theory,as well as the security of BGP.Then,through the game theory theory,the BGP game model is established.Based on the model,a set of "humanized" punishment mechanism is established to punish selfishness..The AS routes the nodes and motivates the nodes to choose friendly policy behaviors to maximize the benefits.Finally,the establishment mechanism of BGP neighbor based on the above research is proposed,and the specific implementation method of the mechanism is given.In summary,the main research results of this paper are as follows:(1)A BGP model based on game theory is proposed.(2)According to the game model and reputation effect,a humanized punishment mechanism is designed to punish selfish AS nodes and encourage nodes to choose friendly strategic behavior.(3)The specific deployment plan of the mechanism is designed,and the specific implementation method of establishing the neighbor relationship and maintaining the neighbor relationship is given.Compared with the existing BGP security scheme,the mechanism does not need to modify the original protocol of the BGP route.It does not need to deploy complex key management facilities.At the same time,the number of monitoring nodes can be increased or decreased according to the needs of users.The level of security needs,and the security level is set autonomously.Provides strong support for BGP security.
