Route Reliability Ranking Algorithm for Prefix Hijacking Attacks in Border Gateway Protocol

Prefix-hijacking attack offers malicious parties to gain access to untraceable IP addresses in Intenet. Border gateway protocol (BGP) is the dominant inter domain routing protocol used in Internet. In this paper, to defend against Prefix Hijacking Attack on border gateway protocol (BGP), we propose to design a route reliability ranking (RRR) algorithm. The algorithm is used to authenticate the validation of a routing update based on the common facts of the autonomous systems (AS’s) in the network. After RRR, an incentive based route selection mechanism is performed to identify the suspicious candidates and avoid routes propagated by them. By simulation results, we show that the proposed algorithm is efficient defensive technique for prefix hijacking attack in Internet.
