Hi-BGP: A Lightweight Hijack-proof Inter-domain Routing Protocol

BGP is the cornerstone of the Internet. However, the implicit trust assumption in BGP’s design destines its inherited vulnerability. Prefix hijacking is one of the large-scale BGPspecific routing anomalies that are able to paralyze the Internet. This calls for a hijack-proof security solution. By putting the protection against prefix hijacking the top priority, we design a lightweight hijack-proof BGP system – Hi-BGP. Hi-BGP utilizes the existing BGP system to distribute the relevant route validation information and use the information to prevent various prefix hijacking. In addition, we propose a transition scheme of HiBGP so that it can be incrementally deployed. At the same time, we show that Hi-BGP is lightweight and can be deployed in the Internet.
