Securing BGP — A Literature Survey

The Border Gateway Protocol (BGP) is the Internet´s inter-domain routing protocol. One of the major concerns related to BGP is its lack of effective security measures, and as a result the routing infrastructure of the Internet is vulnerable to various forms of attack. This paper examines the Internet´s routing architecture and the design of BGP in particular, and surveys the work to date on securing BGP. To date no proposal has been seen as offering a combination of adequate security functions, suitable performance overheads and deployable support infrastructure. Some open questions on the next steps in the study of BGP security are posed.
