Improve Routing Security by validating BGP (Border Gateway Protocol) with RPKI (Resource Public Key Infrastructure) (2022)

By Tony Tauber, Courtney Smith; Comcast

In this paper, we will discuss the basic operation of BGP and inter-provider Internet routing including some vulnerabilities of the system. We will then describe RPKI, a set of technologies developed by the IETF (Internet Engineering Task Force) to help address a sub-set of these vulnerabilities. Deployment of these tools is not without risk and complication, and we will describe how we went about assessing and enabling RPKI in a large MSO network including design tradeoffs and lessons learned.
