The Internet's interdomain routing system is notoriously insecure. After more than a decade of effort, we are finally seeing the initial deployment of the Resource Public Key Infrastructure (RPKI), which certifies IP address allocations using a centralized infrastructure of trusted authorities. To further improve security, standards bodies are developing BGPSEC, a protocol for certifying advertised routes.
In this talk, I discuss the benefits and attendant complications of transitioning from legacy BGP to the RPKI and then to BGPSEC. I argue that transitioning to the RPKI is the most crucial step from a security perspective, but that it raises new technical and policy challenges. My argument is based on (1) our theoretical and experimental analysis of the security benefits of BGPSEC during the transition, when BGPSEC coexists alongside legacy insecure BGP, and (2) an analysis of the RPKI in a threat model where its trusted authorities are misconfigured, compromised, or compelled (e.g. by governments) to behave abusively.
