The Resource Public Key Infrastructure (RPKI) binds IP address blocks to owners’ public keys. RPKI enables routers to perform Route Origin Validation (ROV), thus preventing devastating attacks such as IP prefix hijacking. Yet, despite extensive effort, RPKI’s deployment is frustratingly sluggish, leaving the Internet largely insecure. We tackle fundamental(More)
Extensive standardization and R&D efforts are dedicated to establishing secure interdomain routing. These efforts focus on two mechanisms: origin authentication with RPKI, and path validation with BGPsec. However, while RPKI is finally gaining traction, the adoption of BGPsec seems not even on the horizon due to inherent, possibly insurmountable,(More)
