• Resource Public Key Infrastructure (RPKI)
  • RPKI provides origin IP and IP prefix verification (protection against Sub-Prefix Hijacking Attack), while BGPSec provides AS path verification (protection against Shortest AS Path/One-Hop Attack). For full protection, both RPKI and BGPSec have to be implemented by all ASes along the path from the source to the destination.
