Abstract
Techniques for mitigating BGP blackholes and hijackings are disclosed herein. The techniques include methods for determining, by a victim autonomous system (AS), that a first AS is associated with a first BGP route that includes the victim AS as the destination or as an AS along the first BGP route to the destination and sending a message to a second AS directing the second AS to refrain from using the first AS to propagate data to the victim AS. The message can include a set of one or more AS numbers to avoid in refraining from using to propagate data to the victim AS, a timestamp, an expiration interval, a signature of the victim AS, and an identifier identifying a certificate to be used to verify the signature. Systems and computer-readable media are also provided.
