>> o We can not know intent, should Mary have announced the prefix to Bob Let me point out a fundamental issue here. Security is, and always has been, about matching intent with reality. If I lock my doors, there is an implied intent that no-one go into my house (in band). If I give a neighbor a key, I will give them explicit instructions as to my intent --"only go in if the dog is barking, or to feed the dog, or..." (out of band) You MUST know intent to provide security. Get over it. You can't match expectations to reality unless you know what the expectations are. What is the entire security model of the RPKI and origin auth? To ensure the intent of the RIR in assigning address space is followed, and to ensure the intent of the owner of that address space is carried out. You could argue that you're only trying to secure the "semantics of BGP," which means you're trying to enforce the intent of the BGP specifications (you can't get away from intent!), but that opens up another wormhole of problems. "You can't prove intent" is a red herring. :-) Russ
