The only valid defense against such mucking that I can think of is verifying AS adjacencies against some registry and flagging unknown paths. This is not a cheap thing to do.

You can cryptographically sign bad information as well as good information. Cryptography is good for detecting alterations, not if the information was correct in the first place.
