If Amateur Radio's prohibition on encryption is considered to be important in making decisions about crypto in protocols, then I think we are in a situation where we can't have crypto protocols that don't disallow downgrade attacks, because implementations always have to be willing to downgrade to no encryption if the other endpoint is an Amateur Radio station. So, by reductio ad absurdum, I claim that this isn't something the working group should consider as a deciding factor. I think the same observation also applies to Michael's comment about debugging on stacks with limited trace capability. If you need to disable encryption, you should have to do something fairly extraordinary to make that happen. _______________________________________________ Hipsec mailing list [email protected] https://www.ietf.org/mailman/listinfo/hipsec
