therefore registrars (like alice's... remember alice? this is a song about alice) ( first, i suspect much of the confusion could come from your thinking that the place up on skyline is *the* alice's restaurant. it isn't. the real one was in stockbridge, mass, and rather short-lived. so you can see why one might wonder about isc's validation methods. :-) Actually, Paul might have been talking about Alice, Bob, and Mike. Well knows personages in cryptography circles. Alice and Bob want to exchange keys Mike is in the middle trying to figure out what alice and Bob are up to and also trying to thwart the exchange if possible. Or at the very least, gain knowledge of the keys so that Mike can read Alice's and Bob's message traffic.
actually, in a brilliant demonstration of fair use of copyrighted lyrics, paul was quoting directly from the song about alice's restaurant. well, actually, despite saying so, it's not much about the restaurant at all. "and the restaurant is not called alice's restaurant, that's just the name of the song." although i occasionally slum in the security community, i am not aware of a similar song about alice, bob, and mike; though i am more used to other attackers than mike. it might help if you were a 20-something in the '60s. then again, it is not helping me a lot these years. but perhaps we have gone adrift. randy
