Narrator: Talk show.
A first man, presumably clean-shaven, and a second man, who apparently has a beard, sit at a round table. On the table can be seen a microphone and a loudspeaker.
First man: Our guest, Mr. Bruce Schneier, says credit cards ought to use public-key cryptography.
Second man: Then nobody could charge your card without your permission.
First man: An industry representative is on the line with us.
Voice from loudspeaker: We've been using public-key encryption for years.
Voice from loudspeaker: Your credit card number is your public key. You must disclose it when you use it.
The second man gesticulates.
Second man: Nonsense! If credit card numbers are public keys, then why would anybody steal 40 million of them?
Voice from loudspeaker: That's the beauty of it.
Voice from loudspeaker: It does double duty.
Voice from loudspeaker: Your credit card number is also your private key.
Voice from loudspeaker: That's why we recommend that you keep it private.
The second man is seen clutching at his head with both hands.
Second man: Omigod.
First man: Mr. Schneier?
Second man: I'm speechless.
Voice from loudspeaker: Well, sir, you should be.
