New York Times: The Key Vanishes: Scientist Outlines Unbreakable Code.

“A computer science professor at Harvard says he has found a way to send coded messages that cannot be deciphered, even by an all-powerful adversary with unlimited computing power. And, he says, he can prove it.

If he is right, and he does have some supporters, his code may be the first that is both practical and provably secure. While there are commercially available coding systems that seem very hard to break, no one can prove that they cannot be cracked, mathematicians say.”

Hey Al, I like your new photo! I also enjoyed your picture gallery. I’ve never peeked ‘behind the curtain’ in a hospital, and I’ve never been in an intensive care room.
