One-Time Pad From Caltech Offers Uncrackable Cryptography

zrbyte writes "One-time pads are the holy grail of cryptography — they are impossible to crack, even in principle. However, the ability to copy electronic code makes one-time pads vulnerable to hackers. Now engineers at the California Institute of Technology in Pasadena, have found a way around this to create a system of cryptography that is invulnerable to electronic attack. Their solution is based on a special kind of one-time pad that generates a random key through the complexity of its physical structure, namely shining a light through a diffusive glass plate."

So, the message can only be read by the light of a moon the same shape and season that the message was written on?

Uncrackable glass plates? Forget cryptography, you should get into the windshield business!

What if you drop the glass plate? You're sure to crack it then.

This [xkcd.com] seems a little bit more appropriate.

All she does is sneak into his hotel room when he's asleep, generate his pad using his crystal and make a copy of it.

Sounds like a metaphor for something kinky...
