Professor Describes Unbreakable Cryptosystem?

split horizon writes: "The New York Times is reporting that Professor Michael Rabin of Harvard University claims to have developed a cryptosystem that is both practical and provably unbreakable. It sounds to me like it basically uses a one-time pad that's generated on the fly very quickly." Good stuff, but don't expect to see this in the next version of gnupg - the logistical difficulties are high and the system you'll end up with won't be any more secure in practice than public-key encryption techniques already widely available.
