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.
This is how it works:
make a code based on a key that vanishes even as it is used. While they are not the first to have thought of such an idea, Dr. Rabin says that never before has anyone been able to make it both workable and to prove mathematically that the code cannot be broken. |
the message stays secret forever because the code uses a stream of random numbers that are plugged into the key for encoding and decoding. The numbers are never stored in a computer's memory, so they essentially vanish as the message is being encrypted and decrypted.
If this is true, you will be able to send e-mail that can't be read by let's say BSA and friends
