Ok, here was the method of key generation i was talking about. With the light communications, the idea was to use photons whose waves pulsed in certain directions (up/down, left/right, and diagonally) to create a way toommunicate much like morse code. The key used to scramble these communications was designed to change the direction the photons of a message pulsated - like changing the characters of a message, scrambling it up. The key consisted of three symbols, one for each of the possible orientations, and was fainly simple. It was like a one time pad in that the key was never recycled. The key could be generated by a game of 20 questions, so to speak. The people at either end randomly generated a key. Then, they asked eiither indirect questions about the contents of one anothers key (do you have an odd number of up/down symbols in row x, etc), but since the contents of the key were never touched on DIRECTLY, no eavesdfropper could determine the key, and it was ttally secure. We, obviously, cannot use the photon as a method of communication, not for th e masses. the undertaking of building such a network from scratch is astronomical. however, if one wwas to use the orientation symbols in ones messages, as if they were being beamed, but in an email message instead, one could make use of the simple key, and the simple game of '20 questions' to generate a totally secure key in a mater of minutes, depending on how long the message was and therefore how long the key has to be. Does any of this make sense? Regards, Munster. --- _________________________________ *!Cheese Doctrine:!* Though cultured over time, and aged to perfection, one must not yield to produce mold.
