:What I am thinking is to have one person encrypt using a RNG (noise). He :encrypts his message using the noise on one channel and then copies the noise :utilized on another channel. He then mixes the two channels to :create....noise. What you mean is generating a random one-time-pad, encrypting with that pad, and sending the pad to the recipient via secure means. I think it has been done before :-) If your idea of sending the 'random noise' is something electronic rather than a black bag, then all you've done is re-invent security through obscurity and your program is little more than hiding plaintext with a stego program. :On the other side the person must be expecting the noise and must know how to :seperate the signal. It seems that this leaves things open by having the :encryption key along with the message, but the message itself is just noise. :(i.e. the interloper must know of the signal, and know how to split it into :it's two components.) Oops. Sure sounds like you meant the security through obscurity option... :::::Comments? You design anything important for Microsoft then??? G
