I think that what Nobuku described is not a private key system (because keys cannot be reused), but rather an approach to generating one time pads. Whether something that is interesting to me should also be interesting to you is open to question. > Do you think means of generating one time pads have been lacking?

So what if he reinvents something? Most of what high school and undergrad students do is learning and reinventing ideas that are already known. That does not make study less exciting. The interesting question that Nobuku can answer is how he generates the key from the input. - Igor.
