How do you generate "chaos"?
- Igor.
Chaos may be generated with dripping water faucets, with alpha particle emissions, with Johnson noise.
It matters not, though, as schemes like this are dependent on key exchange, and by repeatability of whatever "chaotic process" they employ.
They can be ignored.
The fact that "Nobuki Nakatuji" only appeared on our list days before the revealing of his profound new breakthrough is telling. And all too predictable.
Tim, my question was related to items 2 and 3. I think that Nobuku san suggested a way to generate a stream of pseudo-random bits from an inputted text. The important question is, how Prof. Nobuku is going to do it exactly. If done right, I believe that his system is great if the key is never reused. Is that correct? Sayonara - Igor.
