Forgive me, but isn't this just the standard technique for calculating these things? Recall the algorithm for calculating points in the mandelbrot set -- a point X0 is in the set if the infinite series described above converges to a value within certain bounds? [The infinite series defined by X0 = something Xn+1 = a * (Xn) * ( 1.0 - (Xn) ) ] This iterative technique is the fundamental idea behind the creation of the mandelbrot set and Julia sets, as I recall. I don't know anything at all about the "Chaos Cryptosystem Algorithm", but there might actually be more to it than just another onetime pad. -- Kent Crispin "No reason to get excited", [email protected] the thief he kindly spoke...
