A digital random-number generator based on the chaotic signal algorithm

A digital random-number generator is developed and implemented based on the discrete chaotic-signal algorithm. The digital generator employs the matri x method of chaotic-signal synthesis. The sequence of 8-bit numbers produce d by the digital generator is determined by a set of initial data, a variet y of versions of which are stored in the generator's read-only memory. Swit ching the set of initial conditions in accordance with a predetermined prot ocol can be used to dynamically change the password. The digital generator is intended to operate as a coder-decoder in communications systems with wi deband chaotic signals.
