Abstract
A finite state machine for producing a stream of pseudo-random numbers, having characteristic positive integral values S and T. The finite state machine has a w-bit non-linear combiner having an input and an output, a plurality of w-bit registers including at least a chained series of S registers and a chained series of T registers. The non-linear combiner receives as the input data from the last of the chained series of S registers and from the last of the chained series of T registers. The first of the chained series of T registers receives input from the last of the chained series of S registers. The first of the chained series of S registers receives input from the output of the non-linear combiner.
