A PSEUDO-RANDOM NUMBER GENERATOR (10), AND AN ASSOCIATED METHOD, GENERATES A PSEUDO-RANDOM NUMBER. THE PSEUDO-RANDOM NUMBER IS A COMPLEX, LINEAR COMBINATION OF VALUES OF INPUT SEQUENCES PROVIDED TO THE GENERATOR (10) AND EXHIBITS LITTLE CORRELATION WITH SUCH INPUT VALUES. THE GENERATOR INCLUDES A SUMMATION COMBINER (12) AND AN IIR (INFINITE IMPULSE RESPONSE) FILTER (18) CONNECTED IN A FEEDBACK CONNECTION WITH THE SUMMATION COMBINER (12). BECAUSE OF THE LOW CORRELATION OF THE PSEUDO-RANDOM NUMBER AND INPUT VALUES PROVIDED TO THE GENERATOR (10), THE PSEUDO-RANDOM NUMBER IS LESS SUSCEPTIBLE TO CRYPTANALYSIS BY AN UNAUTHORIZED PARTY. |
