Generating chaotic sequences and corresponding generation system

摘要

Generator (2) of chaotic sequences eu (n), a strictly positive integer, integer values ​​represented in a number of quantizing bits determined N, intended in particular to form a encryption key information, said generator comprising n being (2 ) at least two discrete recursive filters (4, 6) of order at least equal to 1 generate outputs a chaotic sequence of integer values, each recursive filter (4, 6) comprising means of implementation (8 , 10) of a nonlinear function F, connected through an exclusive OR gate (12, 14) to means for generating a sequence of perturbation Q (n) of integer values ​​represented in a number of quantization bits k determined , wherein the two filters (4, 6) are mounted in parallel, with the chaotic sequence eu (n) output of the generator (2) equal to an exclusive OR (20) of the chaotic sequence output recursive filters (4 , 6), and that the means of implementation (8, 10) of the nonlinear function comprises a chaotic map.
