Abstract

The present description concerns a method of generation of a sequence of pseudo-random digital codes enabling to perform a permutation (3) of a first set of values (V) into a second set of values (Vp) based on said digital codes (CPos) representative of positions (j) of values (Vi) of the first set in the second set, including the steps of: generating, by successive iterations, a chain of numbers, called seed numbers, from an initial pseudo-random seed number (W0) by application of a first function (24,26) from a seed number to the next seed number; applying a second function to each seed number of the chain to obtain each position code (CPos(j)), the second function including at least one permutation (PERM) followed by a bijection (BIJ).
