Abstract

L'invention concerne un dispositif et un procédé de génération d'une séquence de données pseudo aléatoire (1) à partir d'un flux de données initial (3) caractérisé en ce qu'il comporte les étapes suivantes : -définir un ensemble de mots de code formant un code préfixe complet (5), -définir un ensemble de mots de sortie (7), -définir une fonction de désynchronisation ( ƒ ) associant à tout mot de code dudit code préfixe complet (5) un mot de sortie dudit ensemble de mots de sortie (7), -décomposer le flux de données initial (3) en une suite de mots codée (11) conformément audit code préfixe complet (5), -associer les mots de ladite suite de mots codée (11) aux mots de sortie correspondants conformément à ladite fonction de désynchronisation ( ƒ ) pour former ladite séquence de données pseudo aléatoire (1).
