Abstract

L'invention concerne un dispositif et un procédé cryptographique pour générer des nombres pseudo-aléatoires (1), comportant les étapes suivantes ; subdiviser des données initiales (1) en une pluralité de mots (3) à b-bits définis dans un corps fini GF(2b ), affecter lesdits mots à des cellules (5) d'un tableau d'état (7) pour former un bloc d'état initial (13a), regrouper les cellules (5) dudit tableau d'état (7) pour affecter un groupe (11) de cellules à chaque ensemble de d /b mots, où d est un multiple de b strictement supérieur à b , et générer de manière itérative à partir dudit bloc d'état initial (13a), une succession de blocs d'états (13b) pour former un bloc d'état final (13c), de sorte qu'à chaque itération chaque ensemble de d /b mots d'un bloc d'état (13b) courant est remplacé par un autre ensemble de d /b mots, en utilisant, pour former un bloc d'état suivant, au moins une table de référence (9) comportant des éléments de substitution à d-bits.
