Abstract

L'invention concerne un procédé sécuriser un générateur (1) générant des nombres pseudo-aléatoires (5). Le générateur (1) est caractérisé par son état interne. Le générateur (1) comprend: - une première zone mémoire (2) contenant des bits d'état (3), représentant l'état interne dudit générateur (1), - une unité de calcul (4) effectuant des opérations arithmétiques sur lesdits bits d'état (3) pour produire lesdits nombres pseudo-aléatoires (5) et modifier lesdits bits d'état (3), - une seconde zone mémoire (6) contenant lesdits nombres pseudo-aléatoires (5), - une sortie unique (7) permettant de lire lesdits nombres pseudo-aléatoires (5) contenus dans ladite seconde zone mémoire (6). Le procédé selon l'invention comprend l'étape d'inhiber de manière irréversible et inconditionnelle, notamment par des moyens logiques et/ou mécaniques et/ou électroniques, la lecture et l'écriture desdits bits d'état (3) depuis l'extérieur dudit générateur (1), y compris via ladite sortie unique (7).
