Abstract

Système de génération de nombres aléatoires dans un système de traitement de données. Le système comporte une horloge 4 à huit positions binaires incrémenté par le compteur 2 toutes les 10 ms, qui est échantillonnée dans les circuits ET 11 à 18 à des intervalles de temps t1 arbitraires et t2 , t3 , t4 qui sont des impulsions de sortie aléatoires obtenues par l'échantillonnage de configurations particulières du registre de comptage 5 incrémenté toutes les 7ms donc asynchrone à l'horloge 4. Un tel système permet la génération de nombres aléatoires employés comme mots de passe pour les utilisateurs d'un système de traitement de données.
