Abstract
L'invention est un système de production de séquences de bits pseudoaléatoires qui peut être utilisé pour chiffrer des données numériques avant leur transmission ou leur stockage. La séquence de bits est obtenue par un développement d'une pluralité de bits de clé secrète d'une façon qui peut être incorporée à une unité arithmétique et logique à microprocesseur courant. Le système de la présente invention peut être utilisée, par exemple, pour protéger les communications vocales et les transmissions de données entre une station de base et une station mobile dans un système de communication cellulaire numérique.
