Abstract

La présente addition porte sur un contrôleur de nombre par nombre clé, tel que décrit dans le brevet principal, selon lequel on associe à chaque nombre A un nombre clé q obtenu à partir du nombre A. Le nombre clé q est obtenu en prenant le complément à p du reste de la division de A par le nombre p Contrôle effectué en temps réel en utilisant des composants simples.
