Abstract

L'invention concerne un procédé de génération de clés électroniques d pour procédé de cryptographie à clé publique au moyen d'un dispositif électronique. Selon l'invention, le procédé comprend deux étapes de calcul dissociées. Une étape A consiste à - calculer des couples de nombres premiers (p, q), ce calcul est indépendant de la connaissance du couple (e, l) e l'exposant public et l la longueur de la clé du procédé de cryptographie et à - stocker les couples ainsi obtenus. Une étape B très rapide qui peut être exécutée en temps réel par le dispositif, consiste à calculer une clé d à partir des résultats de l'étape A et de la connaissance du couple (e, l).
