Abstract

Au niveau d'un fournisseur de contenu, l'invention permet de fournir un contenu à diffuser à une pluralité de dispositifs mobiles. L'invention concerne une méthode pour distribuer des clés pour décoder un contenu. Cette méthode consiste à fournir une pluralité de clés de décodage codées. Ces clés de décodage codées sont codées selon fSMK(gPK(CEK)), f et g étant des fonctions de codage, fSMK désignant une fonction de codage codant gPK(CEK) selon une clé SKM, gPK(CEK) désignant une fonction de codage codant CEK selon une clé PK, et CEK désignant une clé de codage de contenu permettant de décoder le contenu pendant une cryptopériode unique. La méthode consiste également à émettre la pluralité de clés de décodage codées à la pluralité de dispositifs mobiles susmentionnés, et à un moment approprié se rapportant à la diffusion du contenu codé selon la clé CEK, à transmettre la clé SKM à la pluralité de dispositifs mobiles, ce qui permet d'activer la pluralité de dispositifs mobiles pour décoder fSMK(gPK(CEK)) et pour dériver gPK (CEK). L'invention concerne encore un appareil et des méthodes associées.
