Abstract

Selon la présente invention, une application de restitution détermine que le contenu électronique est sous forme cryptée de protection des droits et appelle un système de gestion des droits d'utilisation électronique ou DRM (Digital Rights Management) qui inclut un magasin de licences dans lequel est rangée au moins une licence d'utilisation électronique. Chaque licence correspond à une oeuvre en format électronique et inclut une clé de décryptage (KD) permettant de décrypter le contenu électronique correspondant. Le système DRM place chaque licence dans le magasin de licences correspondant au contenu électronique à restituer, sélectionne l'une des licences rangées, va chercher la clé de décryptage (KD) dans la licence choisie, décrypte le contenu électronique au moyen de la clé de décryptage (KD), puis renvoie le contenu électronique décrypté à l'application de restitution en vue de la restitution proprement-dite.
