Abstract

Cette invention concerne un système et un procédé de sécurité de contenu numérique. Ce procédé consiste à chiffrer une clé nécessaire à la reproduction de contenu numérique, à fragmenter la clé chiffrée et à intégrer les fragments dans des parties de données utiles ; à chiffrer des parties déterminées de trames du contenu numérique et à utiliser la clé déchiffrée pour déchiffrer les parties chiffrées en vue d'une reproduction en temps réel. Ce procédé nécessite une session authentifiée active pour accéder à la clé chiffrée et la déchiffrer et pour accéder aux parties chiffrées et les déchiffrer.
