CA 2473851

A method and system for transmitting content from a content provider to a caching server and then from the caching server to a viewer. The method comprises encrypting the content with a pre-encryptor application before the content is transmitted to the caching server. The pre-encryptor application uses a pre-encryption subkey provided by a key storage service to perform the pre-encryption. The key storage service is a stand-alone component of the system and generates, stores, and distributes the pre-encryption subkeys.

La présente invention concerne un procédé et un système pour transmettre un contenu d'un fournisseur de contenu à un serveur de mise en antémémoire, puis de ce serveur de mise en antémémoire à un observateur. Ce procédé consiste à chiffrer le contenu avec une application de pré-chiffrement avant que le contenu ne soit transmis au serveur de mise en antémémoire. Cette application de pré-chiffrement utilise une sous-clé de pré-chiffrement fournie par un service de stockage de clés afin de réaliser le pré-chiffrement. Le service de stockage de clés est un composant autonome du système et produit, stocke et distribue les sous-clé de pré-chiffrement.
