Title (EN) CACHING OF ENCRYPTED CONTENT
(FR) MISE EN ANTÉMÉMOIRE D’UN CONTENU CRYPTÉ
Abstract:
(EN) The invention relates to a transparent proxy as well as methods of caching and providing encrypted data content at the transparent proxy. In a first aspect of the present invention, a method of providing requested encrypted data content at a transparent proxy (12) in a communications network is provided. The method comprises receiving from a client (10) an encrypted identifier indicating the requested encrypted data content at the proxy, identifying the encrypted data content from the received encrypted identifier, determining whether the client is authorized to access the encrypted data content, and if so providing the requested encrypted data content to the client.
(FR) L’invention concerne un serveur mandataire transparent ainsi que des procédés de mise en antémémoire et de fourniture de contenu de données crypté exécutés au niveau du serveur mandataire transparent. Un premier aspect de la présente invention concerne un procédé pour fournir à un serveur mandataire transparent (12) d’un réseau de communication un contenu de données crypté demandé. Le procédé consiste à recevoir d’un client (10), au niveau du serveur mandataire, un identifiant crypté indiquant le contenu de données crypté demandé, à identifier le contenu de données crypté d’après l’identifiant crypté reçu, à déterminer si le client est autorisé à accéder au contenu de données crypté et, s’il y est autorisé, à présenter au client le contenu de données crypté demandé.
