Title (EN) METHOD AND SYSTEM FOR EFFICIENT ENCRYPTION, TRANSMISSION, AND DECRYPTION OF VIDEO DATA
(FR) PROCÉDÉ ET SYSTÈME DE CHIFFREMENT, DE TRANSMISSION ET DE DÉCHIFFREMENT EFFICIENTS DE DONNÉES VIDÉO
Abstract:
(EN) One embodiment provides a system for efficiently and securely encrypting, transmitting, and decrypting video data, including selective encryption of image frames. During operation, the system obtains by a content-transmitting device, an image frame which is used to form a video stream. In response to determining that the image frame satisfies a predetermined condition for encryption, the system encrypts the image frame based on an encryption algorithm. The system encapsulates the encrypted image frame based on encapsulation information. The system includes encryption identification information for the image frame in the encapsulation information.
(FR) L'invention concerne, dans un mode de réalisation, un système destiné à chiffrer, à transmettre et à déchiffrer de manière efficiente et sécurisée des données vidéo, comprenant un chiffrement sélectif de trames d'image. En cours de fonctionnement, le système obtient, de la part d'un dispositif émetteur de contenu, une trame d'image qui est utilisée pour former un flux vidéo. En réaction à une détermination selon laquelle la trame d'image satisfait une condition prédéterminée pour le chiffrement, le système chiffre la trame d'image selon un algorithme de chiffrement. Le système encapsule la trame d'image chiffrée d'après des informations d'encapsulation. Le système inclut des informations d'identification de chiffrement relatives à la trame d'image dans les informations d'encapsulation.
