Abstract
(EN)
In overview, a computer-implemented method of transmitting data in a data stream from a first device to a second device is disclosed. The data stream is encrypted before transmission from the first device to the second device, and a location of the data in the data stream is indicated to the second device. The location may be a pre-shared location between the first and second devices, or the first device may transmit the location of the data to the second device. The second device decrypts the encrypted data stream, identifies the data in the data stream based on the location, and encrypts the identified data in the data stream.

De manière générale, l'invention concerne un procédé mis en œuvre par ordinateur de transmission de données dans un flux de données depuis un premier dispositif vers un second dispositif. Le flux de données est chiffré avant la transmission depuis le premier dispositif vers le second dispositif, et un emplacement des données dans le flux de données est indiqué au second dispositif. L'emplacement peut être un emplacement pré-partagé entre les premier et second dispositifs, ou le premier dispositif peut transmettre l'emplacement des données au second dispositif. Le second dispositif décrypte le flux de données chiffrées, identifie les données dans le flux de données sur la base de l'emplacement, et chiffre les données identifiées dans le flux de données.
