Abstract: A method for establishing OTA sessions between terminals and an OTA server in a telecommunications network, each of the terminals interacting with a security element capable of interrogating the OTA server to establish a secure session in order to download data from the OTA server via a reverse proxy server in order to update security elements. The method includes provision by an OTA server to reverse proxy server of a list of identifiers of security elements for which an update is available; only establishing a secure session between the security elements and the OTA server for the security elements having identifiers included in said list.

Abstract: The invention relates to a method for communicating information. A first device is coupled to a secure element. The secure element sends, at an initiative of the secure element, to the first device a secure element identifier. The first device sends to a second device at least one first message comprising the secure element identifier. The second device sends to a third device at least one second message comprising the secure element identifier and two communication network subscription identifiers, as associated data, the second device adding the two communication network subscription identifiers. The third device stores the associated data. The invention also relates to a corresponding system.
