METHOD FOR ESTABLISHING OTA SESSIONS BETWEEN TERMINALS AND AN OTA SERVER, CORRESPONDING OTA SERVER AND REVERSE PROXY SERVER

摘要

The invention relates in particular to a method for establishing OTA sessions between terminals and an OTA server (12) in a telecommunications network, each of the terminals interacting with a security element (10) capable of interrogating the OTA server (12) to establish a secure session in order to download data from the OTA server (12) via a reverse proxy server (11) in order to update security elements (10). According to the invention, the method comprises: provision by an OTA server (12) to reverse proxy server (11) of a list of identifiers of security elements (10) for which an update is available; only establishing a secure session between the security elements (10) and the OTA server (12) for the security elements (10) having identifiers included in said list.
