Abstract: A method to attach a mobile device to a server, using a protocol having data size encoding constraints which prevents using traditional ciphering, includes an initialization phase using a range of ephemeral IMSIs stored in a batch of credential containers of mobile devices and an associated group master key shared by the server and credential containers having the same range of ephemeral IMSIs to initiate a session using a server random value. The initialization phase uses limited payload in a mobile device-to-server message to send a randomly chosen rIMSI among the range of IMSIs to enable the server to generate keys to initiate a secured communication phase, then using individual keys stored in the mobile device and retrieved by the server with an identifier of the credential container sent in a mobile device-to-server message and with an individualization master key owned by the server.

Abstract: A method for personalizing pre-generated protected profiles, as defined by the GSMA SGP.02 and SGP.22 RSP Technical Specifications, includes adding an application and diversified data at the end of the profiles in order to re-compute only the SCP03t security at the end of the profiles and to transmit the protected profiles to eUICCs cooperating with terminals.

Abstract: Content data available in a server is downloaded to portable communicating objects via a radio communication network during a data downloading campaign initiated by a portable communicating object upon transmission of a request of content availability to the server when at least one request transmission triggering element fulfills a rule stored in the portable communicating object. Upon reception of the content availability request, one of the devices including the server and the portable communicating object determines whether the content data are available for the portable communicating object so as to transmit the same thereto.
