Abstract: A central server for communicating with a user equipment and a cellular network is provided. The server is configured to exchange with the cellular network information relating to at least one preconfigured qualifier assigned to the user equipment and assigned to the central server. The server receives a payload item from the cellular network transmitted by the user equipment to said cellular network by means of an authentication failure message for authenticating a user equipment at a cellular network during an attach comprising the payload item, instead of receiving a SMS or establishing an IP connection with the user equipment. The payload item can result from a latest measurement data of user equipment regularly transmitting data to said central server and/or a sensor connectively coupled to the user equipment when operating as an Internet of Things (IoT) smart-metering device.

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.
