Authentication module

A remote device arranged to communicate with a handling server, the remote device comprising:

• an authentication module for the remote device using authentication according to a mobile telephony standard, wherein the authentication module is stored on a storage medium of the remote device and comprises an IMSI, a secret key, an alternate serial communications module, and authentication algorithms for carrying out, by the remote device, authentication and key generation according to the mobile telephony standard using at least the secret key;
• and
• a processor connected to the authentication module, wherein the authentication module further comprises a serial input/output module configured to connect to a cellular modem, and wherein the alternate serial communications module provides a communication key to an application layer running in the processor that connects to a wireless module,
• wherein the processor contains code for accessing the authentication module and that, when executed by the processor, configures the processor to use said authentication algorithms for encrypting, at a non-physical layer, communications from the processor over a physical transport structure to the handling server to provide end-to-end encryption for communication with the handling server independently of the physical transport structure used.
