1. A non-transitory computer-readable medium having contents which configure a telecommunication device to protect data stored in a security module of the telecommunication device, the telecommunication device having a near field communication (NFC) router, the NFC router having a plurality of individually assignable gates and a routing table, the protecting including:

  • in response to receiving a request to assign a communication pipe to one of the individually assignable gates, creating and storing a reference signature for the communication pipe based on at least one of a personal code of an authorized user of the telecommunication device or an identifier of a radio frequency gate of the router;

    in response to receiving a request to provide data from the security module to the NFC router, creating a current signature corresponding to the request to provide data;

    verifying whether the current signature corresponds to the stored reference signature; and

    preventing a provision of the requested data from the security module based on a failure to verify that the current signature corresponds to the stored reference signature.
