Abstract
A telecommunication device protects data stored in a security module. The device has a near field communication (NFC) router with a plurality of individually assignable gates and a routing table. In response to a request to assign a communication pipe to one of the gates, the device creates and stores a reference signature for the pipe based on at least one of a personal code of an authorized user of the device or an identifier of a radio frequency gate of the router. In response to a request to provide data from the security module to the NFC router, the device creates a current signature corresponding to the request to provide data. The device verifies whether the current signature corresponds to the stored reference signature and prevents a provision of the requested data based on a failure to verify the current signature corresponds to the stored reference signature.
