Protection of a security module in a telecommunication device coupled to an NFC circuit
First Claim
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.

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.

12. A telecommunication device, comprising:
-
a security circuit, which, in operation, stores data; a near field communication (NFC) router coupled to the security circuit, the NFC router having a plurality of individually assignable gates, each individually assignable gate being a physical gate; and a memory, which, in operation, stores a routing table defining linking assignments of individual ones of the plurality of individually assignable gates of the NFC router, wherein the telecommunication device, in operation; in response to receiving a request to assign a communication pipe to one of the individually assignable gates, creates and stores 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, creates a current signature corresponding to the request to provide data; verifies whether the current signature corresponds to the stored reference signature; and prevents a provision of the requested data from the security circuit in response to a failure to verify that the current signature corresponds to the stored reference signature. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A telecommunication device comprising:
-
near field communication (NFC) routing circuitry having an associated routing table to store assignments of individually assignable gates of the NFC routing circuitry; and security circuitry having a memory to store data, wherein the security circuitry, in operation, prevents transfer of data stored in the security circuitry absent verification of a current signature of the routing table, wherein the verification is a joint operation performed using both the NFC routing circuitry and the security circuitry, and wherein the device, in operation; in response to receiving a request to assign a communication pipe to one of the individually assignable gates, creates and stores 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 circuitry to the NFC router, creates a current signature corresponding to the request to provide data; verifies whether the current signature corresponds to the stored reference signature; and prevents a provision of the requested data from the security circuitry in response to a failure to verify that the current signature corresponds to the stored reference signature. - View Dependent Claims (22, 23, 24)

25. A telecommunication device, comprising:
-
means for routing near field communications (NFC); means for storing assignments of individually assignable gates associated with the means for routing in a routing table; and means for securing data to prevent transfer of data stored in the means for securing data absent verification of a current signature of the routing table, wherein the verification is a joint operation performed using both the means for routing and the means for securing, and wherein the verifying includes; 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; in response to receiving a request to provide data from the means for securing to the means for routing, 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 means for securing in response to a failure to verify that the current signature corresponds to the stored reference signature. - View Dependent Claims (26, 27)
