Abstract: A method for protecting information contained in a security module of a telecommunication device provided with a near-field communication router, wherein a routing table between the ports of the router contains at least one channel identifier calculated from an identifier of a radiofrequency port of a near-field communication circuit associated with the router.

Abstract: A method for protecting data contained in a security module of a telecommunication device equipped with a near-field communication router and with a microcontroller, wherein data relative to the routing between the security module and gates of the router assigned to near-field communications are transmitted over a channel accessible by the router only, or by a control signal which is not generated by the microcontroller for the router.

Abstract: A processing device of an NFC device receives a request, initiated by a first application loaded in a memory of the NFC device, to modify one or more parameters of an NFC routing table of an NFC router of the NFC device. The NFC routing table has parameters indicating the devices to which NFC messages are to be routed. The processing device retrieves a first identifier associated with the application and transmits the first identifier to the NFC router. The NFC router, based on the first identifier, verifies whether or not the application is authorized to modify the routing table.

Abstract: A near field communication (NFC) router of a mobile device receives a first message from an external NFC device and, in accordance with a first active rule, processes the first message as being targeted to a first host processing device of the mobile device. When the NFC router receives a second message from the external NFC device and detects a bit pattern in the second message indicating that the first host processing device is not an intended target of the second message, the NFC router activates a second rule. When the NFC router receives a further first message from the external NFC device, the NFC router processes the further first message as being targeted to a target host processing device in accordance with the second active rule.

Abstract: The implementation of a counter in a microcontroller adapted to the JavaCard language while respecting the atomicity of a modification of the value of this counter, wherein the counter is reset by the sending to the microcontroller of an instruction to verify a user code by submitting a correct code, and the value of the counter is decremented by the sending to the microcontroller of the instruction to verify the user code with an erroneous code value.

Abstract: A method for configuring a first device for a near-field communication with a second device, wherein a peer-to-peer mode is selected if the second device draws the power supply of its circuits from a battery.

Abstract: The invention relates to a method of protecting a security module (14) equipping a telecommunication device equipped with a near-field communication router (18), against an attempt to divert a channel for communication between a port of this security module and a port of the router, in which upon each request originating from the router and destined for the security module, the latter verifies the rights of access to the information that it contains as a function of the provenance of the request.

Abstract: A method for assessing the resistance of a security module against an attempt to divert a communication pipe between a gate of this security module and a gate of a near-field communication router present in a telecommunication device to which the security module is intended to be connected, including the steps of: connecting the security module to a near-field communication router emulator; having the emulator send at least one command to the security module, this command simulating the fact that the pipe used is not connected to a near-field communication gate; and determining whether the security module accepts the commands.

Abstract: A method for detecting an attempt of diversion of a communication pipe between a port of a security module and a port of a near-field communication router present in a telecommunication device, wherein the router filters the messages addressed to said security module.

Abstract: A method for protecting data contained in a security module of a telecommunication device equipped with a near field communication router, wherein a modification of a routing table between gates of the router is dependent on a verification of an authentication code keyed in by a user.

Abstract: The invention relates to a method for detecting an attempt to reroute a communication channel between a port of a security module and a port of a near-field communication router, which are in a telecommunication device, wherein, upon receiving a message in a near-field communication format, the security module verifies from which port of the communication router said message originates.
