PROTECTION OF A COMMUNICATION CHANNEL OF A TELECOMMUNICATION DEVICE COUPLED TO AN NFC CIRCUIT AGAINST MISROUTING

摘要

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.
