Protection against rerouting in an NFC circuit communication channel

摘要

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.

1. A method to protect data stored in a security module of a telecommunication device equipped with a near field communication (NFC) router, comprising:
storing at least one pipe identifier in a routing table between gates of said NFC router, said at least one pipe identifier calculated according to an identifier of a radio frequency gate of a near field communication circuit associated with the router; and prohibiting access to the data stored in the security module when the at east one pipe identifier is absent.
