Patent ID: 11963004
Assignee: PROTON WORLD INTERNATIONAL N.V.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A near field communication (NFC) router, comprising:
a memory;
a plurality of gates; and
processing circuitry coupled to the memory and the plurality of gates, wherein the processing circuitry, in operation:
configures a plurality of communication pipes between gates of the NFC router, the plurality of communication pipes including a set of communication pipes to implement NFC transactions, pipes of the set of communication pipes being coupled between radio-frequency gates of the NFC router and physical gates of the NFC router assigned to a security circuit; and
detects an attempt to use a pipe, other than one of the set of communication pipes, to implement an NFC transaction, the detecting including:
in response to receiving a message in a NFC communication format via a pipe of the plurality of pipes, comparing bits associated with the pipe with bits stored in the memory and associated with the set of communication pipes; and
in response to the comparing indicating the pipe is not one of the set of communication pipes, blocking implementation of the NFC transaction.
