Abstract: A near field communication (NFC) router of a telecommunication device has communication pipes between gates of the NFC router. The pipes include a set of communication pipes to implement NFC transactions, which are coupled between radio-frequency gates of the NFC router and physical gates of the NFC router assigned to a security circuit. An attempt to use a pipe, other than one of the set, to implement an NFC transaction is detected by, in response to receiving a message in a NFC communication format via a pipe, comparing bits associated with the pipe with stored bits associated with the set of communication pipes. In response to the comparing indicating the pipe is not one of the set of communication pipes, implementation of the NFC transaction is blocked.
