I am designing with NXP's PN7120 NFC controller chip. I was curious about security and encryption options. I looked through the NXP presentation "Security in NFC Readers" which talks about using SAM (Secure Access Module) module for security. I read through the PN7120 datasheet and it does not mention anything about having an integrated SAM module. My objectives are:-
1)To ensure unauthorized tags do not communicate with my NFC reader/controller
2)To protect my NFC tag's content from being read by an unauthorized NFC reader
The questions then become:
-Does the PN7120 not contain an integrated SAM module?
-What would then be my options to secure communication with tags e.g. NTAG216?
-Is there a way to make tags unreadable by unauthorized NFC readers/controllers? i.e. can I protect/encrypt my tag's content from being read by other readers?
