NTAG 413 DNA encryption

Hi there,

In our project we're trying to implement visit control using NXP NTAG 413 DNA.


We need the following algorithm:

User taps the tag with his mobile device. When tapped, mobile device software (which we'll develop) writes current date time to tag, and then immidiately gets it back encrypted (or CMACed). In other words, we need to encrypt or CMAC our custom data (eg. current date time) + chip UID. Is it possible to implement with NTAG 413 DNA?


Kind regards,
