2.3.3.2 NFC Counter
A 3-byte up counter is incremented only once per each session when the NDEF file is
read. This counter value can be optionally mirrored in plain into the NDEF message.
Counter value can be read out encrypted after authentication by using the assigned
application key as well.
2.3.3.3 CMAC
The 8-byte CMAC can be optionally mirrored into the NDEF message. CMAC is
calculated on the defined message length. It is possible to consider only the UID and/or
the NFC Counter for CMAC calculation.
2.3.4 Mutual authentication
NTAG 413 DNA offers 3-pass mutual authentication based on challenge response
protocol with the application key. This mutual authentication enables the authentication of
the tag and host ( who knows the keys) simultaneously.
2.3.5 ECC signature
NTAG 413 DNA offers a static ECC signature calculated on the UID of the chip. This
ECC signature can be used to verify the tag's genuineness using the public key provided
by NXP [8].
2.3.6 Ultimate product authentication
NTAG 413 DNA features can be integrated to design a robust product authentication.
Concatenating of the multiple features e.g. ECC signature, history based UID tracking,
SUN and 3-pass mutual authentication to design enhanced reliability in product
authentication.
2.3.7 Customization from fab
NXP offers commercially the customization of the chip content (securely key injection
known as trust provisioning, personalization of NDEF message and file settings). Refer to
[13] for detail.
3 Applications
NTAG 413 DNA has been designed to fit in many NFC tagging applications, particularly
where security is required. Several applications (but not limited) are mentioned below:
• Web-based product authentication without any application installed in NFC reader
device
• In general product authentication with application installed in NFC reader device
• Access management (logical & Physical)
• Electronic voucher
• Gaming
• Consumer interaction
