NTAG 424 DNA – Secure NFC T4T compliant IC

Leakage Resilient Primitive, or LRP – a wrapper around the AES cryptography to

enhance side-channel attack resistance.

Thanks to its high input capacitance of 50 pF, NTAG 424 DNA tag IC is well suited for

smart product applications requiring smaller footprint antennas, without compromise

on performance. Smaller NFC tags can more easily be embedded in product labels,

modules, caps and closures, and other packaging formats.

2 Features and benefits

2.1 RF Interface & Communication Protocol

• Fully compliant to the NFC Forum Tag 4 Type technical specification [15]

• Fully compliant to NDEF data structure configurations [16]

• Contactless interface compliant to ISO/IEC 14443A-2/ -3/ -4, see [1] , [2], [3]

• Support of ISO/IEC 7816-4 communication frames for highest interoperability with

mobile and wearables

• Low power consumption (Hmin) enabling operating distances of up to 10 cm

• Support of fast data rates: 106 kbit/s, 212 kbit/s, 424 kbit/s, and 848 kbit/s

• Support of double size (7-byte) Unique Identifiers (UID) and optionally Random ID

(RID) according to ISO 14443-3 [2]

• Communication frame size to support up to 128 bytes

• Support of ISO 7816-4 wrapped commands

2.2 Memory Organization

• 416 bytes user memory

• Data retention of 50 years and write endurance of minimum 200.000 cycles

• File system compliant to ISO/IEC 7816-4 with one predefined Directory File (DF) and a

set of Elementary Files (EF)

– Three standard data files, one with 32 byte for the capability file, one with 256 bytes

for NDEF storage and one with 128 bytes for protected data

• File system compliant with ISO 7816

2.3 Security and Privacy

• Common Criteria certification: EAL4 for both Hardware and Software

• Secure Unique NFC (SUN) message featuring integrity protection, authenticity and

confidentiality

• The SUN feature is enabled by the Secure Dynamic Messaging (SDM) which is

mirrored as text (ASCII encoded) into the NDEF message

• Incremental NFC Counter, which counts each tap

• Secure messaging compliant to standard AES according to NIST Special Publication

800-38A and 800-38B [5] [6]

– Optional enhanced side channel attack protection using LRP wrapped AES operation

according to [10]

• Five customer defined AES 128-bit keys including key versions

• Optional Random ID for enhanced privacy

• 3-pass mutual authentication
