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

? Flexible access control configurable per file (EF)

– Individual key configuration for Read (R) / Write (W) / ReadWrite (RW) / Configuration

? Configurable secure messaging communication mode

– Plain communication

– CMAC protected for message integrity protection

– Full Enciphered plus CMAC for full encryption of complete data transferred through

contactless interface

? ECC-based NXP originality signature

? AES-based originality keys leveraging the LRP wrapped AES authentication

Specific Features

? Tamper detection and secure mirroring into the NDEF message

? Frame-level oriented automatic anti-tearing mechanism

? High input capacitance (50 pF) for small form factor design

Applications

NTAG 424 DNA TT offers multi-layered security to enable a broad range of trusted

applications that protect products, services and user experiences.

? Advanced anti-counterfeiting

Verify authenticity of physical goods and identify sales outside authorized markets

? Tamper detection and proof

Detect unauthorized product opening to secure product integrity

? Secured exclusive user experiences based on product status

Enabled advanced user interactions, pre- and post-sale. Also reward customers with

truly exclusive and personalized content, offers and privileges

? Secured sensitive data applications

Protect sensitive product and user data, or trigger an action upon a verified incidence,

e.g., payment

? Secure authentication and configuration of closed loop devices

Authenticate consumables and parts, enable an integrity check, and automatically

transfer device settings
