NXP introduced NTAG® 424 DNA TT, a new NFC tag and label chip that extended high-level security, data detection & privacy protection for NFC and IoT authentication applications.
Introduction To NTAG® 424 DNA TagTamper
NTAG® 424 DNA TT supports AES 128 encryption for authentication/ secure messaging identified as cloud authentication services. It supports cryptographic operations & secure Unique NFC message SUN by NFC enabled iOS or Android mobile devices for data authenticity & product authenticity & integrity.
It is fully compliant with NFC forum type 4 tag specification & ensures maximum interoperability within NFC infrastructure & contactless proximity up to 10 cm.
The memory structure of the chip comprises 416 bytes, which are fully compliant with NFC Forum Type 4 Tag.
The random operational ID together with encrypted chip UID /data maintains data privacy, compliance with the user’s data protection regulations.
NTAG® DNA TAG chip attack resistant tools that have the potential to fight against fraud, IP theft & data breaches & tampering.
Thus, NTAG® 424 DNA Introduced a secure dynamic messaging feature enabled with NFC mobile phones at each tap. The “tap unique” NDEF message offers to the backend system (e.g. cloud) a unique tag identifying.
NTAG 424 DNA offers five special security features
The NTAG 424 DNA TagTamper offers enhanced security features, that AES 128 based encryption with five consumer defined keys.
HIGH-LEVEL STORAGE SECURITY
According to the Gemalto, breach level index report, an estimated over 9 billion data records have been lost or stolen worldwide since 2013 due to cybercrime.
NTAG 424 DNA initiates secure encrypted communication between tag to reader and the server. It only permits authorized users, applications, and devices to sensitive data.
SUN MESSAGE AUTHENTICATION
NTAG 424 DNA tag generates a secure Unique NFC SUN authentication message using AES 128 cryptography. An NFC enabled device reads the tap unique URL with its crypto secure SUN code, and then sends it to the server for authentication. And returns the verification result. The SUN mechanism is compatible with all NFC enabled phones to offer data confidentiality and integrity.
USER PRIVACY DATA REGULATIONS
On-chip features protect users’ privacy data via random ID and encrypted SUN UID data let NTAG 424 DNA tags to ensure data privacy which is compliance with the latest privacy regulations of the jurisdiction.
OPTIONAL TAMPER PROTECTION
The NTAG® 424 DNA TAG tamper including the tamper loop with optional tamper protection can detect the tag seals to confirm the product integrity.
VALUE- ADDED SERVICES
Chips enabled optional value-added services; trust provisioning services of chip individual AES keys enhance entire system security.
