NT4H2421Tx NTAG 424 DNA TT - Secure NFC T4T pliant IC with Tag Tamper feature Rev. 3.0 - 31 January 2019 Product data sheet PANY PUBLIC 1 General description 1.1 Introduction NTAG 424 DNA TT (NT4H2421Tx) sets a new standard in secure NFC and Io T applications, introducing a new NTAG DNA chip generation with state-of-the-art Features for security, status detection and privacy protection. It es with AES-128 cryptographic operation and a new Secure Unique NFC Message (SUN) feature to generate tap-unique data authentication upon each read-out by an NFC enabled mobile device. This enables most advanced product protection in terms of product authenticity and integrity, as well a secure exclusive user experiences based on product status served in real time. NTAG 424 DNA TT is fully pliant with the NFC Forum Type 4 Tag specification (Certification ID: 58569), with the contactless proximity protocol according to ISO/ IEC14443-4 and the ISO/IEC 7816-4 based file system and mand frames, to ensure maximum interoperability within the NFC infrastructure. Its NFC performance supports superior user interaction and an operating distance of up to 10 cm. Using AES-128 cryptography, the tag generates a unique NFC authentication message (SUN) each time it is being tapped. An NFC mobile device reads this tap-unique URL with the SUN authentication message, sends it to the host where tag and message authentication take place, and returns the verification result. The SUN authentication mechanism is working on Android without a dedicated application and from i OS11 onwards using an application. This way, NTAG 424 DNA TT offers tag authentication, as well as data assurances on authenticity, integrity and even confidentiality, while also securing physical tag presence, see also Section 9.3. In addition, NTAG 424 DNA TT es with smart status awareness, detecting the status of a tamper loop. Users can instantly detect the once-opened status, by just reading the...
