NFC and RFID tech are more familiar than ever with the isolated and socially distancing lifestyle. Facing initial security issues and some heated discourse about the technology’s data security, RFID has stayed a quite common technology.
Stock level, production lines, and delivery monitoring applications are good fits for RFID because of their ability to locate tags, whether passively at close range or with an active power source over ranges up to 100 meters. With this range comes concerns regarding RFID protection and privacy, though some claim that these concerns have been resolved or are largely unfounded.
NFC has seen rapid adoption of mobile applications in recent years, perhaps most notably in digital payments like Apple Pay and Android Pay.
NFC devices can serve as both a reader and a tag, and interactions take place over a short range of a few cm instead of the long-range RFID. This close-range provides an extra layer of protection since intercepting correspondence within centimeters among devices is extremely difficult.
Although there are still several issues concerning NFC privacy and protection, programmers are actively working to fix them.
NXP’s NTAG 424 DNA in detail
In safe NFC and IoT applications, NTAG 424 DNA represents a new norm. On attack-resistant validated chips, the latest silicon chip generation provides features for security and privacy protection.
The NTAG 424 DNA is designed to provide AES-128 cryptographic operation, a new SUN encryption protocol on every NFC-enabled smartphone, and critical data security via crypto-secure user credentials. This allows for the almost highest possible product and content security and safe and exclusive real-time mobile applications.
The NTAG 424 DNA TagTamper labels provide another innovation. It allows even more personalized interactions by giving customers status-aware, appropriate customer notifications once the tag’s sealing on a product or container is opened or damaged.
The 424 DNA TagTamper, as well as the unique technology NTAG 424 DNA, are started to be offered to customers.
The most important aspect is encryption technology
AES-128 encryption is used by NTAG 424 DNA, a world government protocol for sensitive information. It also includes the AES-128 leak recovery raw (LRP) layer, which brings extra software layers to cover the tag’s information.
Authentication concerns mostly covered with NTAG 424 DNA
Authentication notifications will be sent in encrypted data using the tag’s Secure Unique NFC (SUN) authentication services. Each tapping generates a new SUN utilizing AES-128 cryptography. The specific URL with the SUN code is read by the NFC reader and sent to the database. The server authenticates the request and tag, and the response is returned to the NFC reader.
EdgeLock Assurance Certification
The NTAG 424 DNA as well as NTAG 424 DNA TagTamper, which are a member of the Certified EdgeLock Certification scheme, are established to achieve industry requirements and adhere to NXP’s security-by-design philosophy. An independent lab has accredited them. So the company offers a new level of security with proofs.
We are not giving up on staying connected and the benefits of incorporating IoT into our everyday lives. However, users are aware that certain privacy and security concerns, like others, could affect them one day. As a result, hardware solutions such as the NTAG 424 DNA for NFC technology and NFC enabled devices can play a vital role in establishing customer trust.
