ICs Promise Secure, Contactless Transactions in Smart-City Apps

June 5, 2020
Fast, secure contactless transactions with mobile and multi-application support enable service providers to collaborate and scale services.

Offering advanced security features and seamless integration of mobile services, NXP Semiconductors’ MIFARE DESFire EV3 IC represents the third generation of NXP’s contactless MIFARE DESFire portfolio. The latest iteration of the IC is backwards-compatible with earlier versions but offers greater operating distance and improved transaction speed. It delivers faster, more secure transactions that are truly contactless, such as paying for parking, accessing offices or campuses, and using other essential city services—all touch-free.

Building on its heritage of powering mass-transit ticketing, the MIFARE DESFire EV3 IC provides multi-application support and delivers a wide array of enhanced features that allows transit agencies, access control solution providers, and system integrators to collaborate on new business models and scale their services.

An extensive set of security features in the MIFARE DESFire EV3 IC provides more ways to protect data and help ensure privacy. The IC’s hardware and software are certified to Common Criteria EAL 5+, and the IC supports a broad choice of open crypto algorithms. A card-generated MAC helps to securely authenticate transactions, and a new Transaction Timer feature helps mitigate man-in-the-middle attack, making it harder for an attacker to interfere with the transaction. Additionally, a new Secure Unique NFC (SUN) messaging feature offers a more secure method for maintaining data confidentiality and integrity. Each time a card, phone, or ticket is tapped with the SUN featured enabled, a tap-unique authentication message and crypto-secure URL are generated that can be sent to a server for verification, which makes taps unclonable.

Support for MIFARE DESFire EV3 will be integrated into NXP’s MIFARE 2GO cloud service, which manages digitized MIFARE product-based credentials and helps streamline mobile integration via NXP’s ecosystem. With this, smart-city services can be seamlessly deployed to NFC-enabled smartphones, wearables and other mobile devices.

For simplified deployment, each MIFARE DESFire EV3 IC is pre-configured with keys to enable delegated application management, which supports seamless, over-the-air updates to already deployed smart cards using NFC-enabled smartphones.

In addition, NXP’s upcoming MIFARE Plus EV2 IC will provide a drop-in replacement for upgrading existing MIFARE Plus and MIFARE Classic product-based installations to higher security.
