MIFARE DUOX, the first NFC contactless integrated circuit (IC) in its class to integrate symmetric and asymmetric cryptography into a single product, was unveiled by NXP Semiconductors. By lowering the complexity of key management and key distribution, this aids in the simplification of security for NFC applications, including secure auto access, electric vehicle (EV) charging authentication, and other access management applications. High-performing, extremely secure, and reasonably priced NFC system solutions are made possible by the combination of improved security, asymmetric authentication, and sophisticated functionality.
NFC-enabled applications, which offer practical tap-to-access features, are becoming more and more important in smart cities. Applications for MIFARE DUOX are numerous and include corporate access control systems, secure vehicle entry, and EV charging. Using the public key infrastructure (PKI) principle, MIFARE DUOX integrates symmetric and asymmetric encryption to greatly simplify key distribution and administration.
“We’re allowing the industry to simplify key distribution and management in rapidly expanding verticals like EV charging authentication or secure car access, without sacrificing contactless transaction speed or product versatility,” stated André Perchthaler, Senior Director, MIFARE, NXP. “MIFARE DUOX offers cost-effectiveness and high security along with new features and flexible configuration options and settings to support more flexible NFC system solutions.”
MIFARE DUOX integrates symmetric and asymmetric cryptography, combining symmetric AES-256 cryptography technology and asymmetric elliptic curve cryptography (ECC), to streamline and expand key management and distribution flexibility. Additionally, it has improved security features including Transaction Signature to verify the legitimacy of completed NFC transactions and Proximity Check to stop relay attacks.
True multi-application and multi-purpose use scenarios are made possible by MIFARE DUOX’s adaptable file system design. Installing an application after issuance on a single IC across numerous card issuers and service providers is also included in this.
End users will have more convenience because they just need to carry one NFC-enabled MIFARE DUOX smartcard in their pocket, which houses numerous applications on a single device, including corporate access, EV charging, user authorization, reward programs, and many more.
