Smart card IC elevates NFC security

MIFARE DOUX, NXP’s contactless near-field communication (NFC) chip, integrates asymmetric and symmetric cryptography in one IC to simplify key management and distribution. The smart card IC enhances security for EV charging authentication, vehicle access, and other access management applications.

Leveraging public-key infrastructure (PKI), the chip supports asymmetric elliptic curve cryptography (ECC) and symmetric AES-256 cryptography. Additional features include a proximity check to counter relay attacks and transaction signatures to validate NFC transaction authenticity.

MIFARE DUOX holds Common Criteria EAL 6+ certification for both hardware and software, making it well-suited for high-security applications. Built for demanding environments, including outdoor and automotive use, it complies with ISO/SAE 21434 and MISRA-C standards and operates across an extended temperature range of -40°C to +105°C.

The MIFARE DUOX contactless smart card IC is now available.
