MIFARE® DESFire® EV3: High-Security IC for Contactless Smart City Services

2023-10-26 View:

The features of the MIFARE DESFire EV3 IC reflect NXP’s continued commitment to secure, connected and convenient contactless Smart City services. As part of the MIFARE DESFire family, the latest family member combines enhanced performance with a greater operating distance and improved transaction speed compared to its predecessors, including:
- IC hardware and software certification according to Common Criteria EAL 5+
- Broad choice of open crypto algorithms based on DES, 2K3DES, 3K3DES, or AES
- SUN message authentication for advanced data protection
- Transaction Timer to mitigate man-in-the-middle attacks

- Seamless integration of mobile services in combination with MIFARE 2GO
