NXP integrates AES with EAL3+ for secure contactless MiFare

Claimed to be the most secure member of the MiFare Ultralight family, NXP Semiconductors has integrated Advanced Encryption Standard (AES) with Common Criteria EAL3+ security certification to enhance privacy and security in limited-use contactless tickets, RFID basic guest cards and other limited-use contactless applications.

MiFare Ultralight AES is for limited-use contactless tickets and cards, such as RFID basic guest cards, event tickets, access passes, loyalty cards or transit tickets. IT uses cryptography with sufficient key length recommended by the National Institute of Standards and Technology for secure authentication and protected data access and there is the option to limit negative authentication attempts. 

The ICs offer protected data access based on AES authentication with 128-bit key length and optional Command Counter to limit negative authentication attempts. They also have a configurable secure messaging communication mode with CMAC for integrity protection and a 7-byte UID with optional Random ID support for enhanced privacy. An ECC-based originality signature allows product validation based on public key (pre-programmed). The ICs include a 144-byte EEPROM and are ISO / IEC 14443 A -2 / -3 compliant.

The secure implementation is suitable for guest protection and secure room access or as a secure transport ticket in smart cities.  

Andre Perchthaler, segment manager, MiFare Smart Cities, at NXP, said: “By taking advantage of a single, standard-based encryption method, such as AES, service providers have the benefit of greater fraud prevention, while also being able to streamline integration and key management. With MiFare Ultralight AES, the full MiFare product portfolio now serves AES authentication from single-use up through multi-applications, simplifying access infrastructure, and reducing complexity and maintenance costs.”  

NXP Semiconductors claims to be the world leader in secure connectivity solutions for embedded applications, NXP is pushing boundaries in the automotive, industrial and IoT, mobile, and communication infrastructure markets.
