RAIN RFID tag has built-in cryptographic security, long read range

April 21, 2015 // By Susan Nordyk, EDN
NXP Semiconductors’ UCODE DNA is one of the first UHF RAIN RFID tags to combine long-range read performance with cryptographic authentication, giving developers contactless performance and security in a single IC.

The tag IC can be used in a wide variety of applications, such as electronic road tolling, electronic vehicle registration, license plate authentication, access control, asset tracking, brand protection, and special service offerings at large-scale venues.

Cryptographic authentication provides dynamic security with each transmission being different from the one before, minimising the ability for data to be emulated. The UCODE DNA delivers ISO/IEC 29167-10 standardised cryptographic security using a 128-bit key based on AES (advanced encryption standard) algorithms. It is also compliant with the GS1 EPC Gen 2 V2 air interface standard, which supports cryptographic authentication in RFID systems operating in the UHF range (860 MHz to 960 MHz).

NXP Semiconductors offers developers a service for trust provisioning, which generates and inserts the cryptographic keys into the UCODE DNA tag IC during the manufacturing process. In addition, the device provides up to 3 kbits of user memory with block permalock, up to 448 bits of EPC (electronic product code) memory, and read sensitivity of -19 dBm.

The RAIN RFID Alliance promotes awareness, education, and initiatives to accelerate the adoption in business and consumer applications worldwide of passive UHF RFID standards developed by GS1 and incorporated by ISO/IEC. RAIN products include readers, tags, software, data, and services.

A datasheet for the UCODE DNA was not available at the time of this announcement.
