RFID tag offers secure authentication


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, minimizing the ability for data to be emulated. The UCODE DNA delivers ISO/IEC 29167-10 standardized 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.
