Performance evaluation of the first commercial PUF-embedded RFID

Abstract

Physical unclonable functions (PUFs) generate device-unique data streams by using manufacturing variations of each LSI. High-security authentication for counterfeiting prevention and secret key generation for data encryption are provided through PUFs. Such technology is a recent innovation, and Verayo Inc. created the world's first commercially available PUF only a few years ago. Toppan Printing Co., Ltd., has since integrated Verayo's PUF ICs into radio frequency identification (RFID) tags in order to develop a new security business in the near field communication market. In collaboration with Toppan, we have conducted acceleration tests on their PUF-embedded RFID tag to evaluate its performance and reliability.
