Abstract

For the first time, the negative-bias-temperature-instability (NBTI) enhanced drain current variation in FinFET is used as an entropy source of the Physical Unclonable Function (PUF) to realize a new NBTI-PUF. The results show that the higher-temperature NBTI stress applied on the PUF, a much better security of the PUFs can be achieved, including 46% improvement of Inter Hamming Distance (HD), 71% improvement of Intra-HD, 40% improvement of Hamming Weight, and 15-fold-decrease of Bit-error-rate. Furthermore, the NBTI-PUFs have passed 13 items of NIST tests under 150°C.
