This paper proposes a novel architecture of a simple, low energy silicon physically unclonable function arrays depending on the large random variation of threshold voltage of MOSFETs operating in subthreshold region. The proposed structure is a strong silicon PUF with 260challenge response pairs and consumes an energy of 0.48pJ/bit. The PUF is simulated in 65nm CMOS technology and has a normalized inter-HD of 0.4982 and intra-HD of 0.0225.
