The thesis work 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 2^60 challenge response pairs. This work consumes a very low energy of 0.48pJ/bit. The PUF is designed in TSMC 65nm technology and has a normalized inter HD of 0.4982 and intra HD of 0.0225.
