Physically Unclonable Functions based on Voltage Divider Arrays of MOSFETs in Subthreshold Region of Operation

In this thesis, a novel architecture of a simple, low energy silicon physically unclonable function (PUF) for the purpose of device authentication is proposed. The physically unclonable function proposed is a voltage divider array of MOSFETs operating in the subthreshold region of operation. This design aims to improve the energy efficiency when compared to the previously published designs. This structure is a strong silicon PUF with 260 challenge response pairs and consumes 0.48pJ/bit of energy only. The measured inter hamming distance is 0.4982 and intra hamming distance is 0.0225. The circuits are designed in TSMC 65nm technology using Cadence software and the computations and interpretations is done using MATLAB.
