Record type: Conference or Workshop Item (Paper)


Physical Unclonable Functions (PUF) is a promising
technology towards a comprehensive security protection for integrated circuits application. Its provide a secure method of hardware identification and authentication by exploiting inherent manufacturing process variations to generate a unique response. However, most of the proposed PUFs have been shown to be vulnerable to the attacks especially machine learning (ML) based modeling attack. This defeat the purpose of the PUF itself
which supposed to be reliable and secure. In this paper, a new
architecture of PUF which based on non-linearity dependence of
current and voltage behavior of MOSFET in sub-threshold region
is proposed. The fundamental idea is to exploit the Random
Dopant Fluctuation (RDF) effect to induce the threshold voltage
variations in the transistor operated in sub-threshold region. As
the threshold voltage varies, strong non-linearity is introduced
into the challenge-response relationship. The proposed PUF shows
excellent quality properties. The average inter-chip hamming
distance is 50.23%. The reliability over the temperature and
?10% supply voltage fluctuations is 91.58%.
