Abstract

Delay-based physical unclonable function (PUF) designs use the random delay differences in circuit transmission to extract response. In the existing PUF designs, there are few studies on investigating the link between process variation
and PUF performance. The experimental data can reflect the performance of the new design to a certain extent, but lack of theoretical analysis to provide thorough information. In this paper, a theoretical model for delay-based PUF designs is proposed. An analysis of the delay-based PUF improvements by existing design strategies is also investigated. Moreover, a guidance to develop and improve future delay-based PUF designs using the proposed theoretical model is also given in this paper.
