Abstract

In this paper we propose a new Delay-PUF architecture that is expected to solve the current problem of Delay-PUF that it is easy to predict the relation between delay information and generated information. Our architecture exploits glitches that behave non-linearly from delay variation between gates and the characteristic of pulse propagation of each gate. We call this architecture Glitch PUF. In this paper, we present a concrete structure of Glitch PUF. We then show the evaluation results on the randomness and statistical properties of Glitch PUF. In addition, we present a simple scheme to evaluate Delay-PUFs by simulation at the design stage. We show the consistency of the evaluation results for real chips and those by simulation for Glitch PUF.
