Abstract

In this paper, we propose a new Delay PUF architecture trying to solve the major problem of existing Delay PUFs that it is easy to predict the relation between delay information and generated information. For that purpose, our architecture exploits glitches as a source of information generation that behave non-linearly from delay variation between gates and the characteristic of pulse propagation of each gate. We thus call it the Glitch PUF. We present two circuit structures of the Glitch PUF both of which have their own merits. We then provide the results of evaluation in which we first verify that the two Glitch PUFs exhibit the same characteristics, and second show the randomness and statistical properties of the Glitch PUF.
