Photonic Side-Channel Analysis

Abstract

In this chapter, we demonstrate that the primary security assumption on the infeasibility of direct delay measurements in delay-based PUFs is not valid. By performing an experiment on a PoC Arbiter PUF implementation on reconfigurable hardware, it becomes apparent that The Arbiter PUF family and more generally, the delay-based PUFs can be characterized by a high-resolution temporal photonic emission analysis. This approach does require neither any access to the PUF’s response nor a significant number of challenges to characterizing the PUF.
