Title:
Security Analysis of Delay-Based Strong PUFs with Multiple Delay Lines

Authors: Anita Aghaie, Amir Moradi, Johannes Tobisch, Nils Wisiol

Abstract:

Using a novel circuit design, we investigate if the
modeling-resistance of delay-based, CMOS-compatible strong
PUFs can be increased by the usage of multiple delay lines.
Studying a circuit inspired by the Arbiter PUF, but using four
instead of merely two delay lines, we obtain evidence showing
that the usage of many delay lines does not significantly increase
the security of the strong PUF circuit. Based on our findings, we
suggest future research directions.
