Modeling of physical unclonable functions (PUF): A systematic literature review

This academic paper is a systematic literature review (a comprehensive analysis of existing research) about physical unclonable functions, or PUFs, which are hardware-based security features that create unique, unchangeable identifiers for devices based on their physical properties. Published in July 2026, the review examines how PUFs are modeled and studied across different research papers. The paper does not describe a security problem or vulnerability, but rather surveys current knowledge about how these security devices work.
