Public Physical Unclonable Functions
Proceedings of the IEEE, 2014 A physical unclonable function (PUF) is an integrated circuit (IC) that serves as a hardware security primitive due to its complexity and the unpredictability between its outputs and the applied inputs. PUFs have received a great deal of research interest and significant commercial activity.

Physical Unclonable Functions: A Primer
IEEE Security & Privacy, 2014 Physical unclonable functions (PUFs) make use of the measurable intrinsic randomness of physical systems to establish signatures for those systems. PUFs provide a means to generate unique keys that don't need to be stored in nonvolatile memory, and they offer exciting opportunities for new authentication and supply chain security technologies.

An Asymmetric Optical Cryptosystem Using Physically Unclonable Functions in the Fresnel Domain
Engineering Proceedings, 2023 In this paper, we propose a new asymmetric cryptosystem for phase image encryption, using the physically unclonable functions (PUFs) as security keys. For encryption, the original amplitude image is first converted into a phase image and modulated with a

Quantifying the Sensitivity and Unclonability of Optical Physical Unclonable Functions
Advanced Photonics Research, 2022 Due to their unmatched entropy, complexity, and security level, optical physical unclonable functions (PUFs) currently receive a lot of interest in the literature. Despite the large body of existing works, herein, one of their core features in detail is studied, namely, their physical unclonability. This article tackles this fundamental and yet largely

Modeling attacks on physical unclonable functions [PDF]
Proceedings of the 17th ACM conference on Computer and communications security, 2010 We show in this paper how several proposed Physical Unclonable Functions (PUFs) can be broken by numerical modeling attacks. Given a set of challenge-response pairs (CRPs) of a PUF, our attacks construct a computer algorithm which behaves indistinguishably from the original PUF on almost all CRPs.
