Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.

Weak Physycally Unclonable Functions in CMOS Technology: A Review
ChipsPhysically unclonable functions (PUFs) represent emerging cryptographic primitives that exploit the uncertainty of the CMOS manufacturing process as an entropy source for generating unique, random and stable keys. These devices can be potentially used in

Physical Unclonable Function [PDF]
, 2019 A Physical Unclonable Function (PUF) is hardware that acts as a one-way function, whose each different instance provides unique outputs for the same distinct input. Although recent research has demonstrated the merits of PUFs as security primitives for resource-constrained computer systems, better implementations of them need to be identified ...

Silicon photonic physical unclonable function
Optics Express, 2017 Physical unclonable functions (PUFs) serve as a hardware source of private information that cannot be duplicated and have applications in hardware integrity and information security. Here we demonstrate a photonic PUF based on ultrafast nonlinear optical interactions in a chaotic silicon micro-cavity.

Computational optical physical unclonable functions
2017 International Carnahan Conference on Security Technology (ICCST), 2017 Physical unclonable functions (PUFs) are devices which are easily probed but difficult to predict. Optical PUFs have been discussed within the literature, with traditional optical PUFs typically using spatial light modulators, coherent illumination, and scattering volumes; however, these systems can be large, expensive, and difficult to maintain ...
