Bioinspired and Sustainable Physical Unclonable Functions with Antibacterial Microstructures

Advanced Intelligent Systems, Volume 7, Issue 11, November 2025.
An eco‐friendly physical unclonable function (PUF), named HECTA, is developed through spontaneous self‐assembly of hydroxyethyl cellulose (HEC) and tannic acid (TA), forming unique microstructures via hydrogen bonding. Exhibiting high reproducibility, ideal security metrics, and antibacterial activity, this sustainable PUF presents secure ...

Quantum Dots and Perovskites‐Based Physically Unclonable Functions for Binary and Ternary Keys via Optical‐to‐Electrical Conversion

Advanced Functional Materials, Volume 35, Issue 42, October 15, 2025.
This study investigates optoelectronic PUFs that improve on traditional optical and electrical PUFs. The absorber materials are randomly coated through spray coating, ligand exchange, and dynamic spin coating. Incident light generates wavelength‐dependent binary multikey and enhances security ternary keys, approaching near‐ideal inter‐ and intra ...
