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 ...

Aging resilient ring oscillators for reliable Physically Unclonable Functions (PUFs)

Microelectronics Reliability
Physically Unclonable Functions (PUFs) are a promising low-cost solution for authentication and key generation in cryptosystems. However, it has been shown in the literature that, due to aging mechanisms such as Bias Temperature Instability (BTI), PUFs may no longer be able to generate correct outputs after a certain lifetime, thus becoming unreliable.
