A Reconfigurable SRAM Based CMOS PUF With Challenge to Response Pairs

IEEE Access, 2021
This paper presents a reconfigurable SRAM-based physically unclonable function (PUF) topology with multiple challenge-response pairs (CRPs) per cell. The proposed PUF structure enables a very large CRP space by connecting additional pull-up and pull-down

Biological physically unclonable function [PDF]

Communications Physics, 2019
AbstractInformation security is one of the foundational requirements for any modern society thriving on digital connectivity. At present, information security is accomplished either through software algorithms or hardware protocols. Software algorithms use pseudo random numbers generated by one-way mathematical functions that are computationally robust

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.

Self-Timed Physically Unclonable Functions

2012 5th International Conference on New Technologies, Mobility and Security (NTMS), 2012
Physically unclonable functions (PUFs) exploit the physical characteristics of silicon and provide an alternative to storing digital encryption keys in non-volatile memory. In this seminal work, I propose for the first time the use of self-timed logic to implement PUFs.

Programmable In‐Situ Interactions Between Resins and Photopolymerized Structures for Seamlessly Integrated Optical Manufacturing of Microlenses

Advanced Functional Materials, EarlyView.
This study presents a dynamic interaction between liquid resins and photopolymerized structures enabled by an in situ light‐writing setup. By controlling a three‐phase interface through localized photopolymerization, which provides physical confinement for the remaining uncured resin regions, the approach establishes a programmable pathway that ...
