Dynamic Physically Unclonable Functions [PDF]

Proceedings of the 2019 Great Lakes Symposium on VLSI, 2019
Physical variations in the manufacturing processes of electronic devices have been widely leveraged to design Physically Unclonable Functions (PUFs), which can be used for authentication and key storage. Existing PUFs are static, as their PUF responses remain the same regardless when the PUF is queried. Meanwhile, this paper presents the new concept of

Model-Inversion-Resistant Physical Unclonable Neural Network Using Vertical NAND Flash Memory. [PDF]

Adv Sci (Weinh)
Schematic and key features of the proposed forward‐forward physical unclonable neural network (FF‐PUNN), incorporating a concealable physical unclonable function (PUF) layer and forward‐forward (FF) learning. ABSTRACT The growing use of neural networks in privacy‐sensitive applications necessitates architectures that inherently protect both data and ...

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

Photonic Physical Unclonable Function Based on Symmetric Microring Resonator Arrays

, 2023
International audienceWe propose a novel architecture for a photonic Physical Unclonable Function (PUF) based on microring arrays. We demonstrate its uniqueness, verify its random behavior on standard benchmarks, and investigate the impact of the ...

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.

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.

Racemized photonic crystals for physical unclonable function

, 2022
Spontaneous mirror symmetry broken patterns based on the self-assembly of achiral molecules are developed for physical unclonable anticounterfeiting labels. Our chiral PUF shows remarkable performance, which enables next-generation security labels.
