A formal definition and a new security mechanism of physical unclonable functions
, 2012 The characteristic novelty of what is generally meant by a "physical unclonable function" (PUF) is precisely defined, in order to supply a firm basis for security evaluations and the proposal of new security mechanisms.

, 1987 Physically Unclonable Functions (PUFs) are key tools in the construction of lightweight authentication and key exchange protocols. So far, all existing PUF-based authentication protocols follow the same paradigm: A resource-constrained prover, holding a ...

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.

A new Definition and Classification of Physical Unclonable Functions
, 2015 A new definition of "Physical Unclonable Functions" (PUFs), the first one that fully captures its intuitive idea among experts, is presented. A PUF is an information-storage system with a security mechanism that is 1. meant to impede the duplication of

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.

Multiply Constant-Weight Codes and the Reliability of Loop Physically Unclonable Functions
, 2014 We introduce the class of multiply constant-weight codes to improve the reliability of certain physically unclonable function (PUF) response. We extend classical coding methods to construct multiply constant-weight codes from known $q$-ary and constant ...

CalyPSO: An Enhanced Search Optimization based Framework to Model Delay-based PUFs
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Delay-based Physically Unclonable Functions (PUFs) are a popular choice for “keyless” cryptography in low-power devices. However, they have been subjected to modeling attacks using Machine Learning (ML) approaches, leading to improved PUF designs that ...

Quantum cloning attacks against PUF-based quantum authentication systems
, 2016 With the advent of Physical Unclonable Functions (PUFs), PUF-based quantum authentication systems (QAS) have been proposed for security purposes and recently proof-of-principle experiment has been demonstrated.
