Physical Unclonable Functions: A Primer

open access: yesIEEE Security & Privacy, 2014
Physical unclonable functions (PUFs) make use of the measurable intrinsic randomness of physical systems to establish signatures for those systems. PUFs provide a means to generate unique keys that don't need to be stored in nonvolatile memory, and they offer exciting opportunities for new authentication and supply chain security technologies.

Quantifying the Sensitivity and Unclonability of Optical Physical Unclonable Functions

open access: yesAdvanced 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

Modeling attacks on physical unclonable functions [PDF]

open access: yesProceedings 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.
