Computational optical physical unclonable functions

2017 International Carnahan Conference on Security Technology (ICCST), 2017
Physical unclonable functions (PUFs) are devices which are easily probed but difficult to predict. Optical PUFs have been discussed within the literature, with traditional optical PUFs typically using spatial light modulators, coherent illumination, and scattering volumes; however, these systems can be large, expensive, and difficult to maintain ...

Cyberattack‐Resistant Cholesteric Liquid Crystal‐Based Physical Unclonable Function Keys

Advanced Photonics Research
Physical unclonable functions (PUFs) are the new paradigm for the development of anticounterfeiting devices. Optical PUFs, which use the properties of light and how it interacts with materials to create unique identifiers, are attractive due to their ...

A physical unclonable function based on variations of write times in STT-MRAM due to manufacturing defects [PDF]

AIP Advances
A physical unclonable function (PUF) utilizes the unclonable random variations in a device’s responses to a set of inputs to produce a unique “biometric” for authentication.

On Error Correction for Physical Unclonable Functions

CoRR, 2015
Physical Unclonable Functions evaluate manufacturing variations to generate secure cryptographic keys for embedded systems without secure key storage. It is explained how methods from coding theory are applied in order to ensure reliable key reproduction. We show how better results can be obtained using code classes and decoding principles not used for

Emerging Physical Unclonable Functions With Nanotechnology

IEEE Access, 2016
Physical unclonable functions (PUFs) are increasingly used for authentication and identification applications as well as the cryptographic key generation. An important feature of a PUF is the reliance on minute random variations in the fabricated hardware to derive a trusted random key. Currently, most PUF designs focus on exploiting process variations

Privacy-Preserving Authentication Based on PUF for VANETs

Future Internet
The secret key is stored in an ideal tamper-proof device so that a vehicle can implement a secure authentication with the road-side units (RSUs) and other drivers. However, some adversaries can capture the secret key by physical attacks.

Sensitivity of the Threshold Current for Switching of a Magnetic Tunnel Junction to Fabrication Defects and Its Application in Physical Unclonable Functions

Applied Sciences
A physical unclonable function (PUF) leverages the unclonable random variations in device behavior due to defects incurred during manufacturing to produce a unique “biometric” that can be used for authentication.
