Physical unclonable functions

Proceedings of the 3rd international workshop on Trustworthy embedded devices, 2013
The concept of the Physical Unclonable Function (PUF) is exhaustively characerised as an information storage device with a security mechanism that shall impede the duplication of its specified functionality and that is indivisible from its storage mechanism.

Physical unclonable functions

Nature Electronics, 2020
A physical unclonable function (PUF) is a device that exploits inherent randomness introduced during manufacturing to give a physical entity a unique ‘fingerprint’ or trust anchor. These devices are .of potential use in a variety of applications from anti-counterfeiting, identification, authentication and key generation to advanced protocols such as ...

Physically unclonable functions

Proceedings of the 21st edition of the great lakes symposium on Great lakes symposium on VLSI, 2011
CMOS process variations are considered a burden to IC developers since they introduce undesirable random variability between equally designed ICs. However, it was demonstrated that measuring this variability can also be profitable as a physically unclonable method of silicon device identification.

Paintable Physical Unclonable Functions using DNA

Advanced Materials, 2023
AbstractControversy over artwork's authenticity is ongoing despite numerous technologies for copyright protection. Artists should build their own ways to protect the authority, but these are still open to piracy. Here, a platform is proposed for developing anticounterfeiting labels based on physical unclonable functions (PUFs), in an artist‐friendly ...

Capacitive physically unclonable function

2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE), 2017
Digital electronic type of physical unclonable functions (PUFs) are vulnerable to modeling attacks. They also suffer from errors due to temporary environmental variations, such as the variation of the ambient temperature. Motivated by that, we designed a new mixed-signal PUF using 45nm MOSFET technology.

Cloning Physically Unclonable Functions

2013 IEEE International Symposium on Hardware-Oriented Security and Trust (HOST), 2013
As system security demands continue to evolve, Physically Unclonable Functions (PUFs) are a promising solution for secure storage on Integrated Circuits (ICs). SRAM PUFs are among the most popular types of PUFs, since they require no additional circuitry and can be implemented with on-die memories such as caches and data memory that are readily ...

Optical physical unclonable function

2017 IEEE 60th International Midwest Symposium on Circuits and Systems (MWSCAS), 2017
Many military and commercial systems require a unique digital identification for authentication, key derivation, and other purposes. Our approach uses an optical physical unclonable function (PUF) that can be implemented on printed circuit boards (PCB).

Threshold Physical Unclonable Functions

2019 IEEE 49th International Symposium on Multiple-Valued Logic (ISMVL), 2019
Physical Unclonable Functions (PUFs) have been proposed as a tamper-resistant alternative to the traditional methods for secret key generation and challenge-response authentication. Although many different types of PUFs have been presented, the search for more efficient, reliable and secure PUF designs continues. In this paper, we introduce a new class

Quantum readout of Physical Unclonable Functions

International Journal of Quantum Information, 2010
Physical unclonable functions (PUFs) are physical structures that are hard to clone and have a unique challenge-response behavior. The term PUF was coined by Pappu et al. in 2001. That work triggered a lot of interest, and since then a substantial number of papers has been written about the use of a wide variety of physical structures for different ...

Sensor physical unclonable functions

2010 IEEE International Symposium on Hardware-Oriented Security and Trust (HOST), 2010
We propose a novel variety of sensor that extends the functionality of conventional physical unclonable functions to provide authentication, unclonability, and verification of a sensed value. This new class of device addresses the vulnerability in typical sensing systems whereby an attacker can spoof measurements by interfering with the analog signals ...
