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).

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 ...

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.

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

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.

On the physical security of physically unclonable functions

2017
Reconfigurable hardware is the primary component of electronic embedded devices employed in several applications ranging from wireless communication to cloud computing. Due to their significant role these modern platforms are targets of intellectual property (IP) piracy and tampering. Cloning of a design or manipulation of its content is carried out by

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 ...

Clockless Physical Unclonable Functions

2012
Physically Unclonable Functions (PUFs) exploit the physical characteristics of silicon and provide an alternative to storing digital encryption keys in non-volatile memory. A PUF maps a unique set of digital inputs to a corresponding set of digital outputs.

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 ...

On the learnability of physically unclonable functions

2017
Die Verbreitung von Integrated Circuits (ICs) steigt immer weiter. Damit erhöht sich allerdings auch das Risiko, dass Sicherheitslücken in diesen ausgenutzt werden. Angreifer haben bereits demonstriert, dass ein großes Spektrum an Angriffen mittels der genannten Sicherheitslücken möglich ist, um vertrauliche Informationen (z.B. geistiges Eigentum) oder
