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

The Impact of Aging on a Physical Unclonable Function

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2014
On-chip physical unclonable functions (PUFs) have shown promises to solve several security problems. A PUF's behavior needs to be robust against reversible as well as irreversible temporal variabilities in circuits so that noise in the PUF output is minimized. While the effect of the reversible temporal variabilities on PUFs is well studied, sufficient

Strong Authentication with Physical Unclonable Functions

2007
Physical unclonable functions (PUFs) can be used as a cost-effective means to store cryptographic key material in an unclonable way. They can be employed for strong authentication of objects, e.g., tokens, and of persons possessing such tokens, but also for other purposes.
