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 ...

Self-Timed Physically Unclonable Functions
2012 5th International Conference on New Technologies, Mobility and Security (NTMS), 2012Physically 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
2017Reconfigurable 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

Quantum readout of Physical Unclonable Functions
International Journal of Quantum Information, 2010Physical 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 ...

Formal Analysis of Physically Unclonable Functions
2021 IFIP/IEEE 29th International Conference on Very Large Scale Integration (VLSI-SoC), 2021In this research work, we aim to formalize the analysis of Physically Unclonable Functions (PUF) constructions. First, we present a testability analysis scheme that leverages the correlation spectra properties of Boolean functions to assess the quality of a collection of PUF instances of the same make by comparing its correlation spectra with that of a

The Impact of Aging on a Physical Unclonable Function
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2014On-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

On the learnability of physically unclonable functions
2017Die 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

Clockless Physical Unclonable Functions
2012Physically 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.

MEMS Gyroscopes as Physical Unclonable Functions
Proceedings of the 2016 ACM SIGSAC Conference on Computer and Communications Security, 2016A key requirement for most security solutions is to provide secure cryptographic key storage in a way that will easily scale in the age of the Internet of Things. In this paper, we focus on providing such a solution based on Physical Unclonable Functions (PUFs).
