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

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

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.

MEMS Gyroscopes as Physical Unclonable Functions

Proceedings of the 2016 ACM SIGSAC Conference on Computer and Communications Security, 2016
A 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).

Physical unclonable function with tristate buffers

2008 IEEE International Symposium on Circuits and Systems, 2008
The lack of robust tamper-proofing techniques in security applications has provided attackers the ability to virtually circumvent mathematically strong cryptographic primitives by directly attacking the hardware. Consequently, physical tamper-proofing has emerged as an essential element in secure system design.

On the Encryption of the Challenge in Physically Unclonable Functions

2019 IEEE 25th International Symposium on On-Line Testing and Robust System Design (IOLTS), 2019
Physically Unclonable Functions (PUFs) are cryptographic primitives used to implement low-cost device authentication and secure secret key generation. Weak PUFs (i.e., devices able to generate a single signature or to deal with a limited number of challenges) and Strong PUFs (i.e., devices able to deal with large number of challenges) are widely ...

On testing physically unclonable functions for uniqueness

2016 17th International Symposium on Quality Electronic Design (ISQED), 2016
A number of applications from smartcard to ePassport to eID depend on preventing unauthorized access to hardware and software functionality. Physically Unclonable Functions (PUF) rely on manufacturing process variations to create unique identifiers that can be used for various security applications including authentication and secure access.

Quaternary Debiasing for Physically Unclonable Functions

2018 IEEE 48th International Symposium on Multiple-Valued Logic (ISMVL), 2018
This paper proposes a new multiple-valued debiasing method for extracting uniform random binary responses from physically unclonable functions (PUFs). The proposed method handles PUF responses as quaternary values and extracts the corresponding binary responses in a stable and ef?cient manner.

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.
