Physical Uncloneable Functions (PUF) are systems whose physical behavior to different inputs can be measured reliably, yet cannot be cloned in a physical replica. Existing designs propose to derive uncloneability from an assumed practical impossibility of exactly replicating inherent manufacturing variations, e.g., between individual chipset instances.

Experimental Hardware for Coating PUFs and Optical PUFs
2007In this chapter we discuss the hardware that was used to perform experiments on physical unclonable functions (PUFs).We describe the measurement setups and experimental samples in the case of coating PUFs and optical PUFs. These are two vastly different systems-the former based on integrated circuit (IC) technology and the latter on laser optics.

Key storage is a well-known security issue. Usually, keys are generated and then stored in an non-volatile memory (NVM). A promising alternative are the so-called physical unclonable functions (PUFs). These functions extract key material directly from manufacturing variabilities of a device. One example of such a PUF is the SRAM-PUF.

G-PUF: An Intrinsic PUF Based on GPU Error Signatures
2020 IEEE European Test Symposium (ETS), 2020Physically Unclonable Functions (PUFs) are security primitives that provide trustworthy hardware for key-generation and device authentication. Among them, in contrast to dedicated PUFs, intrinsic PUFs are created from existing hardware components that exploit their variability through software.

2013 Workshop on Fault Diagnosis and Tolerance in Cryptography, 2013
In this work we consider the suitability of Phyiscaly Unclonable Functions (PUFs) for high-security applications. For PUFs to be considered secure in such scenarios they must be resilient to both semi-invasive and fully-invasive attacks. We introduce a new failure analysis technique for semi-invasive, single-trace, backside readout of logic states.

PUF Interfaces and their Security
2014 IEEE Computer Society Annual Symposium on VLSI, 2014In practice, any integrated physical unclonable function (PUF) must be accessed through a logical interface. The interface may add additional functionalities such as access control, implement a (measurement) noise reduction layer, etc. In many PUF applications, the interface in fact hides the PUF itself: users only interact with the PUF's interface ...

On the Amount of Entropy in PUFs
2007The aim of this chapter is to provide an information-theoretic framework for the analysis of physical unclonable function (PUF) security. We set up this framework and then apply it to optical PUFs and coating PUFs. From the description of PUFs in Chapter 1 some obvious questions arise in the context of the security primitives discussed in Part I.

Strong PUFs and their (physical) unpredictability
Proceedings of the Workshop on Embedded Systems Security, 2013Physically Unclonable Functions are more and more important in the design of secure hardware, as they can ensure properties that conventional cryptography can not. In this paper we clarify the relations between strong PUFs and their unpredictability. For this purpose we first introduce an alternative definition for physical unpredictability, where the ...
