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 …

Hardware-based cryptography that exploits physical unclonable functions is required for the
secure identification and authentication of devices in the Internet of Things. However …

Entropy is a measure of uncertainty or randomness. It is the foundation for almost all
cryptographic systems. True random number generators (TRNGs) and physical unclonable …

This chapter introduces the reader to the basic concept of a physically unclonable function
or PUF. Many research results on this topic were published over recent years in a variety of …

We propose a systematic method to evaluate and compare the performance of physical
unclonable functions (PUFs). The need for such a method is justified by the fact that various …

In this paper we demonstrate the first real-world cloning attack on a commercial PUF-based
RFID tag. The examined commercial PUFs can be attacked by measuring only 4 protocol …

We present PUFKY: a practical and modular design for a cryptographic key generator based
on a Physically Unclonable Function (PUF). A fully functional reference implementation is …

In this paper, we analyze ring oscillator (RO) based physical unclonable function (PUF) on
FPGAs. We show that the systematic process variation adversely affects the ability of the RO …

Abstract Physically Unclonable Functions (PUFs) are an emerging technology and have
been proposed as central building blocks in a variety of cryptographic protocols and security …

The quantitative performance indicators of Physical Unclonable Functions (PUFs)-
Randomness, Steadiness, Correctness, Diffuseness and Uniqueness-are strictly defined …
