A theoretical analysis of QR-PUFs — •Giulio Gianfelici, Hermann Kampermann, and Dagmar Bruß — Institut für Theoretische Physik III, Heinrich-Heine-Universität Düsseldorf, D-40225 Düsseldorf, Germany

Physical Unclonable Functions [1] (PUFs) are physical systems with a challenge-response behaviour intended to be hard to clone or simulate. This emerging technology has been proposed in several cryptographic protocols, with particular emphasis on authentication protocols [1]. Later on, extensions of such systems to quantum protocols, the so-called Quantum Readout of PUFS (QR-PUF) [2], were suggested. A major issue of the research on PUFs is the lack of a well-defined agreement about theoretical assumptions and main properties behind the intuitive ideas of QR-PUFs, which limits our ability to characterise the security of cryptographic protocols. We develop a theoretical framework in which we define and quantify the security properties of QR-PUFs. As a first implementation of this framework, we design a program to simulate the behaviour of QR-PUFs in order to study their properties and to test their efficiency under the requirements of secure cryptographic protocols. The program will be also a basis for a comparison between the performances of different QR-PUFs, and between QR-PUFs and classical PUFs.
