A theoretical framework for 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 (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. Recently, extensions of such systems to quantum protocols, the so called Quantum Readout of PUFS (QR-PUF), were suggested. However, a well-defined agreement about theoretical assumptions and definitions behind the intuitive ideas of QR-PUFs, and therefore our ability of characterising the security of cryptographic protocols, is limited. We aim to build a theoretical framework in which we define and quantify the security properties of QR-PUFs. Such a framework will allow us to develop new protocols to derive security thresholds for QR-PUF authentication.
