Introduction
My research interests are hardware security, especially Physical Unclonable Functions, new memory technologies like MRAM, FRAM, and ReRAM, as well as different FPGA implementations. I'm also working on Physical Unclonable Functions on single circuit elements like Memristors or Carbon nanotube field-effect transistors. I'm currently working towards my Ph.D. degree in the Computer Science Department of the University of Passau.

In this work, we introduce two new types of Physical Unclonable Functions (PUFs) based on memristor arrays. Both PUFs use the output behavior of memristor cells when an excitation signal is applied to their input. First, the cells are identified by decomposing the signal response into different frequencies using the discrete Fourier transformation...
The ubiquity and pervasiveness of modern Internet of Things (IoT) devices opens up vast possibilities for novel applications, but simultaneously also allows spying on, and collecting data from, unsuspecting users to a previously unseen extent. This paper details a new attack form in this vein, in which the decay properties of widespread, off-the-sh...
In this work, we explored a highly robust and unique Physical Unclonable Function (PUF) based on the stochastic assembly of single-walled Carbon NanoTubes (CNTs) integrated within a wafer-level technology. Our work demonstrated that the proposed CNT-based PUFs are exceptionally robust with an average fractional intra-device Hamming distance well be...
The Automotive Service-Oriented software Architecture (ASOA) is a framework for the effective design, fast deployment, and efficient maintenance of automotive software architectures, facilitating reliable communication among loosely coupled services. It maintains a global view of functional units, allowing them to be updated, replaced, and reconnec...
In this work, we analyse Commercial Off-The-Shelf (COTS) Resistive Random Access Memory (ReRAM) modules for their suitability to implement a novel runtime-accessible True Random Number Generator (TRNG). For this purpose, modules from two different manufacturers (Adesto Technologies and Fujitsu) were tested, which exhibited distinct characteristics...

Physical Unclonable Functions (PUFs) are increasingly used in the process of securing applications. For this purpose, it is crucial that the PUF satisfies all the required properties adequately, including Unpredictability. An important aspect of Unpredictability is Randomness, which includes being free of spatial correlation effects. However, most...
p>This work presents the hardware demonstrator of a secure encryption system based on synchronised Chua chaotic circuits. In particular, the presented encryption system comprises two Chua circuits that are synchronised using a dedicated bidirectional synchronisation line. One of them forms part of the transmitter, while the other of the receiver. B...

p>In this work, we examine the potential of Physical Unclonable Functions (PUFs) that have been implemented on NAND Flash memories using programming disturbances to act as sustainable primitives for the purposes of lightweight cryptography. In particular, we investigate the ability of such PUFs to tolerate temperature and voltage variations, and ex...

In this work, we present a Physical Unclonable Function (PUF) implemented on a Commercial Off-The-Shelf (COTS) NAND Flash memory module using programming disturbances, and examine the robustness of its responses to environmental variations. In particular, we test a removable Flash memory module serving as a PUF, under nominal conditions, as well as...
