Methoden zur Verbesserung von CMOS integrierten Arbiter-PUFs
Beitrag zu einer Konferenz(Universität Ulm, 2019-08-16)In diesem Beitrag wird eine Auswahl von Methoden zur Verbesserung integrierter CMOS PUFs vorgestellt. Am Beispiel der Arbiter-PUF zeigen wir, dass sowohl die PUF-definierenden Zufallsquellen erheblich optimiert werden ... -
Exploiting Weak PUFs from Data Converter Non-Linearity - E.g. A multibit CT ∆Σ Modulator
Wissenschaftlicher Artikel(Universität Ulm, 2019-08-14)This paper presents a novel approach of deriving Physical Unclonable Functions (PUF) from correction circuits measuring and digitizing non-linearities of data converters. The often digitally available correction data can ... -
An Arbiter PUF employing eye-opening oscillation for improved noise suppression
Beitrag zu einer Konferenz(Universität Ulm, 2018-05-04)Like every integrated circuit, Arbiter-PUFs suffer from any ambience variations such as electrical noise, supply voltage variations and temperature fluctuations. In this work, we show that most bit-errors are related to ... -
Enhanced Arbiter PUFs using custom sized structures for reduced noise sensitivity
Beitrag zu einer Konferenz(Universität Ulm, 2019-08-14)This paper presents a simple yet effective way of improving delay based Physical Unclonable Functions by changing transistor gate sizes only. All utilized components of an Arbiter PUF were simulated in a 90nm CMOS process ... -
In-depth Analysis and Enhancements of RO-PUFs with a Partial Reconfiguration Framework on Xilinx Zynq-7000 SoC FPGAs
Beitrag zu einer Konferenz(Universität Ulm, 2019-08-14)Physical unclonable functions (PUFs) are excellent candidates to generate secret information on-chip without the need for secure storage. Ring-oscillator (RO) based PUFs have been receiving great attention over the years ... -
How to (not) measure self-favoring response bias : an examination of impression management and overclaiming
Dissertation(Universität Ulm, 2019-08-09)The validity of self-report measures is threatened by individuals not responding honestly to questionnaire items. One variant of misrepresentation is the tendency to present oneself overly favorably by providing socially ... -
End-to-End time-continuous emotion recognition for spontaneous interactions
Abschlussarbeit (Master; Diplom)(Universität Ulm, 2019-08-07)Speech emotion recognition has emerged in the area of speech signal research since it can have a signficant role in Artificial intelligent. In the area of speech emotion recognition, hand-engineered features are traditionally ... -
A wideband dielectric waveguide-based 160-GHz radar target generator
Wissenschaftlicher Artikel(Universität Ulm, 2019-06-22)The increasing number of radar sensors in commercial and industrial products leads to a growing demand for system functionality tests. Conventional test procedures require expensive anechoic chambers to provide a defined ... -
Leakage phase noise mitigation for monostatic FMCW radar sensors using carrier transmission
Beitrag zu einer Konferenz(Universität Ulm, 2019-08-06)One common problem of frequency modulated continuous wave radar is leakage from the transmitter to the receiver. The leakage power is orders of magnitude larger than the target return power and appears as a very strong ... -
Verfahren zur adaptiven Bitrateneinstellung des CAN Bus mit Langzeitmonitoring bei hybriden Topologien
Abschlussarbeit (Bachelor)(Universität Ulm, 2019-08-06)Content of this thesis is the development of an adaptive robust process to automatically reach the maximum data rate on the CAN bus in home automation. This is supported by an automatic adjustment of the impedance to ...
