TY - CONF AB - The battle of developing hardware Trojans and corresponding countermeasures has taken adversaries towards ingenious ways of compromising hardware designs by circumventing even advanced testing and verification methods. Besides conventional methods of inserting Trojans into a design by a malicious entity, the design flow for field-programmable gate arrays (FPGAs) can also be surreptitiously compromised to assist the attacker to perform a successful malfunctioning or information leakage attack. The advanced stealthy malicious look-up-table (LUT) attack activates a Trojan only when generating the FPGA bitstream and can thus not be detected by register transfer and gate level testing and verification. However, also this attack was recently revealed by a bitstream-level proof-carrying hardware (PCH) approach. In this paper, we present a novel attack that leverages malicious routing of the inserted Trojan circuit to acquire a dormant state even in the generated and transmitted bitstream. The Trojan's payload is connected to primary inputs/outputs of the FPGA via a programmable interconnect point (PIP). The Trojan is detached from inputs/outputs during place-and-route and re-connected only when the FPGA is being programmed, thus activating the Trojan circuit without any need for a trigger logic. Since the Trojan is injected in a post-synthesis step and remains unconnected in the bitstream, the presented attack can currently neither be prevented by conventional testing and verification methods nor by recent bitstream-level verification techniques.

Um zu evaluieren, welche Gestaltungsaspekte ein wirkungsvolles Erklärvideo ausmachen, ist es das Ziel der vorliegenden Masterarbeit herauszufinden, welchen Einfluss die kohärente Gestaltung eines Erklärvideos hat. Dazu wird die Forschungsfrage gestellt: „Welchen Einfluss hat die kohärente Gestaltung eines Erklärvideos auf den dadurch hervorgerufenen Lernzuwachs im Vergleich zu einem in der Hinsicht nicht optimierten Video?“ Um die Forschungsfrage zu beantworten, ist eine quantitative Studie im Prä- und Posttestdesign mit Schüler:innen der Jahrgangsstufe Q1 durchgeführt worden. Außerdem wurde in verschiedenen Kategorien nach einer Bewertung der Videos gefragt. Die Auswertung zeigt, dass durch das optimierte Video mit einem kleinen Effekt bessere Ergebnisse erzielt wurden, diese aber nicht signifikant und auch nicht für alle Aufgaben besser sind. Die Schüler:innen bewerteten das nicht optimierte Video in allen Kategorien besser als das optimierte Video. Auch dieses Ergebnis ist nicht signifikant.

The fsQCA technique assumes that relationships are based on a set–subset relationship. This assumption is fundamental when decision-makers are affected by information asymmetry and are, thus, required to jointly evaluate the credibility and reliability of a range of external signals. This issue also affects consumers in markets for cultural goods, where the quality of products is not known with certainty in advance of the purchase decision. Our study uses fsQCA to establish the effect of different quality signals on consumption in the US market for video game software. Our results show that reviews from professional critics alongside brand extension and multi-platform release strategies act as signals of product quality and, therefore, lead to high sales performance.

What remains unexplored in this context is changes in editorship and/or changes in the composition of the wine tasting teams working for the respective guide. Using data from two particularly prestigious German wine guides (Gault Millau and Vinum), this paper shows that these latter changes have a rather small, yet statistically significant impact on changes in winery ratings. Thus, consumers are well-advised to consider these changes before making their purchasing decision.
