To achieve this goal, not only do the cryptographic primitives and protocols need to be secure in theory, they also need to be securely implemented by cryptographic library developers in practice. However, implementing cryptographic algorithms securely is challenging, even for skilled professionals, which can lead to vulnerable implementations, especially to side-channel attacks. For timing attacks, a severe class of side-channel attacks, there exist a multitude of tools that are supposed to help cryptographic library developers assess whether their code is vulnerable to timing attacks. Previous work has established that despite an interest in writing constant-time code, cryptographic library developers do not routinely use these tools due to their general lack of usability. However, the precise factors affecting the usability of these tools remain unexplored. While many of the tools are developed in an academic context, we believe that it is worth exploring the factors that contribute to or hinder their effective use by cryptographic library developers [61]. To assess what contributes to and detracts from usability of tools that verify constant-timeness (CT), we conducted a two-part usability study with 24 (post) graduate student participants on 6 tools across diverse tasks that approximate real-world use cases for cryptographic library developers. We find that all studied tools are affected by similar usability issues to varying degrees, with no tool excelling in usability, and usability issues preventing their effective use. Based on our results, we recommend that effective tools for verifying CT need usable documentation, simple installation, easy to adapt examples, clear output corresponding to CT violations, and minimal noninvasive code markup. We contribute first steps to achieving these with limited academic resources, with our documentation, examples, and installation scripts(1).","lang":"eng"}],"place":"Berkeley","date_created":"2026-04-30T09:31:29Z","type":"journal_article","author":[{"first_name":"M","last_name":"Fourn ","full_name":"Fourn , M"},{"full_name":"Braga, DD","last_name":"Braga","first_name":"DD"},{"first_name":"J","last_name":"Jancar","full_name":"Jancar, J"},{"full_name":"Sabt, M","last_name":"Sabt","first_name":"M"},{"full_name":"Schwabe, P","first_name":"P","last_name":"Schwabe"},{"full_name":"Barthe, G","first_name":"G","last_name":"Barthe"},{"full_name":"Fouque, PA","first_name":"PA","last_name":"Fouque"},{"full_name":"Acar, Y","last_name":"Acar","first_name":"Y"}],"publication_identifier":{"issn":["978-1-939133-44-1"]},"year":"2024","title":"\"These results must be false\": A usability evaluation of constant-time analysis tools","status":"public","date_updated":"2026-04-30T09:32:34Z","publication_status":"published","publisher":"Usenix Assoc","_id":"65534","language":[{"iso":"eng"}],"user_id":"125442"},{"publication_status":"published","date_updated":"2026-04-30T09:32:32Z","status":"public","year":"2024","title":"Chain of Trust: Unraveling References Among Common Criteria Certified Products","publication_identifier":{"isbn":["9783031651748","9783031651755"],"issn":["1868-4238","1868-422X"]},"author":[{"last_name":"Janovsky","first_name":"Adam","full_name":"Janovsky, Adam"},{"full_name":"Chmielewski, Łukasz","last_name":"Chmielewski","first_name":"Łukasz"},{"first_name":"Petr","last_name":"Svenda","full_name":"Svenda, Petr"},{"full_name":"Jancar, Jan","last_name":"Jancar","first_name":"Jan"},{"first_name":"Vashek","last_name":"Matyas","full_name":"Matyas, Vashek"}],"user_id":"125442","doi":"10.1007/978-3-031-65175-5_14","language":[{"iso":"eng"}],"_id":"65536","publisher":"Springer Nature Switzerland","publication":"IFIP Advances in Information and Communication Technology","citation":{"mla":"Janovsky, Adam, et al. “Chain of Trust: Unraveling References Among Common Criteria Certified Products.” <i>IFIP Advances in Information and Communication Technology</i>, Springer Nature Switzerland, 2024, doi:<a href=\"https://doi.org/10.1007/978-3-031-65175-5_14\">10.1007/978-3-031-65175-5_14</a>.","ama":"Janovsky A, Chmielewski Ł, Svenda P, Jancar J, Matyas V.

These so-called fake production costs only occurred when not given the time to mentally prepare the deceptive movement. In the current study, we investigated if extensive practice could reduce the cognitive costs of producing a pass with head fake. Twenty-four basketball novices participated in an experiment on five consecutive days. A visual cue prompted participants to play a pass with or without a head fake either to the left or right side. The cued action had to be executed after an interstimulus interval (ISI) of either 0 ms, 400 ms, 800 ms or 1200 ms, allowing for different movement preparation times. Results indicated higher response initiation times (ITs) and error rates (ERs) for passes with head fakes for the short preparation intervals (ISI 0 ms and 400 ms) on the first day but no difference for the longer preparation intervals (ISI 800 ms and 1200 ms). After only one day of practice, participants showed reduced fake production costs (for ISI 0 ms) and were even able to eliminate these cognitive costs when given time to mentally prepare the movement (for ISI 400 ms). Accordingly, physical practice can reduce the cognitive costs associated with head-fake generation. This finding is discussed against the background of the strengthening of stimulus response associations.</jats:p>"}],"publication":"Psychological Research","keyword":["Arts and Humanities (miscellaneous)","Developmental and Educational Psychology","Experimental and Cognitive Psychology","General Medicine"],"type":"journal_article","department":[{"_id":"17"},{"_id":"266"}],"file":[{"creator":"nboeer","date_created":"2025-11-06T13:32:52Z","date_updated":"2025-11-06T13:32:52Z","relation":"main_file","access_level":"closed","file_size":898697,"file_name":"Böer, Weigelt, Schütz, & Güldenpenning_2024_Practice reduces the costs of producing head fakes in basketball.pdf","success":1,"content_type":"application/pdf","file_id":"62114"}],"date_created":"2023-10-26T09:57:43Z"},{"year":"2024","title":"Security Belts: A Maturity Model for DevOps Teams to Increase the Software Security of their Product - An Experience Report","author":[{"first_name":"Samira","last_name":"Taaibi","full_name":"Taaibi, Samira","id":"55800"},{"last_name":"Dziwok","orcid":"http://orcid.org/0000-0002-8679-6673","first_name":"Stefan","full_name":"Dziwok, Stefan","id":"3901"},{"last_name":"Hermerschmidt","first_name":"Lars","full_name":"Hermerschmidt, Lars"},{"id":"13616","last_name":"Koch","first_name":"Thorsten","full_name":"Koch, Thorsten"},{"id":"11394","first_name":"Sven","last_name":"Merschjohann","full_name":"Merschjohann, Sven"},{"first_name":"Mark","last_name":"Vollmary","full_name":"Vollmary, Mark"}],"publication_status":"accepted","date_updated":"2026-05-08T03:26:03Z","language":[{"iso":"eng"}],"publication":"AMCIS 2024 Proceedings. 13.","abstract":[{"lang":"eng","text":"Persistent security challenges plague DevOps teams due to a deficiency in expertise regarding security tools and methods, as evidenced by frequent security incidents.

Reducing the weight of vehicles can significantly lower the energy or fuel consumed and thus the emissions during operation. One possibility to assess this is the use of a property adapted multi-material systems containing high strength steel, light metals like aluminium or magnesium and fibre reinforced plastics. While expanding the number of materials used new challenges arise for the production and furthermore the joining technology to manufacture the vehicle made of the multi-material systems. One approach to overcome these challenges is to use innovative and adaptable joining techniques which allows the manufacturing of joints of different material combinations. Extensive research activities on the two stage thermo-mechanical joining process with adaptable joining elements was able to demonstrate the great potentials in terms of joining dissimilar materials with good strength. The previously kinematic and path-based fabrication of auxiliary joining elements is modified in this publication to a form-based approach with a perspective of establishing an efficient process chain using easily and cheaply available rods. Based on the new approach to produce the auxiliary joining elements, it can be demonstrated that a reproducible production of the geometry is possible for the investigated steel as well as aluminium material. </jats:p>"}],"_id":"54650","publisher":"Materials Research Forum LLC","language":[{"iso":"eng"}],"user_id":"7850","doi":"10.21741/9781644903131-180","publication_identifier":{"issn":["2474-395X"]},"author":[{"id":"83141","full_name":"Borgert, Thomas","last_name":"Borgert","first_name":"Thomas"},{"first_name":"Ansgar Bernhard","last_name":"Nordieker","full_name":"Nordieker, Ansgar Bernhard","id":"88725"},{"first_name":"Werner","last_name":"Homberg","full_name":"Homberg, Werner","id":"233"}],"conference":{"location":"Toulouse","name":"ESAFORM 2024"},"year":"2024","status":"public","title":"Form-based manufacturing of aluminium and steel auxiliary joining elements as the basis for an efficient joining operation","publication_status":"published","date_updated":"2026-05-12T11:56:47Z"},{"user_id":"7850","volume":9,"publisher":"Elsevier BV","_id":"54649","status":"public","project":[{"name":"TRR 285 - Project Area C","_id":"133"},{"_id":"147","name":"TRR 285 - Subproject C03"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"citation":{"short":"T.

Dieser Beitrag beschreibt die Untersuchungen, inwiefern beim Clinchen zweier Bleche aus der ausscheidungshärtbaren Aluminiumlegierung EN AW-6014 bereits auf Basis der Prozessüberwachung des Kraft-Weg-Verlaufs bzw. des sich daraus ergebenden Energieeintrags auf die mechanischen und elektrischen Eigenschaften der Fügeverbindung geschlossen werden kann. An einer ausgewählten Fügeaufgabe werden im Stufenversuch die gegenseitigen Abhängigkeiten der einzelnen Einflussgrößen sowie des Wärmebehandlungszustands aufgezeigt. Dabei wird zwischen den Bindemechanismen Formschluss und Kraftschluss unterschieden. Die Formschlusskomponente wird anhand der geometrischen Kenngrößen wie Bodendicke, Halsdicke und Hinterschnitt in Mikroskopieuntersuchungen an Schliffbildern und den mechanischen Eigenschaften der Fügeverbindung untersucht, die im Scherzug- und Kopfzugversuch bestimmt werden. Dazu erfolgt zudem die Charakterisierung der Versagensbilder. Zur Quantifizierung der Kraftschlusskomponente der Fügeverbindung werden das Losbrechmoment im Torsionsversuch und der elektrische Widerstand mittels Vier-Leiter-Methode ermittelt und korreliert.","lang":"ger"}],"extern":"1","publication":"Tagung Werkstoffprüfung 2024: Werkstoffe und Bauteile auf dem Prüfstand, Prüftechnik – Kennwertermittlung – Schadensvermeidung"},{"publisher":"Tsinghua University Press","_id":"57742","language":[{"iso":"eng"}],"doi":"10.26599/frict.2025.9441052","user_id":"7850","publication_identifier":{"issn":["2223-7690","2223-7704"]},"author":[{"id":"45779","last_name":"Böhnke","first_name":"Max","full_name":"Böhnke, Max"},{"id":"34782","full_name":"Bielak, Christian Roman","first_name":"Christian Roman","last_name":"Bielak"},{"id":"38279","first_name":"Robert","last_name":"Beck","orcid":"0000-0001-9056-4528","full_name":"Beck, Robert"},{"id":"7850","last_name":"Bobbert","first_name":"Mathias","full_name":"Bobbert, Mathias"},{"first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","id":"32056"}],"status":"public","year":"2024","title":"Development of a friction model for the numerical simulation of clinching processes","article_type":"original","date_updated":"2026-05-12T14:08:38Z","publication_status":"published","date_created":"2024-12-11T14:45:57Z","department":[{"_id":"157"}],"type":"journal_article","citation":{"chicago":"Böhnke, Max, Christian Roman Bielak, Robert Beck, Mathias Bobbert, and Gerson Meschut. “Development of a Friction Model for the Numerical Simulation of Clinching Processes.” <i>Friction</i>, 2024. <a href=\"https://doi.org/10.26599/frict.2025.9441052\">https://doi.org/10.26599/frict.2025.9441052</a>.","short":"M.

However, inherent to plastic forming is the nucleation and growth of defects, whose detrimental effects on the material behaviour can be described by continuum damage models and eventually lead to material failure. As the damage evolution strongly depends on the stress state, a stress-state-dependent model is utilised to correctly track the accumulation. To formulate and parameterise this model, besides classical experiments, so-called modified punch tests are also integrated herein to enhance the calibration of the failure model by capturing a larger range of stress states and metal-forming-specific loading conditions. Moreover, when highly ductile materials are considered, such as the dual-phase steel HCT590X and the aluminium alloy EN AW-6014 T4 investigated here, strong necking and localisation might occur prior to fracture. This can alter the stress state and affect the actual strain at failure. This influence is captured by coupling plasticity and damage to incorporate the damage-induced softening effect. Its relative importance is shown by conducting inverse parameter identifications to determine damage and failure parameters for both mentioned ductile metals based on up to 12 different experiments.","lang":"eng"}]},{"date_created":"2025-01-16T14:17:38Z","type":"book_editor","citation":{"mla":"Bürgel, Christoph, et al., editors. <i>\tZeitschrift Für Romanische Sprachen Und Ihre Didaktik</i>. 2024.","ama":"Bürgel C, Heiderich J, Koch C, Schlaak C, Visser J, eds. <i>\tZeitschrift Für Romanische Sprachen Und Ihre Didaktik</i>.
