Gammelgaard, and Alexander Nørgaard Henriksen have, under the supervision of Diego F. Aranha, investigated how flaws in CPU microarchitecture can be exploited to steal cryptographic keys. Their paper, 𝘒𝘦𝘺 𝘙𝘦𝘤𝘰𝘷𝘦𝘳𝘺 𝘰𝘯 𝘚𝘵𝘢𝘵𝘪𝘤 𝘒𝘺𝘣𝘦𝘳 𝘉𝘢𝘴𝘦𝘥 𝘰𝘯 𝘛𝘳𝘢𝘯𝘴𝘪𝘦𝘯𝘵 𝘌𝘹𝘦𝘤𝘶𝘵𝘪𝘰𝘯 𝘈𝘵𝘵𝘢𝘤𝘬𝘴, demonstrates how the Downfall vulnerability can be combined with a Flush+Reload attack technique to reconstruct private keys in post-quantum cryptography, highlighting the deep connection between cryptographic algorithm security and underlying hardware. Fantastic work by Luccas, Rasmus, and Alexander—congratulations on both the publication and presentation 👏 🔗 Read the paper here ➡️ https://lnkd.in/dT9Uz-_M

𝐅𝐫𝐚 𝐤𝐨𝐦𝐦𝐞𝐧𝐭𝐚𝐫𝐬𝐩𝐨𝐫 𝐭𝐢𝐥 𝐩𝐨𝐝𝐜𝐚𝐬𝐭🎙️ Henrik Føhns foreslog, at der burde skabes et europæisk socialt medie som alternativ til fx Facebook. Vores institutleder, Kaj Grønbæk, er enig i behovet – men han peger også på nogle væsentlige udfordringer: 💡 𝐇𝐯𝐞𝐦 𝐬𝐤𝐚𝐥 𝐥𝐚𝐯𝐞 𝐝𝐞𝐭? Vi har den intellektuelle kapacitet, men ikke nok uddannede til at udføre arbejdet. Meta har omkring 25.000 software engineers og computer scientists, mens vi i hele Danmark kun har 18.000 med disse tekniske baggrunde. ⏳ 𝐇𝐯𝐨𝐫 𝐥𝐚𝐧𝐠 𝐭𝐢𝐝 𝐯𝐢𝐥 𝐝𝐞𝐭 𝐭𝐚𝐠𝐞? Mange undervurderer, hvor krævende det er at udvikle et globalt socialt medie. Facebook består af ca. 100 millioner linjer kode, og en dygtig programmør kan i gennemsnit skrive 25.000 linjer om året. Det kræver altså enten rigtig mange udviklere eller rigtig mange år. 💰 𝐇𝐯𝐞𝐦 𝐬𝐤𝐚𝐥 𝐛𝐞𝐭𝐚𝐥𝐞? Vi har et urealistisk forhold til softwarepriser. Musik og streaming betaler vi gerne for, men vi forventer, at browsere, søgemaskiner og sociale medier er gratis – med vores data som betalingsmiddel. Men er vi villige til at betale direkte for et socialt medie for at undgå målrettet markedsføring? 📢 Lyt med i det nyeste afsnit af Techtopia for at høre Kaj Grønbæks vurdering af, hvad der skal til for at skabe et europæisk socialt medie – og hvorfor det ikke er så let, som det lyder. 🎧 Lyt med her ➡️ https://lnkd.in/ddbjJbug

𝐖𝐞𝐥𝐜𝐨𝐦𝐞 𝐭𝐨 𝐨𝐮𝐫 𝐧𝐞𝐰 𝐚𝐬𝐬𝐢𝐬𝐭𝐚𝐧𝐭 𝐩𝐫𝐨𝐟𝐞𝐬𝐬𝐨𝐫 𝐃𝐚𝐧𝐢𝐞𝐥 𝐆𝐫𝐚𝐭𝐳𝐞𝐫 👋🏻😀 We are thrilled that Daniel has chosen to stay at Aarhus University as a Tenure-Track Assistant Professor in the Logic and Semantics group! Daniel first joined us as a PhD student under Lars Birkedal, followed by a postdoc and a visiting research position at University of Oxford. His research focuses on type theory and category theory, with a particular interest in higher category theory and dependent type theory. By applying mathematical techniques to programming languages, his work aims to develop more expressive and reliable tools for both mathematicians and software engineers. Daniel brings deep expertise in modal and homotopy type theory, and we are excited to see his contributions continue to shape the field! 🔗 Read more about Daniel’s research and key publications: https://lnkd.in/dii66iRr #ComputerScience #NewFaculty #ProgrammingLanguages #TypeTheory 📸: Krog Studios

F.eks. er EU-ansøgere til Datalogi steget fra 109 i 2021 til 190 i 2025, mens non-EU-ansøgere er mere end tredoblet fra 90 til 268. 👩💻 𝐅𝐥𝐞𝐫𝐞 𝐤𝐯𝐢𝐧𝐝𝐞𝐫 𝐯æ𝐥𝐠𝐞𝐫 𝐈𝐓: Den positive udvikling gælder også kønsbalancen. Antallet af kvindelige ansøgere på Datalogi er næsten tredoblet siden 2021, og kvinder udgør næsten 28% af alle ansøgning – særligt drevet af internationale kvindelige ansøgere. Et internationalt og diversificeret studiemiljø styrker vores uddannelser, faglige miljø og forskning. Vi ser frem til at byde en masse nye talentfulde studerende velkommen!

𝐖𝐡𝐞𝐧 𝐭𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲 𝐚𝐧𝐝 𝐜𝐨𝐥𝐥𝐚𝐛𝐨𝐫𝐚𝐭𝐢𝐨𝐧 𝐦𝐚𝐤𝐞 𝐚 𝐫𝐞𝐚𝐥 𝐝𝐢𝐟𝐟𝐞𝐫𝐞𝐧𝐜𝐞 ⌨️🤝 After multiple shoulder surgeries, programming became nearly impossible for computer science student Stine Havgaard. Faced with the difficult choice of taking a leave of absence or dropping out, she found support from her lecturer Clemens Nylandsted Klokmose, who shared her challenge with colleagues and students. This led to IT Product Development student Joakim Rosenfeldt Pedersen stepping up to build a custom one-handed keyboard for Stine - enabling her to continue her studies. This story is a great example of what makes our department special: a strong, supportive community where students, researchers, and educators work together to solve real-world challenges 👏 🔗 Read the full story here: https://lnkd.in/d_zSFWYR A huge thank you to Clemens, Joakim, and everyone who contributed ideas!

His work extends classical models to better understand node selection in evolving systems and uncertain environments. Additionally, he developed methods for detecting persistently connected subgraphs in temporal networks and aligning smaller structures within larger networks. These insights contribute to a more advanced understanding of diffusion dynamics and structural detection in large-scale graphs. Good luck, Petros!

Spatial computing smelter den digitale og fysiske verden sammen 🤖🌍 Teknologien gør det muligt at se og interagere med data i den virkelige verden – fra arkitekter, der visualiserer bygninger på byggepladsen, til kirurger, der ser 3D-modeller af tumorer direkte på patienten. I en artikel fra TV2 fremhæver professor Niklas Elmqvist spatial computing og AI har potentialet til at revolutionere alt fra sundhedsvæsenet til byplanlægning eller underholdning. 🔗 Læs mere her https://lnkd.in/eHe_dvvx
