Best Poster Award at SOSP 2026

CS- OS — Wed, 07 Oct 2026 11:14:04 +0000

We are thrilled to announce that Manuel Vögele and colleagues have been awarded the Best Poster Award at the 30th ACM Symposiumon Operating Systems Principles (SOSP ’26).

The award-winning poster, titled „Instant Replay: Process snapshots without waiting for fork“ presents a novel user-space snapshotting mechanism designed to eliminate the steep performance penalties traditionally caused by the fork system call.

While modern applications (like fuzzers, database engines, and video games) rely heavily on fork to create process snapshots, the system call introduces significant execution overhead and costly page faults. To tackle this, Rewind utilizes a lightweight, Just-In-Time (JIT) compilation-based emulator that executes directly within the process’s existing address space. By isolating memory modifications inside a custom memory overlay and only sandboxing instructions that alter the process state, Rewind achieves near-native execution speeds and allows applications to reset to a previous state almost instantaneously.

SOSP is widely recognized as the premier world forum for systems software research, making this recognition a huge success for our group and the faculty at RUB.Congratulations to Manuel and the entire team for their exceptional hard work and dedication!

The Rewind research is part of the DFG project ‚Dynamic Operating-System Specialisation‘ (DOSS), on which we collaborate with researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU). You can find more information about the project, explore the JIT compilation architecture, and view the full poster abstract on our Publications Page and DOSS project page. Please get in touch if you are interested in our research.

The work was partially funded from the Bundesministerium für Forschung, Technologie und Raumfahrt (BMFTR, Federal Ministry of Research, Technology and Space) in Germany for the project SUSTAINET-inNOvAte 16KIS2262 and by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – 539710462; 502228341.

From Awareness into Action

From Awareness into Action

Anja Brüll

24. September 2026

We cordially invite you to our workshop “From Awareness into Action: A Practical Guide to Diversity” on October 8, 2026, co-organized with the Equal Opportunities team of the faculty.

The term diversity gets thrown around a lot, especially in academic environments. It’s a concept that’s not always easy to grasp. It influences how we solve problems, make decisions, collaborate, and shape our working and learning environments every day – whether we notice it or not. Invisible norms, unconscious bias, and power structures shape our interactions and influence who participates, who feels they belong, and whose perspectives are heard. Making diversity and anti-discrimination common goals is a deeply democratic process.

This workshop invites participants to explore these complex dynamics through contextual input, critical reflection, and practical examples, while creating space to discuss questions, experiences, and challenges from their own university contexts. It is aimed at both those who experience(d) discrimination and need empowerment and those who want to learn more to take on responsibility. Together, we will deepen our understanding of diversity and discrimination and translate reflection into meaningful action that strengthens participation, belonging, and equity across teaching, research, administration, and academic collaboration.

Our speakers:

Alejandra Nieves Camacho is anti-discrimination and diversity officer at Berlin University of Arts. Her academic background is in International Relations, with her work focusing on gender, migration and anti-racism.

Dr. Carolin Loysa serves as Equal Opportunities Officer at the Institute for Latin American Studies and as Diversity Officer at Freie Universität Berlin. She is also a research associate, anthropologist, and gender studies scholar in the field of Latin American Studies, focusing on decolonisation, migration, and queer-feminist approaches.

All genders and status groups are welcome. Light refreshments will be provided. The workshop will be held in English.

Please register here until October 2, 2026: https://eveeno.com/142959163.

Looking forward to seeing you there!

Paper presented at ECCV Workshop!

Simon Heilig — Tue, 15 Sep 2026 09:40:00 +0000

Paper presented at ECCV Workshop 2026!

On September 8, our former Master student Roman Demchenko presented our paper „Training-Free Reconstruction-Based AI-Generated Image Detectors Are Inherently Vulnerable to Adversarial Examples“ at the Workshop on AI for Multimedia Forensics & Disinformation Detection (AI4MFDD), which was co-located with the European Conference on Computer Vision (ECCV) in Malmö, Sweden.

In this work, which was co-authored by Jonas Ricker and Asja Fischer, we analyze the adversarial robustness of reconstruction-based AI-generated image detectors. Since these methods do not require any training, it seems reasonable to assume that they are immune to specifically crafted, harmful samples, so-called adversarial examples. However, we demonstrate that this is unfortunately not the case. We develop two novel attack methods that are highly effective and transferable across several detectors in a black-box setting.

Side-Channel Secure CSIDH with Projective Coordinates

Das Paper „Side-Channel Secure CSIDH with Projective Coordinates“ von Jonas Meers, Anna Guinet, Georg Land, Elisabeth Krahmer und Tim Güneysu wurde für die CIC akzeptiert.

Abstract

CSIDH is an isogeny-based Non-Interactive Key Exchange (NIKE) proposed at ASIACRYPT'18. In this work, we present the first masked version of CSIDH and, in fact, any isogeny-based scheme. We develop gadgets to efficiently mask all arithmetics in the underlying finite field and prove them secure in the -probing model. In particular, we develop new gadgets for the Montgomery ladder using the fact that projective values already represent a multiplicative sharing in two variables. The technique (dubbed quotient masking) might be of independent interest. Lastly, we provide an efficient implementation based on High-Security CSIDH (Communications in Cryptology 2024). We show that the relative computational overhead of masking the latter—compared to other state-of-the-art CSIDH implementations—is similar to other masked implementations of post-quantum cryptography primitives.

Our research on AI watermarking was featured in Tagesschau

Simon Heilig — Mon, 17 Aug 2026 15:01:29 +0000

Our research on AI watermarking was featured in Tagesschau!

Our PhD student Andreas Müller was featured in a Tagesschau Online article on the new transparency requirements under Article 50 of the EU AI Act (Regulation (EU) 2024/1689).

The provisions require providers of generative AI systems to make synthetic outputs machine-readable and detectable as AI-generated or manipulated; they also set disclosure duties for deepfakes and certain AI-generated public-interest texts. Access the article here: https://www.tagesschau.de
An accompanying audio version of the report is also available.

The coverage highlights the growing practical relevance of research on robust watermarking and the detection of AI-generated media. As regulatory requirements move from policy into implementation, reliable methods for identifying synthetic content become an important component of transparency, accountability, and public trust.

Standing together in solidarity

31. Juli 2026

Last Saturday’s attack on demonstrators at Christopher Street Day in Berlin has left us shocked and saddened. Especially now, no one should have to feel alone, and we want to support one another and, above all, keep being present.

The Diversity Team offered a space for all faculty members to connect, share thoughts and feelings, or simply to not be alone.

Our thoughts are with those directly affected, the injured, the killed person, their families, and the many who have been traumatized.

We stand together and will not be intimidated.
