The CASA Summer School is an annual event that offers young researchers interesting lectures by high-ranking speakers and the opportunity for international exchange. We cordially invite PhD students, postdoctoral researchers, master's students, and advanced bachelor's students close to graduation from the field of cyber security to participate. They can qualify in advance through an application process.
Join us for the CASA Summer School 2026 at Ruhr-Universität Bochum (Germany) on Cryptography and Distributed Computing from June 22 to 25, 2026.
We are living in the era of large-scale distributed systems where terms such as blockchains, the internet of things, and wide-scale networks have become ubiquitous. It is therefore critical to understand the behaviour of distributed algorithms and cryptography that do not run on a single centralised node but rather are run by many nodes collaboratively. In this summer school, we explore the basics as well as cutting-edge developments in this space that have contributed to a wide-spread adoption of distributed systems in recent years. The summer school covers topics from Consensus Mechanisms to foundational cryptographic protocols like VSS and DKG, as well as Threshold Cryptography and Secure Multi-Party Computation (MPC).
The summer school is open to:
The Summer School takes place at the Veranstaltungszentrum, located on the campus of the Ruhr-Universität Bochum:

When research meets future, new ideas come to life: The CASA RC Trust Summer School 2025 offered participants a space to exchange ideas on the latest developments and topics in their field - this year with a highly relevant focus: AI and security.
From June 16 to 20, over 60 researchers and students brought along their various research topics and discussed them in different formats such as lectures, tutorials or poster sessions. This year's program was organized under the technical direction of the CASA PIs Prof. Asja Fischer, Prof. Ghassan Karame and Prof. Bilal Zafar.

Hands-on learning is a cornerstone of academic growth, and this was also the focus of this year's Summer School crypt@b-it 2024. From August 26 to 30, early-career researchers gathered at Ruhr University Bochum's "Beckmanns Hof" to explore a range of topics in cryptography.
The event featured speakers Prof. Léo Ducas (Leiden University), Anca Nitulescu (Input Output Global, Paris), and Maximilian Gebhardt (German Federal Office for Information Security, BSI). It was organized by the Gesellschaft für Informatik (GI), Fachgruppe Kryptologie (FG Krypto), CASA, and the b-it (Bonn-Aachen International Center for Information Technology), in collaboration with the International Association for Cryptologic Research (IACR).

Creativity is always part of science, and this year's CASA Summer School on Software Security was no exception. The three-day event took place from August 14-16 at the Beckmanns-Hof of the RUB under the chairmanship of the CASA PIs Prof. Kevin Borgolte, Prof. Marcel Böhme and Prof. Alena Naiakshina.
The program included not only classical talks where international speakers gave exciting insights into their research. A Capture the Flag Contest, a Science Escape Game and a Summer Pitch gave participants the opportunity to engage with the topic in a playful way.
Invited to Bochum were Prof. Eric Bodden (Heinz Nixdorf Institute at the University of Paderborn and Fraunhofer IEM), Prof. Helen Sharp (The Open University), Prof. Fish Wang (Arizona State University), Prof. Andreas Zeller (CISPA Helmholtz Center for Information Security), and Prof. Verena Zimmermann (ETH Zurich). In addition, Dr. Tamara Lopez (The Open University) and Fabian Schiebel (Fraunhofer Institute for Mechatronics Design IEM) gave concurrent tutorials.

The CASA Summer School 2022 was held from June 20-23 at the Beckmannshof conference center at the RUB. Focus of the event was the topic "Blockchain Security". About 40 participants enjoyed exciting lectures, worked together in hands-on sessions, and used the opportunity to network.
Among the speakers at the Summer School were Elli Androulaki (IBM Research), Ghassan Karame (CASA), Lucas Davi (Universität Duisburg-Essen) und Clara Schneidewind (Max-Planck-Institut for Security and Privacy).
