Overview of the Encrypted Computing Programme
On September 30, 2025, the Agentur für Innovation in der Cybersicherheit (Cyberagentur) unveiled its "Encrypted Computing" (EC2) research programme at a specialist event in Halle (Saale). This initiative aims to enhance data security by ensuring that information remains encrypted even during processing. The event attracted around 40 participants, including project partners, academics, end users, and students from Martin Luther University Halle-Wittenberg, who engaged with the latest research approaches and applications in this field.
Key Technologies and Methods
The EC2 programme focuses on advanced methodologies such as fully homomorphic encryption (FHE) and secure multi-party computation (MPC). These techniques allow for the evaluation of encrypted data without compromising its confidentiality. Additionally, concepts like Private Set Intersection (PSI) and Private Information Retrieval (PIR) were discussed, which facilitate the confidential comparison and retrieval of data.
Insights from Experts
Prof. Dr. Jürgen Freudenberger, head of the Cyberagentur's Key Technology Department, opened the event by outlining the programme's strategic objectives. Keynote speaker Prof. Dr. Zoltán Mann, a Professor of Cybersecurity, highlighted the importance of encrypted data processing as a critical technology for maintaining trust in a digital landscape increasingly vulnerable to threats from quantum computing.
During the event, various project teams presented their ongoing research. Notably, Prof. Dr. Antonia Wachter-Zeh from the Technical University of Munich and Dr. Hannes Bartz from the German Aerospace Centre discussed the PQPrime project, which aims to optimize homomorphic encryption methods for practical applications and develop new cryptographic techniques.
Dr. Sebastian Gajek, founder and managing director of enclaive GmbH, along with Prof. Dr. Peter Scholl from Aarhus University, presented the MPCC project. They explained how secure multi-party computation, utilizing trusted execution environments and secret sharing methods, allows for the analysis of sensitive data without revealing it.
Broader Implications
The two-day event underscored that the EC2 research programme extends beyond fundamental research. It explored potential applications of encrypted data processing in sectors such as healthcare, administration, and defense, emphasizing its role in enhancing the digital sovereignty of Germany and Europe.
Official Statements
The Cyberagentur operates under the Federal Republic of Germany's National Security Strategy, with Prof. Dr. Christian Hummert serving as Scientific Director and Bettina Bubnys as Commercial Director. Dr. Matthias Minihold, Research Officer for Cryptology, is available for scientific inquiries regarding the programme.
