New approaches to secure data processing
Cyberagentur presented its "Encrypted Computing" research programme in Halle
On 30 September 2025, Agentur für Innovation in der Cybersicherheit presented the "Encrypted Computing" (EC2) research programme at a specialist event in Halle (Saale). Around 40 participants from project partners, academia, end users and students from Martin Luther University Halle-Wittenberg took the opportunity to gain insights into current research approaches and fields of application.
The EC2 programme aims to keep data encrypted even during processing. Methods such as fully homomorphic encryption (FHE) and secure multi-party computation (MPC) are intended to enable information to be evaluated without compromising its confidentiality. In addition, concepts such as Private Set Intersection (PSI) and Private Information Retrieval (PIR), which were developed for the confidential comparison and retrieval of data, were presented.
The head of the Cyberagentur's Key Technology Department, Prof. Dr. Jürgen Freudenberger, opened the event with an overview of the programme's strategic aims. Keynote speaker Prof. Dr. Zoltán Mann, Professor of Cybersecurity, then emphasised that encrypted data processing is a key technology for ensuring trust in an increasingly digitalised world threatened by quantum computers.
The participating project teams took the opportunity to present their research work. Prof. Dr Antonia Wachter-Zeh, Chair of Codes and Cryptography at the Technical University of Munich, and Dr Hannes Bartz, Head of the Quantum-Resistant Cryptography Group at the German Aerospace Centre, provided insights into the PQPrime project. Here, homomorphic encryption methods are being optimised for practical use and new cryptographic methods are being developed.
The MPCC project was presented by Dr Sebastian Gajek, founder and managing director of enclaive GmbH, and Prof. Dr Peter Scholl, professor of cryptography at Aarhus University. They explained how secure multi-party computation based on trusted execution environments and secret sharing methods creates frameworks that enable analysis of sensitive data without disclosing it.
The second day focused entirely on presentations by stakeholders, who introduced their use cases. Among them were the Federal Office for Information Security (BSI) and the German Armed Forces Centre for Cyber Security (ZCSBw).
The two-day event made it clear that the EC2 research programme goes beyond pure basic research. Perspectives were presented on how encrypted data processing can be applied in areas such as health, administration and defence, and how it contributes to the digital sovereignty of Germany and Europe.

Background: Cyberagentur
The Agentur für Innovation in der Cybersicherheit GmbH (Cyberagentur) was founded in 2020 as a wholly owned subsidiary of the German Federal Government under the joint leadership of the German Federal Ministry of Defence and the German Federal Ministry of the Interior and Community with the aim of taking an application-strategy-oriented and cross-departmental view of internal and external security in the field of cybersecurity. Against this background, the work of the Cyberagentur is primarily aimed at the institutionalised implementation of highly innovative projects that carry a high risk in terms of achieving their objectives, but at the same time have a very high potential for disruption if successful.
The Cyberagentur is part of the Federal Republic of Germany's National Security Strategy.
The Cyberagentur is headed by Prof. Dr Christian Hummert as Scientific Director and Bettina Bubnys as Commercial Director.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
