Welcome to KASTEL

The Competence Center for Applied Security Technology (KASTEL) is a competence center for cyber security initiated by the German Federal Ministry of Education and Research (BMBF).

Following the motto "Comprehensible security in the networked world“, KASTEL addresses the challenges posed by the increasing interconnection of previously isolated systems. Of particular importance are the consequences of digitalization in the area of critical infrastructures, for example in the energy industry, in networked mobility or in industrial production.

KASTEL bundles the competencies in the field of IT security at the research location Karlsruhe. The goal is to develop a comprehensive approach instead of isolated partial solutions. The focus will be on comprehensive security in specific application areas, such as power grids, smart mobility, or intelligent factories.

To ensure this security, new threats must be modeled, security objectives described and new methods developed. This can only be achieved through collaboration between cryptographers, IT security specialists, software engineers, network experts, jurists, economists and social scientists - as is the case here at KASTEL.

KASTEL started in 2011 with a term of four years. After a successful evaluation in 2014, the term was extended by the BMBF, and after another successful scientific evaluation and a strategic assessment by the Helmholtz Association, it was finally decided to permanently fund KASTEL.

Paper accepted at the 30th USENIX Security Symposium

The paper “'Now I'm a bit angry:' Individuals' Awareness, Perception, and Responses to Data Breaches that Affected Them” by KASTEL-Scientist Peter Mayer in Cooperation with Yixin Zou, Florian Schaub, and Adam J. Aviv has been accepted for publication at the 30th USENIX Security Symposium, which will be held August 11th to 13th as a virtual event. The paper describes a user study in which participants were confronted with data breaches, that according to exposed their email addresses and other personal information, in order to collect the participants' awareness, perception, and reactions regarding these data breaches.

In Computerwoche Jörn Müller-Quade talks about trustworthy artificial intelligence

According to a recent survey by Bitkom, a large majority of Germans want AI to be safe and demand that AI systems be particularly thoroughly tested before they are used. Certification of AI strengthens trust in the technology. In this context, it is important to strike the right balance in order to maintain Germany's innovative strength.

New article on the right to informational self-determination

Several members of KASTEL, Dr. iur. Anne Steinbrück, Dr. rer. pol. Marcus Wiens, Dr. ing. Pascal Birnstill, Florian Kaiser, Dr. Tim Zander, Prof. (apl.) Dr. Oliver Raabe, Prof. Dr. Frank Schultmann and Prof. Dr. Melanie Volkamer, published a joint article in the German legal journal „Recht auf Datenverarbeitung (RDV 2021, S. 7)“ (Right of information processing). The article analyses the legal arguments of an 2019’s order of the Oberlandesgericht Düsseldorf  (OLG Düsseldorf v. 26.08.2019, Az.: VI Kart 1/19 (V)) from an economical point of view. The order deals with the application of antitrust legislation in the context of violation of privacy rights.
