Welcome at the Chair of IT Security

We work on all aspects of technical data protection and network and IT security. We are primarily interested in privacy, i.e. the protection of individuals against the misuse of their data.

Over the past decades, digital technologies have developed rapidly. The advent of digital transformation and the interconnectivity of all areas of life opens up a wealth of new possibilities. Autonomous networked vehicles, cloud computing, industry 4.0, virtual reality with haptic feedback, online banking or social networks are just a few keywords that are changing the way and quality of life. However, this development also brings with it a number of challenges that people often do not immediately grasp, but which may well conflict with their interests.

Our research group is engaged in the development and analysis of security concepts that protect from all types of potential attackers on such systems. We are also interested in the development of technologies that promote data protection in order to protect privacy in the digital world. Finally, we develop protocols and algorithms to secure the underlying infrastructures for communication and computation.

We are part of KASTEL - Research for more security.

Paper accepted at 'USENIX Security 2021'

Our paper “Inexpensive Brainwave Authentication: New Techniques and Insights on User Acceptance” has been accepted for presentation at the 30th USENIX Security Symposium. In this research, we explore and evaluate different brain biometric techniques to authenticate users with consumer BCI tools and investigate user perceptions towards accepting such technologies. Our results show that it is feasible to recognize users based on brain responses to images. With regard to adoption, users call for simpler devices, faster authentication, and better privacy.
