Welcome at the Chair of Privacy and 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 the KASTEL Security Research Labs, as well as the excellence cluster CeTI, the Centre for Tactile Internet with Human-in-the-Loop.
The paper Pirates: Anonymous Group Calls Over Fully Untrusted Infrastructure
(Christoph Coijanovic, Akim Stark, Daniel Schadt, Thorsten Strufe) has been accepted at ACISP 2024!
In this paper the scientists construct a system which allows anonymous group voice calls – even over infrastructure which might be malicious. Their system is the first one to meet the recommendation of a sub-400 millisecond latency.
Congratulations!

On April 12, 2024, our researcher Patricia Guerra Balboa has participated in the FameLab competition for science communication with her presentation about Differential Privacy and the anonymization of trajectories. She was awarded the silver medal and the audience price, which earns her an invitation to the national finals in Bielefeld. Congratulations!

Patricia’s entry (YouTube)On March 6, Prof. Lam Kwok Yan, Director of the Digital Trust Center in Singapore and Vice President of Nanyang Technological University, visited the KASTEL Security Research Labs in Karlsruhe. After presentations by the SECUSO research group which focuses on the human factor in IT security, the chair of Privacy and Security has shown parts of its ongoing research. Here, we demonstrated the risks attached to smart cities and their diverse and ubiquitous sensors. The data collected by various sensors is shown live on our demonstrator, providing an accessible visualization.
Article on the KASTEL siteOn February 29, Mr. Ioannis Legouras, head of the Brussels Office of the Helmholtz Association, visited KASTEL in Karlsruhe. In addition to a presentation by the Chair of Cryptography and Security about new approaches to securely process sensitive information, he was also given a demonstration of current research at the Chair of Privacy and Security. Here, we demonstrated the risks that arise in Smart Cities, as sensors collect more and a wider variety of data about citizens.
