Security and Privacy Group

The research vision of the Security and Privacy Group at COMSYS is the analysis, design, and evaluation of secure and privacy-preserving communication systems.

To realize this vision, we most notably craft novel security and privacy architectures, paradigms, and mechanisms as well as improve upon existing approaches to security and privacy. We consider all types of systems and networks, e.g. ranging from highly resource-constrained IoT networks to distributed (peer-to-peer) applications and networks and large-scale Cloud deployments.

Our used and developed technologies range from soft privacy solutions such as semantic annotations and behavioral nudges to applied cryptography for strong and provable security and privacy guarantees.

The close cooperation with the other research groups at COMSYS allows us to work closely with domain experts from various types of communication systems.

Currently, we pursue this research vision by tackling the following research topics:

  1. Network Security for the IP-based Internet of Things
    • Secure end-to-end communication of highly resource-constrained devices
    • Delegation of security tasks to less resource-constrained gateways
  2. Security and Privacy in Cloud-based Systems
    • Alternatives to traditional cloud computing
    • Awareness of the usage of cloud services
    • Cloud operations that respect data handling requirements
    • Scalable and secure infrastructures for cloud operations
    • Secure and privacy-preserving outsourcing of sensitive data to the cloud
  3. Privacy Enhancing Techniques (PETs)
    • Quantitative modelling of privacy protection and risk (e.g., Differential Privacy)
    • Secure Two-Party and Multi-Party Computation in mobile scenarios (e.g., Privacy-preserving Indoor Localization)
    • Privacy in distributed scenarios (e.g., Participatory Sensing)
    • Reconciling PETs and user perception of privacy (e.g., empirical user studies)
