The current research topics of our group can be characterized by the following keywords:

1. Protection of Communication Infrastructures,
2. Security Aware Engineering of Networked Information Systems,
3. Innovative Protocols and Applications of mobile und ubiquitous Systems as well as
4. Peer-to-Peer based Support of Multimedia Streaming Applications

Our objective in these areas is to design new protocol mechanisms, architectures and implementation concepts, to realize them in terms of research prototypes, and to obtain experiences and data concerning performance characteristics in realistic application scenarios.
