With respect to Car-2-X Communications, our research focuses on the different Communication Principles and protocols that are necessary for information exchange in vehicular networks. Based on such principles, we further study the problems and questions that are related to the Scalability of vehicular networks, and analyse whether communication between vehicles (or from infrastructure to vehicles) can improve safety on the road, reduce travel time or reduce fuel consumptions.

With respect to Networked Content Access our group focuses on two subfields: The World Wide Web and Identity Management. In the research field World Wide Web we explore new possibilities and risks arising from the analysis of networked information in the WWW. We develop and employ Web Crawlers that are data protection compliant to analyze large-scale Web sites and Online Social Networks as Facebook or Xing. Our central research questions are the threat to privacy resulting from linking Online Social Network profiles and the development and evaluation of novel algorithms for extracting the Information Architecture of Web Sites more precisely. In the context of Identity Management, our group explores different approaches to manage and map multiple (digital) identities of one single person onto each other. Such a mapping is required in order to provide authentication and authorization across independent entities or 'realms'. The core aspects of our work in this field are Attribute Management, Access Management and Provisioning of user-related (identity) information. [more]
Our third research field addresses the opportunities and challenges of modern Peer-to-Peer Networking and Cloud Computing concepts. To exploit the full potential of these concepts, we primarily develop new Protocols, Services and Frameworks in order to simplify and automate the usage of Peer-to-Peer Networks and Cloud Computing.
