Overview The research group IT-Security was founded in August 2008 as part of the research cluster “UMIC – Ultra high-speed Mobile Information and Communication”. By now the group consists of an associate professor, three research assistants, and 9 student researchers. The group studies and teaches security and privacy problems and solutions in different types of communication networks with a main focus on securing wireless networks. Our newly developed security protocols typically make use of recent developments in cryptography and make new theoretical results directly usable in practice. In particular, we are interested in the evaluation of the design and implementation of security architectures for newly evolving wireless technologies such as the Evolved Packet System, or the new Bluetooth standard. We develop new solutions to securely support mobility in heterogeneous networks such as multi-domain RFID systems, roaming between different WLAN operators, and key handling solutions for mobility between different access technologies. These solutions include authentication, authorization, and accounting support, as well as efficient key handling and re-authentication. A newer development in the area of wireless networks are wireless mesh networks in which mobile clients connect to so-called mesh routers that in turn are wirelessly connected to other mesh routers, which may then act as a gateway to other networks. Mesh networks pose new security challenges, mainly due to their multi-hop nature and the problem that nodes may be captured and start acting maliciously. We develop new approaches for secure key management and to identify malicious nodes. In the area of privacy we work on privacy-preserving distributed multi-party applications some of which are targeted at mobile devices. For this area of research we won a DFG research grant in August 2010. Finally, we also work on the collection and analysis of (mobile) malware and on botnet protection. In particular we support the MW-Collect Alliance, and have research and development contracts with Nokia Siemens Networks and the National High-tech Crime Unit of the Netherland’s Police. In addition, in 2010 we helped to secure the BMBF-funded research project ASMONIA together with our partners Nokia Siemens Networks, Fraunhofer Institut für sichere Kommunikationstechnologie, EADS Deutschland GmbH, ERNW GmbH, and Augsburg University of Applied Science. With respect to teaching, the group offers a one-year cycle of four lectures, a seminar, and a laboratory course. This cycle was developed from scratch in 2008/2009. During winter terms we typically offer the lectures IT-Security 1 and Security in Mobile Communications. IT- Security 1 provides an introduction to cryptography and focuses on network security, while Security in Mobile Communications covers the security architectures of attacks against already standardized wireless technologies such as mobile phone networks, wireless local area networks, or Bluetooth. In addition, we offer a seminar on selected topics in mobile security during winter terms. In the summer we offer the lectures IT-Security 2, which focuses on system security and a lecture on Security and Cooperation in Wireless Networks, which covers new developments in wireless technologies such as sensor networks or vehicular networks. Also, in summer terms we offer a security lab in which students learn how to deal with practical attacks against wireless as well as wired networks and systems. 423
