Society depends on more and more information systems, which need to be secured against intentional disruption. The Distributed and Embedded Security group (DIES) forms the heart of the information security research at the University of Twente. We work on data security, network security and cybercrime prevention. Our research tools include cryptography, formal methods, machine learning and case studies. Results are applied to health and food management, critical control systems, and social and enterprise networks.
