Modeling and Analysis of Information Systems


The aim of our research is to make software-based systems more trustworthy (i.e. secure, safe, and correct) than they are today. As software engineering is a complex and error-prone task, we employ formal methods for reasoning about information systems and critical system properties. We investigate software systems on the level of code (source code and machine code) as well as on the level of more abstract system specifications. This allows us to provide support for different stages of software development. More details can be found in the Research and Projects sections.

We coordinate the DFG priority program RS3 (Reliably Secure Software Systems) that is lead by Prof. Dr.-Ing. Heiko Mantel since 2010. This involves the organization of multiple events each year, most prominently the annual meeting and the staff meeting. Within RS3, our scientific focus is on driving forward research on information-flow security for concurrent programs, on a security-certifying app store for Android devices, and the security-requirement specification language RIFL. More details can be found in the RS3 section.

We are involved in four further third-party funded research projects involving multiple principle investigators. Within the DFG collaborative research center CROSSING, we are developing techniques and tools for detecting, assessing, and mitigating timing-side channels in cryptographic implementations. Within CASED, we are focusing on dynamic approaches to usage control based on the concept of service automata. Within EC-SPRIDE and CRISP, we are creating solutions for security by design. More details can be found in the Projects section.

Parts of our research are funded by the BMBF (German Federal Ministry of Education and Research), by the DFG (German Research Foundation), by the EU (European Union), by the Land Hessen within LOEWE (Landes-Offensive zur Entwicklung Wissenschaftlich-ökonomischer Exzellenz), and by industry.

We are the proud recipients of three best-paper awards in the last 5 years.


We are offering a portfolio of lectures, integrated courses, lab courses, and seminars. Find out more about our teaching in the winter term 2016/17 and summer term 2017.

If you are interested in writing a Master or Bachelor thesis with us, you can find more information in the Theses section.
