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 desigin. 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. To find out more about our teaching in the winter term 2015/16, click here.

Workshop on RIFL

On November 23-25, a workshop on the development of the information-flow requirement specification language RIFL is taking place at the MAIS group. Six researchers from the Karlsruhe Institute of Technology and the German Research Center for Artificial Intelligence in Bremen are joining three researchers from MAIS to discuss future directions for RIFL and to extend the language.


Guest: Prof. Alessandro Aldini

Prof. Alessandro Aldini from University of Urbino, Italy, will visit MAIS from November 30 until December 4. He will give two talks on "Two Trust-based Applications for the Security of Mobile Devices" and on "Modeling and Verification of Trust and Reputation Systems" in the MAIS Graduate Seminar. Click here for more information about dates, times, and rooms.


Guest: Bart van Delft

Bart van Delft from Chalmers University of Technology will visit MAIS on October 26-29. He will give the talk "On Dynamic Security Policies: Specification, Security Conditions and Enforcement" on October 27 at 14:25 in room E302.
