Research interests: Fault & side-channel attacks and countermeasures, cryptography, coding theory, stream ciphers (to learn more about the stream cipher Achterbahn-128/80  click on the link to the left).
I also further develop and maintain the Matpack C++ numerical and data visualization library. This is an ongoing effort since 1991. (Click on the link on the left side to enter the Matpack pages.)

Awards

  • 1st prize of the German IT-Security Prize 2012 for the research project Cryptographic Protocol with Inherent Side-Channel Resistance. The German IT-Security Prize of the Horst Goertz-Foundation has been awarded every two years since 2006. Its goal is to recognize and promote IT security "Made in Germany". Project submissions are not only judged according to their degree of innovation but also according to their economic potential.
    See
    Brochure of Award (original link to CASED) and Brochure of Award (local copy).
    The novel protocol is used in the CIPURSE™  open standard for public transportation of the OSPT Alliance.

  • Honoured with the Infineon Inventors Award for the Broadest Patent Portfolio 2005, March 8th, 2006.
