Acknowledgements
This work could never have happened without the support and assistance of many people. Only a
few of them can be mentioned here.
First of all, I would like to thank Prof. Dr.-Ing. Ralf Steinmetz for his supervision, invaluable
advice, and encouragement. My special thanks go also to Prof. Dr.-Ing. Heinz Thielmann and
Prof. Dr. Claudia Eckert for their guidance and the fruitful environment, in which this thesis could
flourish during the past years. Many thanks to Prof. Dr. Kurt Geihs for acting as a co-reporter.
I would like to thank all those colleagues at the Fraunhofer Institute for Secure
Telecooperation (FhG-SIT) in Darmstadt, who are taking care of the pleasant and friendly
atmosphere without which the success of such a thesis is hardly impossible. I am also thankful to
all those people, in particular the members of the COR research department, who have backed me
up during the past few months while I was trying to finish this work.
This thesis has clearly benefited from developments and results in various projects I was
involved in at FhG-SIT. Knut Bahr and Heinz-Jürgen Burkhardt do have a very special part in the
success of this thesis, as they have stimulated this work and contributed valuable ideas, proposals,
and comments throughout many fruitful discussions. I am especially thankful to Mario Hoffmann,
Sven Türpe, and Ruben Wolf for the excellent co-operation.
Special thanks go also to the VOTEC and UNITE teams, as the have contributed to the
success of this thesis with their constructive criticism and numerous discussions. Daniel Tietze
deserves some thanks for the excellent and fruitful collaboration within the context of the
Poliwork project and beyond. Many thanks to Michael Zapf and Klaus Herrmann for their great
support with respect to their multi-agent development environment AMETAS, from which the Co-
operation Platform has benefited. Thanks go to Thomas Kunkelmann for the joint work on
scalable partial encryption methods and the implementation of a secure multimedia conferencing
gateway.
Many thanks to all students who have contributed to the Co-operation Platform while I was
supervising their master’s thesis or looking after their practical trainings and internships. In place
of all others, I would like to emphasize Thomas Blecher, Matthias Guckler, Jörg Hähner, Peter
Hörmann, Max Larsson, Hüsnü Turkac and the software engineering teams Mind &Magic, Lynx,
and Multiculture.
Special thanks go to Ludger and Volkmar Hovestadt, Gerd Bonnet, Stefan Steuerwald, Jupp
Gauchel, and Eric Giese for the stimulating discussions on the architectural aspects of Co-
operative Buildings and their share to the exciting research and development of the
RoomComputer in particular.
I am thankful to Natalie Boehm for reading this thesis, correcting linguistic mistakes here a
and there, and for making an effort to positively influence my style of writing.
Finally, special thanks go to Marie-Luise for supporting me all the time and in particular for
catching all the silly mistakes that managed to slip. She deserves more thanks than anybody else
does, because she is the pillar I can always rely on and she always treaded on my toes to get this
work finished. Nevertheless, I have benefited from her well-founded knowledge in the area of IT-
Security. This thesis is dedicated to her.
