Aspects of the Development of Secure and Fault-Resistant Hardware

Designing "secure hardware" like a chip card controller, is a challenging task for hardware manufacturers: More and more attacks that are also more and more sophisticated generate a need for more and more countermeasures. Developers of these devices have to live with certain additional constraints and this does not make their life easier. In the following, the difficulties that the designer of such a system is confronted with, will be pointed out. This might give the scientific community some impression of the problems that would be interesting to be solved.
