That's an even better pointer, thanks! This seems to be what I was looking for. If there are still other options I would like to know, though, to be able to compare prices and capabilities. Thanks, Matthias

This begs one question, and suggests one answer. The question is: why on earth would you want to do that? The answer is: you seem to be looking for a TPM. That's exactly the kind of chip you're after, and it's in the process of becoming a standard part on PC mainboards. -- Hans-Bernhard Broeker (broeker@physik.rwth-aachen.de) Even if all the snow were burnt, ashes would remain.

To do what: Replacing the smart card or requesting those features? ;-) The answer to the first one is mainly "reducing total costs" (before there is another question: to elaborate this I would have to go into details I do not want to disclose here). To answer the second one, I recommend the maxim application note 3675 (http://www.maxim-ic.com/appnotes.cfm/appnote_number/3675) where the basic concept is described.

No. If a TPM was the most cost-efficient and easy-to-implement solution for our requirements, then I would consider using a TPM. But as it seems, that is not the case... Regards, Matthias
