I mentioned several times over the past four years the AADS Chip Strawman that I had been working on (for strong authentication) http//www.garlic.com/~lynn/index.html#aads
I also gave a talk on it at the Intel Developer's Forum last year, including a claim that pretty much as it currently existed, it could do all the things that were requirement for trusted computing module. A copy of this presentation is also at the above URL (slides on assurance). there is now a process, brand, product and misc. other stuff http//www.asuretee.com/ There is also some code at source forge http//www.sourceforge.net/ and do a search on ecdsa.
