Seeing as it comes out of the TCG, this is almost certainly the enabling hardware for Palladium/NGSCB. Its a part of your computer which you may not have full control over.
Please stop relaying FUD. You have full control over your PC, even if this one is equiped with a TCPA chip. See the TCPA chip as a hardware security module integrated into your PC. An API exists to use it, and one if the functions of this API is 'take ownership', which has the effect of erasing it and regenerating new internal keys.
Congratulations on your new baby. Working in the security business, paranoia is pretty much a job requirement. "What's the worst that could happen?" is taken seriously. The best that can happen with TCPA is pretty good - it could stop a lot of viruses and malware, for one thing. But the worst that can happen with TCPA is pretty awful. It could easily be leveraged to make motherboards which will only run 'authorized' OSs, and OSs which will run only 'authorized' software. And you, the owner of the computer, will NOT neccesarily be the authority which gets to decide what OS and software the machine can run. If you 'take ownership' as you put it, the internal keys and certs change, and all of a sudden you might not have a bootable computer anymore. Goodbye Linux. Goodbye Freeware. Goodbye independent software development. It would be a very sad world if this comes to pass. Peter Trei
