You're correct. My hat's off to the great DD'ers of the day. Good sleuthing!

I looked but didn't find anything. Thought I would find something for Eamon's list with the new Sharp mm20 laptop but no TPM it seems. Expected one.

Yes, I was well aware of SKS's discussion as quoted in the eeTimesUK re: the market demanding a programmable chip (TPM). What always surprised me about that was that I don't think anybody here had considered programmability in that context before...ie. being able to reprogram the chip to thwart hackers. We had always thought of programmability as it pertains to the the processing of trusted apllication (trustlets) in Embassy.

I am still trying to understand if programmability of the TPM within the LaGrande/NGSCB architecture is an enhancement providing additional functionality, or if it would be redundant to LaGrande/NGSCB?

In the context of what SKS was quoted as saying in eeTimes, it would seem that a programmable TPM might enhance LaGrande/NGSCB.

I had meant to go back over the NGSCB whitepaper and then review Embassy to see if I could understand once and for all if LaGrande/NGSCB will be programmable in the same sense that Embassy is as that pertains to the processing of trustlets.

I was in a hurry this morning and was not able to fully digest your post first time around.

Great points!

The more interesting topic is how one would provide technology providing a secure execution environment for inexpensive consumer platforms other than PC's and/or cell phones.

For a long time I had been considering SOC's (system-on-a-chip) providing something like E2100 functionality.

However, I believe the recent SafeNet announcement at 3GSM and RSA that SafeNet will develop a TPM capability for Texas Instruments and ARM based chips and processors is a major step. Since these will be based on TCG standards, then Wave's TCG based products and infrastructures should be capable of supporting these platforms as well. The annual volumes of devices shipped based on these types of chips and processors is several time greater than the PC platform volumes.
