Doma: Good you're back...

In the posts you refer to I believe the issue is not where the TPM is located. I believe the issue is where to place the secure "USB Hub".

I was struck by these presentations as they might imply that, apart from the motherboard mounted 1.1/1.2 TPM, we'll see a "Trusted USB Hub". To me this may possibly dictate a programmable, multiple trust domain device with, for security reasons, it's own O/S. Does it not?

Will the keyboard become the "Trusted USB Hub"?


I refer to the following post:

Slide 20:

Multi-way Trust

- A trusted transaction only works when all the
participants trust each other to behave in certain
ways

- The customer, vendor, credit card company, etc., all are
participants


- This is the "doctrine of multiple Trustors": trust is
multi-way, not two way


- Anything/everything can be certified to be trusted by
anyone/anything


- Many "things" (HW or SW) will be certified by more than one entity

- Each entity may be measuring different facets of trust
