If the carrier controls the TPM, it isn't TC. It's a secure device that is still controlled by a third party.


Well no, after taking ownership of the TPM, the carrier provisions the device owner ie. you or me into the TPM as the only authorized device which is immutable. It has the same result as a PC TPM ie. only the device owner is provisioned to the TPM, nothing else.

I'm not sure why the TCG procedure has the carrier taking TPM ownership on behalf of the user. There has to a technical basis for it.

But the carrier does have to perform the take TPM ownership process (on behalf of the device owner). Could this, and not MS releasing their API, be the missing link in Windows Phone 8? If an enterprise customer wants to deploy TPM-enabled Windows phones. I assume the carrier has to provision the TPM activations.
