Hi Dig

It seems to me that all Microsoft has done is create a way in which Windows 8 can leverage the existing TPM management software for use on that discrete machine with that same TPM. Thus, Windows 8 on a machine with an Infineon TPM will use the included Infineon software to produce the keys and hashes needed to perform operations like a secure boot,.. but only on that machine. The keys are backed up on a USB drive that is used for that machine only. Likewise for an Broadcom TPM which uses the Wave management software.



Unless I have missed something, (and that is entirely possible)Windows 8 cannot enable secure communications such as reading encryption keys between the Broadcom TPM machines and Infineon machines without Wave's software. This is the valuable part of "interoperability." It is this capability, enabled by Wave's encryption "smoothing" algorithm that will make key migration possible with all of the benefits that accompany, like a bank being able to read encryption keys from both Infineon and Broadcom machines-as well as keys from all other types of trusted modules, like from "Trustzone."

Awk, please correct me if I am wrong.
