Hi Dig,

The point is the process.

If a user can recover the key to their own device, no problem so long as their identity can be authenticated.

If a third party such as law enforcement can get a subpoena to access your device, that is permissible under probable cause and practical due to the key archive. That is targeted surveillance and I thing that is a balanced approach between the needs of security and privacy.

If a third party such as NSA can grab the key archive then it can continuously access your machine, store its content and communications and clearly associate the use of the machine with the user. SOD seems to have been set up to share data between interested government folks in acronym city such as DEA, FBI, CIA, IRS etc. That is something new and unpleasant. Non-terrorist, non-criminal individuals have legitimate secrets from the government.

TCG was originally sold on the concept there is no government back door. That looks increasingly nonsensical.

I am befuddled by the notion of novelty in this whole back door thingy.

Some time ago somebody lost access to a TPM secured machine, can't remeber who, can't remember when, but the pointis the critical password they needed to unlock key access had been lost and not backed up.

They called Dell.

Dell asked for a serial number.

Dell served them a magic bullet. They got in.

Their brick became a computer again.

The point that a supplier could walk around the user and re-access a machine was thing well established for me at that point and some musing about it occurred on these various boards. The front was hardened, the back accessible.
