Nick, I've been reading your search for a secure way to deal with boxes knowing each other. I as yet, have not found a hardware schematic or gone over the CPU itself to see if there are in intrinsic internals that might cure that problem. What we all need to look for is something unique to the hardware that would key tot he other DP's that this is a related hardware platform. This wouldn't guarantee that the accessing hardware is not villainous, but might help in identifying a 'friend or foe' situation.
I've always been somewhere where there is some kind of 'secure area' that we can trust, but the FB violates that basic principle and we may need to look at some kind of hardware arrangement. As I stated the CPU may have 'inside' information that we could use, discreetly to help us identify friends and reject foes. It seems like any software only approach needs some kind of 'friendly' environment to ensure the corrected things happen to ensure success with a new contact. This may be impossible without some kinds of 'assumptions' and you know what that leads to. Another thought is the obfuscation of the whole thing being encrypted with a partial key and shipping the whole key, but using some kind of algorithm to determine the 'part' we do use to decrypt the object. Just a thought, but I'll take some time this weekend and see if anything obvious in the CPU architecture would be of value. On another note: Put the DP down for a few days and maybe I'll have another epiphany! Never heard from anyone on how the monitor ROM in the DP commands work. Trying to get my WiFi to work on my Debian box as it would solve many problems. Unfortunately I can't find out how it detects and loads for WiFi cards.
