Doesn't this tie back strongly to the secure region logic? Sensing is one thing. Trusting the sensor input and what it unlocks is another.

- crazygringo 11mo agoNo, because they already do it for keyboards. There's zero reason they couldn't make it standalone. It's just the keyboard minus the rest of the keys.
- ggm 11mo agoSo they do a protocol bootstrap to link the sensor to the secure zone in some manner rooted in the trust region CA, and then do what they need without divulging secrets, over the USB bus? ok. that (or a more cogent version) would make sense. If you just package this button up, as a USB device, it's no different, if it can be bootstrapped as an input device "to" the secure zone.
