This sounds like literally THE one master key? If google was ever made aware one device was lost or potentially compromised they would replace all devices?

- wmf 4y agoI doubt there's one. Probably each NIC has a separate master key. And they could reduce chance of compromise by loading the key at runtime and making it write-only.
- skyhawk 4y agoAs the PSP arch spec said, it seems each NIC has two master key. > each NIC has two 256-bit AES keys, called master keys, not shared with any hosts including its own, or with any other NICs. The master keys are "critical security parameters",which are kept ephemerally in on-NIC RAM, and must not be stored on any persistent medium.
