Abstract:
A root key of a computing device that is typically “burned” into the device hardware at time of manufacture is used to establish a master key and if desired a Transport Layer Security pre-shaped key, a WiFi configuration key, and application verification keys. The keys established from the root key are stored in a region of flash memory, and this region of flash memory is then encrypted using a random encryption code.
