Abstract:
The disclosed embodiments relate to secure booting of memory device. The disclosed embodiments generate measurement data associated with a memory device. Next, the disclosed embodiments read a golden measurement from a secure location in the memory device, the golden measurement generated based on a version of the data associated with the memory device, and therefore it is unique to the device. The disclosed embodiments validate the golden measurement value using a public key and determine whether the golden measurement is equal to the measurement data. The golden measurement value can also be saved in a write protected area which can only be changed by a secure write command, therefore, it is imutable by others. Finally, the disclosed embodiments continue a boot process when the golden measurement is equal to the measurement data.
