摘要：A device, including: an unsecure non-volatile memory; a secure device including:a processor; and a secure non-volatile memory; wherein the secure device is configured
to: calculate a TMC value from an offset and a base value; store a TMC version value in the secure non-volatile memory and the insecure non-volatile memory, wherein the TMC version value is updated when TMC value is incremented the first time after the secure device is powered up; store the base value in the unsecure non-volatile memory; store the offset value in the unsecure non-volatile memory when the secure device is in a system power down state; store the offset value in the secure non-volatile memory when the secure device is in a rescue state; and store a TMC link value in the unsecure memory, wherein the TMC link value is based upon the base value and TMC version value stored in the unsecure memory.
