Abstract: During an initial bootup in a bootloader of an SOC, a random number that is unique to the device is stored in secured storage. During a first bootup, a two-dimensional random key is stored in secure storage for encoding the ENV parameters. During a second (subsequent) bootup, the ENV parameters that are current in unsecured storage are compared against the ENV parameters that previously existed in order to identify a mismatch. A remediation security action can be taken responsive to a mismatch between the baseline digest and a dynamic digest. Ultimately, an operating system can be loaded in the bootloader.
