SYSTEM AND METHOD FOR RESTORATION OF A TRUSTED SYSTEM FIRMWARE STATE

Operations include restoring a trusted system firmware state. A system stores a set of self-contained secure code in a secure code store. The system stores a set of operational code in an operational code store. The system executes the secure code or the operational code upon system start up, depending whether the system is configured in a secure mode, or in a normal operational mode. When the system is configured in secure mode, the system executes the secure code. In secure mode, the system also overwrites a current version of the operational code stored in the operational code store with a replacement version of the operational code referenced by the secure code. When the system is configured in normal operational mode, the system executes the operational code. During normal operation, the secure code store is electrically isolated.
