Zusammenfassung: | A secure one-time programming undo system includes a component and a component configuration system. A one-time programming subsystem in the component configuration system provides the component with personality configuration information that configures the component to perform component operations, and performs a one-time programming operation that configures a component engine in the component to deny modification requests to modify the personality configuration information. A one-time programming undo subsystem in the component configuration system performs a one-time programming undo authentication operation, and transmits a one-time programming undo instruction that is associated with the one-time programming undo authentication operation to the component, with the one-time programming undo authentication operation configured to authenticate the one-time programming undo instruction to the component such that the component executes the one-time programming undo instruction that reconfigures the component engine in the component to allow modification requests to modify the personality configuration information. |
