Abstract:
A device-specific value is reliably generated in a device. In a first component of the device, a first digital value is generated that is substantially dependent fabrication variation among like device. Redundancy information is computed based on the first digital value. A subsequent digital value is later generated in the first component of the device. The first digital value is then determined in a second component of the device from the subsequent digital value and the redundancy information.
