Abstract
One or more hardware identity circuits (which may be reconfigurable) may be employed in a device or system in order to impose a tampering penalty, preferably without relying on battery-backed volatile memory to do so. The device or system may also include a cryptographic division and distribution (‘sharing’) of a secret internal to the device or system.
