Abstract
A system and device, including reconfigurable physical unclonable functions ('RPUFs') and threshold cryptography, use cryptographic and physical means of security. A plurality of reconfigurable physical unclonable functions ('RPUFs') and a memory are connected to a processor that is configured to derive information associating the RPUFs with cryptographic shares of a sensitive value, store such information in the memory, and reconfigure a RPUF upon powering up of the device such that information stored in the memory is not valid for the reconfigured RPUF.
