Physically unclonable functions are the most secure technology to keep a static cryptographic key in a device due to its unclonable and volatile properties, where PUF responses disappear when the power is off. These make a PUF-based key is intrinsically secure against reverse engineering. Though the PUF itself is secure, its integration into a system must be carefully designed to keep its security. This paper presents SAMPUF™ design approach and its integration with security systems.
