Concealable physically unclonable function chip with a memristor array.

ABSTRACT: A physically unclonable function (PUF) is a creditable and lightweight solution to the mistrust in billions of Internet of Things devices. Because of this remarkable importance, PUF need to be immune to multifarious attack means. Making the PUF concealable is considered an effective countermeasure but it is not feasible for existing PUF designs. The bottleneck is finding a reproducible randomness source that supports repeatable concealment and accurate recovery of the PUF data. In this work, we experimentally demonstrate a concealable PUF at the chip level with an integrated memristor array and peripherals. The correlated filamentary switching characteristic of the hafnium oxide (HfO_x)-based memristor is used to achieve PUF concealment/recovery with SET/RESET operations e
