Abstract
A system and method for providing a physically unclonable function (PFU) is described. In operation, the method includes applying a domain wall shift pulse challenge to a plurality of nanowires of a domain wall memory (DWM) array, wherein the nanowires of the domain wall memory (DWM) array have process induced variations, resulting in pinning potentials which affect the velocity of the domain walls along the length of the nanowires. Following the application of the domain wall shift pulse, the response to the challenge is determined by measuring the response of the plurality of nanowires of the domain wall memory to the applied domain wall shift pulse challenge to provide a physically unclonable function (PUF) for the integrated circuit.
