Abstract: A method for creating devices facilitating secure data transmission, storage and key management. At least two devices are each comprised of at least part of a physically unclonable function unit originally shared by the at least two devices on a single, monolithic original integrated circuit. The process includes physically segmenting the shared physically unclonable function unit between the at least two devices. The at least two devices which share the single, monolithic integrated circuit are physically separated into individual device units.
