Abstract
Methods and systems for generating an identifier includes testing an operational characteristic for each device in an array of pairs of devices. Each pair of devices includes a first device and a second device. The first device of each pair has a higher inter-device uniformity for the operational characteristic than the second device of the pair. The operational characteristic between the first device and the second device is compared for each pair of devices to generate a respective identifier bit for each pair of devices. An identifier is generated from the identifier bits.
