Abstract
It is made possible to prevent 'spoofing' and incur no additional management cost as effectively as possible. An authenticated device includes: at least one authenticated element that generates an output signal with characteristics spontaneously varying, at the time of manufacturing, with respect to a continuous input signal. The characteristics of the authenticated element are used as information unique to an individual.
