Abstract
According to an aspect of the present principles, there is provided a method and an authentication apparatus. The method includes arranging a plurality of graphene resistors in parallel or series. The method further includes forming a unique identification code based on respective temperatures emanating from or respective voltages output from the plurality of graphene resistors when the plurality of graphene resistors are in a powered state.
