Abstract
A device is disclosed. The device includes a first memory circuit and a processing circuit. The first memory circuit stores identifications of the device that are used to generate first hash data through a hash algorithm. The processing circuit is coupled to the first memory circuit and selects at least one bit of each of the identifications in sequence to form a bit sequence, generates second hash data through the hash algorithm based on the bit sequence and authenticates the device according to a comparison between the first hash data and the second hash data.
