摘要: A self-authenticating chip includes first and second memory regions storing, respectively, first and second authentication codes. The second memory region is adapted to be unreadable and unmodifiable by the chip or a chip reader. The chip also includes a comparator for providing an indicator of whether given input matches the second authentication code. The chip also includes an authentication circuit that is operable to read the first authentication code from the first memory region, present the first authentication code to the comparator, and in response to receiving an indicator from the comparator indicating that the first and second authentication codes match, unlock at least one of (i) a communication interface of the chip to allow data to be transmitted therethrough to a chip reader and (ii) a third memory region of the chip to allow data to be read therefrom.
