Abstract:
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.

Claim (Index 36):
A self-authenticating integrated circuit chip comprising:\n a first memory region storing a first authentication code, in encrypted form; a second memory region storing a second authentication code; a comparator circuit on the integrated circuit interconnected to at least said second memory region for providing an indicator of whether a given input to said comparator circuit matches said second authentication code stored in said second memory region; wherein said second authentication code within said second memory region cannot be extracted or modified by said integrated circuit or a chip reader and may only be accessed by said comparator to compare the given input to said comparator to said second authentication code; and an authentication circuit on the integrated circuit interconnected to said comparator and at least one of said one or more memory circuits wherein said authentication circuit is operable to:\n read said first authentication code in encrypted form from said first memory region; \n decrypt said first authentication code; \n present said first authentication code as decrypted to said comparator; and \n in response to receiving an indicator from said comparator indicating that said first authentication code as decrypted matches said second authentication code unlock a communication interface of said chip to allow data to be transmitted therethrough to a chip reader or unlock a third memory region of the integrated circuit.
