Abstract
Embodiments of the present invention provide a chip authentication system using multi-domain intrinsic identifiers. Multiple intrinsic identifiers taken from multiple domains (areas or sections of the chip) are compared against the intrinsic identifiers collected during the manufacture of the chip. If at least one intrinsic identifier matches those collected during manufacture, the chip may be designated as authentic.
