Abstract
This document describes techniques for authenticating an identity of a semiconductor component using a physical identifier. In some aspects, a physical identifier comprised of a region of features located indiscriminately within a surface of an encapsulated semiconductor component is fabricated. The physical identifier is then mapped. The map is then stored for use when authenticating the identity of the semiconductor component.
