Abstract
Embodiments herein describe a 3D splintered physical unclonable function (3D-sPUF). In an example, an integrated circuit (IC) device includes multiple dies in a stacked configuration, and a PUF circuit generates a set of bits that is unique to the PUF circuit based on physical variations of elements of the PUF circuit, where the PUF circuit is distributed amongst two or more of the dies.
