Abstract
A physical unclonable function device, an encryptable electronic device, and a process for fabricating the physical unclonable function device are described. In an implementation, a physical unclonable function device includes an integrated circuit device including an active layer, the active layer including an electrode array with multiple electrodes; and a physical unclonable function coating disposed on the active layer, wherein the physical unclonable function coating includes a physical unclonable material arranged in a random configuration.
Claims3
A physical unclonable function device, comprising:
- an integrated circuit device including an active layer, the active layer including an electrode array with multiple electrodes;
- a physical unclonable function coating disposed on the active layer, wherein the physical unclonable function coating comprises a dielectric material, and wherein the physical unclonable function coating includes a physical unclonable material arranged in a random configuration;
- wherein the physical unclonable function coating includes a glass material and the physical unclonable material includes glass beads;
- and
- a distinct capacitance between at least two electrodes of the electrode array is used as a unique identifier in the physical unclonable function device depending on a density of the physical unclonable function material and a distance between the at least two electrodes of the electrode array.
