AUTHENTICATION USING GRAPHENE BASED DEVICES AS PHYSICAL UNCLONABLE FUNCTIONS

摘要

A method of manufacturing a secure device having a physical unclonable function includes providing a first graphene layer, providing a second graphene layer and applying a variability enhancement to at least one of the first graphene layer and the second graphene layer such that a measurable property is different for each of the first graphene layer and the second graphene layer. The physical unclonable function is represented by at least the first and second graphene layers. In still another embodiment, a method of manufacturing a secure device having a physical unclonable function includes providing an integrated circuit comprising at least one graphene layer and including a measurement circuit in the integrated circuit that is configured to measure at least one property of the at least one graphene layer for authenticating the secure device. The at least one graphene layer represents the physical unclonable function.
