Abstract
A device and a method for implementing a physically unclonable function is disclosed. In one aspect, the device includes at least one electronic structure including a dielectric. A conductive path is formed at a random position through the dielectric due to an electrical breakdown of the dielectric, or the electronic structure is adapted for generating an electrical breakdown of the dielectric such that the conductive path is formed through the dielectric at a random position. The at least one electronic structure is adapted for determining a distinct value of a set comprising at least two predetermined values. The distinct value is determined by the position of the conductive path through the dielectric.
