Title: GENERATING A UNIQUE RESPONSE TO A CHALLENGE
Abstract:
According to a first aspect of the invention, there is provided a device for generating a unique response to a challenge, the device comprising: a plurality of structures, each structure exhibiting quantum mechanical confinement, and each structure being arranged to provide a unique response when challenged with an electrical measurement, the unique response being linked to the atomic makeup of the structure that defines the quantum mechanical confinement; the device being arranged to facilitate a challenge of at least two structures of the plurality in electrical combination to generate the unique response, by facilitating an electrical measurement of an output of theat least two structures of the plurality in electrical combination;the unique response being derivable from the electrical measurement.
