PHYSICAL UNCLONABLE FUNCTION APPARATUSES AND MANUFACTURING METHODS BASED ON METAL NANOWIRE RANDOM NETWORK AND ENCRYPTION APPARATUSES USING THAT

摘要

The present invention relates to a physical copy protection security device and manufacturing method based on a metal nanowire random network, and an encryption device using the same. The method of manufacturing a physical copy protection security device according to an embodiment of the present invention comprises: Randomly forming nanowires to generate a metal nanowire random network, by laser welding at least one arbitrary region of the substrate on which the metal nanowire random network is generated, and forming a metal located in the laser-welded region And randomly connecting the nanowires, and generating an electrode array including a plurality of electrodes in a metal nanowire random network to which the metal nanowires are randomly connected.
