Title:
STRUCTURES FOR PHYSICAL UNCLONABLE FUNCTION USING SPONTANEOUS CHIRAL SYMMETRY BREAKING AND METHOD OF PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2023/113508
Kind Code:
A1
Abstract:
The present invention relates to structures for a physical unclonable function using spontaneous chiral symmetry breaking and a method of preparing same. More specifically, by using a chiral photonic crystal, in which chiral symmetry breaking occurs, to form an unclonable chiral random pattern that can be observed with an optical microscope and a mobile phone camera, and using the chiral random pattern in a physical unclonable function (PUF), it is possible to produce, through existing photo-lithography methods, a desired pattern that is highly secure, has high information density, and exhibits high performance in properties such as reproducibility, uniqueness, high information density, high recognition ratio, unpredictability, or reconfigurability.
