Researchers Use Natural Silk Fibers to Generate Secure Keys for Strong Authentication

A group of academics at South Korea’s Gwangju Institute of Science and Technology (GIST) have utilized natural silk fibers from domesticated silkworms to build an environmentally friendly digital security system that they say is “practically unbreachable.”
“The first natural physical unclonable function (PUF) […] takes advantage of the diffraction of light through natural microholes in native
