Researchers created an optical system that encrypts information as a hologram that is scrambled when sent through a small container of liquid and then uses a neural network for decryption. WASHINGTON ...

Cryptography is something of a new field for Olivier Martin, who has been studying the optics of nanostructures for many years as head of the Nanophotonics and Metrology Lab EPFL’s School of ...

Once quantum computers become functional, experts warn, they could perform calculations exponentially faster than classical computers—potentially enabling them to destroy the encryption that currently ...

Researchers from Tokyo University of Science in Japan have developed a faster and cheaper method for handling encrypted data while improving security. Currently, homomorphic encryption and secret ...

In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode ...
