Encryption is less secure than we thought

Information theory—the discipline that gave us digital communication and data compression—also put cryptography on a secure mathematical foundation. Since 1948, when the paper that created information theory first appeared, ...

Protecting light communication with random objects

Researchers from the Complex Photonic Systems (COPS) group used two layers of random materials to encrypt and decrypt a message sent via light communication. With that, they hid the sender and receiver simultaneously, and ...
