The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works. Whitfield Diffie and Martin ...

A new type of optical fiber filled with nothing but thin air has been found to be particularly effective for carrying out quantum key distribution (QKD), a security protocol that is in principle ...
