Encryption, at its core, is similar to those decoder rings you played with when you were younger. You have a message, you encode it using a secret cipher, and only other people with the cipher can ...

In quantum encryption, one encodes information in quantum states. Just as one can measure quantum states to decode a message, one can measure quantum states to find out information about an object.

Though US Law may prohibit the NSA from collecting our phone data (or demanding encryption keys) without a court order, the ability to decode these encrypted conversations own their own means they ...

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate.
