Scientists at Northwestern University say they have harnessed the properties of light to encrypt information into code that can be cracked only one way: by breaking the physical laws of nature. This ...

Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text data ...

Threats to computer and network security increase with each passing day and come from a growing number of sources. No computer or network is immune from attack. A recent concern is the susceptibility ...

Quantum computers stand a good chance of changing the face computing, and that goes double for encryption. For encryption methods that rely on the fact that brute-forcing the key takes too long with ...
