A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

Computer programmers have developed a new 'cutting-plane' algorithm, a general-purpose algorithm for solving optimization problems. The algorithm improves on the running time of its most efficient ...

Future quantum computers will need to be less powerful than we thought to threaten the security of encrypted messages.
