What’s the best way to solve hard problems? That’s the question at the heart of a subfield of computer science called computational complexity theory. It’s a hard question to answer, but flip it ...

Advanced Encryption Standard (AES) is a widely adopted and symmetric encryption algorithm standard used while securing data. It is a cryptographic standard, which was established by the US National ...

The original version of this story appeared in Quanta Magazine. In our increasingly digital lives, security depends on cryptography. Send a private message or pay a bill online, and you’re relying on ...

The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has finalized a set of encryption algorithms designed to withstand cyberattacks from quantum computers. These ...

Cryptographers want encryption schemes that are impossible for tomorrow’s quantum computers to crack. There’s only one catch: they might not exist. When we check email, log in to our bank accounts, or ...

Researchers said it was the first time a quantum computer “posed a real and substantial threat” to encryption, but multiple limitations still hamper a full-scale hack. Chinese researchers using a ...

Lightweight electronics, meet the heavyweight champion for protecting your information: Security experts at the National Institute of Standards and Technology (NIST) have announced a victor in their ...
