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 ...

The National Institute of Standards and Technology (NIST) has selected a group of cryptographic algorithms to secure the Internet of Things (IoT) devices and the related tiny sensors and actuators.

There is no doubt that quantum computers will play a significant role in helping the world solve complex challenges not possible on current classical computers. However, quantum computers also pose a ...

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 ...

Within a decade, the growth of powerful quantum computers will lead to a new era in security, in which once-impenetrable public-key techniques like RSA and ECC will fall to higher levels of brute ...

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics. In our increasingly digital lives, ...

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 ...

The FIDO2 industry standard adopted five years ago provides the most secure known way to log in to websites because it doesn’t rely on passwords and has the most secure form of built-in two-factor ...
