Cryptography

One student’s desire to get out of a final exam led to the ubiquitous algorithm that shrinks data without sacrificing information.

It’s been known for thousands of years that the primes go on forever, but new proofs give fresh insights into how theorems depend on one another.

Cryptographers have shown how perfect security can undermine machine learning models.

Computer scientists this year learned how to transmit perfect secrets, why transformers seem so good at everything, and how to improve on decades-old algorithms (with a little help from AI).

Lattice cryptography promises to protect secrets from the attacks of far-future quantum computers.

A team of physicists has entangled three photons over a considerable distance, which could lead to more powerful quantum cryptography.

Harry Halpin wants our internet conversations to be more private. He’s helped create a new kind of network that might make it possible.

Zero-knowledge proofs allow researchers to prove their knowledge without divulging the knowledge itself.

A simple geometric idea has been used to power advances in information theory, cryptography and even blockchain technology.
