Cryptography

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.

Two researchers have broken an encryption protocol that many saw as a promising defense against the power of quantum computing.

Cryptographers want to know which of five possible worlds we inhabit, which will reveal whether truly secure cryptography is even possible.
