Data Compression Drives the Internet. Here’s How It Works.
One student’s desire to get out of a final exam led to the ubiquitous algorithm that shrinks data without sacrificing information.
Why Mathematicians Re-Prove What They Already Know
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.
In Neural Networks, Unbreakable Locks Can Hide Invisible Doors
Cryptographers have shown how perfect security can undermine machine learning models.
The Year in Computer Science
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).
How Cryptography’s Quantum-Safe Future Will Work
Lattice cryptography promises to protect secrets from the attacks of far-future quantum computers.
New Entanglement Results Hint at Better Quantum Codes
A team of physicists has entangled three photons over a considerable distance, which could lead to more powerful quantum cryptography.
The Computer Scientist Who’s Boosting Privacy on the Internet
Harry Halpin wants our internet conversations to be more private. He’s helped create a new kind of network that might make it possible.
How Do You Prove a Secret?
Zero-knowledge proofs allow researchers to prove their knowledge without divulging the knowledge itself.
How Mathematical Curves Enable Advanced Communication
A simple geometric idea has been used to power advances in information theory, cryptography and even blockchain technology.
