Three researchers have found a long-sought way to pull information from large databases secretly, moving us closer to fully private internet searches.
Thirty Years Later, a Speed Boost for Quantum Factoring
Shor’s algorithm will enable future quantum computers to factor large numbers quickly, undermining many online security protocols. Now a researcher has shown how to do it even faster.
The Cryptographer Who Ensures We Can Trust Our Computers
Yael Tauman Kalai’s breakthroughs secure our digital world, from cloud computing to our quantum future.
In Neural Networks, Unbreakable Locks Can Hide Invisible Doors
Cryptographers have shown how perfect security can undermine machine learning models.
How Cryptography’s Quantum-Safe Future Will Work
Lattice cryptography promises to protect secrets from the attacks of far-future quantum computers.
‘Post-Quantum’ Cryptography Scheme Is Cracked on a Laptop
Two researchers have broken an encryption protocol that many saw as a promising defense against the power of quantum computing.
Cryptographers Achieve Perfect Secrecy With Imperfect Devices
For the first time, experiments demonstrate the possibility of sharing secrets with perfect privacy — even when the devices used to share them cannot be trusted.
Computer Scientists Achieve ‘Crown Jewel’ of Cryptography
A cryptographic master tool called indistinguishability obfuscation has for years seemed too good to be true. Three researchers have figured out that it can work.
Cryptography That Is Provably Secure
Researchers have just released hacker-proof cryptographic code — programs with the same level of invincibility as a mathematical proof.
