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.
Why Quantum Computers Might Not Break Cryptography
A new paper claims that a common digital security system could be tweaked to withstand attacks even from a powerful quantum computer.
Hacker-Proof Code Confirmed
Computer scientists can prove certain programs to be error-free with the same certainty that mathematicians prove theorems.
A Tricky Path to Quantum-Safe Encryption
In the drive to safeguard data from future quantum computers, cryptographers have stumbled upon a thin red line between security and efficiency.
A New Design for Cryptography’s Black Box
A recent cryptographic breakthrough has proven difficult to put into practice. But new advances show how near-perfect computer security might be surprisingly close at hand.
