‘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.
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.
