Apple iOS 17.4: iMessage Gets Post-Quantum Encryption in New Update
Useful quantum computers aren’t a reality—yet. But in one of the biggest deployments of post-quantum encryption so far, Apple is bringing the technology to iMessage. #apple #computing #encryption #privacy #quantum #security
Chinese researchers claim to have broken RSA with a quantum computer. Experts aren’t so sure.
Researchers in China claim to have reached a breakthrough in quantum computing, figuring out how they can break the RSA public-key encryption system using a quantum computer of around the power that will soon be publicly available. Breaking 2048-bit RSA — in other words finding a method to consistently and quickly discover the secret prime numbers underpinning the algorithm — would be extremely significant. Although the RSA algorithm itself has largely been replaced in consumer-facing protocols, such as Transport Layer Security, it is still widely used in older enterprise and operational technology software and in many code-signing certificates.
A group of Chinese researchers have just published a paper claiming that they can—although they have not yet done so—break 2048-bit RSA. This is something to take seriously. It might not be correct, but it’s not obviously wrong.
