Cryptography: welcome to my world of confidentiality, integrity and availability. For the past 20 years, I have had the privilege of being part of the steady evolution of how organizations encrypt ...

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto ...

Quantum computing capabilities are accelerating, pushing traditional encryption methods closer to obsolescence. In response, cryptographers and security professionals are advancing post-quantum ...

The original version of this story appeared in Quanta Magazine. In our increasingly digital lives, security depends on cryptography. Send a private message or pay a bill online, and you’re relying on ...

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the ...

Before we move into the meat of this article, let’s define a couple terms related to cryptography. The syllable crypt may make you think of tombs, but it comes from a Greek word that means “hidden” or ...

Reports began surfacing in October that Chinese researchers used a quantum computer to crack military-grade AES 256-bit encryption. Those reports turned out to be wrong, but that did little to dampen ...

In their study, the team demonstrated that the existence of these proofs depends on the existence of a certain cryptographic primitive called a one-way puzzle. By integrating these methods, the team ...

It’ll still be a while before quantum computers become powerful enough to do anything useful, but it’s increasingly likely that we will see full-scale, error-corrected quantum computers become ...
