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 computers powerful enough to break widely used public-key encryption aren’t here yet, but migration won’t be as simple as swapping in a new tool.

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

Classical public-key cryptography derives its security from integer factorisation. Diagram by Venus Kolhi. Quantum computers bring exponential computing power, ultrafast calculations, advanced ...

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 ...

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 ...

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 ...

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 ...
