Block ciphers are invertible symmetric key cryptographic algorithms. Here, symmetric means that the same cryptographic key is used to both encrypt and decrypt messages. The key is used to transform ...

OpenAI’s bumper crop of 722 math papers wowed and worried the research community—and cryptographers are split over whether ...

A quantum-resistant cryptography algorithm that was under consideration as an official US standard has been taken out of the running after an Anthropic security model helped find a flaw that rendered ...

A stream cipher is an encryption method in which data is encrypted one byte at a time. In this method, a cryptographic key and algorithm are applied to each binary digit in a plaintext data stream to ...

Even as federal agencies move their most sensitive systems to new forms of encryption following an order from the White House ...

OpenAI’s release last Tuesday of more than 300 math results it says an internal model solved has sparked concern among some ...

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 ...

NIST’s first three PQC standards cover ML-KEM for key establishment and ML-DSA and SLH-DSA for digital signatures. The standards are designed to protect information against attacks involving future ...

There’s little doubt that some of the most important pillars of modern cryptography will tumble spectacularly once quantum computing, now in its infancy, matures sufficiently. Some experts say that ...

Two years ago, researchers in the Netherlands discovered an intentional backdoor in an encryption algorithm baked into radios used by critical infrastructure–as well as police, intelligence agencies, ...
