New Lattice Cryptanalytic Technique

A new paper presents a polynomial-time quantum algorithm for solving certain hard lattice problems. This could be a big deal for post-quantum cryptographic algorithms, since many of them base their security on hard lattice problems. A few things to note. One, this paper has not yet been peer...

Post-quantum Cryptography for the Go Ecosystem

filippo.io/mlkem768 is a pure-Go implementation of ML-KEM-768 optimized for correctness and readability. ML-KEM formerly known as Kyber, renamed because we can't have nice things is a post-quantum key exchange mechanism in the process of being standardized by NIST and adopted by most of the...

Enough Polynomials and Linear Algebra to Implement Kyber

I was once talking with a mathematician and trying to explain elliptic curve cryptography. Eventually, something clicked and they went "oh, that! I think there was a chapter about it in the book. You made a whole field out of it?" Yes, in cryptography we end up focusing on a very narrow slice of...

NIST Announces First Four Quantum-Resistant Cryptographic Algorithms

The U.S. Department of Commerce's National Institute of Standards and Technology NIST has chosen the first set of quantum-resistant encryption algorithms that are designed to "withstand the assault of a future quantum computer." The post-quantum cryptography PQC technologies include the...

The NSA Says that There are No Known Flaws in NIST’s Quantum-Resistant Algorithms

Rob Joyce, the director of cybersecurity at the NSA, said so in an interview: The NSA already has classified quantum-resistant algorithms of its own that it developed over many years, said Joyce. But it didnt enter any of its own in the contest. The agencys mathematicians, however, worked with NI...

Chinese Breakthrough in Quantum Computing a Warning for Security Teams

China’s top quantum-computer researchers have reported that they have achieved quantum supremacy, i.e., the ability to perform tasks a traditional supercomputer cannot. And while it’s a thrilling development, the inevitable rise of quantum computing means security teams are one step closer to...

More on NIST's Post-Quantum Cryptography

Back in July, NIST selected third-round algorithms for its post-quantum cryptography standard. Recently, Daniel Apon of NIST gave a talk detailing the selection criteria. Interesting stuff. NOTE: We're in the process of moving this blog to Wordpress. Comments will be disabled until the move it...
