liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. A correctness error has been identified in the reference implementation of the HQC key encapsulation mechanism. Due to an indexing error, part of the secret key is incorrectly treat...

Google Chrome Switches to ML-KEM for Post-Quantum Cryptography Defense

Google has announced that it will be switching from KYBER to ML-KEM in its Chrome web browser as part of its ongoing efforts to defend against the risk posed by cryptographically relevant quantum computers CRQCs. "Chrome will offer a key share prediction for hybrid ML-KEM codepoint 0x11EC," David...

CVE-2024-37305 Buffer overflow in deserialization in oqs-provider

oqs-provider is a provider for the OpenSSL 3 cryptography library that adds support for post-quantum cryptography in TLS, X.509, and S/MIME using post-quantum algorithms from liboqs. Flaws have been identified in the way oqs-provider handles lengths decoded with DECODEUINT32 at the start of...

CVE-2024-37305

CVE-2024-37305 affects the oqs-provider (OpenSSL 3 post-quantum provider) where lengths decoded with DECODE_UINT32 at the start of serialized hybrid keys/signatures are unchecked, enabling out-of-bounds memory reads/writes that can crash or leak information. The issue does not affect plain/non-hy...

SUSE CVE-2024-36405

liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. A control-flow timing lean has been identified in the reference implementation of the Kyber key encapsulation mechanism when it is compiled with Clang 15-18 for -Os, -O1, and other...

CVE-2024-36405

CVE-2024-36405 affects the liboqs reference Kyber KEM implementation. A control-flow timing leak arises when the Kyber KEM is compiled with Clang 15–18 under certain options (including -Os and -O1), enabling a local attacker to measure decapsulation timings and recover the entire ML-KEM 512 secre...

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...
