Enhancing NTRUEncrypt Security Using Markov Chain Monte Carlo Methods: Theory and Practice

This paper presents a novel framework for enhancing the quantum resistance of NTRUEncrypt using Markov Chain Monte Carlo MCMC methods. We establish formal bounds on sampling efficiency and provide security reductions to lattice problems, bridging theoretical guarantees with practical...

Claude Code Can Debug Low-level Cryptography

Over the past few days I wrote a new Go implementation of ML-DSA, a post-quantum signature algorithm specified by NIST last summer. I livecoded it all over four days, finishing it on Thursday evening. Except… Verify was always rejecting valid signatures. $ bin/go test crypto/internal/fips140/mlds...

curl: curl built with GnuTLS backend defaults to weak crypto parameters

Summary: Curl configured with GnuTLS backend --with-gnutls defaults using "NORMAL" as the base level of the library cryptographic security. From GnuTLS documentation: The message authenticity security level is of 64 bits or more, and the certificate verification profile is set to GNUTLSPROFILELOW...

CVE-2025-58187 Quadratic complexity when checking name constraints in crypto/x509

Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains...

Signal’s Post-Quantum Cryptographic Implementation

Signal has just rolled out its quantum-safe cryptographic implementation. Ars Technica has a really good article with details: Ultimately, the architects settled on a creative solution. Rather than bolt KEM onto the existing double ratchet, they allowed it to remain more or less the same as it ha...

CVE-2025-40062 crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs

In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/qm - set NULL to qm-debug.qmdiffregs When the initialization of qm-debug.accdiffreg fails, the probe process does not exit. However, after qm-debug.qmdiffregs is freed, it is not set to NULL. This can lead to a...

Quantum-Resistant Networks Using Post-Quantum Cryptography

Quantum networks rely on both quantum and classical channels for coordinated operation. Current architectures employ entanglement distribution and key exchange over quantum channels but often assume that classical communication is sufficiently secure. In practice, classical channels protected by...
