PQC-Enhanced QKD Networks: A Layered Approach

We present a layered and modular network architecture that combines Quantum Key Distribution QKD and Post-Quantum Cryptography PQC to provide scalable end-to-end security across long distance multi-hop, trusted-node quantum networks. To ensure interoperability and efficient practical deployment,...

Signature Placement in Post-Quantum TLS Certificate Hierarchies: An Experimental Study of ML-DSA and SLH-DSA in TLS 1.3 Authentication

Post-quantum migration in TLS 1.3 should not be understood as a flat substitution problem in which one signature algorithm is replaced by another and deployment cost is inferred directly from primitive-level benchmarks. In certificate-based authentication, the practical effect of a signature fami...

Google Wants to Transition to Post-Quantum Cryptography by 2029

Google says that it will fully transition to post-quantum cryptography by 2029. I think this is a good move, not because I think we will have a useful quantum computer anywhere near that year, but because crypto-agility is always a good thing. Slashdot thread...

Merkle Tree Certificate Post-Quantum PKI for Kubernetes and Cloud-Native 5G/B5G Core

Post-quantum signature schemes such as ML-DSA-65 produce signatures of 3,309 bytes and public keys of 1,952 bytes over 50 times larger than classical Ed25519. In TLS-authenticated environments like Kubernetes control planes and 5G Core networks, where every inter-component connection is mutually...

EUVD-2026-18466

The leancrypto library is a cryptographic library that exclusively contains only PQC-resistant cryptographic algorithms. Prior to version 1.7.1, lcx509extractnamesegment casts sizet vlen to uint8t when storing the Common Name CN length. An attacker who crafts a certificate with CN = victim's CN +...

Quantum-Safe Code Auditing: LLM-Assisted Static Analysis and Quantum-Aware Risk Scoring for Post-Quantum Cryptography Migration

The impending arrival of cryptographically relevant quantum computers CRQCs threatens the security foundations of modern software: Shor's algorithm breaks RSA, ECDSA, ECDH, and Diffie-Hellman, while Grover's algorithm reduces the effective security of symmetric and hash-based schemes. Despite NIS...

Amazon Linux 2023 : openssl, openssl-devel, openssl-fips-provider-latest (ALAS2023-2026-1522)

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1522 advisory. Issue summary: An OpenSSL TLS 1.3 server may fail to negotiate the expected preferred key exchange group when its key exchange group configuration includes the default by using the 'DEFAULT' keyword...

Empowering Mobile Networks Security Resilience by Using Post-Quantum Cryptography

The transition to a cloud-native 5G Service-Based Architecture SBA improves scalability but exposes control-plane signaling to emerging quantum threats, including Harvest-Now, Decrypt-Later HNDL attacks. While NIST has standardized post-quantum cryptography PQC, practical, deployable integration ...

Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities: Resource Estimates and Mitigations

This whitepaper seeks to elucidate implications that the capabilities of developing quantum architectures have on blockchain vulnerabilities and mitigation strategies. First, we provide new resource estimates for breaking the 256-bit Elliptic Curve Discrete Logarithm Problem, the core of modern...

Google Sets 2029 Deadline as Quantum Computers Threaten Encryption

Google fast-tracks post-quantum cryptography with a 2029 deadline as researchers warn quantum computers could break current encryption sooner than expected...

CVE-2026-3503

Protection mechanism failure in wolfCrypt post-quantum implementations ML-KEM and ML-DSA in wolfSSL on ARM Cortex-M microcontrollers allows a physical attacker to compromise key material and/or cryptographic outcomes via induced transient faults that corrupt or redirect seed/pointer values during...

ThreatsDay Bulletin: PQC Push, AI Vuln Hunting, Pirated Traps, Phishing Kits & 20 More Stories

Some weeks in security feel loud. This one feels sneaky. Less big dramatic fireworks, more of that slow creeping sense that too many people are getting way too comfortable abusing things they probably shouldn’t even be touching. There’s a little bit of everything in this one, too. Weird delivery...
