openssl: OpenSSL TLS 1.3 server may choose unexpected key agreement group

A key group selection preference flaw has been discovered in OpenSSL. 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. A less preferred key exchange may be used...

Post-Quantum Cryptography Is Coming, but Your DNS Might Not Be Ready

Learn why crypto-agility depends not just on adopting the right standards, but on maintaining a clear, unified view of your DNS environment before the migration begins...

Certification of Network Quantum Sensing

The distribution of quantum sensors on quantum networks is a key enabler of quantum technologies in interferometry, gravimetry, timekeeping, biological monitoring, and beyond. Yet, guaranteeing the security of these distributed sensors over noisy, insecure networks remains a formidable challenge...

Hardware-Aware QAOA for Honeypot Traffic Partitioning on 100+ Qubit IBM Quantum Processors

Denial-of-service DoS and distributed denial-of-service DDoS mitigation requires separating malicious traffic from benign traffic while minimizing disruption to legitimate users. Prior work proposed mapping honeypot traffic partitioning to a weighted MaxCut problem and solving the resulting graph...

The Clock Is Already Ticking: Why Post-Quantum Cryptography Can’t Wait

There is a question I have been hearing more and more from CISOs, compliance officers, and security architects over the past year. It does not start with "we had a breach" or "we failed an audit." It starts with something that sounds almost philosophical: " Are we quantum-safe?" A year ago, that...

CVE-2026-41509

CROSS implementation contains reference and optimized implementations of the CROSS post-quantum signature algorithm. Prior to commit fc6b7e7, there is a buffer overflow in cryptosignopen caused by an underflow of the integer mlen. This issue has been patched via commit fc6b7e7...

CVE-2026-41039

This vulnerability exists in Quantum Networks router due to improper access control and insecure default configuration in the web-based management interface. An unauthenticated attacker could exploit this vulnerability by accessing exposed API endpoints on the targeted device. Successful...

CVE-2026-41038

This vulnerability exists in Quantum Networks router due to lack of enforcement of strong password policies in the web-based management interface. An attacker on the same network could exploit this vulnerability by performing password guessing or brute-force attacks against user accounts, leading...

CVE-2026-41036

This vulnerability exists in Quantum Networks router due to inadequate sanitization of user-supplied input in the management CLI interface.

CVE-2026-33583

Exposure of the QKEY used as input into the ‘OTA-Quantum’ device registration process and internal system keys via an unauthenticated and unencrypted HTTP GET method in the Arqit Symmetric Key Agreement Platform. This issue affects Symmetric Key Agreement Platform: before 26.03...

Empirical Evaluation of Large Language Models for Migration of Code Fragments to Post-Quantum Cryptography

The transition to post-quantum cryptography PQC requires not only replacing vulnerable cryptographic primitives, but also refactoring the surrounding software logic. While existing PQC migration frameworks provide organizational guidance, practical code-level remediation remains largely manual an...
