CVE-2026-2673

OpenSSL CVE-2026-2673 affects OpenSSL 3.5 and 3.6 series. The issue arises when an OpenSSL TLS 1.3 server uses the DEFAULT keyword to interpolate a built-in/default group list into its own configuration, causing the group tuples to lose their structure. As a result, the server may treat all suppo...

Layered Performance Analysis of TLS 1.3 Handshakes: Classical, Hybrid, and Pure Post-Quantum Key Exchange

In this paper, we present a laboratory study focused on the impact of post-quantum cryptography PQC algorithms on multiple layers of stateful HTTP over TLS transactions: the TCP handshake, the intermediate TCP-TLS layer, the TLS handshake, the intermediate TLS layer, and the HTTP application laye...

Post-Quantum Federated Learning: Secure and Scalable Threat Intelligence for Collaborative Cyber Defense

Collaborative threat intelligence via federated learning FL faces critical risks from quantum computing, which can compromise classical encryption methods. This study proposes a quantum-secure FL framework using post-quantum cryptography PQC to protect cross-organizational data sharing. We expose...

Securing Cryptography in the Age of Quantum Computing and AI: Threats, Implementations, and Strategic Response

This review examines how quantum computing and artificial intelligence challenge current cryptographic systems. We analyze the literature to assess the resilience of algorithms against quantum attacks Shor's and Grover's algorithms and AI-enhanced cryptanalysis. RSA and elliptic curve cryptograph...

PQC-LEO: An Evaluation Framework for Post-Quantum Cryptographic Algorithms

Advances in quantum computing threaten digital communication security by undermining the foundations of current public-key cryptography through Shor's quantum algorithm. This has driven the development of Post-Quantum Cryptography PQC, a new set of algorithms resistant to quantum attacks. While...

Preparing for the Quantum Era: Post-Quantum Cryptography Webinar for Security Leaders

Most organizations assume encrypted data is safe. But many attackers are already preparing for a future where today’s encryption can be broken. Instead of trying to decrypt information now, they are collecting encrypted data and storing it so it can be decrypted later using quantum computers. Thi...
