Enhanced Security in Quantum Token Protocols Using Hybrid Spin-Photon Interfaces

Quantum token protocols enable unforgeable quantum tokens promising unconditional security beyond classical cryptographic assumptions. We show here that the three stages of the Quantum token protocols involving the preparation, storage and verification can be made more secure when involving...

Energy-Time Attack on Detectors in Quantum Key Distribution

Quantum key distribution is unbreakable in theory but may be hacked via imperfections in its hardware implementations. While many imperfections have been mitigated by countermeasures and advanced security proofs, several remain unsolved. One of these is a superlinear behaviour in single-photon...

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...

Machine Learning Techniques for Enhancing Quantum Key Distribution

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...
