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...

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...

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...

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...

Google Develops Merkle Tree Certificates to Enable Quantum-Resistant HTTPS in Chrome

Google has announced a new program in its Chrome browser to ensure that HTTPS certificates are secure against the future risk posed by quantum computers. "To ensure the scalability and efficiency of the ecosystem, Chrome has no immediate plan to add traditional X.509 certificates containing...

Expert Recommends: Prepare for PQC Right Now

Introduction: Steal It Today, Break It in a Decade Digital evolution is unstoppable, and though the pace may vary, things tend to fall into place sooner rather than later. That, of course, applies to adversaries as well. The rise of ransomware and cyber extortion generated funding for a complex a...

Implementation and Transition to Post-Quantum Cryptography of the Minimal IKE Protocol

This paper concerns the Minimal Internet Key Exchange IKE protocol, which has received little attention to date, despite its potential to make the best-known IKE protocol sufficiently lightweight to be also applied in contexts where it is currently prohibitive, due to its large footprint. First, ...

Name of the Vulnerable Software and Affected Versions Chrome versions prior to the fix commit 8fe0b08e9a0e7e2d08b268f451f2c79962e6acd0 Description An incorrect removal of padding extension in utls for the non-pq variant of the HelloChrome 120 fingerprint. Chrome only removed this extension when...

When Security Meets Usability: An Empirical Investigation of Post-Quantum Cryptography APIs

Advances in quantum computing increasingly threaten the security and privacy of data protected by current cryptosystems, particularly those relying on public-key cryptography. In response, the international cybersecurity community has prioritized the implementation of Post-Quantum Cryptography PQ...

Practical Quantum Tokens: Challenges and Perspectives

The concept of quantum tokens dates back alongside quantum cryptography to Stephen Wiesner's seminal work in 19831. Already this initial work proposes society-relevant applications such as secure quantum banknotes, which can be exchanged between a bank and a customer. This quantum currency is bas...

Spinel: A Post-Quantum Signature Scheme Based on SLn(Fp) Hashing

The advent of quantum computation compels the cryptographic community to design digital signature schemes whose security extends beyond the classical hardness assumptions. In this work, we introduce Spinel, a post-quantum digital signature scheme that combines the proven security of SPHINCS+ CCS...

Post-Quantum Identity-Based TLS for 5G Service-Based Architecture and Cloud-Native Infrastructure

Cloud-native application platforms and latency-sensitive systems such as 5G Core networks rely heavily on certificate-based Public Key Infrastructure PKI and mutual TLS to secure service-to-service communication. While effective, this model introduces significant operational and performance...

Steganographic Information Hiding Via Symmetric Numerical Semigroups

We introduce a steganographic information hiding scheme based on structural properties of numerical semigroups arising from the Frobenius coin problem. Instead of encoding data through representable integers, the proposed protocol embeds information into the gap structure of carefully chosen...
