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...

CVE-2026-24785

Clatter is a nostd compatible, pure Rust implementation of the Noise protocol framework with post-quantum support. Versiosn prior to2.2.0 have a protocol compliance vulnerability. The library allowed post-quantum handshake patterns that violated the PSK validity rule Noise Protocol Framework...

Clatter has a PSK Validity Rule Violation issue

Impact Protocol compliance vulnerability. The library allowed post-quantum handshake patterns that violated the PSK validity rule Noise Protocol Framework Section 9.3. This could allow PSK-derived keys to be used for encryption without proper randomization by self-chosen ephemeral randomness,...
