MiNTT: A Family of Module Lattice-Based Cryptographic Compression Functions

IEEE Access
A cryptographic compression function is the part of a hash function most responsible for compressing input while avoiding collisions. In recent years, NIST has released a Call for Proposals for a variety of cryptographic primitives, albeit there have ...

Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks

Advanced Quantum Technologies, Volume 9, Issue 8, August 2026.
Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?

AlquistCoder: A Synthetic Data Approach to Training Compact Secure Coding Assistants and Building Security Benchmarks

Computational Intelligence, Volume 42, Issue 4, August 2026.
ABSTRACT Large language models are increasingly used as programming assistants, but their security behavior remains uneven: they may generate code with vulnerable patterns, and they may provide actionable help for malicious requests. This paper introduces AlquistCoder, a compact 3.8B‐parameter coding assistant designed to address both risks through ...

Fully Quantum Hash Function

We introduce a novel, \textit{fully} quantum hash (FQH) function within the quantum walk on a cycle framework. We incorporate deterministic quantum computation with a single qubit to replace classical post-processing, thus increasing the inherent security. Further, our proposed hash function exhibits zero collision rate and high reliability. We further

SiOx‐Based Probabilistic Bits Enabling Invertible Logic Gate for Cryptographic Applications

Advanced Intelligent Systems, Volume 8, Issue 7, July 2026.
To enable lightweight hardware encryption and decryption, a Ti/SiOx/Ti threshold switching device is engineered to generate controllable stochastic oscillations. By tuning the input voltage, the device produces a programmable spike probability governed by intrinsic switching dynamics, enabling probabilistic bits that construct an invertible ...
