Beyond Affine Invariants: A Hamming-Weight Correlation Metric for Template-CPA Leakage in Key-Dependent S-boxes

Classical selection criteria for cryptographic S-boxes—nonlinearity $\mathrm{NL}$, differential uniformity $\delta$, boomerang uniformity $\beta_{\mathrm{B}}$, algebraic degree $\deg$—are invariants o

A Systematic Literature Review on Optimising CRYSTALS-Dilithium (ML-DSA) Performance for IoT Devices via Lightweight Hashing

Background: The migration to post-quantum cryptography confronts resource-constrained Internet of Things (IoT) devices with a material performance cost. CRYSTALS-Dilithium, standardised as the Module-

SHARMONY: Composing SHA-2 and SHA-3 Hardware for Crypto-Agile PQC

This work composes SHA-2 and SHA-3 into a unified hardware architecture, bringing them together as a single, efficient cryptographic ensemble. This need is driven in particular by Post-Quantum Cryptog

Note on Number-Theoretic Transforms for Implementers -- Butterflies, Twisting, Incompleteness, and Good's Trick

We develop the radix-2 number-theoretic transform (NTT) and its butterflies, the twisting trick and why it never changes the transform, the freedom to use Cooley--Tukey butterflies in both di

Toward a Secure Fixed-Point Implementation of the Falcon Signature Scheme

Falcon was selected by NIST in 2022 for standardization as a post-quantum digital signature scheme. Among all standardized signature schemes, Falcon achieves the smallest signature size. Its main draw

Hybrid hash function based on the DLP and SIS problems

This short note discusses in detail a folklore but little-known hybrid hash function grounded on both the discrete logarithm and short integer solution problems. In particular, specific satisfactory p

Optimizing Polynomial Multiplication and Fixed-Weight Sampling for HQC on ARM Cortex-M4

In this paper, we present an optimized implementation of Hamming Quasi-Cyclic (HQC) on the ARM Cortex-M4. We optimize (i) the polynomial multiplication and (ii) the support expansion in fixed-weight s
