Algorithms for Exponentiation in Finite Fields

Journal of Symbolic Computation, 2000
Let \(q\) be a prime power, and let \(r=nk+1\) be a prime not dividing \(q\). Let \(e\) be the index of the subgroup generated by \(q\) in the multiplicative group \(\mathbb Z ^*_r=\mathbb Z _r \setminus \{0\}\), and let \(K\) be the unique subgroup of order \(k\) in \(\mathbb Z ^*_r\). Let \(\beta\) be a primitive \(r\)th root of unity in GF\((q^{nk})\

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

A Register-Minimal ECC Accelerator Based on Hamburg’s Montgomery Ladder

IEEE Access
Point multiplication (PntMlt) is a fundamental operation in elliptic curve cryptography (ECC), and uniform PntMlt algorithms such as the Montgomery ladder (ML) are widely adopted to resist side-channel leakage. In particular, for short Weierstrass curves,

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

Advanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an
