An Affine Equivalence Algorithm for S-boxes based on Matrix Invariants
Xincheng Hu, Xiao Zeng, Zhaoqiang Liu +1
We investigate the affine equivalence (AE) problem of S-boxes. Given two S-boxes denoted as and , we aim to seek two invertible AE transformations such that $S_1\c…

Untrained Filtering with Trained Focusing for Superior Quantum Architecture Search
Lian-Hui Yu, Xiao-Yu Li, Geng Chen +3
Quantum architecture search (QAS) represents a fundamental challenge in quantum machine learning. Unlike previous methods that treat it as a static search process, from a perspecti…
