Exact Stratification and Affine Mass Formulas for Split Richelot Data over Finite Fields
Hung T. Dang, Diep V. Nguyen
The Richelot -step is the standard step of explicit genus-2 isogeny computation. We determine the exact stratification of its input space over a finite field …

Architectural Limits of Cloud TPUs in Finite-Field Cryptography
Hung Dang, Xuan Phu Dang, Tue Nguyen
We empirically characterise the cost-efficiency deficit between cloud Tensor Processing Units and GPUs for finite-field cryptography. Against A100 GPU baselines (cuZK), we measure…
