Optimized CSIDH Implementation Using a 2-torsion Point.

2020 · IACR Cryptology ePrint Archive

The implementation of isogeny-based cryptography mainly use Montgomery curves, as they offer fast elliptic curve arithmetic and isogeny computation. However, although Montgomery curves have efficient 3- and 4-isogeny formula, it becomes inefficient when recovering the …

Single-Trace Attack Using One-Shot Learning With Siamese Network in Non-Profiled Setting

2022 · IEEE Access

Recently, many studies have shown that using deep learning for side-channel attacks offers several advantages, including simplification of the attack phase and target breaking, even in protected implementations, while presenting outstanding attack performance. Power and …
