The paper presents a comprehensive analysis of the S-boxes used in the finalist candidates of the NIST Lightweight Cryptography (LWC) standardization process. It covers the following key aspects:
Overview of the finalist candidates that use S-boxes as a design component, including ASCON, ISAP, GIFT-COFB, Photon-Beetle, Elephant, and Romulus.
Introduction to the fundamental cryptographic properties of S-boxes, their classification based on relevance to different cryptanalysis techniques, and the theoretical bounds on these properties.
Detailed analysis of the S-boxes used in the finalist candidates, evaluating them against the established cryptographic properties and assessing their resistance to various attacks, including linear, differential, boomerang, and differential-linear cryptanalysis, as well as algebraic and side-channel attacks.
The analysis explores how the S-box properties influence the overall security of the cryptographic primitives and their compliance with NIST's security requirements for lightweight cryptography.
The study provides a comprehensive understanding of the S-box security profiles of the NIST LWC finalist candidates, enabling a deeper insight into their design choices and security strengths.
