Transparency order versus confusion coefficient: a case study of NIST lightweight cryptography S-Boxes
2021
Cybersecurity
Preserved Fulltext
Taking the 4-bit and 8-bit S-Boxes used in NIST Lightweight Cryptography candidates as concrete examples, this paper takes a comprehensive study of the applicability of these metrics. ...
S-Boxes) of cryptographic algorithms will be chosen as primary targets of side-channel attacks (SCAs). ...
then explore the theoretical metric that fits the reality better. ...

In this work, we perform an extensive investigation and construct a portfolio of S-boxes suitable for secure lightweight implementations, which aligns well with the ongoing NIST Lightweight Cryptography ...
In particular, we target good functional properties on the one hand and efficient implementations in terms of AND depth and AND gate complexity on the other. ...
