On some methods for constructing almost optimal S-Boxes and their resilience against side-channel attacks

Reynier Antonio de la Cruz Jiménez

Abstract: Substitution Boxes (S-Boxes) are crucial components in the design of many symmetric ciphers. The security of these ciphers against linear, differential, algebraic cryptanalyses and side-channel attacks is then strongly dependent on the choice of the S-Boxes. To construct S-Boxes having good resistive properties both towards classical cryptanalysis as well side-channel attacks is not a trivial task. In this article we propose new methods for generating S-Boxes with strong cryptographic properties and therefore study the resilience of such S-Boxes against side-channel attacks in terms of its theoretical metrics and masking possibility.

Category / Keywords: secret-key cryptography / S-Box, permutations, hamming weight, nonlinearity, differ ential uniformity, graph algebraic immunity, differential power analysis, transparency order, confusion coefficient, signal-to-noise ratio.
