On the representation of S-boxes in block ciphers
V. A. Vitkup Novosibirsk State University
Abstract:
A known method of S-boxes partition applied against side-channel attacks is considered. Nowadays, necessary partitions are found for all the affine equivalence classes except one. In the paper, it is proved that S-boxes of this class do not have admissible partition.
Keywords:
S-box, vectorial Boolean function, affine equivalence.
