| Popis: | © 2019, Springer Science+Business Media, LLC, part of Springer Nature. In this paper we focus on S-box constructions. We consider the uniformity property of an S-box which plays an important role in Threshold Implementations (TI). Most papers so far have studied TI sharings for given S-boxes. We proceed in the opposite way: starting from n-bit S-boxes with known sharings we construct new (n + 1)-bit S-boxes from them with the desired sharings. In addition, we investigate the self-equivalency of S-boxes and show some interesting properties. ispartof: CRYPTOGRAPHY AND COMMUNICATIONS-DISCRETE-STRUCTURES BOOLEAN FUNCTIONS AND SEQUENCES vol:11 issue:3 pages:385-398 status: published |
