Maximal cyclic subgroups of the groups of units of Galois rings: a computational approach
(Computational & Applied Mathematics, 2017-09-01) [Artigo]
We present a computational approach based on algorithmic techniques to obtain maximal cyclic subgroups of the groups of units in Galois rings. The objective of this work was to provide an automated methodology to obtain ...
Design of new 4 x 4S-box from finite commutative chain rings
(Computational & Applied Mathematics, 2017-06-01) [Artigo]
Substitution boxes (S-boxes) are the fundamental mechanisms in symmetric key cryptosystems. These S-boxes guarantee that the cryptosystem is cryptographically secure and make them nonlinear. The S-boxes used in conventional ...
