Construction of Generalized Weighing-Hadamard Matrices over Finite Fields
Gustavo T. Bastos, Miguel Beltrá, Sara D. Cardell +1
The paper studies Generalized Weighing-Hadamard matrices over finite fields, proving that invertible ones form a group, introducing an equivalence via orthogonal transformations, a…
Binomial sequences over prime fields
Miguel Beltrá, Sara D. Cardell, Verónica Requena
The binary binomial sequences correspond to the diagonals of the Pascal's triangle modulo 2. They have interesting properties such as they form a basis of the linear space of all b…
A New Representation of Binary Sequences by means of Boolean Functions
S. D. Cardell, A. Fúster-Sabater, V. Requena +1
Boolean functions and binary sequences are main tools used in cryptography. In this work, we introduce a new bijection between the set of Boolean functions and the set of binary se…
Cellular Automata as Generators of Interleaving Sequences
Sara D. Cardell
An interleaving sequence is obtained by combining or intertwining elements from two or more sequences. On the other hand, cellular automata are known to be generators for keystream…
