CASTRO PEREZ, OSCAR; VILLARROEL VILLARROEL, FELICIA  and  BRITO QUIJADA, DANIEL. NO LINEALIDAD DISTINTA DE CERO EN FUNCIONES BOOLEANAS BALANCEADAS. Saber [online]. 2015, vol.27, n.4, pp.565-572. ISSN 2343-6468.

Not all boolean functions are appropriate for construct good boxes S (in the sense having good cryptographic properties including: high nonlinearity, balance, high algebraic degree, resistance, etc). The boolean functions n  eligible number, with n input bits, is  22  (Rodríguez 2007). Even for moderate values of n, the search space is  immense. Thus, in the present work, the bases that describe the ring Z are used itemize to achieve cryptographic concepts so that originating deterministic algorithmic methods to develop models that allow, efficiently, locate and discard some boolean functions with balance and nonzero nonlinearity.

Keywords : integers ring; binary chain; boxes S; cryptographic properties.
