Abstract
Circuito de criptografía protegido por enmascaramiento, incluyendo dicho circuito unos medios para cifrar unas palabras binarias con la ayuda de al menos una clave kr c, unos medios para aplicar unos tratamientos (216) lineales y unos tratamientos (226) no lineales a dichas palabras, unos medios para enmascarar dichas palabras, donde las palabras binarias son desenmascaradas (214) aguas arriba de los tratamientos no lineales utilizando una máscara kr i y son enmascaradas (215) aguas abajo de los tratamientos no lineales utilizando una máscara kr+1 i, estando dicho circuito caracterizado porque las máscaras kr i y kr+1 i forman parte de un conjunto de máscaras propias para cada instancia del circuito, siendo las máscaras kr i unas máscaras secundarias deducidas de máscaras ki primarias, tales que kr+1 i >= P(kr i) y k0 i >= ki, correspondiendo la función P(x) a una función de permutación de los elementos de x.
