Abstract

Se presenta un dispositivo de cálculo electrónico (100) para efectuar aritmética ofuscada en un anillo conmutativo (Zn; Zn [x] /f (x)). El dispositivo de cálculo comprende un almacenamiento (110) dispuesto para almacenar una tabla de incremento (T) definida para un elemento de anillo de incremento (I; ut), la tabla de incremento mapea un elemento de anillo de entrada (k = uk1 - uk2) a una lista de números enteros de salida (T(K1, k2)) = (l1, l2)) que codifica un elemento de anillo de salida (I = u11 - u12), de tal manera que el elemento de anillo de salida es igual al anillo del elemento de anillo de incremento añadido al elemento de anillo de entrada (I = k + 1). Usando la tabla de incremento, una unidad de adición de anillo (130) añade una primera lista de números enteros de entrada de adición ((a1, a2)) que codifica un primer elemento de anillo de entrada de adición y una segunda lista de números enteros de entrada de adición (b1, b2)) que codifica un segundo elemento de anillo de entrada de adición. El dispositivo puede comprender una unidad de multiplicación de anillo (140) que también usa la tabla de incremento.
