Abstract

Algunas modalidades se relacionan con un nodo de red electrónica (110) configurado para una operación criptográfica. El nodo de red obtiene una matriz compartida A al seleccionar enteros, polinomios y/o coeficientes de polinomios desde un bloque compartido, el bloque compartido se comparte con el segundo nodo de red, en donde la selección se hace de acuerdo con una o más funciones de selección.
