Abstract

Un procedimiento para convertir un conjunto de datos cifrados en un cifrado de bits individuales que representan el conjunto de datos, comprendiendo el procedimiento las etapas de: generar un número aleatorio y calcular un cifrado basado en bits del número aleatorio; calcular de manera segura una suma cifrada en función del conjunto de datos cifrados y el número aleatorio cifrado; descifrar la suma cifrada y determinar una representación binaria de la suma; y crear el cifrado de dichos bits individuales que representan el conjunto de datos cifrados procesando la representación binaria de la suma con el número aleatorio cifrado.
