Abstract
Método para la delegación de datos estadísticos de forma segura. Un método para la delegación de datos estadísticos de forma segura, en el intercambio de información entre una entidad poseedora de los datos y una entidad procesadora de los mismos, el cual está basado en un homomorfismo de privacidad que permite una aritmética completa de tal modo que hace corresponder a las operaciones aritméticas (suma, resta, multiplicación y división) sobre datos no cifrados, una serie de operaciones análogas sobre datos cifrados para la obtención de un resultado, de modo que la entidad procesadora puede operar con los datos encriptados para obtener un determinado resultado al que se le permite acceder.
