Desde un punto de vista matem\u00e1tico, la confiabilidad de los c\u00f3digos PIN de seis d\u00edgitos es significativamente mayor que la de los de cuatro. Pero los usuarios prefieren ciertas combinaciones de n\u00fameros, por lo que algunos PIN se utilizan con m\u00e1s frecuencia, casi borrando la diferencia en complejidad entre los c\u00f3digos de seis y cuatro d\u00edgitos.<\/p>\n<p>En el estudio, los participantes de los experimentos utilizaron dispositivos Apple o Android y establecieron c\u00f3digos PIN de cuatro o seis d\u00edgitos. En los dispositivos Apple, desde la versi\u00f3n iOS 9, se estableci\u00f3 una lista negra de combinaciones num\u00e9ricas prohibidas para los c\u00f3digos PIN, cuya selecci\u00f3n est\u00e1 autom\u00e1ticamente prohibida. Los investigadores tuvieron en mano ambas listas negras (para c\u00f3digos de seis y cuatro d\u00edgitos) y realizaron un ataque por fuerza bruta en sus computadoras. La lista negra recibida de Apple para PINs de cuatro d\u00edgitos conten\u00eda 274 n\u00fameros, mientras que la de seis d\u00edgitos conten\u00eda 2910.<\/p>\n<p>Para los dispositivos Apple, el usuario tiene 10 intentos para introducir el PIN. Seg\u00fan los investigadores, en este caso la lista negra pr\u00e1cticamente no tiene sentido. Con 10 intentos, es dif\u00edcil adivinar el n\u00famero correcto, incluso si es muy simple (como 123456). Para los dispositivos Android, en 11 horas se pueden realizar 100 intentos de ingreso de PIN, y en este caso la lista negra se convierte en un medio m\u00e1s confiable para evitar que el usuario ingrese una combinaci\u00f3n simple y prevenir el hackeo del smartphone a trav\u00e9s de la prueba de n\u00fameros.<\/p>\n<p><center><\/center><\/p>\n<p>En el experimento, 1220 participantes eleg\u00edan sus propios c\u00f3digos PIN, mientras que los experimentadores intentaban adivinarlo en 10, 30 o 100 intentos. La adivinanza de combinaciones se realiz\u00f3 de dos maneras. Si se activaba la lista negra, los tel\u00e9fonos inteligentes eran atacados sin usar n\u00fameros de esa lista. Sin la lista negra activada, la indagaci\u00f3n comenzaba con la combinaci\u00f3n de n\u00fameros de la lista negra (ya que eran los m\u00e1s utilizados). Durante el experimento, se determin\u00f3 que un c\u00f3digo PIN de 4 d\u00edgitos, elegido de manera razonable, es lo suficientemente seguro con un n\u00famero limitado de intentos y, de hecho, es un poco m\u00e1s confiable que uno de 6 d\u00edgitos.<\/p>\n<p>Los c\u00f3digos PIN de 4 d\u00edgitos m\u00e1s comunes resultaron ser las combinaciones 1234, 0000, 1111, 5555 y 2580 (esta es una columna vertical en el teclado num\u00e9rico). Un an\u00e1lisis m\u00e1s profundo mostr\u00f3 que la lista negra ideal para c\u00f3digos PIN de cuatro d\u00edgitos deber\u00eda contener alrededor de 1000 entradas y diferir ligeramente de la que fue generada para dispositivos Apple.<\/p>\n<p><img decoding=\"async\" alt=\"Investigaci\u00f3n: los c\u00f3digos PIN de seis d\u00edgitos no son m\u00e1s seguros que los de cuatro d\u00edgitos\" src=\"\/wp-content\/uploads\/2020\/03\/70343d92397681d1aba304233a1edb77.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/p>\n<p>Finalmente, los investigadores descubrieron que los c\u00f3digos PIN de 4 y 6 d\u00edgitos son menos seguros que las contrase\u00f1as, pero m\u00e1s confiables que el bloqueo gr\u00e1fico de tel\u00e9fonos inteligentes (basado en patrones).
