Abstract

EL INVENTO TIENE POR OBJETO UN PROCEDIMIENTO PARA CERTIFICAR LA AUTENTICIDAD DE UN DATO INTERCAMBIADO ENTRE DOS DISPOSITIVOS CONECTADOS LOCALMENTE O A DISTANCIA MEDIANTE UNA LINEA DE TRANSMISION. EL DISPOSITIVO EMISOR (2) ELABORA UN MENSAJE CIFRADO (M) A PARTIR DE UN PARAMETRO (X), EN EL QUE AL MENOS UNO (X1) DE SUS CAMPOS DEBE SATISFACER UNA CONDICION DETERMINADA Y OTRO CAMPO (X3) CORRESPONDE AL DATO (D) A TRANSMITIR. EL DISPOSITIVO RECEPTOR (1) DESCIFRA EL MENSAJE (M) PARA ENCONTRAR UN PARAMETRO (X'') CUYO CAMPO (X''1) DEBE SATISFACER LA MISMA CONDICION QUE EL CAMPO (X1) PARA QUE EL CAMPO (X''3) CORRESPONDA AL DATO (D) EMITIDO. EL INVENTO SE APLICA ESPECIALMENTE EN TARJETAS DE CREDITO.
