Abstract

LA INFORMACION SECRETA SE ALMACENA EN EL TRASMISOR Y EL RECEPTOR DE UN SISTEMA DE INTRODUCCION DE SIN TECLAS. LA INFORMACION INCLUYE UN CODIGO DE AUTORIZACION DE RESINCRONIZACION. CUANDO SE DEMANDA LA RESINCRONIZACION MEDIANTE LA PULSACION DEL BOTON DE LA TECLA APROPIADA, SE GENERA UN NUMERO ALEATORIO EN EL TRASMISOR Y SE ENVIA HASTA EL RECEPTOR JUNTO CON EL CODIGO DE AUTORIZACION DE RESINCRONIZACION. EL RECEPTOR COMPRUEBA EL CODIGO DE AUTORIZACION RECIBIDO CON SU CODIGO ALMACENADO. SI LOS CODIGOS COINCIDEN, EL RECEPTOR SUSTITUYE EL NUMERO ALEATORIO RECIBIDO DESDE EL TRASMISOR POR SU CODIGO DE ACCESO ALMACENADO EXISTENTE, COLOCANDO DE ESTA FORMA EL TRASMISOR Y EL RECEPTOR DE NUEVO EN SINCRONIZACION.
