Abstract

PROCEDIMIENTO DE TRANSMISION DE DATOS MEDIANTE AUTENTIFICACION EN UNA ESTRUCTURA DE AVISO DE PELIGRO DE UNA INSTALACION ANTIRROBO, EN QUE EN UNA ESTACION PRINCIPAL ESTAN ENCERRADAS VARIAS ESTACIONES INFERIORES Y SE TRANSMITEN DATOS ENTRE ELLAS. CADA ESTACION MUESTRA UN CRIPTOGRADO, AL MENOS UNA LLAVE SECRETA ALMACENADA Y UN CONTADOR BINARIO. LOS DATOS A ASEGURAR SE UNEN LOGICAMENTE CON LOS DATOS DEL CONTADOR Y SEGUIDAMENTE SE ENCIERRAN EN EL CRIPTOGRADO, CON LO QUE LOS DATOS AUTENTIFICADOS MUESTRAN UN TEXTO CLARO Y UN AUTENTIFICADOR UNIDO. EN CADA ESTACION SE COMPRUEBAN LOS DATOS AUTENTIFICADOS A SU RECEPCION Y VUELVEN A ELABORARSE EN AUTENTIFICACION CONCORDANTE. A DISTANCIAS REGULARES SE REQUIEREN LAS ESTACIONES INFERIORES DESDE LA ESTACION PRINCIPAL PARA TRANSMISION O RECONOCIMIENTOS, CON LO QUE SE OBSERVA LA RETROALIMENTACION.
