Abstract

Tecnologia para suprimir el volumen de datos de una TRL (lista de revocacion de terminal), que es informacion que especifica las terminales que se van a invalidar, en un sistema estructurado a partir de una pluralidad de terminales, un dispositivo de distribucion para adquirir la TRL y distribuir datos solo a aquellas terminales que no se van a invalidar, y un dispositivo de gestion para generar la TRL. Este objeto se realiza por un sistema estructurado de un dispositivo de gestion, un dispositivo de distribucion de clave de contenido y una pluralidad de terminales. El dispositivo de gestion genera y transmite una TRL formada de datos que expresan los ID de terminales de todas las terminales que se van a invalidar (es decir, terminales cuyos ID tiene una cadena comun de bits), por solo un valor y una posicion de la cadena comun de bits en los ID, al dispositivo de distribucion de clave de contenido. Cada terminal retiene un ID de terminal que incluye un ID de fabricante, un numero de serie y similar, y pide la distribucion de una clave de contenido al enviar el ID de terminal al dispositivo de distribucion de clave de contenido. El dispositivo de distribucion de clave de contenido hace referencia a la TRL, juzga si el ID de terminal transmitido desde la terminal es aquel de una terminal invalidada, y si es negativo, encripte y transmite la clave de contenido a la terminal.
