Abstract

Método para el funcionamiento de un sistema de acceso condicional para aplicaciones de emisión por ondas, cuyo sistema de acceso condicional comprende una serie de subscriptores, poseyendo cada subscriptor un terminal que comprende un módulo de acceso condicional y un dispositivo de seguridad para almacenar autorizaciones, indicando cada autorización un servicio que el subscriptor que recibe la autorización está autorizado a contemplar, de manera que se envían mensajes de gestión de autorización, EMM, a un dispositivo de seguridad o grupo de dispositivos de seguridad, proporcionando cada uno de dichos EMM una autorización y correspondiente fecha de caducidad, de manera que las autorizaciones son renovadas periódicamente, de acuerdo con sus fechas de caducidad, por envío de EMM que actualizan las fechas de caducidad, caracterizado porque se envía un conjunto de mensajes de gestión de autorización de ampliación (EMM de ampliación), como mínimo, a una parte de todos los dispositivos de seguridad, indicando cada uno de dichos mensajes de gestión de autorización de ampliación que todas las autorizaciones que tienen una fecha de caducidad dentro de un primer período predeterminado, son ampliadas con un segundo período predeterminado, de manera que las EMM de actualización de las fechas de caducidad son enviadas después de las EMM de ampliación.
