Abstract
La invención propone una solución para identificar el origen de un módulo de seguridad en un sistema de televisión de paga, de acuerdo con los pasos de: - recibir por el sistema decodificador de televisión de paga un servicio que comprende por lo menos un primer flujo; un segundo flujo y un flujo de cifra de control; el primer flujo está encriptado por una primera cifra de control (CW1) y el segundo flujo está encriptado por un segundo flujo (CW2) - extraer del flujo de cifra de control, mensajes de autorización que contienen por lo menos una cifra de control principal (CW) que permite extraer las cifras de control primera y segunda y las condiciones de acceso; - transferir el flujo de cifra de control al módulo de seguridad; - extraer los mensajes de autorización del flujo de cifra de control y comprobar las condiciones de acceso; - si se satisfacen las condiciones de acceso, determinar las cifras de control primera y segunda de la cifra de control principal en el mensaje de autorización; - determinar un parámetro interno del módulo de seguridad; siendo este parámetro interno único por módulo de seguridad; - seleccionar una cifra de control actual de la primar o la segunda cifra de control, basada en parte del parámetro interno, que corresponde al flujo primero o segundo; - seleccionar un flujo actual del flujo primero o segundo, de acuerdo con la selección de la cifra de control primera o segunda;- desencriptar el flujo actual con la cifra de control actual. - trasmitir la cifra de control actual al decodificador de televisión de paga;.
