Abstract
La presente se refiere a una unidad de tratamiento de datos de audio/video numéricos y un método de control de acceso a dichos datos. La unidad de tratamiento (UT) de datos de audio/video numéricos encriptados con palabras de control (CW) proveniente de mensajes de control (ECM) comprende una unidad de desciframiento (DMX) de los datos de audio/video (DT), una unidad de descompresion (MPEG), una interfaz de entrada/salida de los datos de audio/video tratados y medios de comunicacion hacia un modulo de seguridad (SM). Las unidades de desciframiento (DMX) y de descompresion (MPEG) comprenden respectivamente una unidad de encriptacion (EC) y una unidad de desencriptacion (DC) disponiendo cada una de por lo menos una clave personal (Kec, Kdc) y de una clave de encriptacion comun (Ki). Está caracterizada por el hecho de que incluye los medios de transmision protegida de la clave comun (Ki) y de la palabra de control (CW) extraída de un mensaje de control (ECM) entre el modulo de seguridad (SM), la unidad de desciframiento (DMX) y la unidad de encriptacion (EC) utilizando la clave personal (Kec) de la unidad de encriptacion (EC). El desciframiento por la unidad de desciframiento (DMX) de los datos de audio/video (DT) con la palabra de control (CW) y el reencriptado por la unidad de encriptacion (EC) de dichos datos descifrados con la clave comun (Ki) solo en posibles tras una verificacion exitosa de la palabra de control (CW) y de la clave comun (Ki). Tras el almacenamiento temporal, los datos de audio/video (DT) reencriptados solo pueden ser desencriptados por la unidad de desencriptacion (DC) si la clave comun (Ki) ha sido verificada positivamente por el modulo de seguridad (SM) con ayuda de un numero aleatorio (AL) generado por la unidad de desencriptacion (DC).
