Abstract

La presente se relaciona con un sistema para una protección de copia mejorada comprendiendo un portador de grabación tal como un CD-RW+ o un DVD que almacenan información protegida de copia y un dispositivo para leer desde y / o escribir en el portador de grabación. Para ello, el portador de grabación (1) posee una primera área (3) que almacena informanción (datos), que es al menos parcialmente almacenada en forma encriptada (EAK(data)) esta parte siendo llamada un valor (EAK(data)), y que incluye una primera parte de información de desencriptado (HCK, EDNK(HCK), y el portador de grabación (1) también posee una segunda área (4) almacenando una segunda parte de la información de desencriptado (UCID), en donde ambos las primera (HCK) y segunda (UCID) parte de información de desencriptado sirven en el desencriptado de un valor (EAK(data)). Tal distribución de información de desencriptado en al menos dos áreas del portador de grabación puede también ser combinada con mecanismo de seguridad adicionales como por ejemplo, canales ocultos, claves de encriptado, mecanismos de conteo y listas de revocación.
