Abstract

Un aparato de almacenamiento de información incluye una sección de almacenamiento configurada para almacenar contenido cifrado y una clave de cifrado que se aplicará al descifrado del contenido cifrado. La sección de almacenamiento almacena una clave de cifrado de conversión producida mediante la operación aritmética de la clave de cifrado con una firma electrónica que son datos de configuración de un conjunto de archivos de firma de contenido cifrado correspondiente al contenido cifrado. Además, la firma electrónica es para datos que incluyen datos de configuración del contenido cifrado y la clave de cifrado. El aparato de almacenamiento de información puede hacer que un aparato de reproducción, que lee el contenido cifrado desde la sección de almacenamiento, ejecute un proceso de descifrado para llevar a cabo la adquisición de clave de cifrado mediante la operación aritmética donde la firma electrónica se aplica a la clave de cifrado de conversión.
