Abstract

Se proporciona una unidad (225) segura de derechos criptograficos para regular criptograficamente el acceso a contenidos (215) digital que incluye un procesador (235) de control de interfaz y una unidad (260) criptografica especializada que protege el acceso a una memoria (265). La unidad criptografica produce claves de descifrado (267) mediante la utilizacion de claves de derechos almacenadas para transformar otros datos recibidos del procesador (235) control. Debido a que el procesador (235) control no tiene la capacidad para tener acceso directamente a la memoria (265) protegida, la seguridad puede permanecer efectiva incluso si se compromete al procesador con (235) control. Para evitar la ingenieria inversa de las transformaciones criptograficas, la invencion proporciona un generador de algoritmos que utiliza fuentes aleatorias para producir definiciones de algoritmo en una forma legible en la maquina. Debido a que el generador mismo no contiene ningun secreto, se puede enviar para revision abierta. Otras caracteristicas permiten al proveedor (200) de contenido realizar auditorias del acceso (296) al usuario (290) quien puede obtener el contenido (275) descifrado a traves de un dispositivo (280) de salida.
