Abstract

Un método para autorizar acceso condicional a un producto de datos digitales cifrados, que incluye almacenar por lo menos un conjunto de acreditaciones en un dispositivo seguro, cada acreditación incluyendo un identificación de producto e información de expiración, recibir mensajes de control de acreditación desde un sistema decodificador que incluye un dispositivo para descifrar productos de datos digitales cifrados usando palabras de control, cada mensaje de control de acreditación incluyendo un identificador de producto, y en un primer modo, regresar por lo menos una palabra de control en respuesta a un mensaje de control de acreditación que incluye un identificador de producto si el identificador de producto corresponde a un identificador de producto en una acreditación almacenada que incluye información de expiración que indica que la acreditación es válida, y en un segundo modo, ajustar progresivamente un contador a un valor predeterminado y regresar por lo menos una palabra de control en respuesta también a los mensajes de control de acreditación que incluye un identificador de producto si el identificador de producto corresponde a un identificador de producto en una acreditación almacenada que incluye información de expiración que indica la expiración de la acreditación y si el contador está en un valor entre un valor inicial y el valor predeterminado; el contador se fija a un valor inicial para empezar la operación en el segundo modo al recibir un mensaje de control de acreditación que incluye un identificador de producto correspondiente a un identificador de producto en una acreditación almacenada que incluye información de expiración que indica la expiración de la acreditación.
