Abstract

Se proporciona un método y un aparato para la distribución segura de contenido digital. De conformidad con al menos una realización, un dispositivo intermediario mantiene una lista de pozos de contenido autorizados, la cual se usa para permitir la reautorización de un primer pozo de contenido para accesar al primer contenido de la primer fuente de contenido cuando el primer pozo de contenido tiene una entrada de primer pozo de contenido en la lista de pozos de contenido autorizados. De conformidad con al menos una realización, la reautorización está condicionada a sí el estado actual de la entrada del primer pozo de contenido no ha expirado aún. De conformidad con al menos una realización, el dispositivo intermediario permite la autenticación del primer pozo de contenido por la primera fuente de contenido cuando no existe la entrada del primer pozo de contenido en la lista de pozos de contenido autorizados o cuando el estado actual de la entrada del primer pozo de contenido ha expirado.
