Abstract
A method and apparatus for secure distribution of digital content is provided. In accordance with at least one embodiment, an intermediate device maintains an authorized content sink list which it uses to allow reauthorization of a first content sink for access to first content from a first content source when the first content sink has a first content sink entry on the authorized content sink list. In accordance with at least one embodiment, reauthorization is conditioned upon a first content sink entry currency status having not yet expired. In accordance with at least one embodiment, the intermediate device allows authentication of the first content sink by the first content source when no first content sink entry exists on the authorized content sink list or when the first content sink entry currency status has expired.
