Abstract

A content provisioner controls access to digital content by receiving a digital content request comprising a request for digital content, creating an authenticated digital content request if a user associated with the digital content request is authorized to access the digital content, determining one or more delivery parameters identifying a target device to receive the digital content, and sending the authenticated digital content request including the one or more delivery parameters. A content repository validates the authenticated digital content request, determines a session key if the authenticated digital content request is valid, encrypts the digital content using the session key, and sends the encrypted digital content. Determining a session key includes determining a target key based at least in part on a target ID, and applying a cryptographic process to a first key based at least in part on the authenticated digital content request, together with the target key.
