Open secure infrastructure to control user access to multimedia content

This work would start by describing OpenSDRM an open-source framework developed for the IST project MOSES., OpenSDRM is used to control the multimedia content consumption in conjunction with the new IPMPX MPEG-4 proposed standard. This architecture, composed by several building blocks, protects the content flow from creation to final user consumption on a specific device. This work devotes a special attention to the security aspects of the OpenSDRM processes and functions, describing its communication protocols and message exchanges as well as it introduces the security details about the user's digital wallet.
