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.
