Personal networks federation in mobile DTV

Mobile and online DTV encourages new scenarios and applications to dynamically share content or delegate services between user's personal devices and networks. This requires the establishment of federations in a dynamic way, emerging the trust management as an important facet for that. Such trust management should be autonomous, user-centric, and dynamic to cope with forthcoming applications. This article addresses the mentioned requirements, by defining a SAML-compliant enhanced client to support federated environments for cooperation in mobile DTV scenarios. Such client is extended with a trust layer inside consumer electronic devices' software.
