Considering the large amounts of data to be processed when distributing 3D audio-visual content, it is reasonable to combine broadcasting and P2P distribution, an approach that has been chosen within the EU project DIOMEDES. Two issues to be solved within such a scenario are related to security: Access control, to support business models where only authorized receivers can access certain content, and content authentication, to avoid distribution of unauthorized and corrupted content. This paper describes how access control and content authentication have been addressed within DIOMEDES, including evaluation of different broadcast encryption schemes with respect to the requirements of the hybrid DVB-T2/P2P distribution scenario. The presented approach is agnostic with respect to both the content format and the P2P network used, and can also be adapted to other, similar scenarios.
