Most prior work on the use of key management algorithms to enable confidentiality of video delivery has been conducted in the context of IP Multicast. In this paper, we consider the unique challenges and opportunities of integrating key management algorithms in an overlay multicast system. We conduct a systematic and extensive performance evaluation of strategies for key dissemination in the context...
In this paper, we present an extensive study of key dissemination schemes in an overlay multicast context, and the first to involve actual implementation, real traces, and performance in Internet environments. Given that rekey traffic has stronger resilience requirements and is burstier than data traffic, we consider whether data and keys must be distributed using the same overlay or using two separate...
