Ensuring trust and confidentiality for adaptive video streaming in ICN

With the dissemination of huge amount of video content over the internet, information centric networking (ICN) has emerged as a potential candidate to effectively exploit it and improve the QoS. ICN decouples content from its location by caching, which can later be retrieved by consumers from their nearest locations. Various experimental studies have depicted the performance merits of dynamic adaptive streaming via HTTP (DASH) over ICN for improving QoS. However, there are two challenges that need to be addressed in the context of DASH over an ICN environment. The first one from content consumer domain is that the relevance, integrity, and provenance (RIP) of content should be guaranteed. RIP ensures trust establishment between publisher and consumer of content. The second one that concerns the content publisher is the confidentiality of DASH media, so that any consumer can view the particular quality or resolution of video based on his designated privileged rights. We address these two mentioned issues with the context of DASH over ICN. The performance and security analysis of our scheme depict its effectiveness for enforcing access control of adaptive streaming media in an ICN environment.
