END TO END SECURITY AND EFFICIENT VIDEO DELIVERY IN ENCRYPTED NETWORK CACHING
Journal Title: Elysium Journal of Engineering Research and Management - Year 2016, Vol 4, Issue 6
Abstract
To scale the delivery of massive volumes of videos, various new network architectures with optimizations for content-intensive applications have been proposed, such as information-centric networking (ICN) and others as surveyed. Among these proposals, one natural trend is to leverage in-network caching, i.e., storing the content in advanced network devices like cache-enabled routers. This paper proposed a novel networked system for efficient encrypted video delivery while preserving the benefits of in-network caching. As video chunks are encrypted before distribution, we first design a compact, efficient, yet encrypted video fingerprint index to empower the network with a fully controlled capability of locating the cached encrypted chunks for given encrypted requests. We then explain how to deploy the encrypted design in our proposed architecture, and present a secure redundancy elimination protocol to enable fast video delivery via leveraging cached encrypted chunks. Meanwhile, the proposed encrypted index and the secure RE protocol can flexibly work for encrypted data with different size granularity.
