Content Centric Network-based Virtual Private Community

While the majority of Internet traffic is becoming of high quality multimedia variety, also mostly generated by consumers themselves, efficient content sharing with intuitive useability and security measure in a mobile environment remains an elusive goal. In this paper, we present a Content-Centric Networking (CCN) based Virtual Private Community (VPC) service which aims at supporting intuitive content sharing experience in a secure and distributed manner. VPC is a hierarchical and closed user group which consumers themselves can easily create and manage on their own devices. In VPC architecture, consumer content is shared by VPC-based content forwarding policy which is also based on hierarchical content naming. We prototyped the VPC architecture on the consumer devices to demonstrate the potential of user-oriented and distributed consumer network platform.
