CCN-based virtual private community for extended home media service

As the majority of Internet traffic is becoming a variety of high quality multimedia and is mostly generated by consumers, efficient and usable content sharing in home as well as in mobile environment remains an elusive goal. For intuitive content sharing experience, an attractive approach named a content-centric networking (CCN) based virtual private community service has been proposed. The proposed CCN-based private community service had a hierarchical domain structure to efficiently manage multiple user and home domains. But it wasn´t described how users can construct the hierarchical domain. In this paper, we propose the procedure of how users intuitively and securely construct CCN-based virtual private community. To support the construction of the proposed CCN-based virtual private community, this paper proposes two main points: one is a membership association to represent the relationship between the members of a domain as well as between hierarchical domains. The other is location-limited channel (LLC)-based enrollment schemes to identify devices adaptively available for both short and long distance as well as to issue a membership credential to newcomer-devices. From the proposal, users can easily and securely identify community member´s devices without using a trust third party (TTP) and can configure the memberships of all community domain classes for a newcomer-device only by one registration operation. Hence, the users can securely and easily construct their private communities to share private contents among the members of the communities.
