Privacy protected content sharing in extended home environment over Content-Centric Networking

Today, consumers possess a huge amount of personal contents due to increasing mobile devices and home appliances. This leads to extension of content sharing domain and thus, privacy protection of consumers becomes more important. In this paper, we propose a privacy protection mechanism providing the fine-grained access control on contents in the extended home environment. Our access control scheme is based on content encryption and supports a notion of groups and flexible access policy definition in content hierarchy using Access Control List (ACL). Though our proposed scheme is built on the hierarchical named content following CCN naming, it is also applicable to general hierarchies of named content or file systems as well.
