Description
Summary:Content Centric Network (CCN) is one of the promising architectures for the future Internet that shifts the communication paradigm from the IP-based end-to-end to the content-centric. CCN enables users to obtain contents what they want regardless of where the contents are stored, and the contents are cached into network routers for future requests. Existing privacy-preserving approaches, like Onion routing in IP network, protect the privacy of the sender and recipient of a message as well as provide protection of contents during the traversal of a network. It is natural to prevent the intermediate routers or other nodes interpreting the contents if the contents are private such as Internet banking and shopping. But if contents are public such as YouTube video and New York Times articles, Onion routing loses chance of content caching and utilization, which is one of the main advantages of CCN. In this paper, we propose a new privacy-preserving protocol in CCN, which enables Interest aggregation and content caching which are CCN's main advantages. The experimental result shows that the proposed protocol is still able to use caching effect of CCN while providing user privacy.
