A Strategy for Preserving Privacy in the CCN
Yeongkwun Kim, Injoo J. Kim, Charlie Y. Shim · 2018
Content-centric networking (CCN) is one of many promising future Internet architectures adopted by the Named Data Networking (NDN) project to accommodate the needs of modern systems and applications. It enhances network efficiency by allowing network nodes to store obtained content (or data) in their caches for future requests. If the same content is later requested by different users, it can be delivered directly without contacting the original source of the content. However, this benefit may lead to privacy threats since not only is the content information itself vulnerable to potential breaches, but just as well any information concerning both the sender and the recipient. Thus, in this paper, we propose a strategy to preserve privacy of both the sender and recipient while maintaining such benefits of CCN as temporally storing transmitted content and Interest aggregation.
