A Privacy Preserving Strategy Based on Anonymous Group in Content Centric Network

Abstract

In Content Centric Networking (CCN), "publish-request-response" is presented in data communications between users and publishers, as well as the response message could be cacheable in the routing node. Based on this model, privacy disclosure is a threat to users and publishers. In this paper, a strategy for CNN privacy information protection is proposed. This system adopts hybrid encryption method which can take advantage of nodes ubiquitous cache in CCN. At the same time, it ensures fewer numbers of symmetric keys, which can minimize cache overhead. In addition, this paper puts forward the construction of anonymous group, which can hide the real signer and protect the identity of it.
