Content security scheme for content centric networks

Abstract

Content Centric Networking (CCN) is a recently proposed internet paradigm that is based on content abstraction rather than host abstraction. People nowadays are interested in content and it does not matter from which locations they get the required content. Content requesting node has to make sure while receiving content from content publisher that whether the publisher and its content is trustable or not. To validate the authenticity of content on each node, an effective security scheme should be developed. In this paper we propose a content security scheme for CCN. We analyzed the performance of proposed scheme using ccnSim simulator and its security validation using AVISPA tool.
