Named-Data security scheme for Named Data Networking

Abstract

Information Centric Networking (ICN) approach constitutes one of the promising results of Internet of the Future research activities. Content is the central element in this approach. Content Centric Networking (CCN) and Named Data Networking (NDN) are the most emerging ICN projects. They adopt a security model based on named data in which content is signed by the content producer. In this paper, we propose to enhance security in CCN/NDN projects. We first define requirements for their naming system in order to provide security services that bind both naming and content. Then, we propose a hybrid scheme which combines public-key infrastructure (PKI) and Hierarchical Identity-Based Cryptography (HIBC) in order to meet the defined requirements. This proposal represents a defense against a potential attack and perfectly fits in with the structures of the various objects of CCN/NDN.
