Securing the forwarding plane in information centric networks

Abstract

Information Centric Network is a brand new architecture that focuses on the information objects rather than the location of end users. It aims to replace the current end-to-end model with the publish-subscribe model to solve many issues including security, routing scalability, mobility. One of the main features in this network is the use of a simple and light multicast forwarding fabric, which is suitable for large-scale publish/subscribe. This routing system is very fast packet forwarding with small forwarding tables. It is also more energy efficient than the currently used ones. In this paper we enhance the security level of this mechanism and prevent malicious users from injecting traffic using brute force attacks, replay attacks and computational attacks. We propose and analyse two initial designs that mitigate these attacks.
