Abstract:
The different technologies deployment for information exchange on the network and the terminal diver-sity that support them, produce users unwittingly attracted to the Internet that is everywhere in their daily lives. Users require a high Quality of Service (QoS) especially for video streaming applications that generate the main part of the internet traffic. For service providers, it is important to reduce this traffic and increase the Quality of user Experience (QoE). To meet these needs, two additional keys must be exploited: routing and caching. Content Centric Networks (CCN), which is one of the most developed Information Centric Networks (ICN) approaches, offers efficient management of caches at CCN nodes, but the lack of scalable routing is one of the obstacles that slow down its deployment at the internet level. Then, Software Defined Networks (SDN) architecture has been proposed to facilitate programming of the network and to automate the management of the complex architecture but without taking advantage of the capacity of the intermediate caches of the connected nodes. To accomplish tasks, a CCN node uses three tables, Content Store, Forwarding Information Base, and Pending Interest Table, which present attacks to privacy of content requesters and producers. In this paper we propose a Secure In-network Caching Scheme (SICS) for CCN networks based on SDN architecture taking advantage of its global vision. SICS does not only improve cache hit rate and reduce response time, but it also allows to monitor access to CCN routers and detect attacks in order to block them. The results of our model implemented in NS-3 simulator will be presented and evaluated.
