Towards named data networking technology: Emerging applications, use cases, and challenges for secure data communication

Abstract

Named Data Networking (NDN), an emerging Internet architecture is altering the basics of the networking model by making content directly addressable and routable. NDN changes the communication model by shifting from the current host-centric model to a content-centric model naming each content object hierarchically instead of using IP addresses. This change enables data consumers to request content using application-layer names that optimize network traffic and allow data security directly at the network layer, making the content of every data packet verifiable and enabling resilient communication in dynamic network environments, such as mobile ad hoc networks. This paper presents the concepts of NDN architecture and a comprehensive overview of emerging application use cases of the technology for secure data communications. We discuss the integration of NDN with the current Internet protocol and highlight how NDN works as a facilitator for addressing numerous concerns related to unique applications. Furthermore, we highlight the trust management and security aspects of NDN. Finally, we outline challenges relating to NDN adoption and present some proposed solutions.
