SECURITY SCHEME IN INFORMATION-CENTRIC NETWORK (ICN)

Abstract

Due to the high demand for efficient content delivery by internet users, Information-Centric Network (ICN) tends to emerge as an alternative communication model for an internet architecture and communication network to enhance efficient content delivery. ICN is an emergence technology, proposed to replace the existing host-to-host communication network with an information-centric network architecture, which enables users to request content based on their names rather than their hosting location (IP address) as in the case of current internet architecture. ICN would cope with the increased demand for efficient contents delivery on the internet and also provide an alternative approach solution to many significant issues and challenges in the current IP-based Internet architecture such as mobility, content dissemination, and multi-path forwarding. ICN network has an in-build properties such as in-network caching, content-based security, forwarding plane (using PITs), and name-based routing and forwarding. These include properties make the ICN network vulnerable to several types of security attacks. The Current internet security model is protecting the communication channel between a client and a server through Transport Layer Security (TLS) scheme While in ICN, security model is based on name content object/name data object (NCO/NDO) known as (object-based security).
