Abstract

Objective: Named Data Networking (NDN) is an emerging model to replace the existing IP networks which focuses mainly on Content or the data. The notion of the work is to provide solution to the Interest Flooding Attack (IFA) .Content access is also restricted and transferred only to the permitted user by using NDN specific Authentication, Authorization, and Accounting (AAA) server. Methods/Statistical Analysis: Major data transferred over the IP network is Contents. This gave way for a new Content Centric Network (CCN) design known as NDN. Not all the contents in the network should be accessible by all users. There are some confidential data which should be accessible only by the specific users. This Confidential Data Access Control model solves this issue by introducing few changes in the existing packet structures and by adding interest validation algorithm in Content Provider (CP) and at the NDN routers. This model also introduces NDN specific AAA Server which does authentication and authorization to check the access restriction to the requested content by the users. NDN AAA server is associated with all the CPs. Findings: The system when implemented showed better results with improved performance in overall network by avoiding Flooding attack and securing content packets. Application/ Improvement: Hence, the proposed model of NDN is designed to improve security and also to provide access restrictions for specified users to access the content. This is an implementation paper of the previously published algorithms.
