A Framework to Enhance Security in Nemo Environment Using AAA Mechanisms

Abstract

One of emerging trends in the mobile network era is Network Mobility (NEMO). It was standardized by the Internet Engineering Task Force (IETF) and gained attention of the researchers because of research opportunities that it provides. Though it was developed based on MIPv6, there are few spots that must be analyzed and rectified, especially in the security aspects. According to the literatures, NEMO lacks in providing a robust Authentication, Authorization and Accounting (AAA) services to its users. AAA operations must be performed for all the players of the mobile network, because a hacker may reside at any place and try to access the mobile network by hiding behind valid or genuine nodes’ addresses. This research work aims to provide an AAA framework for NEMO by comprising three different mechanisms which are developed for Local Mobile Node (LMN), Visiting Mobile Node (VMN) and Mobile Router (MR). Simulation and performance analysis are done.
