AAA Mechanism for Mobile Router in Network Mobility Environment

Abstract: Network mobility and host mobility are the two different mobility deployments in mobile networks. Network Mobility Basic Support (NEMO BS) protocol provides session continuity while the whole network changes its point of attachment. While there are many advantages which show the NEMO as a dominant deployment of the future, still few security issues retard the commercial deployment. Many researchers contributed several mechanisms and techniques to protect the communications in NEMO environment. Authentication, Authorization and Accounting (AAA) is a part of security and the entry level shield. NEMO lacks in providing robust AAA mechanisms. As it grows and receives plenty of new users every day, new security issues are raising. Here, a new AAA mechanism is proposed for Mobile Router (MR). When the MR moves into another network, before consuming services, it must be authenticated and authorized. The proposed AAA mechanism provides a better authentication procedure by considering the time and the capacity of the mobile devices for computing the security protocols.
