Due to the huge demand for mobile applications and devices, many new technologies and mechanisms are being invented. NEtwork MObility (NEMO) is a kind of deployment scenario where an entire network moves from one location to another location. While changing the point of attachment, there is possibility for the hacker to interrupt communication and to claim it as a genuine node. Authentication, Authorization and Accounting (AAA) become inevitable in security. Authentication is the key solution to protect from many security attacks because it authenticates the nodes before accessing the network. The Visiting Mobile Node (VMN) is to be authenticated because it belongs to another Foreign Network (FN). The loyalty of the VMN must be ensured before providing access to the Mobile Network (MN).
