Host Identity Protocol and Proxy Mobile IPv6: A Secure Global and Localized Mobility Management Scheme for Multihomed Mobile Nodes

Free registration required

Executive Summary

The evolution of Internet and its hosts does not match anymore the current Internet architecture, designed when mobility, multi-homing and security were not considered, and based on IP addresses with the double role of host's identity and host's topological location. In this paper, the authors propose a secure global and localized mobility management scheme suitable for multi-homed Mobile Nodes (MNs) and based on Host Identity Protocol (HIP) and Proxy Mobile IPv6 (PMIPv6). It merges the new identifier/locator split architecture proposed by HIP, especially designed for providing security and multi-homing to MNs, with the micro-mobility management scheme of PMIPv6, which has been proposed for unmodified MNs with future Global Mobility Management (GMM) protocols.
