A Study of an Integrated Security Handover Scheme for Hierarchical Mobile IPv6 based Multimedia Convergence Networks

Hierarchical Mobile IPv6 introduces a new node called the Mobile Anchor Point (MAP) to improve the handover speed performance of Mobile IPv6 by reducing the amount of signaling in the ongoing connection between the mobile node, its correspondent nodes, and its home agent. With MAP as an additional node, it’s signaling, both received and sent is subject to several security vulnerabilities that needs addressed. Authentication and authorization of Binding Updates (BUs) to the MAP is essential during the registration process. This paper deals with securing the hierarchical mobile IPv6 handover scheme by adding a cryptography procedure for authenticating the binding updates sent by mobile nodes during the mobile anchor point registration process.
