Security model for Intra-Domain Mobility Management Protocol

Intra-Domain Mobility Management Protocol (IDMP) provides a mobility solution for mobile nodes (MNs) in next-generation wireless networks. It provides a solution for intra-domain mobility without assuming the existence or use of any global mobility management protocol. It is, therefore, necessary to set up security associations between the mobile node and the entities that provide connectivity and mobility in the IDMP environment. In this paper, we propose a security model for Authentication, Authorisation and Accounting (AAA) for IDMP. This AAA architecture provides authentication and encryption for MNs within the home domain as well as in the foreign domain. Simulation results verify the validity of the proposed security model.
