Abstract
The Intra-Domain Mobility Management Protocol (IDMP) provides a mobility solution for mobile nodes in next generation wireless networks. Thus, it is necessary to set up security associations between the mobile node and the entities that provide connectivity and mobility in the IDMP environment. We propose a framework of Authentication, Authorization and Accounting (AAA) architecture for the Intra Domain Mobility Management Protocol. This AAA architecture provides authentication and encryption for mobile nodes within the home domain as well as in the foreign domain.
