Abstract

Mobile IP proposed by IETF supports continuous services for a mobile node (MN) based on its capability to roam around foreign domains. Recently the significance of the security for MN has been recognized. When it roams around a foreign domain, the authentication, authorization, and accounting (AAA) for the MN must be done at the foreign domain. For this reason, the IETF suggests that the existence of some servers capable of performing AAA services could help. In this paper, we propose a new mobile initiated handoff mechanism using an IDentification Key (IDK) that supports authentication and authorization for the MN, and reduces delay and the risk in authentication. The performance evaluation results show that the use of IDK for an MN in AAA model reduces the latency up to 40% while maintaining the similar level of security to the previous works.
