An efficient performance enhancement scheme for fast mobility service in MIPv6

As secure mobility service is becoming a critical issue in the ubiquitous environment, the Mobile IP Working Group in IETF is preceding the research about it. If it provides weak security features to the mobile service, then the Mobile IPv6 will not be trusted. Although the IPSec (Internet Protocol Security) and RR (Return Routability) was selected as the methods for providing security supports and related works have been obligated, these approaches have drawbacks that the hand-held devices such as cellular phones and PDAs are battery-powered so the security processing is a big burden and security feature is not relatively abundant. To cope with these drawbacks, we propose the integrated models with AAA infrastructure as an alternative way to authenticate a mobile node by using the AAA authentication processing. In this paper, our research has a focus on minimizing the authentication latency in AAA processing and proposes the model with Fast Handoff scheme to make the better performance to AAA authentication delay.
