The miniaturization of the computing machinery increases needs for using mobile computing of users. In this situation, Mobile IPv6 Working Group of Internet Engineering Task Force (IETF) suggests IPSec for Mobile IPv6 security. IPSec, however, has a long latency problem of dynamic security authentication due to the key management and a large amount of calculation. We therefore apply AAA in Mobile IPv6 to solve a dynamic security authentication problem of IPSec and simultaneously use Fast Handover technique for quick mobility. And we propose a method for reducing a long latency caused by authentication of mobile node (MN) during a handover. Old and new access routers authenticated by a hash value of an MN are able to reuse existing Security Authentication (SA) for a certain time and reduce latency for new SA. As a consequence, a mobile node can provide the real time services due to the reduction of authentication latency. Also, we can trust the buffered information through the tunnel between two access routers.
