In this paper, we propose the fast and secure binding update protocol as handoff or handover in the micro and pico environment based on mobile IPv6. The nodes or routers on participating in this protocol generate their addresses from cryptographically generated addresses (CGAs) method unlike previous address generation method. The mobile node (MN) includes in home network or home link has limited power and computational abilities. So the home agent (HA) of the MN executes key agreement protocol with the correspondent node (CN) on behalf of the MN. The CN then creates a ticket on including session key, lifetime of ticket. and so on. It then transmits it to the MN via the HA of the MN. The ticket is used to communicate directly between the MN and its CN. In performance analysis, we analyze security of proposed binding update protocol under various attack scenarios and efficiency by comparing proposed protocol with prior binding update protocols. Finally we make a conclusion of this paper and present future works.

Next-Generation ITS environment requires high-speed data packet transmission, security, authentication, and hand-over supportable for driving vehicle on road by installing RSEs and OBUs. Therefore, wireless communication technology for next-generation ITS services are advancing to 200km/h maximum speed supportable, 1km communication radius, minimum 10Mbps hish-speed datarate for multimedia data(such as text, images, movie clips and so on) supportable, high reliability. In this paper, we implemented WAVE communication system which based on IEEE 802.11p PHY/MAC and evaluated that the system meets next-generation ITS environments.
