New Authentication Mechanism with Home Agent in Next Generation Mobile Internet Protocol - Version6 (MIPv6)

This paper presents a secure authentication method for Mobile IPv6 with Home Agent. As a default IPsec is used for secure signaling messages between the Mobile Node and other agents in Mobile IPv6 networks. Mobile IPv6 message transactions include the Binding Updates and Acknowledgement messages as well. We propose a new mechanism for securing Mobile IPv6 signaling between Mobile Node and other agents. The proposed method consists a Mobile IPv6 message authentication option and cookie management that can be added to the current protocols for securing IPV6. In new authentication mechanism with Home Agent the Mobile Node is connected to Home Agent. So the transmissions of data are secured. Authentication Protocols of Mobile IPv6, Some difficulties for satisfying timing requirements. We show the latency can be decrease between the Mobile IPV6 node, Home Agent and Correspondent Node with creating a cookie file keeping the mobile node identification.
