Secure Authentication Protocol in Mobile IPv6 Networks

We propose new binding update protocol in Mobile IPv6. In our protocol, the home agent (HA) of each node creates Diffie-Hellman session key using middle key and safely transmits the middle key, cookie, etc via secure IPSec tunnel. These are used to generate secret keys in a mobile node (MN) and a correspondent node (CN). We present that the proposed protocol is satisfied with security requirements of key agreement protocol and shows the appropriate defense in existed attack scenarios.
