IP version 6 (IPv6) Is being designed within the IFTF as a replacement for the current version of the IP protocol used in the Internet (IPv4). We have designed protocol enhancement for IPv6, known as mobile IPv6, that allow transparent routing of IPv6 packets to mobile nodes, taking advantage of the opportunities made possible by the design of a new version of IP. In Mobile IPv6, each mobile node is always identified as by its home address, regardless of its current point of attachment to the Internet. While away from its home Ip subnet, a mobile node is also associated with a care-of address, which indicates the mobile nodes current location. Mobile IPv6 enables any IPv6 node to learn and cache the care-of address associated with a mobile nodes home address, and then to sent packet destined for the mobile node directly to it at this care-of address using an IPv6 routing header. But there are many security risks involved, when a malicious node might be able to establish a connection with the mobile node by sending the false binding messages. By doing so malicious node can divert the traffic, can launch the DOS Attacks and can also replay the authenticated messages.
