Improved Authentication Scheme of Binding Update Protocol in Mobile IPv6 Networks

We propose the efficient and secure Ticket based Binding Update (TBU) protocol for MIPv6 networks. In our TBU protocol, when MN first executes the BU, its Correspondent Node (CN) issues a ticket to MN. This ticket assist that it is able to do efficiently the BU whenever Mobile Node (MN) requires the BU for the future. The proposed TBU protocol need not be repeated equal BU course whenever the MN moves to foreign link or network, and is able to be executed in environment of not operating the Home Agent (HA), and also easies scalability. We describe security analysis through attack scenarios by comparing previous protocol schemes.
