Ticket-based Binding Update Protocol for Mobile IPv6

Abstract

In this paper, we propose a new ticket based binding update protocol for Mobile IPv6. This protocol uses CGA (Cryptographically Generated Address) to provide mutual authentication between a mobile node and its corresponding node, but differs from previous protocols in the following way. The protocol does not require a mobile node to generate a signature each time it acquires a new IP address. To minimize computational cost of using CGA, the corresponding node issues a ticket that can be used in later update requests. Our initial protocol requires similar computational cost compared to previous protocols based on CGA, but outperforms others when a mobile node has a valid ticket.
