Dual identity return routability for the security of mobile Ipv6 binding updates within the distributed authentication protocol

The future fourth generation 4G networks will provide us with a paradigm shift in how mobile telecommunications will operate. It will be solely based on packet switching using mobile IPv6. However binding update route optimisation is vulnerable to a variety of security attacks. This paper attempts to reduce the security vulnerabilities by creating a new security protocol by first investigating the possible future technologies which may be incorporated into 4G mobile phones. Various technologies such as WI-FI and WiMax will be looked at but one in particular may be of particular interest, sim cards which allow the user to have multiple phone numbers. Using this technology and combining it with the established security protocol return routability, a new enhanced security solution is created called Dual Identity Return Routability. This solution provides an enhanced reachability test and a cheap authentication method, which can be incorporated into the distributed authentication protocol or be used as a stand-alone solution.
