Security in Mobile IPv6: A survey

Secure mobile communication is essential for the pervasive accessibility of critical information infrastructure. Connecting control systems with the business enterprise, wireless telemetry and mobile user interaction with critical infrastructure systems are examples of services that motivate the need for secure mobile communication. Mobile IPv6 is being touted to provide communication support for such services. The security of Mobile IPv6 poses key challenges impeding its wide-scale adoption. Several security mechanisms have been proposed in the literature. This paper surveys security vulnerabilities of Mobile IPv6, provides a taxonomy for the main existing and proposed solutions, and then extends to outline some open issues.
