Lightweight Security Solution for Host-Based Mobility & Multi-homing Protocols

Host-based mobility and multi-homing protocols allow hosts to change their location or network interface during ongoing sessions in a cost-efficient, technology-agnostic manner. Since these solutions enjoy resurgence with the rise in mobile internet traffic, they are faced with the problem of providing sufficient security without impairing the economical benefits. We present a light-weight security solution to protect such protocols against redirection and DoS attacks. Our solution combines methods of weak authentication with proof of session ownership. We discuss how this solution creates a level of protection that requires more (sometimes significantly more) effort to break than conducting corresponding attacks using the existing Internet signaling.
