Securing Host-Based Mobility and Multi-Homing Protocols Against On-Path Attackers

Free registration required

Executive Summary

Host-based mobility and multi-homing protocols allow hosts to migrate ongoing transport sessions between networks or network interfaces. While such protocols can facilitate vertical mobility in a cost-efficient and access-agnostic manner, they are hard to secure when strong authentication between end points is not available. The authors present a balanced security solution which protects these protocols against redirection- and DoS attacks performed by on-path adversaries, while demanding only insignificant processing overhead on the end nodes.
