Towards a Secure and Seamless Host Mobility for the real world

Research output: Contribution in Book/Report/Proceedings - With ISBN/ISSNConference contribution/Paperpeer-review



Mobile IPv6 has been developed for quite a few years now, but it has yet to bring its constant connectivity and global reachability benefits to mobile devices in real world scenarios, mainly due to lack of trouble-free and secure network access and data transmission for devices as they roam. In this paper we propose a Unified Architecture that combines the strengths of Mobile IPv6 and AAA services and closes the gap between the Mobile Node and the Access Network’s requirements. Our approach provides a comprehensive solution in a setting where users require seamless roaming, secure network access and secure data transmission in a dynamic fashion as they commute, whereas Access Networks require powerful AAA services without compromising their security policies. The qualitative and quantitative evaluation of our Unified Architecture through thorough laboratory tests, demonstrate the efficiency of our approach and highlight its potential and suitability for real world deployment in the current Internet architecture.
