Versatile Routing and Self-Certifying Features Support for Secure Mobility in eXpressive Internet Architecture

Integrating mobility and security in the network layer has become a key factor for Future Internet Architecture (FIA). This paper proposes a secure mobility support mechanism in eXpressive Internet Architecture (XIA), a new FIA currently under development as part of the US National Science Foundation's (NSF) program. Utilizing the natural features of ID/locator decoupling and versatile routing in XIA, a general mechanism to support host mobility is proposed. Exploiting the self -certifying identifier, a secure binding update protocol to overcome the potential threats introduced by the proposed mobility support mechanism is also given. We demonstrate that our design in XIA outperforms IP based solutions in terms of efficiency and flexibility. We also outline our initial design to illustrate one derivative benefit of an evolvable architecture: mobility support customizability with no sacrifice of architectural generality.NSFC [61672060]; National High Technology Research and Development Program of China (863 Program) [2015AA015701]SCI(E)中国科学引文数据库(CSCD)ARTICLE473-881
