An Efficient Handover Authentication Scheme Based on HMAC for Proxy Mobile IPv6 Network

Abstract

Proxy mobile IPv6 plays a significant role in optimizing the performance of mobile IPv6 and achieving
the support for network mobility management. But the open nature and lack of security consideration
result in potential threat. The requirement of the real-time application of mobile node leads us
to develop a handover authentication scheme which satisfies certain security and efficiency needs. In
this paper, based on the 2-HIBS scheme, the handover authentication scheme is implemented by utilizing
hash-based message authentication code (HMAC). The proposed scheme makes an excellent
combination between initial access authentication and handover authentication procedures. We also
evaluate the handover authentication latency between our scheme and other authentication schemes.
The results show that our scheme has higher efficiency and lower communication cost than existing
ones.
