Security enhancement on an authentication method for proxy mobile IPv6

Abstract

Proxy Mobile IPv6 (PMIPv6) is an emerging network-based localized mobility management scheme. Recently, Zhou, Zhang and Qin proposed an authentication method for PMIPv6. However, this paper shows that their scheme fails to achieve mutual authentication between the Mobile Node (MN) and network. It performs only unilateral authentication of the MN to network, and the MN has no information about the authenticity of the network, thus it is susceptible to network spoofing attack and malicious MAG attack. Then, an improved scheme is proposed to remedy these security flaws. © 2011 Springer-Verlag Berlin Heidelberg.
