Proxy Mobile IPv6 provides a means of network-based mobility management for mobile nodes without involving the mobile nodes themselves in the mobility signaling.To make Proxy Mobile IPv6 protocol feasible in mobile Internet,a new de-fined authentication protocol should be accompanied. To the best of our knowledge, no studies have been conducted in the area of Proxy Mobile IPv6 authentication protocol. This paper proposes an authentication protocol in Proxy Mobile IPv6. In addition to pro-viding access authentication, the proposed authentication protocol prevents threats such as replay attack and key exposure. Also, we develop analytic models for the authentication latency and cost analysis.Then, the impacts of mobility and traffic parameters on the authentication cast and latency are analyzed,respectively.The results reveal that the proposed authentication protocol for Proxy Mobile IPv6 is secure and effective.
