代理移动IPv6为移动节点提供了基于网络的移动性管理方法,移动节点不参与管理移动性信令.为了在移动互联网络中应用代理移动IPv6协议,需要定义安全有效的认证协议.目前还没有见到关于代理移动IPv6认证协议方面的研究,本文提出了一种代理移动IPv6的认证协议,该认证协议可以提供接入认证功能,并可防止重放攻击和密钥暴露.为了分析该认证协议的性能,本文给出了认证费用和认证延迟分析的解析模型,分析了移动性和流量参数对认证费用和认证延迟的影响.研究结果表明提出的代理移动IPv6认证协议安全有效.
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 defined 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 providing 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 cost and latency are analyzed,respectively. The results reveal that the proposed authentication protocol for Proxy Mobile IPv6 is secure and effective.
