摘要: 基于网络接入认证承协议与可扩展认证协议相结合的网络层认证架构,采用预认证与认证关联证书相结合,提出一种能够减少异构网络间切换中认证时延的网络层联合认证机制优化方法。通过与IEEE802.11i预认证、网络层辅助链路层预认证2种认证优化方法进行仿真比较,表明其有效降低异构网络间切换认证时延。

Abstract: Based on the network-layer authentication structure which relys on Protocol for carrying Authentication for Network Access(PANA) and Extensible Authentication Protocol(EAP), this paper adopts two ways of pre-authentication and authentication-associate certification, proposes a network-layer union authentication mechanism optimization way for reducing handover delay in heterogeneous networks. By simulating and comparing with IEEE 802.11i pre-authentication and network-layer-assisted pre-authentication, result on the proposed method demonstrates that the authentication delay of handover in heterogeneous networks is effectively decreased.
