基于预认证的WiFi/WiMAX混合网络安全模型

由于WiFi高的数据传输能力和WiMAX更大的覆盖范围，集成的WiFi/WiMAX网络在将来有很大的发展潜力。针对无线网络中实时业务低时延的需求，提出了一种WiFi/WiMAX混合网络中的快速安全认证模型。该模型基于EAP-TLS协议，将认证过程分为两个阶段：预认证和重认证。通过采用预认证，当MS在WiFi和WiMAX之间切换时，大大减少了认证延时，能在一定程度上支持混合网络中的实时服务。

Secure model in WiFi/WiMAX mixed networks based on pre-authentication

The integrated WiFi and WiMAX network is of great potential for the future due to the high data transport capacity of WiFi and the wider coverage of WiMAX. According to the requirements for real-time service in the wireless network, a fast secure authentication model in the WiFi/WiMAX mixed networks is proposed. It is based on the EAP-TLS protocol and its authentication procedure is divided into two stages：pre-authentication and re-authentication. By the utilization of the pre-authentication the authentication delay is reduced significantly when a MS roams between WiFi and WiMAX networks, which can be used to support real-time service in the mixed wireless network to some extent.
