【摘要】 宽带无线IP技术将无线通信技术和计算机网络技术有机的结合起来，它可使移动终端在无线传输信道上高速接入，并在网中漫游，实现真正意义上的移动办公。移动终端作为宽带无线IP网络的重要组成部分，面向最终用户，它的设计与实现至关重要。本文本着实用化的宗旨，以目前的主流操作系统Windows为开发平台，开发了无线网卡的驱动程序。在此基础上，为了方便用户对无线网卡进行配置管理，又开发了与其配套的配置管理软件，并已投入商业使用。同时本文还针对无线局域网的安全问题进行了探索和研究，分析了IEEE802.11无线局域网所提供的安全服务的缺陷，提出了基于数字证书系统的安全方案，完成了安全软件的开发，并建立了安全实验系统对该软件进行了测试。更多还原

【Abstract】 The effective combination of wireless communications and computer networking technology due to Broadband Wireless IP technology makes high-speed wireless Internet access a reality and enables Mobile Terminals to roam smoothly, which brings the real mobile office. Mobile Terminal, a critical part of the broadband wireless IP network, acts as the interface between end users and networks. Thus its design and realization are very important. With the purpose of putting things into practical usage, this paper presents driver software run on Windows platform for the wireless network interface card. Meanwhile, for the convenience of users, the corresponding configuration utility is developed as well, which is already commercially used in the market. Besides, we find that there exists a critical security problem within the 802.11 wireless networks. This paper presents a security scheme to meet the requirement for security services provided by wireless LANs. The scheme is based on the digital certificate system and a practical security system is finally set up. Security experiments are also done for software performance analysis.更多还原
