基于Libnet/Libpcap的Linux 802.1x无线客户软件设计与实现

Design and Implementation of Linux 802.1x Wireless Client by Libnet/Libpcap

无线接入认证是关系到无线网络安全的重要课题之一。在回顾802.11 i中采用的802.1x认证技术基础上,对在Linux平台下802.1x无线客户端如何实现安全接入与认证进行深入研究,并提出采用Libnet/Libpcap开发包设计和实现无线帧的封装与收发的解决途径。在Linux平台下给出了一种较为通用的设计实现无线数据链路层802.1x客户软件的解决与实现方案,提高无线局域网的安全性和可扩展性,有效保护无线网络资源的安全。

Wireless access and authentication are important issues in wireless network security. The paper first reviews the 802. lx authentication technique in IEEE 802.11i, then explores the secure access and authentication on Linux wireless client, and brings a way to encapsulate, send and receive wireless frames using Libnet/Libpcap developing packages. The paper has given a common solution to design and realize an 802.1 x authentication client in the data link layer under Linux platform, so as to get more WLAN security and extensibility, and more protection to the WLAN resources.
