基于Linux的无线局域网协议解析器的设计

无线局域网的快速发展使得对其安全性能的要求在不断提高。文中在对无线局域网安全机制分析的基础上,提出了一种基于Linux的无线局域网的协议解析器的设计方法。在Linux环境下,以目前运用最为普遍的无线局域网标准IEEE802.11b协议为基础设计协议解析器,详细介绍了系统的原理和体系组成。通过Libpcap数据包捕获开发包,捕获无线局域网传输过程中的数据包,并介绍了对所捕获到的符合过滤规则的数据包根据802.11b协议规范和TCP/IP协议簇中各协议的结构和特点进行解码。

Design of WLAN Protocol Parser Based on Linux

Rapid development of wlan has ceaselessly enhanced to its safe performance request.Design of a wlan protocol parser based on Linux has been presented, which based on analysing to wlan security mechanism.The protocol parser is implemented based on the most common use of wlan standard IEEE802.11b protocol under the environment of Linux and the theory and components of system have been introduced detailedly.Package of data is captured through the packet capture library of Libpcap and introduce the decoding process of data which meets the filtering rules,which is processed according to the criterion of 802.11b protocol and the structure and characteristic of various protocols in TCP/IP protocol bunch.
