基于Winpcap的网络嗅探器设计与实现

网络安全课程设计 设计题目：基于 Winpcap 的网络嗅探器设计与实现院系名称：班 级: 小组成员:秦向红 贾 博指导老师：孙飞显、夏冰2024 年 1 月摘 要当前,网络也逐渐成为人们生活和学习中不可缺少的部分,与此同时,网络信息安全性也越来越受到人们的关注。为了有效地实现网络传输中数据包的检测、捕获和分析，较为方便地监控网络信息流量并保证信息的安全可靠，产生了网络嗅探器.基于 Winpcap 开发平台,使用 Visual C++作为开发工具,设计并开发网络嗅探器。设计实现 IP、TCP、UDP 数据包捕获和分析,以有效地对网络信息的安全进行监测、捕获和分析 。同时分析了网络嗅探器的基本工作原理,并阐述了应用捕获数据包流,根据 Winpcap 关键功能给出了其具体实现。结果表明,该网络嗅探器结构简单,捕获数据快速，对网络安全管理具有重要意义。关键词：Winpcap、MFC、网络嗅探器、数据包AbstractAt present, the network has gradually become an indispensable part in people life and learning， at the same time， network information security has been paid more and more attention. In order to achieve the capture and analysis of detection, data packet in the transmission network, more convenient monitoring network information flow and ensure the safety and reliability of the information ， produced a network sniffer。 Based on the Winpcap development platform ， using Visual C++ as the development tool， the design and development of network sniffer 。 Design and implementation of IP, TCP， UDP data packet capture and analysis ， monitoring, capture and analysis in order to effectively on the security of network information 。 At the same time， analyzes the principle of network sniffer ， and expounds the application of capturing packet stream， according to Winpcap key function gives the concrete realization. The results show that， the network sniffer has the advantages of simple structure ， fast capture data ， has the vital significance to the network secu...
