【摘要】 计算机网络对人类生活和社会发展的冲击是其它信息载体所无法比拟的,它的高速发展和全方位渗透,推动了整个社会的信息化进程。本文设计和实现了基于虚拟专用网络(VPN)的远程网络控制系统(Network Management System)。本系统可对局域网内被监控计算机的上网情况进行实时管理和控制,并可以远程控制被监控机。 论文的主要工作如下: 1.对跨子网通讯的模式进行了分析和对比,采用基于IPSec安全协议的虚拟专用网络隧道传输模式,设计了系统的原型; 2.详细设计了远程网络控制系统,详细讨论了相关的关键技术; 3.设计实现了基于IPSec安全协议的Linux系统网关; 4.对IPSec安全协议的模式和数据处理过程进行了分析与探讨,并详细描述了本系统守护模式的设计和实现; 5.使用COM组件同IE浏览器进行互操作的模式,解决了难点问题; 6.通过系统实际运行情况和系统的安全性、可靠性测试,验证了系统的正确性和有有效性。更多还原

【Abstract】 Computer network is quit important to human’s life and society developing. Its high-speed developing and using in many fields drives the information developing of the whole society. Especially Internet is changing and affecting everyone’s life. In this thesis, we design and develop the Long-distant Network Control and Management System Based On Virtual Private Network. The system can control and mange the IE explorer in the computers under real-time control. Through this way, we can protect the computers and make the users browse the legal websites.The content of this thesis is as follow:1. Some modes of the communications in some different subnets were analyzed and compared in the thesis. The prototype of Network Control and Management System(NCMS) have been designed ,which based on IPSec protocol and Virtual Private Network’s tube mode.2. The details design of NCMS were described carefully. And some important key points were discussed deeply.3. The gateway of Linux which based on IPSec have been designed and implemented.4. The security model of IPSec protocol .and date processing have been analyzed. And the design of guardianship mode is described in detail.5. Using the model of COM modules operating IE explorer, the most difficulty problems were solved.6. Through system execute in real world and some test on system security and reliability, the NCMS is validated correctly and effectively.更多还原
