【摘要】 在分析IPSec VPN与SSL VPN各自优劣势的基础上,提出了一种基于Web浏览器的SSLVPN网关系统的体系结构并给出了具体的实现方法。系统主要由HTTP协议代理Applet、VPN网关上的Web服务器和VPN反向代理服务器组成。系统提供了两种安全访问内网的模式,即隧道模式和替换模式。用户直接通过浏览器从VPN网关上下载Applet或点击用户界面中提供的资源列表就可以安全地访问内部网络中的资源。更多还原

【Abstract】 On the basis of analysis of advantages and disadvantages of IPSec VPN and SSL VPN,a design and implementation of the SSL VPN gateway system,which is based on the web browser,is proposed.The system is composed of proxy applet of HTTP protocol,web server and VPN reverse proxy server on the VPN gateway.The system provides two ways of accessing intranet securely,i.e.Tunnel mode and replacement mode.The applet is downloaded from the VPN gateway or click the resource list in user interface,and then web browser is used to access resources of Intranet.更多还原
