利用NDIS技术实现虚拟专用网安全隧道

虚拟专用网技术解决了远距离局域网间的资源互访问题，使得在不同地区拥有多分
支机构的单位能够合理、有效地利用内部信息。隧道技术是实现虚拟专用网的关键技术之一，由于受到开发平台的制约，目前关于隧道技术的研究主要集中在Linux 等源代码开放的平台，对Windows 平台则很少涉及。为此，本文利用NDIS 技术，提出了Windows 平台下虚拟专用网安全隧道技术的解决方案，并通过实验对其可行性进行了验证。验证结果显示，该技术方案能够在Windows 平台下实现安全隧道的主要功能，具有较广泛的应用前景。

Abstract: VPN technology resolves the puzzle on how to visit resources of LAN in different area. It affords the technology to access information effectively in multi-branch unit. The tunnel technology is the key to implement the VPN. Because of the limit of implement environment, the implement technologies of the tunnel model emphasize on Linux which code is opened, and pay less attention to Windows. So, this paper proposes a VPN security tunnel development scheme on windows with NDIS technology and verifies its feasibility by experiments. The results show that this technology scheme can implement mainly functions of security tunnel and has more extensive application prospects.
