一种基于隧道的SSLVPN的研究与实现

Research and Implementation of SSL VPN Based on Tunnel

阐述SSL VPN的概念,特点以及SSL VPN的关键技术之一-安全隧道技术,并在实验室模拟Internet,利用开源软件OpenVPN实现了一个基于隧道的SSL VPN系统.对实验进行测试,测试结果表明:通过开源软件OpenVPN建立的安全隧道,很好地对客户端和服务器之间的通信数据进行加密,保证SSL VPN服务的安全性,从而以较低的费用实现了一个SSL VPN系统,为SSLVPN在中小型企业的应用做好铺垫.

Expounding the concept and features of SSL VPN and one of the key technologies to achieve a SSL VPN system-security tunnel technology, we simulated Internet and implemented SSL VPN system with Open VPN in the laboratory. Finally, we made a test of the experiment. The results showed that： the secure tunnel, which established with the open-source software Open VPN, encrypted the communication data between the client and the server, and the security of the SSL VPN services is ensured, so implemented a SSL VPN system with the lower cost is implemented, and it paves the way for the small and medium-sized enterprises in the SSL VPN application.
