基于SSL协议的VPN系统实现及安全性研究

Security Research and Implementation of VPN System Based on SSL Protocol

通过对SSL协议的分析研究,在Linux操作系统环境下,利用开源软件OpenVPN实现基于SSL协议的VPN系统。使用Wireshark抓包分析工具对OpenVPN系统性能进行测试分析,结果表明该系统有效解决了数据传输的安全性和可靠性问题。最后采用Grails开发框架设计了基于Web的文件分发系统,解决OpenVPN系统用户端证书、密钥等文件的安全分发问题。

Based on the analysis of SSL protocol, under the Linux operating system environment, open source software OpenVPN was utilized to implement the VPN system based on the SSL protocol. The performance of OpenVPN system was tested and analyzed by using Wireshark capture tool, the results showed that the system can effectively solve the problem of security and reliability of data transmission. Finally, using Grails development framework to design a file distribution system based Web, and to solve the security problems of the OpenVPN system, such as the user＇s certificate, key, etc.
