Diffie-Hellman算法通过密钥交换的方式为企业VPN网络的信息传输提供数据机密性，其有效性依赖于计算离散对数的难度。在描述算法过程的基础上，利用Visual C++语言编程并在Windows XP环境中编译。通过一个具体的企业VPN网络部署和配置，实现了企业内网对等体之间通过VPN隧道的相互通信和对Internet资源的访问，分析了由于加载VPN数据包而对网络性能产生的影响，主要体现在网络吞吐量和网络延迟的变化上。因此提高VPN网络的应用性能和数据传输的质量是今后研究的主要方向。

Diffie-Hellman algorithm provides data confidentiality for information transmission through VPN network of enterprise by the mean of key exchange,its validity depends on the difficulty of computing discrete logarithm.On the basis of describing the algorithm process, the algorithm was programmed using Visual C++ programming language and compiled in the Windows XP operating system.Through the deployment and configuration of a specific enterprise VPN network,the communication was realized between peer of enterprise intranet and internet resource could be accessed,the influence,such as network throughput and network delay,was analyzed causing by loading VPN packets on network performance.Therefore,it is the main direction of future research to improve the application of VPN network performance and the quality of the data transmission.
