基于应用层VPN安全组网模型的研究

Research of building secure VPN network mode based on application layer

在分析当前网络缺陷的基础上,设计并实现了一种安全可靠的VPN组网模型.该模型采用VPN over HTTP协议和Kerberos认证,从而确保了通信各方身份和数据传输的安全.给出了该组网模型服务器和客户端主要算法和工作流程.测试表明,该模型在服务的最大连接数、系统吞吐量和数据加密等方面具有很好的性能,完全适合当今网络发展的需求,在远程安全传输方面有着很好的应用前景.

On the basis of analyzing VPN network＇ s flaw, this paper designed and implemented a secure and reliable VPN networking model. The model adopts VPN over HTTP protocol and Kerberos to ensure the secure of identification authentication and data transmission. This paper also gave the main algorithm and workflow of the model＇ s Server and Client. Test results demonstrate that this model has better performance in maximum number of connection, throughput of system, data encryption, etc. The model suites to the needs of network development, has a very good application prospects on secure transmission of the remote.
