Research Of Secure Transmission Tunnel Based On Java

Internet is a open environment,and various information is transfered by common network every day.So to guarantee information transmission security is critical to guarantee security of Web system. A kind of secure tunnel to transfer information is used in the paper, and with the secure tunnel, to guarantee information transmission security in network.According to some kinds of existed attacking methods that were aimed at the web system,the feasibility to implement secure transmission tunnel on every layer in TCP/IP protocol,and the related secure protocol standard was discussed in the paper.And focusing on cryptography,the technologies of secure transmission of information were lucubrated,such as data encryption,digital signature,identity authentication and data integrality.Then,a model is constructed and kinds of secure transmission technologies were synthesized in this model.During the whole process of information communication,the encrytion, decryption,signature and authentication was implemented. And confidentiality,integrity,authentication and non-repudiation was ensured.With the secure tunnel,the problem of information transmission in the Web System was efficiently resolved; thus the network application will develop more quickly than today.Finally the secure tunnel was applied into a simple chat system in this paper.The core of secure transmission tunnel model was mainly implemented by Java language.System data was stored and accessed by My SQL Server in the background. The use steps were introduced. The solution's effectiveness was proved by typical examples and corresponding results.In the end, the summary was given.
