Research Of Secure Transmission Tunnel Based On WEB

A number of the digital applications, such as E-Business, E-Government, OA, are growing up in the global range with rapid progress of Internet. The mode of life is also profoundly changing. However, the status of the network security is becoming worse at the same time. Furthermore, the security problems restrict the farther development of the Internet.According to some kinds of existed attacking methods that are aimed at the Web system, the article discusses the feasibility to implement secure transmission tunnel on every layer in TCP/IP protocol, and the related secure protocol standard. And focusing on cryptography, the paper lucubrates the technology of secure transmission of information such as data encryption, digital signature, identity authentication and data integrality technology. Then, a model is constructed that synthesizes kinds of secure transmission technology. During the whole process of information communication, the model implements the encrytion, decryption, signature, authentication, and ensures confidentiality, integrity, authentication and non-repudiation.With the security tunnel, the problem of information transmission in the Web System can be efficiently resolved; thus the network application will develop more quickly than today. In short, the article proposes a new scheme for resolving the problem of security, which can be put into practice and has a broad prospect.
