Problems solved by technology

[0007] (2) The HTTP service requires an open service port (such as port 80), which makes it easy for attackers to use this port to control the server;
[0008] (3) There is no encrypted transmission of data on the Internet, and there is a possibility of being intercepted and leaked

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the firewall channel is connected by the internal BE gateway server and the external FE gateway server through SSL. When the client access terminal sends an access request to the computer terminal user, the request information is first encrypted and packaged by the service program of the FE gateway server, then transmitted to the BE gateway server through an SSL connection, and then unpacked by the service program of the BE gateway server and then sent to computer end users.

[0021] After the computer terminal user obtains the access information of the client access terminal, the response information is encrypted and packaged through the service program of the BE gateway server, and then the SSL connection is transmitted to the FE gateway server, and then unpacked by the service program of the FE gateway server and sent to the client...

Abstract

From inner BE gateway server through SSL, firewall channel builds connection with FE gateway server. When client access end sends an access request to user at computer terminal, the information of request is encrypting packed by a service program at FE gateway server first. Next, through SSL connection, the packed information is transmitted to BE gateway server. Then, Unpacked by service program at BE gateway server, information is sent to user at computer terminal. After receiving the access information from the client access end, user at computer terminal sends out response information to the client access end through following steps: the response information is encrypting packed by a service program at BE gateway server first. Next, through SSL connection, the packed information is transmitted to FE gateway server. Then, unpacked by service program at FE gateway server, the response information is sent to the client access end.

Description

technical field [0001] The invention relates to computer network technology, in particular to a method for establishing a firewall channel by using the SSL (SecuritySocket Layer) protocol to realize a virtual private network. Background technique [0002] With the development of information technology, especially the development of the Internet, it has become more and more convenient for people all over the world to communicate. However, due to the need to protect personal information, various methods have to be used, among which firewalls are used to prevent Illegal attacks on servers and their personal information are the most common method. [0003] Firewalls play a role in protecting personal information and preventing unauthorized access to computer terminals by hackers, but there is also the possibility of denying legitimate users access. [0004] In order to enable users located outside the personal user firewall on the Internet to access information resources inside...
