Data transmission method, transit server and access network point server

Abstract

The invention discloses a data transmission method, a transit server and an access network point server, and the method comprises the steps: building a first TCP connection with a central network point server, and enabling the built first TCP connection and a network point identifier of the central network point server to be stored in an associated manner; establishing a second TCP connection withan acceleration server, and receiving an SSL connection request which is forwarded by the acceleration server and points to the central network server through the second TCP connection; and binding the second TCP connection and the first TCP connection according to the network point identifier of the central network point server, so as to transmit encrypted data between the access network point server and the central network point server through the first TCP connection and the second TCP connection. According to the technical scheme provided by the invention, the security of data transmission can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data transmission method, a transfer server and an access network point server. Background technique [0002] At present, in order to improve the security of network data transmission, VPN (Virtual Private Network, virtual private network) technology is used more and more. see figure 1 , in order to save the deployment cost of the VPN system, it is usually necessary to deploy a public network server on the public network. The two ends (client and intranet device) that need to exchange data in the VPN system can respectively connect to the public network server through encrypted links, so as to realize data exchange through the public network server. [0003] However, such a data transmission method will have security risks. The reason is that the data transferred in the public network server needs to be decrypted into plain text. Once the public network server is hacked,...

Problems solved by technology

[0003] However, such a data transmission method will have security risks. The reason is that the data transferred in the public network server needs to be decrypted into plain text. Once the public network server is hacked, the data transmitted between the client and the intranet device will be leaked.

Therefore, this data transmission method in the prior art cannot guarantee the data security of both communication parties
