A data transmission method, a transfer server, and an access point server

Abstract

The invention discloses a data transmission method, a transfer server and an access network point server, wherein the method includes: establishing a first TCP connection with a central network point server, and connecting the established first TCP connection with the central network point The network point identification association storage of server; Establish a second TCP connection with the acceleration server, and receive the SSL connection request directed to the central network point server forwarded by the acceleration server through the second TCP connection; according to the network point identification of the central network point server, Binding the second TCP connection and the first TCP connection, so as to transmit the encrypted data between the access network point server and the central network point server through the first TCP connection and the second TCP connection data. The technical solution provided by this application can improve the security of data transmission.

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
