Embodiment Construction

[0060] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0061] According to the research of the applicant, the data interaction under the existing branch-headquarters network architecture realizes the secure data transmission between the branch and the headquarters by setting up a separate link encryption gateway at each terminal, and there is a problem of high cost of hardware equipment. However, using software directly at the terminal to ensure secure transmission without using a link encryption gateway connected to the terminal will have security problems, and it is not suitable for data transmission scenarios with high security requirements.

[0062] In order to solve the above problems, the embodiment of this application provides a data security transmission system 10, please refer to image 3 , image 3 It is a schematic structural diagram of a da...

Abstract

The invention provides a data security transmission method, system and device and a storage medium, and relates to the technical field of network security. The method is applied to a first link encryption gateway in communication connection with one or more terminals, the first link encryption gateway is also in communication connection with a second link encryption gateway, and the method comprises the following steps: receiving a first encrypted message sent by a terminal; determining that the first encrypted message passes the authentication; decrypting the first encrypted message to obtaina first decrypted message; encrypting the first decrypted message based on an encryption mode agreed with a second link encryption gateway to obtain a second encrypted message; and sending the secondencrypted message to a second link encryption gateway through a secure channel between the second encrypted message and the second link encryption gateway, so that the second link encryption gatewaydecrypts the second encrypted message and sends the decrypted second encrypted message to the server. According to the method, a plurality of terminals share one link encryption gateway, and an independent link encryption gateway does not need to be arranged at each terminal, so that the hardware cost is reduced.

Description

technical field [0001] The present application relates to the technical field of network security, in particular, to a method, system, device and storage medium for secure data transmission. Background technique [0002] Under the traditional branch-headquarters networking architecture, there is data interaction between the branch and the headquarters, such as figure 1 As shown in the figure, PC1 accesses the headquarters server. For the sake of security, the data between PC1 and the headquarters server needs to be encrypted. The usual encryption method is to establish an IPsec VPN and enable the IPsec VPN function on the egress router. For example, between router 1 and router 2 Establish IPsec (Internet Protocol Security, Internet Security Protocol) VPN (Virtual Private Network, virtual private network) between, but after establishing IPsec VPN, can increase a layer of tunnel protocol header and include the header of tunnel termination source address and destination address...
