Embodiment 1

[0018] The embodiment of the present invention provides a file transfer method based on a one-way security isolation gatekeeper.

[0019] figure 1 It is a flowchart of a file transfer method based on a one-way security isolation gatekeeper according to an embodiment of the present invention. Such as figure 1 As shown, the file transfer method based on the one-way security isolation gatekeeper comprises steps as follows:

[0020] Step S102, the first processing module receives the data sent by the low-level network server;

[0021] Specifically, in the above step S102, the low-secret network server cannot directly establish an FTP connection with the high-secret network server through the one-way security isolation gatekeeper; but the first processing module is directly connected to the low-secret network server, and can use the FTP protocol to communicate with the low-secret network server. Confidential web server interaction data. Since the FTP protocol uses the TCP proto...

Embodiment 2

[0064] The embodiment of the present invention also provides a file transmission device based on a one-way security isolation gatekeeper. The device can realize its function through the file transfer based on the one-way security isolation gatekeeper. It should be noted that the file transfer device based on the one-way security isolation gatekeeper in the embodiment of the present invention can be used to implement the file transmission method based on the one-way security isolation gatekeeper provided in the embodiment of the present invention. The file transfer method of the one-way security isolation gatekeeper can also be executed by the file transmission device based on the one-way security isolation gatekeeper provided by the embodiment of the present invention.

[0065] figure 2 is a schematic diagram of a file transfer device based on a one-way security isolation gatekeeper according to an embodiment of the present invention. Such as figure 2 The shown file trans...

Abstract

The invention discloses file transmission method and device based on an one-way safety isolation gap. The method comprises the steps of receiving data by a first processing module from a low-confidentiality-level network server; determining the type of the received data through the first processing module; transmitting the file to an isolation plate card if the data are the file data; reading the file data through a second processing module from the isolation plate card; uploading the file data to a high-confidentiality-level server through the second processing module. With the adoption of the method, the problem that a file is inconvenient to be transferred from the low-confidentiality-level network server to the high-confidentiality-level network server through the client in the prior art can be solved.

Description

technical field [0001] The invention relates to the Internet field, in particular to a file transfer method and device based on a one-way security isolation gatekeeper. Background technique [0002] The one-way transmission technology without feedback can ensure the one-way flow of data from the low-density network to the high-density network, which solves the problem of high-density network information leakage during data transmission. The one-way security isolation gatekeeper has the characteristics similar to the one-way conduction of a diode. It adopts a hardware architecture design so that data can only be transmitted from the low-density network terminal of the external network, that is, the untrusted end, to the high-density network terminal, that is, the trusted end. The one-way security isolation gatekeeper can ensure the absolute one-way flow of data from the physical link layer and the transport layer. However, it is precisely because of the one-way flow of infor...
