Problems solved by technology

However, the gatekeeper cannot guarantee the security of the data it allows. Therefore, the data entering the private network still has potential security risks, which may endanger the security of data in the private network.

Embodiment approach

[0048] In this embodiment, the front-end processor 12 obtains the current authority of the preprocessed text file by querying the file attribute of the preprocessed text file, and judges whether the authority represented by the current file attribute of the preprocessed text file is consistent with the preset authority unanimous. Wherein, when they are consistent, the front-end processor 12 determines that the preprocessed text file satisfies the preset condition.

[0049] As another implementation, the preset condition may be that the authority of the pre-processed text file is consistent with the above-mentioned preset authority, and the file size of the pre-processed text file is the file size corresponding to the file size information obtained in advance by the front-end processor 12 unanimous.

[0050] In this embodiment, the front-end processor 12 obtains the current authority of the preprocessed text file by querying the file attribute of the preprocessed text file, an...

Abstract

The invention relates to a one-way secure transmission method and a data transmission system for heterogeneous network data access, which belong to the field of data transmission and are applied to a data transmission system. The data transmission system is used to connect a data sending network and a data receiving network. The method includes: obtaining the text file transmitted by the data transmission network through FTP; changing the authority of the text file to a preset authority to obtain a pre-processed text file; checking whether the pre-processed text file meets a preset condition; When it is determined that it is satisfied, the preprocessed text file is sent to the data receiving network. Through this method, the data security of the data receiving network can be guaranteed.

Description

technical field [0001] The application belongs to the field of data transmission, and in particular relates to a one-way secure transmission method and a data transmission system for heterogeneous network data access. Background technique [0002] With the explosion of Internet information, data is growing exponentially. However, due to the increasingly serious situation of data silos, cross-network transmission is unavoidable when data is interacted. [0003] There are network boundaries between different networks. In order to ensure the data security of some networks (such as private networks) that involve data confidentiality, a gatekeeper is installed at the network boundary of the private network. When performing necessary cross-network transmission, the network gatekeeper Only the data of the allowed different network can enter the private network. However, the gatekeeper cannot guarantee the security of the data it allows. Therefore, the data entering the private ne...
