Description

A method for one-way file transfer across secret levels

technical field

The invention relates to the field of encrypted communication, more specifically, it relates to a method for one-way file transmission across secret levels.

Background technique

The data transmission in the one-way mode is one-way, and the communication parties, one party is fixed as the sending end, and the other party is fixed as the receiving end. Information can only be transmitted in one direction, using a single transmission line. One-way transmission of information is the basis of serial data communication. Data is usually transmitted between two sites. According to the direction of data flow, it can be divided into three transmission modes: one-way, half-way, and full-way.

In order to protect the security of internal systems of important organizations, for example, some units have established various levels of confidential networks. However, in actual work, business systems and staff in high-security domain networks often need to transmit certain data or files to low-security domain networks, that is, one-way transmission. Data can only be transmitted one-way from high-density networks to low-density networks, and Physical isolation is required, and there is no connection or interaction in the reverse direction. Generally, it is realized through the principle of one-way transmission of light. For example, an optical code one-way transmission system can satisfy the one-way transmission from a high-density network to a second-density network.

However, in the existing unidirectional transmission technology, relatively complex transmission signal conversion equipment and supporting media are required, so we need a simple and efficient unidirectional transmission method.

Contents of the invention

In view of the above problems, the purpose of the present invention is to provide a one-way file transfer method across secret levels, which has the advantages of simplicity and high efficiency.

Above-mentioned purpose of the invention of the present invention is achieved through the following technical solutions:

A cross-class one-way file transfer method, comprising the following steps, characterized in that the data of the server in the high-density area is extracted by an RPA robot, the extracted data is encrypted, and the encrypted data is formatted. Encapsulate the data in the data carrier, and transmit the encapsulated data to the low-density area through the video stream. After receiving the data in the low-density area, the data carrier is unpacked, the data is deformatted, and the data is decrypted. The decrypted data is processed by the RPA robot. The collection is sent to the target server.

Furthermore, the transmission process of the video signal is that the source computer converts the digital signal in the computer into an analog signal through the video capture card, and then carries the one-way output through the video output port, and reaches the input interface of the video capture card of the target server, and then The video capture card converts the analog video signal into a digital signal and stores it in the target server.

Furthermore, the video output interface is a VGA analog simplex transmission mode, without a signal feedback function and mechanism.

Further, the data encoding method adopts fountain code technology.

Compared with prior art, the beneficial effect of the present invention is:

(1) The one-way transmission technology uses video signals as the transmission medium, and only requires video encoding and decoding equipment and video lines, which is simpler and more reliable;

(2) Use the fountain code technology to cooperate with its own data format and data encryption technology to realize the encoding and decoding on the basis of the original data, which is more direct and more efficient. The transmission efficiency of the one-way transmission technology of the present invention mainly depends on the encoding and decoding efficiency;

(3) Through RPA technology, complete automation and intelligence can be realized for data collection according to the user's intention;

(4) Using the latest RPA software technology, fountain code coding technology, self-owned data format optimization, and low hardware costs, it has a better cost advantage as a whole.
