Physical isolation information exchange method

Abstract

The invention provides a physical isolation information exchange method. The method comprises the following steps: sending information acquisition, information compiling, information displaying, idle judgment, information capturing and information decompiling. The information capturing and transformation are accomplished by use of the machine vision recognition and the machine judgment technology, thereby realizing the information capturing and transferring crossing the physical isolation and solving the key difficult point of the communication under the physical isolation. By use of the method provided by the invention, the bidirectional flow capacity of the information is maintained, before entering the information capturing, the high-level encryption and the plaintext-ciphertext shuffling are arranged on the information, so that the leakage possibility of the information when flowing in the information capturing is eliminated. The physical isolation information exchange method provided by the invention breaks through the communication bottleneck of the physical isolation, and is extensively applied to the security communication between a private network and a public network.

Description

technical field [0001] The invention relates to a method for exchanging information between physically isolated systems, in particular to a method for exchanging information between physically isolated systems. Background technique [0002] With the rapid development of computer information construction and network technology, the demand for cross-network segment access and data exchange is increasing day by day, which poses a big challenge to communication between physical isolation and cross-network segments. In many industries, such The demand has even become the bottleneck of the development of informatization construction. However, in fields that require high information security, such as confidentiality and security, physical isolation of network segments is currently the lowest-cost and most effective security method. Therefore, how to realize information communication under physical isolation is a solution to this growing The key to communication needs. [0003] At...

Problems solved by technology

[0003] At present, the commonly used methods of isolation and transmission between internal and external networks mainly use ferry, one-way transmission, barcode / QR code and other methods. These methods generally have limitations and cannot truly achieve physical isolation or data transmission in the true sense.

[0004] 1. The operation of the ferry method is cumbersome and requires a lot of labor costs and transit storage and processing equipment to complete. Both the cost and the operating threshold are not very practical. Moreover, the data capacity of a ferry is limited, and real-time data transmission and update cannot be realized, which lacks practical significance ;

[0005] 2. The one-way transmission method adopts the method of temporary isolation, and interacts through single-ended contact, which cannot achieve complete physical isolation, and also has no practical significance;

[0006] 3. The barcode / QR code method is a newly added cross-isolation communication method along with computer graphic recognition. However, due to the limited information capacity that the barcode / QR code can express, and it is limited to text information transmission, for graphics Transmission is powerless; at the same time, because the barcode / QR code has high requirements on image clarity, it is prone to unrecognizable problems when the image clarity is insufficient; on the other hand, the two-dimensional code technology needs readability And the interpretability is very high, and the compiled content is basically fixed, which makes it impossible to make random encryption according to the length of the ciphertext. At the same time, the two-dimensional code technology cannot be applied to the continuous transmission of sub-packages with a large amount of data transmission
