Problems solved by technology

The vast majority of companies have implemented the separation of internal and external networks, the isolation of the Internet from the intranet, the production network from the office network, and the office network from the R&D network. However, after the separation of the internal and external networks, the company will face a series of new problems : The physical isolation of the network brings a lot of inconvenience to data exchange. Generally, the gatekeeper is used to realize the transmission of internal and external network files
However, the gatekeeper is generally used for exchanging business data between internal and external networks, and requires professionals to maintain it. It cannot support file exchange between people, which seriously affects the development of business.

Embodiment Construction

[0048] like figure 1 as shown, figure 1 It is a schematic flowchart of a cross-network transmission method used by an individual soldier proposed in the first embodiment of the present invention.

[0049] refer to figure 1 , a cross-network transmission method used by individual soldiers proposed in the first embodiment of the present invention is applied to include an internal network transmission unit, an isolated switching unit, and an external network transmission unit, such as figure 2As shown, the isolated switching unit is connected to the internal network transmission unit and the external network transmission unit by means of a ferry switch, and is automatically disconnected from the external network when connecting to the internal network. Similarly, when connecting to the external network Automatically disconnect from the internal network, realize the connection with the internal and external networks at any time at different times, interrupt the direct connectio...

Abstract

The invention relates to a cross-network transmission system and method used by an individual soldier. A secret key request and transmission data are sent to an isolation exchange unit through an intranet transmission unit; the isolation exchange unit generates an encryption key and a corresponding serial number and feeds back the encryption key and the corresponding serial number to the intranet transmission unit; an external network transmission unit obtains the encryption key and the corresponding serial number, and sends a data request to the isolation exchange unit according to the serial number; the isolation exchange unit sends a key verification request to the external network transmission unit based on the serial number; the external network transmission unit sends the encryption key to the isolation exchange unit; the isolation exchange unit verifies whether the encryption key sent to the intranet transmission unit is consistent with the encryption key received from the extranet transmission unit or not according to the serial number, and if yes, transmission data is sent to the extranet transmission unit; and the external network transmission unit obtains transmission data. In the invention, the cross-network transmission of the file is realized through the isolation exchange unit, and the encryption cross-network transmission between individuals is realized through the encryption key.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a cross-network transmission system and method used by individual soldiers. Background technique [0002] As the country attaches great importance to information security, information security has become an important part of national security. In accordance with the requirements of various national departments, the company has comprehensively carried out the construction of information security protection system in recent years, adopted the information security strategy of "dual network and dual machine, partition and domain, hierarchical protection, and multi-layer defense", and deployed internal and external network isolation, etc. A series of security protection measures have comprehensively improved the security protection capabilities, and successfully completed the information security protection tasks in various important periods. [0003] With the gradual deepening of th...
