Abstract

The invention relates to a safety isolation file transmission control method, in particular to a file transmission control method between taxation network safety isolation systems. A transmission control system comprises an external network isolation firewall, an external network control end, an external network transmitting end, an external network receiving end, an internal network transmitting end, an internal network receiving end, an internal network control end and an internal network isolation firewall. A computer system, a virtual machine system and the isolation firewalls are combined to achieved a relatively universal safety data transmission manner, safe and reliable bidirectional data transmission is achieved by the control method with a special safety protocol, confidentiality, completeness and non-repudiation during information transmission are achieved by safety techniques such as data encryption, digital signatures and information authentication codes, data exchanging performance is increased while safety of internal and external network systems is guaranteed, and the whole system can work reliably and stably.

Description

technical field

[0001] The invention relates to a network security isolation control method, in particular to a file transmission control method between taxation network security isolation systems. It is suitable for transferring data between networks with different confidentiality levels, and realizes the efficient transmission of files between different networks while ensuring network security. Background technique

[0002] The concept of isolation was created in order to protect a high-level security network environment, during which it experienced five generations of isolation technology changes. The first generation of isolation technology - complete isolation: This method makes the network in an information island state, achieving complete physical isolation, requiring at least two sets of networks and systems, and more importantly, the inconvenience of information exchange and the increase in cost. Maintenance and use have brought great inconvenience. The second gen...
