Information exchange system with safety isolation

Abstract

The invention discloses an information exchange system with safety isolation, relating to the field of information safety. Real-time communication of an internal network and an external network cannot be considered simultaneously, so that the conventional information exchange system has poor convenience and security. The information exchange system with safety isolation solves the above problem. The system comprises an inner end machine and an outer end machine which are each provided with a protocol stripping module. The inner end machine and the outer end machine establish a communication connection through a data migration control unit. The data migration control unit is provided with a transmission isolation module. Due to the protocol stripping module, a network protocol of one party cannot extend to an opposite party. All previous application layer information is stripped off from the protocol stripping module and is restored to application layer information. The stripped data is transmitted between the inner end machine and the outer end machine through the data migration control unit. The transmission isolation module guarantees information transmission and simultaneously prevents one end machine from attacking the other end machine. While the internal network and external network are isolated effectively, safe and controlled data exchange between the internal network and the external network is realized.

Description

technical field [0001] The invention relates to the field of information security, in particular to an information exchange system with safety isolation that can simultaneously take into account the convenience and safety of real-time communication between internal and external networks. Background technique [0002] Security isolation technology refers to the software and hardware technology that realizes information security of network isolation when information exchange is required. With the development of security isolation requirements for e-government construction, my country's isolation technology has developed rapidly in recent years, and has gone through the following processes: [0003] 1. Multiple sets of network technologies: In the early days, there was no suitable equipment available. Some organizations achieved isolation by establishing two sets of completely independent networks. One set can be connected to the outside world, and the other set is completely c...

AI Technical Summary

Problems solved by technology

Traditional gatekeeper technology can solve the needs of information exchange and isolation to a certain extent, but it still cannot fully meet the security requirements of e-government construction in terms of security function realization and system performance

[0006] The problem with the above-mentioned isolation technology is that it cannot take into account the convenience and security of real-time communication between internal and external networks at the same time, and it is more troublesome to use.
