Customized protocol communication system and customized protocol communication method of mixed data in isolated environment between internal network and external network

Abstract

The invention discloses a customized protocol communication system and a customized protocol communication method of mixed data in an isolated environment between an internal network and an external network. The customized protocol communication system comprises the components of a frontend device which comprises an external network software management module, a frontend management module, a frontend data receiving module, a frontend safety authentication module, a frontend data buffer module and a frontend data transmission module; a backend device which is configured in a manner of corresponding with the frontend device; and a network gate module. The customized protocol communication method comprises the steps of assigning a token for the software management module; integrating to-be-transmitted data based on a web service manner and outputting the integrated data to a frontend data receiving module and a backend data receiving module; verifying the token by the data receiving modules and transferring the to-be-transmitted data to the data transmission module through the network gate module; and receiving the to-be-transmitted data by the data transmission module and transmitting the to-be-transmitted data to the software management module. Through an information mechanism issuing / customizing mode, the customized protocol communication system and the customized protocol communication method have advantages of controlling data exchange between software in real time, improving mastering capability of a user to data exchange, and reducing operation difficulty in controlling data exchange.

Description

technical field [0001] The invention relates to a customized protocol communication system and method for mixed data in an isolated environment of internal and external networks, and belongs to the field of computer communication. Background technique [0002] Due to the need for confidentiality, there are some environments that need to be isolated from the internal and external networks. However, what is different from the previous era is that the receiving object of data is no longer a simple storage, but a lot of software. Due to the nature of these software, sending and receiving There are many types of data accepted. At present, in the isolation environment where the internal and external networks are disconnected from the TCP / IP network connection, the main methods for the application software to realize data exchange between the internal and external networks are file exchange, database exchange, audio and video data exchange, and Socks application proxy. File exchan...

Problems solved by technology

The above four data exchange methods all lack the exchange requirements of application software for semi-structured data types, including the exchange of mixed types of data such as database records, files, pictures, XML, audio and video clips customized by application software. High-performance data transmission, as well as application software legality verification for sending and receiving data on internal and external networks
