System and method for realizing unidirectional data transmission by using reverse gatekeeper

Abstract

The invention discloses a system and a method for realizing one-way data transmission by using a reverse gatekeeper, and the method is characterized in that at the extranet side of a reverse gatekeeper equipment module, the output end of an application client is connected to the input end of the reverse gatekeeper equipment module through an extranet reverse gatekeeper interface module; the extranet reverse gatekeeper interface module comprises an extranet user interface, a message sequence packaging module, an encryption compression module, an E file conversion module and a reverse gatekeeper load balancing module which are connected in sequence; on the intranet side of the reverse gatekeeper equipment module, the output end of the reverse gatekeeper equipment module is connected to the input end of the application program server through the intranet reverse gatekeeper interface module; and the intranet reverse gatekeeper interface module comprises a reverse gatekeeper file monitoring module, an E file analysis module, a message sequence recombination module, a decryption and decontraction module and an intranet user interface which are connected in sequence. According to the method, simple module interface calling is used, and meanwhile, the data transmission bandwidth is expanded by deploying a plurality of reverse gatekeeper devices, so that the data transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of reverse gatekeeper data transmission and security, in particular to a system and method for realizing one-way data transmission by using a reverse gatekeeper. Background technique [0002] Due to the country's increasing emphasis on electronic information security, in order to ensure information security in the production environment, when power plants transmit data to regional companies or group companies through the Internet, they generally need to use reverse gatekeepers for security isolation, and reverse gatekeepers do not allow direct TCP communication, only allows the power plant side to save the data in the E file format to the disk file of the computer outside the reverse gatekeeper, and then ferry the E file to the computer inside the reverse gatekeeper through the reverse gatekeeper, so as to realize data transmission. , which greatly guarantees the security of information transmission, but also limits n...

Problems solved by technology

[0006] The purpose of the present invention is to provide a system and method for realizing one-way data transmission using a reverse gatekeeper, so as to solve the problem of complex development, excessive restrictions on data format and transmission efficiency when performing data transmission in a network using a reverse gatekeeper. Low-level problems, the present invention provides the external network reverse gatekeeper interface module for the application program client on the external network side of the reverse gatekeeper, and provides the internal network reverse network for the application program server on the internal network side of the reverse gatekeeper. The gate interface module converts the complex reverse gatekeeper data communication into a simple module interface call. At the same time, it can expand the data transmission bandwidth and improve the data transmission efficiency by deploying multiple reverse gatekeeper devices
