Switching system relating computer inner-external network data safety

Abstract

The invention relates to a safe exchange system for the sensitive computer data of an internal network and an external network, which is mainly characterized in that the safe exchange system includes a USB expanding bridge part, a switching control part and a data exchange area part. The USB expanding bridge part and the USB bus of the computer are mutually connected; the USB expanding bridge part and the a data exchange area part are mutually connected by a readable and writable data line; the USB expanding bridge part is connected to the switching control part by controlling the data line. The switching control part is connected to the data exchange area part by the readable and writable data line; the switching control part is connected to the power of the harddisk of the internal network and is connected to the power of the harddisk of the external network. The safe exchange system is also provided with an interface. The safe exchange system of the invention can ensure that the internal network is not infected by various viruses, prevent the information leakage and divulgence, protect the data of the internal network from damage and ensure the safe operation of the operation system.

Description

technical field [0001] The present invention relates to a component of a computer, more specifically, the present invention relates to a component related to a secret-related computer, in particular to a system for safely exchanging data between internal and external networks of a secret-related computer. In the International Patent Classification, the present invention should be classified into G06 category. Background technique [0002] As we all know, when using a confidential computer for office work, it is necessary to communicate with the outside world frequently. The confidential computer adopts a dual hard disk structure, which separates the hard disk for Internet access from the hard disk for processing important information. In the office, it is often necessary to transfer relevant files on the hard disk of the external network to the hard disk of the internal network for processing, so it is easy for various viruses in the external network to infect the internal n...
