Physical isolation one-way information transmission system

Abstract

The invention relates to a physical isolation one-way information transmission system, which solves the technical problem that the complete isolation is incompatible with the convenience. The system comprises an internal network access unit; an external network access unit; a laser one-way receiving unit connected to the internal network access unit; a laser one-way transmitting unit connected tothe external network access unit; an external network end file sending software installed on an external network end PC connected to the external network access unit by a network interface; and an internal network end file receiving software installed on an internal network end PC connected to the internal network access unit by the network interface. According to the above technical scheme, the problem is solved. The physical isolation one-way information transmission system can be used in an information transmission application.

Description

Technical field [0001] The invention relates to the field of information security, in particular to a physical isolation unidirectional information transmission system. Background technique [0002] With the development of modern information technology, information transmission has become a necessary part of people's work and life. For some information confidential units or key departments, information is required to be safe and reliable, and internal information must not be leaked. In these applications, strict isolation between the internal network and the external network is required. Since various technologies currently rely heavily on external Internet information, in actual work, a large amount of information needs to be imported from the external network to the internal network. The existing way is to realize this one-way information through CD copy transmission. However, in practical applications, this method of CD copying has big problems. First, it causes a lot of was...

AI Technical Summary

Problems solved by technology

But in actual application, there are big problems in this way of CD copying. First, it causes a lot of waste of CDs; It is difficult to realize the supervision of information copying, resulting in omissions in the process of information copying

Another existing method is to use the network gate technology, but the existing network gate technology only uses the information ferry method, which is still physically connected to the internal and external networks, and cannot completely achieve the physical isolation of the network, so the isolation is not complete
