It is identical as Intranet；Software mainly carries out ferry-boat control to data, controls the open and close of data channel, in conjunction with physics original part,
Change communication mode, interrupts and be directly connected to outside Intranet, using data buffer zone as the terminal for exchanging data.
Preferably, the outer net processing unit is visited with outer net equipment direct communication and to the communication data of outer net equipment
Ask control, outer net processing unit is connect by file memory with data exchange unit.
Preferably, the data exchange unit includes banister server and isolation firewall, is situated between based on one-way transmission physics
Matter forms independent data isolation region, and carries out independent access control, is made of multiple isolation firewalls.
Preferably, the data exchange unit is responsible for data from uplink isolation firewall to outer net processing unit and downlink
The one-way transmission that firewall arrives Intranet processing unit is isolated, the banister server forms the data buffering being isolated in firewall
Area is responsible for the data that buffering uplink isolation firewall transmission comes, and banister server is responsible for the control that accesses to data, and refusal is not
Authorized request or response, intranet and extranet form boundary isolation, data exchange state.
Preferably, the disengaging of configuration data is regular in the banister server, and such as A-> B, the end A is by data with storage medium
Form is transferred to banister, and banister filtering separates " clear data " and stored afterwards to buffer area, and the data in buffer area are in the form of queue
B end data interface is accessed to be sent to the end B, while native file being deleted, and the end B is disappeared by uplink short message channel with short
The form of breath informs the end A server.
Preferably, the overall process of configuration data is one-way transmission in the banister server, and the end A can not request the end B number
According to B end data can not also be sent to the end A.
Preferably, it needs to carry out login authentication first in the outer net equipment, after authenticating successfully, acquisition needs to send data
Path, send thread and constantly read queue to be sent and send target to be sent to outer net processing unit.
Compared with prior art, the beneficial effects of the present invention are: the present invention is ensureing internal proprietary network data safety
On the basis of, it solves the intercommunication demand for realizing data, realizes and be not connected to forever outside Intranet, one-way data transfer has been evaded mutually
Malicious attack of networking influences the data safety of Intranet, while being realized by uplink short message channel and being interacted with downlink data.
Detailed description of the invention
Fig. 1 is the principle of the present invention flow chart.
Specific embodiment
In order to make implement technical means of the invention, creation characteristic, reach purpose and effect is easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
As shown in Figure 1,
A kind of network data security management-control method based on one-way transmission, including outer net processing unit, data exchange unit
With Intranet processing unit, outer net processing unit is unidirectionally connect by data exchange unit with Intranet processing unit, at the outer net
It manages unit outer end and is equipped with outer network interface connection outer net equipment, Intranet processing unit is equipped with interior network interface and connects Intranet equipment；Intranet
Processing unit is mainly responsible for the connection with Intranet, detects to being filtered property of data, separates " clear data " and stores to buffer area,
Data exchange is waited to prepare；Outer net processing unit function is identical as Intranet；Software mainly carries out ferry-boat control to data, controls number
According to the open and close in channel, interrupts and be directly connected to outside Intranet to change communication mode in conjunction with physics original part, it is slow with data
Rush terminal of the area as exchange data.
It the outer net processing unit and outer net equipment direct communication and accesses control to the communication data of outer net equipment,
Outer net processing unit is connect by file memory with data exchange unit.
The data exchange unit includes banister server and isolation firewall, is formed solely based on one-way transmission physical medium
Vertical data isolation region, and independent access control is carried out, it is made of multiple isolation firewalls.
It is anti-from uplink isolation firewall to outer net processing unit and downlink isolation that the data exchange unit is responsible for data
For wall with flues to the one-way transmission of Intranet processing unit, the banister server forms the data buffer zone in isolation firewall, responsible
The data that uplink isolation firewall transmission comes are buffered, banister server is responsible for the control that accesses to data, and refusal is without permission
Request or response, intranet and extranet formed boundary isolation, data exchange state.
The disengaging rule of configuration data in the banister server, such as A-> B, the end A passes data in the form of storage medium
It is handed to banister, banister filtering separates " clear data " and stored afterwards to buffer area, and the data in buffer area access the end B in the form of queue
Data-interface deletes native file to be sent to the end B, and the end B passes through uplink short message channel, in the form of short message
Inform the end A server.
The overall process of configuration data is one-way transmission in the banister server, and the end A can not request B end data, the end B number
According to can not also send to the end A.
It needs to carry out login authentication first in the outer net equipment, after authenticating successfully, obtains the path for needing to send data,
It sends thread and constantly reads queue transmission to be sent target to be sent to outer net processing unit.
