Abstract
The utility model relates to a misplug prevention network connecting device, which comprises a network connecting cable with a special-shaped plug and a special-shaped network interface socket. As for a network with a high security level, such as an intranet, the network connecting cable with the special-shaped plug is adopted to connect a computer and a network socket. As for a network with a low security level, such as an extranet, an ordinary network connecting cable is adopted to connect the computer and the network socket. Therefore, the network connecting cable for a specific network can only be used for being connected to a host with a specific security level, but can not be used for being connected to hosts with other security levels, thereby eliminating an accident of secret leakage caused by misconnection of two networks because of misplug of the cable.
Description
Technical field
The utility model relates to a kind of network connection device of anti-mis-insertion.
Background technology
Develop rapidly along with the Internet, computer network is divulged a secret and is on the rise, in relating computer, confidential data is lost problem, and oneself becomes a difficult problem that makes Party and government offices, army, Defence business, scientific research institution and the concentrated public services of citizen's essential information data have a headache very much.According to interrelated data, show, in security work at present, the leakage of a state or party secret that computer network and computer obliterated data cause, oneself accounts for the more than 70% of sum of divulging a secret, and is increase year after year trend.
Oneself becomes the main channel of revealing state secret computer information system, serious threat national security and interests, threaten the patented technology of enterprise and citizen's personal secrets, in the urgent need to new technology, effectively prevent that computer network from divulging a secret and computer is lost, the stolen problem of divulging a secret causing, guarantee the safety of computerized information.
According to the relevant regulations of national security system, for the generation of divulging a secret that prevents that computer from using, the major way of divulging a secret that prevents that current China takes is to adopt two computers to access respectively Inside and outside network.Intranet is the network of high safety grade, and the informational needs transmitting above holds in close confidence.Outer net is the network of lower security grade, is generally used for connecting Internet, and the information of transmitting above does not need to hold in close confidence, is also easily subject to the attack separately on the Internet and steals secret information.
Although this kind of mode can prevent that security information is leaked to the Internet from Intranet to a certain extent, but because user need to operate two computers simultaneously, and because the inside and outside netting twine plug and socket of two computers uses is identical, inside and outside netting twine wrong problem easily occurs, and the confidential information that causes inner net computer is leaked on the Internet by the netting twine of wrong.
Therefore, eliminate due to inside and outside netting twine wrong, cause the confidential information of inner net computer to be leaked to the security incident on the Internet, become safe and secret field technical problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to eliminate due to inside and outside netting twine wrong, causes the confidential information of inner net computer to be leaked to the security incident on the Internet.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A network connection device for anti-mis-insertion, comprises the network connection, the heterogeneous networks interface socket that contain special-shaped plug.
As preferably, a kind of network connection device of anti-mis-insertion, described network connection one end of containing special-shaped plug is special-shaped plug 2, and the other end is common RJ45 network interface plug 3, and described heterogeneous networks interface socket comprises special-shaped socket 1, common RJ45 network interface socket 4.
As preferably, a kind of network connection device of anti-mis-insertion, described in contain special-shaped plug network connection one end be special-shaped plug 6, the other end is special-shaped plug 7, described heterogeneous networks interface socket comprises special-shaped socket 5, heterogeneous networks interface socket 8.
For the network (Intranet) of high safety grade, use the network connection that contains special-shaped plug to connect cyber-net socket.For the network (outer net) of lower security grade, use general network connecting line to connect cyber-net socket.For the network connection of particular network, the main frame of particular safety grade can only be connected like this, and the main frame of other safe classes can not be connected.
The beneficial effects of the utility model are as follows:
The utility model passes through the computer to high safety grade network, network socket, and for connecting the network connection of above-mentioned socket, be different from the transformation of existing common RJ45 netting twine.For high safety grade network of network connecting line, the main frame of high safety grade can only be connected like this, and the main frame of other safe classes can not be connected.Thereby stopped the accident of divulging a secret causing owing to mispluging the incorrect link of two networks that netting twine causes.

Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The first execution mode has been described in the left side of Fig. 1.Comprise that one end is special-shaped plug 2, the other end is the network connection of common RJ45 network interface plug 3, for connecting special-shaped socket 1 and the common RJ45 network socket 4 of computer of the network (Intranet) of high safety grade, as shown in Fig. 1 left side.In this mode, the computer of high safety grade network network socket 1 used is special-shaped socket, and one end of network connection is special-shaped plug 2, and the other end is common RJ45 network interface plug 3.This execution mode can be used existing common RJ45 network socket, also can prevent the mispluging of computer-side simultaneously, but can not prevent mispluging in network socket side.
The second execution mode has been described in the left side of Fig. 2.One end is special-shaped plug 6, and the other end is the network connection of special-shaped plug 7, for connecting the special-shaped socket 5 of computer of the network (Intranet) of high safety grade, and the network socket of special-shaped socket 8, as shown in Fig. 2 left side.In this mode, the computer of high safety grade network network socket 5 used is special-shaped socket, and the two ends of network connection are special-shaped plug 6,7, and network socket is also special-shaped socket 8 simultaneously.This execution mode need to be used the heterogeneous networks socket different from existing general network socket, but both can prevent the mispluging of computer-side, and also can prevent from, the mispluging of network socket side, having higher security performance.
The special-shaped plug 2,6,7 relating in summary above and specification is the male (Fig. 3) of enhancement mode 9 pin S terminals.Special-shaped socket 1,5,8 is the female (Fig. 4) of enhancement mode 9 pin S terminals.
More than by the detailed description of concrete and preferred embodiment the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement etc., within all should being included in protection range of the present utility model.
