Therefore, the utility model provides a computer network security controller through relay selectivity function, has realized the security of the secret hard disk of computer to simplify computer network security controller's structure, improved computer network safety.
Description
Technical field
This utility model relates to computer realm, particularly relates to a kind of network security controller of computer.
Background technology
Along with developing rapidly of computer technology and network technology, computer has become as people's work and life
In indispensable instrument.It addition, along with the development of the Internet, most computer has accessed network.
Thus, bring serious threat also to the information security of computer.Such as, the network information steal, information
Attack and virus disseminating etc..For the potential safety hazard preventing network from bringing, large enterprise is provided with LAN and hands over
Change planes and fire wall.But this mode is for small business or personal computer, high cost,
Cannot realize.
Therefore, network security controller of computer of the prior art, major part is by arranging multiple relay
Or double-point double-throw switch selective runs multiple hard disk, realize the network security of computer.
But, network security controller of the prior art, internal components is more, and structure is complicated.
Utility model content
This utility model embodiment provides a kind of network security controller of computer, can solve prior art
In the baroque problem of computer network controller.
The network security controller of computer of this utility model embodiment, drives including central processing unit, relay
Device, relay, secrecy hard disk, unclassified hard disk, network interface card and pci interface, this central processing unit respectively with
This relay drive, this unclassified hard disk and the electrical connection of this pci interface, this relay drives with this relay respectively
Dynamic device, this secrecy hard disk and the electrical connection of this network interface card.
It is also preferred that the left this network security controller of computer also includes security protocol processor, at this security protocol
Reason device electrically connects with this central processing unit.
It is also preferred that the left the model of the relay drive in this network security controller of computer is DS2003CM.
It is also preferred that the left the model of the relay in this network security controller of computer is RM35TF30.
The network security controller of computer that this utility model provides, the selectivity merit of the relay by arranging
Can, it is achieved that the safety of computer information security hard disk, thus simplify the knot of network security controller of computer
Structure, improves computer network security.
Accompanying drawing explanation
The computer network security structural representation that Fig. 1 provides for this utility model embodiment.
Description of reference numerals:
101-central processing unit, 102-relay drive, 103-relay, 104-secrecy hard disk, the non-guarantor of 105-
Close hard disk, 106-network interface card, 107-PCI interface.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model, the technical scheme of this utility model embodiment is carried out clear,
Complete description, it is clear that described embodiment is a part of embodiment of the present utility model rather than complete
Portion's embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creation
Property work on the premise of the every other embodiment that obtained, all should belong to the scope of this utility model protection.
The structural representation of a kind of network security controller of computer that Fig. 1 provides for this utility model embodiment one
Figure.As shown in Figure 1.
This network security controller of computer can include central processing unit 101, relay drive 102, relay
Device 103, secrecy hard disk 104, unclassified hard disk 105, network interface card 106 and pci interface 107, this centre
Reason device 101 electrically connects with this relay drive 102, unclassified hard disk 105 and pci interface 107 respectively,
This relay 103 electrically connects with described relay drive 102, secrecy hard disk 104 and network interface card 106 respectively.
Should be understood that the normally opened contact of relay 102 can be connected with network interface card 106, normally-closed contact can be with guarantor
Close hard disk 104 connects, and optionally, the normally opened contact of relay 102 can also be connected with secrecy hard disk 104,
And the normally-closed contact of relay 102 can be connected with network interface card 106.Below with the normally opened contact of relay 102
It is connected with network interface card 102, as a example by normally-closed contact is connected with secrecy hard disk 104, describes the present embodiment in detail, aobvious
So, this utility model is not limited thereto.
This network security controller of computer under init state, the coil losing electricity of relay 103, then with
The network interface card 106 that relay 103 normally opened contact connects does not works, and be connected with relay 103 normally-closed contact
Secrecy hard disk 104 can normally work.Now, permissible between secrecy hard disk 104 and central processing unit 101
Carry out data transmission.After secrecy hard disk 104 data are transmitted, and when needing to connect network, relay is driven
It is electric that dynamic device 102 can drive the coil of relay 103 to make it obtain, and relay 103 is in attracting state, its
Normally opened contact is connected and normally-closed contact disconnects, thus the network interface card 106 being connected with relay 103 normally opened contact is opened
Beginning work, and the secrecy hard disk 104 being connected with relay 103 normally-closed contact quits work.As can be seen here,
Network interface card 106 and secrecy hard disk 104 only one of which all the time can normally work, thus ensure that and need security information
Safety.It addition, unclassified hard disk 105 is connected with central processing unit 101, can ensure that it is just all the time
Often work, the most normally works with network interface card 106 unrelated.
Therefore, the network security controller of computer that the present embodiment provides, carrys out selectivity by a relay
Control the properly functioning of network interface card and secrecy hard disk, it is achieved thereby that the safety of need for confidentiality data, and
Reduce the complexity of network security controller of computer.
Preferably, in order to improve the security performance of system further, can control at this computer network security
Security protocol processor is set on device, will be connected with central processing unit 101 by this security protocol processor, from
And the encryption of data and the acceleration of firewall hardware can be realized.
Optionally, the network security controller of computer that this example provides, the model of this electric drive 102 can
To be DS2003CM.
Optionally, the network security controller of computer that this reality embodiment provides, the model of relay 103 can
Think RM35TF30.
In sum, the network security controller of computer that this utility model provides, by arranging a relay
Device so that the secrecy hard disk of computer can be out of service when networking, thus ensure that user protects
The safety of ciphertext data, simplifies the structure of network security controller of computer, reduces complexity.
Only several specific embodiments of the present utility model disclosed above, but, this utility model embodiment
Being not limited to this, the changes that any person skilled in the art can think of all should fall into guarantor of the present utility model
Protect scope.
