Abstract
The utility model discloses USB (universal serial bus)-interface-based safety equipment, which comprises a safety equipment host, a USB controller, a USB interface, a memory and a fingerprint acquisition board, wherein the safety equipment host is connected with the USB controller through a PCI (peripheral component interconnect) bus; the USB controller is connected with the USB interface through an over-voltage protection circuit; the memory is connected with the safety equipment host through an internal bus; the fingerprint acquisition board is connected with the safety equipment host through a fingerprint identification circuit; the fingerprint acquisition board and the USB interface are arranged on a case of the safety equipment; the fingerprint acquisition board is adjacent to the USB interface. According to the USB-interface-based safety equipment, the safety of data in the safety equipment can be effectively ensured; due to the arrangement of the over-voltage protection circuit, external USB equipment is prevented from being damaged by overvoltage of a USB interconnect signal channel; the service conditions of the external USB equipment can be displayed through an indicator lamp, so that a user can be prevented from forgetting to unplug the external USB equipment.
Description
Technical field
The utility model relates to a kind of USB interface-based safety equipment.
Background technology
Network security refers to that the data in hardware, software and the system thereof of network system are protected, and not because of accidentally or malice former thereby wreck, change, reveal, system is reliably normally operation continuously, and network service does not interrupt.Information Communication safety on network, the safety of Information Communication consequence, comprises information filtering etc., it lays particular emphasis on and prevents and control the consequence after illegal, harmful information is propagated, and avoids in common network the information freely transmitted in a large number out of control.The secure side of the information content on network overweights confidentiality, the authenticity and integrity of protection information; avoid that assailant utilizes that the security breaches of system are eavesdropped, pretended to be, swindle etc. impairs the behavior of validated user, is protection user's interests and privacy in essence.Network Security Device mainly comprises physical security, security of system, fire wall, encryption, safety estimation system, intruding detection system, Anti-Virus, data backup system and safety management system etc.Here the safety equipment that mentioned are applicable to fields such as fire wall, VPN (virtual private network) (VPN), viral detection, information filtering, safe route, intrusion detecting and protection (IDS/IPS), network security storages.Information security manufacturer can directly utilize Network Security Device, according to the business demand of oneself, on example, modifies, to shorten product development cycle, to develop the Network Security Device with own characteristic.
Integrated high performance network safety platform solution, comprises processor, DDR, SDRAM and Flash storer on hardware in Network Security Device housing, and integrated level is high.At present, some safety equipment are USB interface-based, and this class safety equipment connected mode is simple, handled easily.But traditional USB interface-based safety equipment also have the following disadvantages: (1) security is not high, anyly have can using per capita of safety equipment, the data in safety equipment can not get due protection; (2) in the time of the overtension of the interconnected signalling channel of USB, traditional safety equipment do not have over-voltage protecting function.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of safe USB interface-based safety equipment are provided; the interconnected signalling channel of USB has over-voltage protecting function; avoid damaging external USB device because of overtension; USB device is set and uses indicating device, the user of USB safety equipment easy to use checks the service condition of equipment.
The purpose of this utility model is achieved through the following technical solutions: USB interface-based safety equipment; it comprises safety equipment main frame, USB controller, USB interface, storer and fingerprint collecting plate; safety equipment main frame is by pci bus and USB controller; USB controller is connected with USB interface by overvoltage crowbar; storer is connected by internal bus with safety equipment main frame, and fingerprint collecting plate is connected with safety equipment main frame by fingerprint recognition circuit.
Described fingerprint collecting plate and USB interface are all arranged on the cabinet of safety equipment, the adjacent setting of fingerprint collecting plate and USB interface.
The utility model also comprises pilot lamp, and pilot lamp is electrically connected with safety equipment main frame.
The beneficial effects of the utility model are:
1) fingerprint collecting plate is set, the adjacent setting of fingerprint collecting plate and USB interface, the position of fingerprint collecting plate is outstanding, be convenient to search, and only have by the designated person of fingerprint recognition and could use safety equipment, effective guarantee data security;
2) in the interconnected signalling channel of USB, overvoltage crowbar is set, has ensured the interconnected signalling channel safety of USB, avoid damaging external USB device because of the interconnected signalling channel overtension of USB;
3) service condition of circumscribed USB equipment can show by pilot lamp, and the bright expression of lamp is being used circumscribed USB equipment, avoids forgetting that pulling up circumscribed USB equipment causes loss of data.
Brief description of the drawings
Fig. 1 is the utility model structural representation block diagram.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1; USB interface-based safety equipment; it comprises safety equipment main frame, USB controller, USB interface, storer and fingerprint collecting plate; safety equipment main frame is by pci bus and USB controller; USB controller is connected with USB interface by overvoltage crowbar; storer is connected by internal bus with safety equipment main frame, and fingerprint collecting plate is connected with safety equipment main frame by fingerprint recognition circuit.
Described fingerprint collecting plate and USB interface are all arranged on the cabinet of safety equipment, the adjacent setting of fingerprint collecting plate and USB interface.
The utility model also comprises pilot lamp, and pilot lamp is electrically connected with safety equipment main frame.
The above is only preferred implementation of the present utility model, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, amendment and environment, and can, in contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
