Description
Technical field
The utility model relates to a kind of lockset with USB interface, and it is the important component part of carrying out the gate control system of identification by digital certificate.
Background technology
Present gate control system is divided into three ingredients, feature carrier, reading device and locking mechanism three parts.Gate control system at first must confirm whether have authority to pass through to determine it to the personnel's that come in and go out identity as the system of a kind of control and managerial personnel's discrepancy.This just need give the sign of come in and go out personnel identity and authority by a kind of method, and this sign is exactly the feature carrier.The feature carrier can be divided into biological characteristic and abiotic feature again.Biological characteristic comprises fingerprint, iris and face shape etc.Abiotic feature comprises magnetic card, IC-card, photoelectric card, radio-frequency card or the like.
Reading device is the equipment that carries out message exchange with the feature carrier, and it reads the information of holder's identity and authority by rights from the feature carrier, discerns holder's identity and the legitimacy of the request of coming in and going out with this.The reading device of biological characteristic has fingerprint recognition system, iris authentication system, face shape recognition system etc., and the reading device of abiotic feature has all kinds of reader devices.
Locking mechanism, gate control system have only had locking mechanism that practicality is just arranged.Confirmed that when reading device after holder's the identity and authority, locking mechanism can make legal person come in and go out swimmingly, and refused illegal person's request.Locking mechanism can be an electromagnetic lock, also can be mechanical lock.
Present most popular feature carrier has key and IC-card.Using the mechanical lock of key is the most original gate control system, very easy to use effective, but the shortcoming of himself is arranged.It can't write down the time that the holder comes in and goes out, and also can't allow or restriction holder's discrepancy according to certain conditions, does not for example allow the holder to come in and go out etc. in festivals or holidays.
Have unique sequence number that manufacturer sets in the IC-card, usually sequence number that will a certain IC-card on the host computer of access control system is associated with some specific holders, and determines the condition of holder's discrepancy by the power of computer software.The holder gives IC-card card reader in use and reads that (contact card is normally swiped the card or plug-in card, non-contact card then is then to be near card reader with IC-card), card reader is then passed through transmission line with the sequence number of IC-card, be transported to main control system, whether main control system mates sequence number and holder, and allow the holder come in and go out according to predefined discrepancy conditional decision.
Digital certificate is a kind of brand-new feature carrier, and it is the identity identification that is based upon on the asymmetrical encryption algorithm basis.The basis of asymmetrical encryption algorithm is a pair of PKI and private key, they are to provide to the holder after assert process by the ca authentication center with public credibility through strict identity, wherein private key is preserved by the holder, (providing under the situation that private key is used for digital signature) is provided after providing at the ca authentication center, and PKI is then by the publicity on the net of ca authentication center.PKI and private key all can be encrypted information, and inverse operation each other.In the process that authenticates, main control system can provide a segment information to the holder, require the holder to this information with encrypted private key.Obtaining after the information of encrypted private key, main control system can be to ca authentication center inquiry holder's PKI, and with PKI the information of encrypting is decrypted, and the information after will deciphering and raw information compares, if consistent then can assert holder's identity.
The carrier of digital certificate, the carrier of private key just, commonly used have CD and USB Key or the like.Storing private key with CD all has a fatal weakness, is exactly that carrier itself can not carry out computations, and private key must be read out from carrier, and carries out computations in computer, is easy to cause private key to divulge a secret like this.Best carrier is USBKey at present.The profile of USB Key is just as a USB flash disk, and its inside also has computing chip except certain storage space.The work that the utilization private key is encrypted is all finished in USB Key inside, and private key can not divulged a secret.
IC-card is compared with digital certificate, has the characteristics of not general and easy forgery.Unique sequence number of IC-card is that manufacturer oneself works out, and does not have unified standard, causes the IC-card of different vendor can't be general.IC-card and holder's coupling also just realizes on main control system, has broken away from main control system, and holder's identity just can't obtain assert.In addition, because sequence number is without any cryptographic means, anyone can obtain sequence number by card reader, and forges IC-card by technological means, or cheats main control system in communication process, makes it to think that reading device read relevant sequence number.IC-card is forged in communication process easily just, and it can not become the authentication instrument in the online transaction.
Along with popularizing of internet, the life of networking begins to become everyone life style, and is wherein important no more than Web bank.Because the singularity of Web bank, many banks all require the client to use digital certificate to prove the identity of oneself when the client carries out megadeal.Begin in the society now to accept and use the people of digital certificate more and more.When digital certificate spreads to certain degree, in gate control system, will seem unnecessary as the IC-card of the feature carrier of simple and inexpensive.As long as the main control system of gate control system can keep online, carry out authentication by the digital certificate among the USB Key and just become possibility.And all permanent online should be able to the realization in the near future of all computers.Such gate control system has been arranged, and people will no longer need to be with many keys, as long as an effective digital certificate is arranged, and it is loaded among the USB Key goes, just can realize that one the tunnel is logical.
Summary of the invention
Because the above-mentioned defective of prior art, the purpose of this utility model is to provide a kind of lockset that allows the band USB interface that lockset can read the carrier USB Key of digital certificate.
For achieving the above object, the lockset of band USB interface of the present utility model comprises: a locking mechanism; Be used to trigger the control circuit that described locking mechanism is finished the action of open and close lock; Also comprise a USB interface that can be connected with USB Key communication, described USB interface is electrically connected with described control circuit by usb circuit, is connected with communication between described USBKey to realize described control circuit; Described control circuit is connected with the communication of described USB Key by described USB interface obtains the digital certificate that is loaded among the described USB Key, simultaneously directly verify digital certificate among the described USB Key again by the internet communication, after finishing checking, described control circuit triggers the action that described locking mechanism is realized the open and close lock.
Further, described locking mechanism is realized by described Electrically operated gate magnetic or the control of described electromagnetic clutch circuit by being electrically connected Electrically operated gate magnetic or electromagnetic clutch circuit.
The utility model has been owing to connected a USB interface in existing lockset, by this USB interface, make the control circuit of lockset can realize and extraneous USB Key between communication connect.The control circuit of lockset is by reading the digital certificate among the extraneous USB Key, verify holder's identity, thereby utilize safety, the convenient feature of digital certificate, make the lockset of band USB interface of the present utility model can realize that one the tunnel is logical, greatly improve convenience and the versatility used, and had good safe reliability.
