Description
Technical field
The present invention relates to information security field, particularly a kind of information safety devices that integrates functions as one and using method thereof.
Background technology
As everyone knows, the process of computer booting protection process or client-access remote server, only by requiring the user to input password to confirm whether its identity is legal, as long as the user can correctly input password, computer just thinks that he is a validated user usually.But in concrete application process, the static password authentication mode exists many unsafe factors, very easily causes password to reveal and causes a series of illegal logins.Simultaneously,, just can change content wherein, realize the normal startup of system, so the static password authentication mode be a kind of identification authentication mode that has potential safety hazard if hard disk is transplanted in the computer that does not have password.
Intelligent key apparatus is a kind of small hardware device that has processor and memory, and it can be connected with computer by the data communication interface of computer.Intelligent key apparatus adopts the legitimacy of PIN code identifying user identity, when carrying out authentication, intelligent key apparatus is linked to each other with computer, the user imports PIN code on computers, the correctness of automatic this PIN code of verification of intelligent key apparatus meeting, when having only the PIN code of importing as the user correct, just allow user's operative intelligence key device.Intelligent key apparatus also has the key systematic function, but and safe storage key and preset cryptographic algorithm.The intelligent key apparatus computing relevant with key be fully at the device internal operation, and intelligent key apparatus has the anti-characteristic of attacking of physics, and fail safe is high.
Because intelligent key apparatus has the characteristic of high safety, so much require the higher field of fail safe, all adopts intelligent key apparatus to carry out authentication, to guarantee the fail safe of operation.For example the computer booting protection system just often utilizes intelligent key apparatus to confirm user's identity.
However, intelligent key apparatus yet exists leak at secure context, if network hacker just can be realized illegal login under the situation of intercepting and capturing PIN code.
Dynamic password also claims disposal password (One-time Password), and it refers to user's password according to time or the continuous dynamic change of access times, and each password only uses once.The dynamic cipher verification mode is general to be adopted a kind of specialized hardware that is referred to as dynamic token (dynamic token also can be a form of software, java program as mobile phone), the password that it is built in the special cryptographic algorithm of operation generates chip, according to current time or access times generation current password and output.Certificate server adopts the identical current valid password of algorithm computation.The user is by importing dynamic token with factors such as self-defining static password, time/incidents, generate dynamic password by dynamic token in conjunction with built-in shared key, after generating dynamic password, the user transfers to identification service system by network with userspersonal information and current dynamic password in client, if the identification service system password authentification is passed through, then the user can login.Because each password that uses must be produced by dynamic token, has only validated user just to hold this hardware, as long as password authentification is passed through, system just can think that this user's identity is reliable.Because the each password that uses of user is all inequality, so, also can't utilize this password to come the identity of counterfeit validated user even the hacker has intercepted and captured password one time.The dynamic cipher verification mode has improved client user's fail safe effectively, and rapidly at home many industries of Web bank, telephone bank, online game or the like have obtained to use widely.
The dynamic password device only can realize producing the effect of password on function, function singleness for the higher computer system of security requirement, all needs dynamic password device and other safety means to combine use, and it is very loaded down with trivial details to operate.
In the prior art, intelligent key apparatus or dynamic token mainly connect by serial ports or USB interface and computer, and to realize the communication of data, range of application is restricted.A kind of dynamic password systematic function that both had is not arranged at present as yet, have the intelligent key function again, and can be by realizing the equipment of information communication between noncontact mode and the card reader.
The principle of non-contact technology mainly is an embedded antenna and microelectronic chip in device, when this device is regional near the actual induction of card reader, just can finish the primary information exchange between them, need not do any contact, just can realize the transmission of data with coupled-inductors.Because contactless technology is compared with the contact technology, has advantages such as ease for use is strong, reliability is high, easy to operate, not easy to wear, therefore just be applied to the every field of social life more and more widely.
