Description
Technical field
The utility model relates to a kind of dynamic password equipment, relates in particular to a kind of hardware token.
Background technology
Authentication is the assurance system safety, stable operation is indispensable and a vital link.The user is when the access application system, the identity that needs at first to verify the user by certain Authentication mechanism with declared whether consistent, after the authentication success could according to user's identity and authorization database decision user whether can access system certain resource or carry out a certain operation, otherwise its visit will be refused by system.At present, adopt dynamic password equipment to carry out above-mentioned authentication usually.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.Dynamic password adopts a kind of equipment that is referred to as hardware token, and sizableness is in a flash disk, and display mode is similar to electronic watch, and its built-in power, password generate chip and display screen.Password generates the special cryptographic algorithm of chip operation, generates current password and is presented on the display screen according to current time or access times.Certificate server adopts the identical current valid password of algorithm computation.Because each password that uses must be produced by hardware token, has only validated user just to hold this hardware token, as long as password authentification is passed through, system just can think that this user's identity is reliable.And the each password that uses of user is all inequality, even the hacker has intercepted and captured password one time, also can't utilize this password to come the identity of counterfeit validated user.
The period of change of at present common hardware token dynamic password is 60 seconds, and the application scenario efficient of repeatedly inputing password at needs is very low.Owing to the interval between two passwords is longer, attacked easily.Simultaneously, common hardware token has only simple switching on and shutting down button, can't guarantee the safe in utilization of token.The password of common token changes the variation that only depends on the time, can't use in the Verification System that adopts challenge/answer-mode.Common token can only be preserved the seed data of an account number correspondence, and the user must carry a plurality of different tokens in a plurality of independently application, is not easy to use.The utility model is exactly the improvement that proposes at the above-mentioned shortcoming of common hardware token.
The utility model content
Technical problem to be solved in the utility model provides a kind of hardware token, can effectively improve the fail safe of account number cipher, and can preserve two or more seed datas, so that be applied to different application systems.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of hardware token comprises control circuit board, display screen, power supply, clock module and button; Display screen, power supply, clock module and button link to each other with control circuit board respectively; Control circuit board is used for the conserving species subdata, calculates dynamic password and dynamic password generation time, and drives display screen; Button is used to be provided with startup password, input challenge code and dynamic password; Clock module is used to produce the synchronised clock of dynamic password.
The resistance and the electric capacity that microcontroller, 32768HZ crystal are arranged on the described control circuit board and be used for built-up circuit.
Preserve two or more independently seed datas in the described control circuit board simultaneously.
Described button by the password input key that is used to import startup password and the function key that is used to import challenge code and dynamic password form.
Described password input key is a numerical key.
The dynamic password synchronised clock cycle that described clock module produces is 30 seconds.
Compared with prior art, the beneficial effects of the utility model are: adopt button that startup password is set, prevent from illegally to use token; Adopt button input challenge code and dynamic password, improve the Cipher Strength that token produces; Therefore, the utility model can effectively improve the fail safe of account number cipher.In addition, can preserve two or more independently seed datas in the control circuit board, can select to use which seed data, make a hardware token can be applied in a plurality of different application systems by button.In addition, the period of change of the dynamic password of the utility model hardware token only is 30 seconds, has improved the operating efficiency of repeatedly inputing the application scenario of password at needs greatly.
Description of drawings
Fig. 1 is the circuit structure diagram of the utility model hardware token.
Embodiment
The circuit structure of the utility model hardware token can be referring to shown in Figure 1, (for example comprise control circuit board (for example, MCU (main control unit) control board), display screen (for example, 8 LCDs), power supply, disposable button cell), clock module and button (for example, keyboard matrix).8 LCDs, button cell, clock module and keyboard matrixs are connected with the MCU control board respectively.
The resistance and the electric capacity that microcontroller, 32768HZ crystal are arranged on the control circuit board and be used for built-up circuit.Microcontroller has the function of calculating dynamic password and dynamic password generation time, driving LCD (liquid crystal) display screen and reception and conserving species subdata.Clock module is used to produce the synchronised clock of dynamic password, the dynamic password synchronised clock cycle that this clock module produces is 30 seconds, the information data that clock module will produce sends the microcontroller on the control circuit board to, the period of change of this microprocessor controls dynamic password is 30 seconds, this microcontroller can also receive and preserve simultaneously two or more independently seed datas, this seed data (also can be described as " initial key ") writes one group of data of each hardware token when being production, calculate current dynamic password with it and time two parameters.Can select to use which seed data by button, make a hardware token can be applied in a plurality of different application systems.Button is made up of password input key (this password input key is a numerical key) and function key, is used for functions such as input setting/input startup password, input challenge code and dynamic password.Password input key is used to import startup password; Function key is used to import challenge code and dynamic password, and challenge code is a password that needs before dynamic password produces, and therefore, should at first import challenge code, and then the input dynamic password.The user can enter startup password by combination button state is set, and 4 startup passwords are set.The user can also be when needed confirms by button input challenge code and dynamic password and with function key.
The utility model can be provided with the safety of startup password with the protection hardware token by increasing numeral and function button, also is used to import challenge code and dynamic password to strengthen the Cipher Strength that hardware token generates.A feature of this hardware token is to preserve two or more independently seed datas, so that be applied to different application systems.Another feature of this hardware token is that the period of change of its dynamic password only is 30 seconds, has improved the operating efficiency of repeatedly inputing the application scenario of password at needs greatly.
