The center processor is used for calculating dynamic cipher, after button triggering, the center processor obtains synchronized clock from the clock module, calculates current dynamic cipher and transmits display data to the electronic paper display module, and the electronic paper display module displays the current dynamic cipher. The clock module is used for generating synchronized clock. The utility model has a dynamic cipher token function, is convenient for carrying, has waterproof, shockproof and knock resistant performances, and reduces risks of forgetting and losing the token, the display is refreshed by button triggering, the displayed number is dynamic cipher, and the proved cipher has high strength and is not easy to decipher.
Description
Technical field:
The utility model relates to a kind of dynamic password equipment in conjunction with electronic paper technology, relates in particular to a kind of Electronic Paper smart card token.
Background technology:
The dynamic password technology be a kind of allow user cipher according to time or access times constantly change, each password can only expendable technology.It adopts a kind of specialized hardware that is called dynamic token, and built-in power, password generate chip and display screen, and 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.When using, the user only the current password input client computer that shows on the dynamic token can need be realized authentication.Because each password that uses must be produced by dynamic token, has only validated user just to hold this hardware, as long as just can think that by password authentification 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.
Electronic Paper (ePaper) is the electronic display unit of a new generation, and technical characterstic is exactly the contrast superelevation, shows that than plain paper contrast is also high, so also no problem under strong sunlight.Just electricity consumption when power saving, clear screen, outage keep showing.Ultra-thin, the thinnest can accomplish 0.1mm, and similar with paper, bending fold has good pliability arbitrarily.
Token mostly is hardware token at present, is independent of bank card and exists, and the minority token is an Electronic Paper smart card token, and promptly smart card has generation random cipher function.Hardware token dynamic password period of change was generally 60 seconds, and volume is big, carries inconvenience, and did not generally possess waterproof shatter-resistant antihunt action.And the binding procedure of hardware token and bank card is loaded down with trivial details.Electronic Paper smart card token mostly is the event mode token, and the event mode token is that button triggers, and the password of triggering for generating has very big risk to a certain extent as not using the meeting continuously effective.
The utility model content:
The utility model technical issues that need to address provide a kind of Electronic Paper smart card token.This device adopts Electronic Paper as display screen, and button refreshes the current dynamic password of demonstration, and using the term of validity is 3 years, and the outside has the international standard magnetic stripe, can provide read-write for operators such as banks.
The technical scheme that the utility model need solve: a kind of Electronic Paper smart card token, can realize the smart card token of dynamic password type.This product comprises that the outside is provided with the intelligent card body of magnetic stripe, and card body inside is embedded with central processing unit, and realizes Electronic Paper display module, clock module, battery and the button that circuit is connected with this central processing unit by flexible PCB respectively.Central processing unit is used to calculate dynamic password, and button triggers the back central processing unit and obtains to calculate the present dynamic password behind the synchronous clock from clock module, sends video data to the Electronic Paper display module, and the Electronic Paper display module shows current dynamic password.Clock module is used to produce synchronous clock.
The period of change of described dynamic password is 60 seconds.
The outside magnetic stripe of described smart card is the international standard magnetic stripe;
Described flexible PCB is flexible ultrathin circuit board;
Described central processing unit is the super low-power consumption microcontroller, and internal storage is used for the conserving species subdata, and is not readable, and the power down data are promptly lost.Have the serial port that is used for obtaining seed data simultaneously from computing machine, and the communication interface of may command Electronic Paper display module show state;
Described clock module can produce the clock with server sync;
Described Electronic Paper display module comprises electronic-paper display screen and driving;
Described button is a pressure transducer formula button.
Described battery is a ultra-thin lithium cell.
The beneficial effects of the utility model are, the Electronic Paper smart card has dynamic password token function concurrently, and easy to carry and water, shock shatter-resistant reduces the risk of forgeing token and losing, button triggers and refreshes display screen, display digit is a dynamic password, and the Cipher Strength height that provides is difficult for cracking, this smart card is throughout one's life without battery in addition, big and the smart card operator length of service of battery term of life, token and smart card need not binding, have improved ease for use greatly.The generation password is a dynamic password, and Cipher Strength height, period of change are 60 seconds.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is an Electronic Paper smart card token structured flowchart described in the utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, Electronic Paper smart card token described in the utility model comprises central processing unit (for example microcontroller), and with its Electronic Paper display module that is connected respectively (six or 8 electronic-paper display screens, Electronic Paper is special-purpose to be driven), power supply (for example ultra-thin lithium cell), clock module (32.768K crystal and RTC (real-time timepiece chip)), button (for example pressure transducer).Above-mentioned module realizes that by flexible ultrathin flexible PCB circuit is connected with parts.
This Electronic Paper smart card token after central processing unit is triggered by button, obtains the current time and calculates the generation dynamic password from clock module in use, sends video data to the Electronic Paper display module, and Electronic Paper refreshes the demonstration dynamic password.Central processing unit enters stop mode.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
