Embodiment

A kind of dynamic cipher device based on Electronic Paper as shown in Figure 1, Figure 2 and Figure 3, is mainly made up of electronic paper screen module, cryptosecurity module, crystal oscillating circuit module, microprocessing unit module and battery module; The output of microprocessing unit module connects electronic paper screen module, and its input is connected to crystal oscillating circuit module, battery module and cryptosecurity module, and the input of cryptosecurity module is also connected with the output of crystal oscillating circuit module and battery module.

Wherein also be provided with identity identification information module and password generating algorithm module in cryptosecurity module.Microprocessing unit module has also been arranged in parallel memory module and automatic update module.Data conversion module and format library module is also provided with in microprocessing unit module.

Based on an implementation method for the dynamic cipher device of Electronic Paper, comprise the following steps:

Step 1: user by the dynamic cipher device based on Electronic Paper near cryptosecurity module;

Step 2: cryptosecurity module is waken up, inner identity identification information module will carry out information identification to identity, by forming new password after password generating algorithm module arithmetic and passing to microprocessor unit module;

Step 3: after microprocessor unit module receives the triggering signal of cryptosecurity module, wakes the new password received from cryptosecurity module up;

Step 4: microprocessing unit module converts the form of applicable screen output to new password, is transferred to screen and redraw;

Step 5: microprocessor unit module enters resting state.

As shown in Figure 1, microprocessor unit module is the core processing unit of dynamic cipher device, and crystal oscillating circuit module provides fundamental frequency for it, and battery module provides electric energy for it, microprocessor unit module and electronic paper screen model calling, control the refreshing display of electronic paper screen.The another port of microprocessor and cryptosecurity model calling.The algorithm of dynamic password is stored in cryptosecurity module.Cryptosecurity module provides power supply by battery module, and relies on the fundamental frequency of crystal oscillating circuit module in the inner rise time.Cryptosecurity module also stores identity identification information and the password generating algorithm of this scrambler.The time that this cryptosecurity module generates according to inside and identity identification information are by after the computing of password generating algorithm, form new password, microprocessor unit is exported to by port, password is converted to the form that screen can show by microprocessor unit module, outputs to electronic paper screen module and shows.Because electronic paper screen module only just needs power consumption when needs redraw, microprocessor unit module can be in the state of dormancy at ordinary times, only when cryptosecurity module has new output according to its algorithm just by port wake-up.

As shown in Figure 2, identity identification information module and password generating algorithm module is also provided with in cryptosecurity module, the effect of identity identification information module is a kind of identification to the dynamic cipher device based on Electronic Paper, guarantee the correct transmission of information, password generating algorithm module be to identification after information and time of generation carry out computing and form new password.

As shown in Figure 3, microprocessing unit module has also been arranged in parallel memory module and automatic update module.Data conversion module and format library module is also provided with in microprocessing unit module.Memory module can produce of short duration memory time, in case user finds former password to the password formed in the time of one end; Automatic update module is that after a period of time, microprocessing unit module can delete storage password in the past automatically, ensures inner storage area, carries out the storage of the password of next group; Format library module refers in cryptosecurity module the file format that there is various screen and can show, and can facilitate the conversion of variety classes file; Data conversion module is a kind of format conversion in order to carry out the file being not suitable for screen display, and the file changed can be shown on screen.

As shown in Figure 4, embodiment one: in order to save power consumption, the utility model all have employed the mode of down trigger in design of hardware and software, namely only when cryptosecurity module has new password to generate output time, just wake-up microprocessor unit module, microprocessor unit module is all in sleep state at ordinary times.The power consumption of whole like this circuit is extremely low.After microprocessor receives the triggering signal of cryptosecurity module, wake up and start to receive the new password from cryptosecurity module.Then microprocessor unit module converts code data to the form of applicable screen output, sends to screen, and refreshes.After completing, microprocessor unit module reenters resting state.In running order at ordinary times in whole like this circuit only have cryptosecurity module.

Embodiment two: in order to save power consumption further, cryptosecurity module also can be in resting state at ordinary times, only counts/timing to crystal oscillating circuit, just only when timing time then wakes generation new password up.So also power consumption can be saved.In addition, the mode of regeneration password when also can be waken up by external key.Such mode power saving more than counting/timing.The password that timing produces after all is not used in capital.Only have user to need to access to your password, be just necessary to generate new password.

Although the foregoing describe embodiment of the present utility model; but those skilled in the art are to be understood that; these only illustrate; various changes or modifications can be made to present embodiment; and not deviating from principle of the present utility model and essence, protection range of the present utility model is only defined by the appended claims.
