Abstract
The invention discloses a subaudio electronic cipherer and a dynamic password generation method thereof. The subaudio electronic cipherer comprises a subaudio receiver, a subaudio processor, an electronic cipherer main chip and a display. The subaudio receiver receives a subaudio signal additionally attached to an audio signal. The subaudio processor carries out filtering and shaping processing on the received subaudio signal. The electronic cipherer main chip converts the processed subaudio signal into digital subaudio data and generates a challenge-type dynamic password based on user transaction information in the digital subaudio data. The display displays the generated dynamic password. By using the subaudio electronic cipherer and the dynamic password generation method thereof of the invention, lengthy user transaction information does not need to be input on the electronic cipherer with a limited space and a subaudio signal input mode is used to increase information security.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
First, please refer to Fig. 1, Fig. 1 is the block diagram of a kind of infrasonic frequency electronic cipher device of the present invention, described infrasonic frequency electronic cipher device 1 comprises infrasonic frequency receiver 11, infrasonic frequency processor 12, electronic cipher device master chip 13 and display 14, described infrasonic frequency receiver 11 receives the voice signal that outside network device 2 is play, and infrasonic frequency signal is separated from audio signal, described voice signal comprises audio signal and is attached to the infrasonic frequency signal in described audio signal, described infrasonic frequency processor 12 connects described infrasonic frequency receiver 11, described infrasonic frequency signal is carried out to filtering and Shape correction, obtain and export the infrasonic frequency signal after processing, described electronic cipher device master chip 13 connects described infrasonic frequency processor 12, receive the infrasonic frequency signal after described processing, infrasonic frequency signal after described processing is converted to digital infrasonic frequency data to obtain the customer transaction information in described digital infrasonic frequency data, challenging value using described customer transaction information as challenge type dynamic password participates in computing to generate dynamic password, described display 14 connects described electronic cipher device master chip 13 to show the dynamic password generating, for user, use and be input in described outside network device 2.Wherein, described outside network device 2 is connecting Internet the electronic equipment with audio playing apparatus, the input unit of described outside network device 2 receives the customer transaction information of user's input, the processor of described outside network device 2 is based on described customer transaction Information generation numeral infrasonic frequency data, described digital infrasonic frequency data are carried out to digital-to-analogue conversion to generate infrasonic frequency signal, the infrasonic frequency signal of generation is attached in audio signal to obtain voice signal, and described audio playing apparatus is play the voice signal generating; The dynamic password that described outside network device 2 shows user dynamic password according to the display 14 of described infrasonic frequency electronic cipher device 1 is inputted sends to certificate server place by the Internet and authenticates.Wherein, described Transaction Information comprises dealing money and transaction account number, and described outside network device 2 is desktop computer, notebook, panel computer, smart mobile phone or personal digital assistant PDA, and the frequency of described infrasonic frequency signal is 67Hz to 250.3Hz.
In addition, dynamic password, as one of safest identity identifying technology, is applied by increasing industry at present.Because he is easy to use, and platform-independent, development along with mobile Internet, dynamic password technology has become the main flow of identity identifying technology, be widely used in the fields such as enterprise, network game, finance, the enterprise that is engaged in the relevant research and development of dynamic password both at home and abroad and produces is also more and more, it is advantageous that and the quick seamless interoperability of miscellaneous service system, the command dynamic password identification authenticating software systems of its complete independent research are stable, efficient, support multiple certification mode, and its solution can be served different scales enterprise.Dynamic password technology is mainly divided two kinds: synchronous password technology, asynchronous password technology (challenge-response mode), synchronous password technology is wherein divided into again time synchronized password and event synchronization password.Time synchronized based on token and server, generates consistent dynamic password by computing, the token based on time synchronized, and general turnover rate is 60 seconds, within every 60 seconds, produces a new password.Token based on event synchronization, its principle is as input by a certain specific event order and identical seed, in algorithm, calculate consistent password, its computing mechanism has determined that its whole workflow is irrelevant with clock, be not subject to the impact of clock, life period pulse crystal oscillator not in token, but due to the consistency of its algorithm, its password is known in advance.For asynchronous token, owing to there is no to carry out synchronous condition except identical algorithm between token and server, therefore can effectively solve the problem of token step-out, reduce the impact on application, increased greatly the reliability of system simultaneously.The shortcoming that asynchronous password is used is mainly in use, user needs the step of many input challenging values, by challenging value, generate the dynamic password of challenge type, the dynamic password that generates challenge type according to challenging value equally at certificate server end is to carry out the checking of dynamic password, for operating personnel, increased complexity, therefore in when application, by according to the sensitivity of user's application with the degree that requires of safety is selected to the generating mode of password.
In addition, infrasonic frequency is CTCSS(Continuous Tone Controlled Squelch System), continuous speech is controlled squelch system, is a kind of technology of transmitting together in audio signal that the frequency lower than audio frequency (67Hz-250.3Hz) is attached to.Because its frequency range is below standard audio, therefore be called infrasonic frequency.For the intercom with infrasonic frequency pattern, when intercom carries out after intermediate frequency demodulation to received signal, infrasonic frequency signal after filtering, shaping, be input in CPU, whether the CTCSS frequency of setting with the machine compares, thereby determine to open quiet.Therefore, infrasonic frequency is a kind of signal encryption mode, and transmitting terminal sends signal to be encrypted by infrasonic frequency signal, only has receiving terminal to be also provided with same infrasonic frequency receiving mode, could from the infrasonic frequency signal receiving, parse the information needing.
