Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the described composition structural representation that has the earphone shield of Mobile Storage Function MSF concurrently of the utility model.
Among the figure:
1, microprocessor; 2, memory; 3, safety chip; 4, earphone interface; 5, modulator-demodulator; 6, rechargeable battery; 7, contactor; 8, USB interface; 9, liquid crystal micro display; 10, miniature keyboard; 11, mode selector switch.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, do to describe in detail further below in conjunction with accompanying drawing 1.
This earphone shield that has Mobile Storage Function MSF concurrently comprises microprocessor 1, memory 2, safety chip 3, earphone interface 4, modulator-demodulator 5, rechargeable battery 6, contactor 7, USB interface 8, liquid crystal micro display 9, miniature keyboard 10, mode selector switch 11.Microprocessor 1 links to each other with memory 2, safety chip 3, modulator-demodulator 5, rechargeable battery 6, liquid crystal micro display 9, miniature keyboard 10, mode selector switch 11 respectively.1 power supply of 6 pairs of microprocessors of rechargeable battery.Memory 2 is used to provide memory space, storage file.Safety chip 3 is accomplished safety related functions, and storage user's various keys and digital certificate realize that simultaneously data encryption and deciphering, digital signature generate and authentication function; The various keys that comprise private key for user are only deposited in the safety chip 3, can't derive.The display screen of liquid crystal micro display 9 can only show delegation's information.Miniature keyboard 10 total upper and lower, left and right, definite, cancellation six press keys can be used for representing six kinds of operations.When the amount of information that on liquid crystal micro display 11, shows surpassed the screen size of display, the upper and lower, left and right button that can operate miniature keyboard showed complete information.When the user need confirm and when cancelling, uses and confirm and the cancellation button some operation.Mode selector switch 11 is buttons, is used for switching the mode of operation of earphone shield, when the user presses the button, switches to earphone shield mode of operation, otherwise is in the mobile storage disc mode of operation.
Modulator-demodulator 5 is connected with microprocessor 1 with earphone interface 4.Modulator-demodulator 5 is used to realize the mutual conversion of audio signal and digital signal.Contactor 7 is used for controlling USB interface 8 and is communicated with the circuit of 6 of rechargeable batteries or cuts out.When the earphone shield utilized USB interface 9 to be connected to personal computer, contactor 7 was opened USB interface 8 and 6 circuit of rechargeable battery, can pass through 8 pairs of battery charge of USB interface.When USB interface 8 was in not-connected status, contactor 7 cut out the circuit of 6 of USB interface 8 and rechargeable batteries.
Before using the earphone shield, need to accomplish earlier initialization to the earphone shield.During initialization, need to generate various keys and the certificate relevant, and be stored in the safety chip 3, and guarantee that various keys can't be derived with the earphone shield.After the initialization, both can be used as the earphone shield, and also can be used as movable storage device and use.In order to protect the fail safe of earphone shield, each earphone shield has a shield password.When the button of mode selector switch 11 is pressed, uses as the earphone shield, otherwise use as mobile storage disc.
When switching to the use of earphone shield pattern, the user need input correct shield password, switches otherwise earphone shield refusal carries out mode of operation.The shield password is made up of eight Arabic numerals.The shield password input mode is following: ten numerals of the screen display of miniscope 9 " 0123456789 "; The user uses the numeral in key location that moves to left and move to right; Use then and move down first bit digital that key confirms to select the shield password; The user adopts this kind mode to select other seven bit digital successively, and the input that acknowledgement key is accomplished the shield password is pressed by end user.
When carrying out bank transfer or carry out the high financial business operation of other security requirement, various sensitive datas show on miniscope 9 like the amount of money, recipient's information such as number of the account.If the information that shows surpasses the size of screen, the user can operate the upper and lower, left and right key to browse complete information.If the user has no objection to the information that shows, can press acknowledgement key, the earphone shield is carried out corresponding crypto-operation and the result is returned to mobile phone through earphone interface; Otherwise the user presses cancel key, and the earphone shield is ignored the request of mobile phone transmission or returned error message.
When switching to the use of mobile storage disc pattern; Can be directly connected to mobile phone through earphone interface; Also can the earphone shield be connected to personal computer, thereby be implemented between mobile phone and the earphone shield, the file transfer under the various situation between mobile phone and mobile phone, between mobile phone and personal computer and between personal computer and personal computer through USB interface.
Above-mentioned execution mode and embodiment; Just form and method for using for the structure that clearly demonstrates the said device of the utility model; But the protection range of the utility model is not limited thereto, as adopts different encapsulating structures, and different shell etc. all falls into the protection range of the utility model.
