Housing parts and be installed on its inner circuit board, wherein the core component on the circuit board comprises main control chip 501, includes control module and random password generation module, the Z32H256SUF chip of emerging company during this programme is selected for use; Toggle switch K502 is a trigger module; DTMF generator 503 is an output module, and this programme is selected the HT9200A of Hotel company for use; Solar cell 504, capacitor C 505 is the accumulation of energy module, and diode D506, this programme select IN5819 for use, and note amplifier 507, this programme are selected the SPY0030A of Sunplus company for use, loudspeaker 508.The random password generating algorithm is built among the control chip Z32H256SUF, Closing Switch 502, the authentication number of times is counted, produce a count value, utilize above-mentioned built-in random password generating algorithm, the static factor that count value and authenticating device is built-in is (such as user's name, user account number, one or more in the information such as device hardware sign) carry out computing, obtain random password, and output on the DTMF generator 503, DTMF generator HT9200A converts random password to touch-tone signal, and be sent to and carry out audio frequency on the note amplifier SPY0030A and amplify, deliver to loudspeaker 508 again and report.The novel authenticating device that the utility model embodiment provides is counted the authentication number of times owing to having adopted, and each count value is different, also all is different so authenticate employed password at every turn.The user is input to random password in the client host, uses different passwords to authenticate at every turn, thereby has improved security greatly.
The EEPROM that has 32KB in the Z32H256SU intelligent card chip of selecting for use in this preferred version; be used to store data and program; and the FLASH of 256KB is used for stored programme, function library, incremental data etc. seldom; such as the count results in this programme; just can be stored among the FLASH of Z32H256SU intelligent card chip; be used for realizing power down protection; because its storage space is the non-volatile memory medium type; can realize repeatedly erasable; for the upgrading of program is provided convenience; simultaneously because its non-volatile characteristic also makes the storage of calling program more safe and reliable.
Solar cell 504 and capacitor C 505, diode D506 constitute power circuit in the lump, for above-mentioned verification process provides electric energy.The electric power storage process: solar cell 504 absorbs sun power and converts electric energy to, the circuit loop that constitutes by solar cell 504, diode D504 and capacitor C 505 charges, diode D conducting among Fig. 6, constitute clockwise loop, the electric energy that solar cell 504 converts to is the capacitor C charging, at this moment, the upper end of capacitor C is anodal, and the lower end is a negative pole.After charging finished, diode D was in by state, was used to prevent the capacitor C discharge.The positive pole of capacitor C is connected with the VCC end of main control chip 501 by K switch 502, and negative pole is connected with the GND end of main control chip 501, is main control chip 501 power supplies; The positive pole of capacitor C is connected with the VCC end of DTMF generator HT9200A by K switch 502, and negative pole is connected with the GND end of DTMF generator HT9200A, and HT9200A powers for the DTMF generator.The capacitor C that this programme is selected for use is the big electric capacity of F level, such as the electric capacity that can select 1F/3.3V for use, can increase the ability of accumulation of energy like this.Behind Closing Switch K, the positive pole of capacitor C just is connected with the VCC end of main control chip 501, the circuit turn-on that this moment, capacitor C, Z32H256SU intelligent card chip and DTMF generator HT9200A were formed, electric energy by the capacitor C savings is powered for it, produce random password, and deliver to DTMF generator HT9200A, deliver to loudspeaker output after amplifying by the SPY0030A audio frequency; After K switch was disconnected, the circuit that this moment, capacitor C, Z32H256SU intelligent card chip and DTMF generator HT9200A were formed disconnected, and quits work.
In the novel authenticating device that the utility model provides, because K switch is placed between the positive pole and main control chip VCC end of capacitor C, like this, switch or button are placed on other position relatively, it is the anodal situation about directly being connected of capacitor C with main control chip VCC end, effectively saved electric energy, because in the utility model when not working, K switch is in off-state, capacitor C, the circuit that Z32H256SU intelligent card chip and DTMF generator HT9200A are formed also is in off-state, this moment is consumed power not, and capacitor C and main control chip VCC hold under the direct-connected situation, even also have power consumption when not working.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
