S202, decrypting the electronic signature information through the public key, and obtaining a 32-bit electronic password;
the process of decrypting the electronic signature information through the public key is as follows: after obtaining the plaintext M and the signature (r, S), verifying that r and S are integers between (1, n-1), and calculating E ═ SHA (M), W ═ S-1(mod n)；
U1＝EW(mod n)，U2＝rW(mod n)；
X＝U1G+U2Q＝(X1+Y1) Let V be X1 mod n;
s203, matching the 32-bit electronic password with the encrypted signature password;
s204, when matching is right, namely r is V, the verification is successful;

When no USB is connected to charge the battery 602, the connection node between the ninth resistor R9 and the tenth resistor R10 outputs a low level signal to the processor 605, the charging status of the first chip U1 indicates that the pin is in a high impedance state, and at this time, the second chip U2 protects the battery 602, and the battery 602 normally supplies operating current to the smoke detector circuit 603. At this time, by acquiring the voltage output by the abnormality detection circuit 604, the processor 605 can perform low battery detection and output short circuit detection on the battery 602, and can also perform time-limited 8S power-off protection in combination with the existing timer software.
When detecting whether a cigarette cartridge 70 is accessed, the second detection end of the cigarette cartridge detection circuit 603 is in a high-resistance state, the third resistor R3 is a pull-up resistor, when the output voltage of the first detection end of the cigarette cartridge detection circuit 603 is in a high level, it indicates that the cigarette cartridge 70 is accessed, at this time, the processor 605 first obtains the electronic signature information and the encryption information stored in the electronic tag through the NFC communication chip nxp CLRC663, at this time, the information is verified, the verification is divided into two layers, the electronic signature information is firstly verified, after the verification is passed, the obtained encryption information is input to the electronic tag for verification, the electronic tag is stored in a common storage area and an encryption area, the electronic signature information and the encryption information stored in the common storage area are stored in the common storage area, the information stored in the encryption area can be read by the NFC communication chip after the encryption information is verified by the encryption information of the company of the cigarette cartridge 70, the encryption area is factory information of the company, User information and smoking information. After the two layers of verification are passed, the factory information, the user information and the smoking information of the company of the cartridge 70 are sent to the display circuit 607 to be displayed, and a signal input by the air switch is used for outputting a control signal to the first MOS transistor Q1 to control the output power. If either or both of the two layers fail, a prompt is output to the display circuit 607 to prompt the user to refill the cartridge 70.
When the output voltage of the first detection terminal of the cartridge detection circuit 603 is low, it indicates that no cartridge 70 is accessed.
After the cartridge 70 is filled and successfully verified, the processor 605 obtains the remaining capacity of the battery 602 according to the voltage output by the abnormality detection circuit 604, and outputs a control signal to control the first MOS transistor Q1 according to a key signal of the air switch.
The invention can carry out systematic management on the smoke cartridge 70 of the electronic cigarette by carrying out electronic signature verification and encryption verification on the electronic tag, standardizes the product sequence of an enterprise, further improves the identification degree of the product and is convenient for a consumer to identify the correct product.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
