and adding a device button in a device list page of the WeChat applet, and starting a Bluetooth searching function. When the WeChat applet searches, the Bluetooth module is connected, namely, the password is prompted to be input, and the submission is confirmed.
The WeChat applet caches the input password before sending a password write instruction to the Bluetooth module, and then sends an encryption verification instruction to the Bluetooth module. The encryption instruction comprises the APPID of the WeChat applet and the MAC address of the Bluetooth module.
The Bluetooth module decrypts the encrypted verification instruction, and compares the decrypted information with the locally stored information to judge the authenticity; if the result is true, the Bluetooth module sends an encryption verification instruction to the WeChat applet and starts a receiving time limit function at the same time. And if the number is false, starting the running time limit function.
And the Bluetooth module sends an encryption verification instruction to the WeChat applet and comprises the MAC address of the Bluetooth module.
The WeChat applet decrypts the encrypted verification instruction, compares the decrypted information with the locally stored information to judge the authenticity, and if the decrypted information is true, the WeChat applet encrypts the decrypted information again and sends the encrypted information to the Bluetooth module. If the result is false, only prompting that the Bluetooth module is not corresponding to the Bluetooth module and not sending any instruction.
The Bluetooth module decrypts the encryption verification instruction, and compares the decrypted information with the local storage information to judge the authenticity; if the result is true, a verification confirmation instruction is sent to the WeChat small program, and meanwhile, a receiving time limit function is started. If the result is false, the operation time limit function is started.
And the WeChat applet receives the verification confirmation instruction and then sends a password writing instruction to the Bluetooth module. And if the result is false, prompting that the Bluetooth module fails to verify.
And the Bluetooth module writes the received password into FLASH within a limited time and returns write-in success information at the same time. If the limited time is exceeded, the password is not written, and the run-time-limit function is started.
And after receiving the write-in success information, the WeChat applet records the Bluetooth deviceID and the password and automatically enters an equipment list page.
In the device list page of the WeChat small program, a point corresponds to an 'on' button (namely a power-on appointed time operation button) of the device, and the WeChat small program is connected with the Bluetooth module according to the Bluetooth deviceID and is successfully connected; and before the WeChat applet sends a power-on specified time instruction to the Bluetooth module, an encryption verification instruction is sent to the Bluetooth module.
The Bluetooth module decrypts the encryption verification instruction, compares the decrypted information with the locally stored information to judge the authenticity, and if the decrypted information is true, the Bluetooth module sends the encryption verification instruction to the WeChat applet and starts receiving time limit. If the number is false, the operation time limit is started.
The WeChat applet decrypts the encrypted verification instruction, compares the decrypted information with the locally stored information to judge the authenticity, and if the decrypted information is true, the WeChat applet encrypts the decrypted information again and sends the encrypted information to the Bluetooth module. If the result is false, only prompting that the Bluetooth module is not corresponding to the Bluetooth module and not sending any instruction.
The Bluetooth module decrypts the encryption verification instruction, and compares the decrypted information with the local storage information to judge the authenticity; if true, a validation confirmation instruction is sent to the WeChat applet. If the result is false, the operation time limit function is started.
And after receiving the verification confirmation instruction, the WeChat applet sends an instruction of closing the power supply for a specified time to the Bluetooth module. The instruction includes cryptographic information.
The Bluetooth module extracts a password part and compares the password part with a password stored in a local FLASH to judge the authenticity of the received power supply closing instruction within a limited time; if true, the power supply is switched off after the power supply is switched on for a specified time; if the result is false, the operation time limit function is started.
Compared with the prior art, the invention has the following beneficial effects:
the Bluetooth module and the WeChat applet are used for performing bidirectional encryption verification and then performing read-write and control operations on the Bluetooth module after the judgment is true, so that an attacker is prevented from forcibly cracking a password by using the program compiled by the attacker and controlling the Bluetooth module. And the Bluetooth module starts the receiving time limit function every time when judging to be true and starts the running time limit function every time when judging to be false. Therefore, the security of the bluetooth module is improved.
