With the development of electronic technology, the application of the coded lock is becoming widespread in daily life of people. Common door locks, car locks and the like have cases of using coded locks. Under normal conditions, when the server and the coded lock keep communication, the server generates an unlocking code according to an unlocking request sent by a user through the terminal equipment and sends the unlocking code to the terminal equipment and the coded lock of the user, the coded lock responds to the input of the unlocking code by the user, and the unlocking is carried out after the unlocking code input by the user is determined to be consistent with the unlocking code received by the user.

And step 200, the server analyzes the equipment password by using a first encryption algorithm to acquire the identification code of the terminal equipment of the user.
Step S300, the server refers to a first preset identification code list according to the identification code of the terminal equipment of the user; the identification codes in the first preset identification code list are identification codes of terminal equipment with unlocking authority for the coded lock.
Wherein the first list of identification codes is stored in the server.
Step 400, if the first preset identification code list includes an identification code consistent with the identification code of the terminal device of the user, the server generates an unlocking password and sends the unlocking password to the terminal device of the user.
And step 500, the coded lock responds to the input of the unlocking code by the user, and the unlocking code is verified.
The unlocking password is input by the user through an input keyboard of the coded lock.
And step S600, if the verification is passed, unlocking the coded lock.
When the terminal device of the user sends an unlocking request to the coded lock, the off-line control method of the coded lock provided by the embodiment firstly adopts the server to verify the unlocking authority of the terminal device of the user, generates the unlocking password after the unlocking authority passes the verification, and sends the unlocking password to the terminal device of the user, then utilizes the coded lock to verify the unlocking password after the user inputs the unlocking password, and unlocks the coded lock after the unlocking authority passes the verification. According to the method, when the coded lock is in the offline state, the unlocking password is generated in real time based on the unlocking request of the user terminal equipment to the coded lock, and the unlocking safety of the coded lock in the offline state is improved.
In some embodiments, the server stores the identification code of the combination lock, and the server in step S400 generates an unlock code, including steps S410 to S420.

It can be understood that the user who unlocks the coded lock may be a different person each time, and therefore, the identification code of the terminal device of the user who unlocks the coded lock each time may also be different, so that the unlocking password generated by using the identification code of the terminal device of the user and the identification code of the coded lock each time when unlocking the coded lock may also be different.
In some embodiments, step S420 generates the unlocking password using the first quantum random array, the identification code of the user' S terminal device, and the identification code of the combination lock based on a second encryption algorithm, including steps S421 to S424.

In some embodiments, the method for verifying the unlocking password by the coded lock in step S500 in response to the user inputting the unlocking password includes steps S510 to S590.
Step S510, inquiring a historical offline unlocking password database based on the unlocking password to judge whether the unlocking password is used for the first time.
It can be appreciated that after the user obtains the unlocking password, the user may leave the password lock without unlocking the password lock for other reasons, but there may be other people who unlock the password lock offline before the user leaves the password lock, so that it is necessary to determine whether the unlocking password is used for the first time in order to improve the security of the password lock.
And step S520, if the unlocking password is used for the first time, storing the unlocking password into the historical offline unlocking password database, and analyzing the unlocking password based on the second encryption algorithm to acquire the identification code of the terminal equipment of the user, the identification code of the coded lock and the first quantum random number.

The second preset identification code list is stored in the coded lock, and the second preset identification code list is consistent with the first preset identification code list.
It can be appreciated that if the duration is longer than the preset duration, the possibility that the unlocking password is stolen in the duration is increased, and a certain potential safety hazard is caused to the user, so that the verification cannot be passed as long as the duration is longer than the preset duration in order to improve the security of the coded lock.
Step S580, if the second preset identification code list includes an identification code consistent with the identification code of the terminal device of the user, verifying whether the identification code of the coded lock is consistent with the preset coded lock identification code.
The preset coded lock identification code is the true identification code of the coded lock, and the preset identification code is stored in the coded lock.
Step S590, if the identification code of the coded lock is consistent with the preset coded lock identification code, the verification is passed.
The method for verifying the unlocking password can further improve unlocking safety of the password lock in an offline state.
In some embodiments, the step S520 of resolving the unlocking password based on the second encryption algorithm to obtain the identification code of the terminal device of the user, the identification code of the coded lock, and the first quantum random number includes steps S521 to S524.
And step 521, resolving the unlocking password based on an inverse function of a second combination function of the second encryption algorithm to obtain the first quantum random array and the intermediate code.
Step S522, parsing the intermediate code based on an inverse function of the first combining function of the second encryption algorithm to obtain the first array and the second array.
Step S523, parsing the first array based on an inverse function of the format conversion function of the second encryption algorithm to obtain an identification code of the terminal device of the user.
And step S524, analyzing the second number group based on the inverse function of the format conversion function of the second encryption algorithm to obtain the identification code of the coded lock.
In some embodiments, before the server sends the unlock code to the terminal device of the user, the server performs encryption processing on the unlock code, and the method of encryption processing includes steps S10 to S70.

And step S20, referring to the updated preset coding table based on the identification code of the terminal equipment of the user so as to acquire a third array.
Illustratively, if the identification code of the terminal device of the user is AHBEF, the third array is 64950.
And step S30, referring to the updated preset encoding table based on the identification code of the server to acquire a fourth array.
Illustratively, if the identification code of the server is GIDJCB, the fourth array is 278319.
Step S40, randomly generating a first random array and a second random array.
Illustratively, the first random array is 435816 and the second random array is 834912.
Step S50, generating a first encryption array based on the third array and the first random array.
