With the development of electronic technology, the application of the coded lock is becoming widespread in daily life of people. At present, a common coded lock is usually provided with a unique code for the coded lock, and the coded lock can be opened when the correct code is input, however, the method is low in safety and is generally only suitable for private home environments, is not suitable for places with large people flow, such as office places, hotels and the like, and can cause serious threat to property safety of users once the unique code of the coded lock is revealed in places with large people flow. Therefore, the embodiment of the application provides a method, a device, equipment and a storage medium for unlocking a coded lock, so as to solve the problems.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a flowchart of an unlocking method of a coded lock according to an embodiment of the present application, and as shown in fig. 1, the unlocking method of a coded lock according to an embodiment of the present application includes steps S101 to S109.
Step S101, responding to an unlocking request of a user for a coded lock, and acquiring identification information of terminal equipment; the user sends the unlocking request by using the terminal equipment;
the terminal device is a mobile terminal device, for example, a mobile phone, a tablet computer, a notebook computer, a wearable device and the like, an APP for unlocking the coded lock is arranged on the terminal device, each coded lock corresponds to a unique APP matched with the coded lock, and it can be understood that the APP can only be downloaded on the terminal device of a designated person with unlocking authority for the coded lock, for example, for the coded lock of a hotel manager office, the unique APP matched with the coded lock of the hotel manager office can only be downloaded on the terminal device of the hotel manager. It can be appreciated that, according to different application scenarios of the coded lock, the coded lock may be downloaded to one or more terminal devices of designated personnel having unlocking authority on the coded lock, for example, the coded lock is a door lock of a company, and then the APP matched with the coded lock may be downloaded to the terminal device of each employee of the company.
Step S102, authenticating the unlocking request of the user according to the identification information.
It can be appreciated that the lock can be unlocked only after the terminal device downloads the original APP, and in order to prevent some illegal persons from developing some pirated APPs to download on its own terminal device to gain illegal benefits, the unlocking request of the user needs to be authenticated.
Step S103, if the authentication passes, obtaining first time information, and generating a first quantum random number sequence by using a quantum random number generator based on the first time information; the first time information is time information when the authentication passes.
It can be understood that, based on the first moment information, the first quantum random number sequence is generated by using the quantum random number generator, so that the uniqueness of the unlocking password generated subsequently can be improved, and the safety of the unlocking method of the coded lock can be improved.
Step S104, acquiring a first identification code and a second identification code; the first identification code is the identification code of the coded lock, and the second identification code is the identification code of the terminal equipment.
Step S105, generating a third identification code according to the first identification code and the second identification code.
For example, the first identification code and the second identification code may be character strings, and the method for generating the third identification code according to the first identification code and the second identification code may include the following steps:
respectively extracting the character of the character string of the first identification code at the appointed position and the character of the character string of the second identification code at the appointed position;
and randomly arranging all the extracted characters to generate the third identification code.
For example, the first identification code is ACDEFG, the second identification code is BGFJDC, the designated positions of the first identification code are in order 1,3,5, and the designated positions of the second identification code are in order 2,4,6, then all the extracted characters are a, D, F, G, J, C, and the third identification code obtained by randomly sorting all the extracted characters is DGCAFJ.
And S106, generating an unlocking password according to the first quantum random number sequence and the third identification code, and replacing the first identification code with the third identification code.
It will be appreciated that some illegal persons may study the unlocking method of the coded lock by stealing the first identification code, but if the third identification code is used to replace the first identification code after each unlocking, the coded lock cannot be unlocked even if the illegal persons study the unlocking method of the coded lock according to the first identification code.
And step S107, the unlocking password is sent to the terminal equipment.
And step S108, responding to the input of the unlocking password by the user, and acquiring the unlocking password.
And step 109, unlocking the coded lock according to the unlocking code.
According to the unlocking method of the coded lock, the unlocking password is generated according to the first quantum random number sequence, the first identification code and the second identification code when the authentication is passed through by authenticating the unlocking request of the user, so that the safety of the unlocking method of the coded lock is improved, and the unlocking method of the coded lock provided by the embodiment is suitable for private houses and public places.
As shown in fig. 2, in some embodiments, the identification information includes a first algorithm, and the coded lock is provided with a second algorithm that is the same as the first algorithm, and step S102 includes steps S1021 to S1025.
Step S1021, randomly generating a first random array.
Wherein the first random array may be generated by a random number generator.
Step S1022, obtaining the first algorithm, and processing the first random array by using the first algorithm to obtain a first authentication array.
It is understood that the first algorithm is an algorithm in the APP of the master, and the terminal device only downloads the APP of the master, and the identification information includes the first algorithm.
Step S1023, obtaining the second algorithm, and processing the first random array by using the second algorithm to obtain a second authentication array.
Step S1024, comparing and analyzing the first authentication data set and the second authentication data set.
Step S1025, if the first authentication array is consistent with the second authentication array, determining that the authentication passes.
It will be appreciated that, to increase the security of the unlocking method of the combination lock, the authentication pass can be determined only when the first authentication array is identical to the second authentication array.
As shown in fig. 3, in some embodiments, the third identification code is a first character string, and step S106 includes steps S1061 to S1065.
Step S1061, randomly replacing each number in the number display column in the preset encoding table with any number, to obtain the adjusted preset encoding table.
Illustratively, table 1 is the preset encoding table, and table 2 is the adjusted preset encoding table.
It can be appreciated that by adjusting the preset encoding table, the randomness of the unlocking password generated subsequently can be further improved, so that the security of the unlocking method of the coded lock is further improved.

Step S1062, consulting the adjusted preset encoding table based on the third identification code to obtain a number sequence corresponding to the third identification code.
For example, if the third identification code is DGCAFJ, the number column corresponding to the third identification code is 3,0,9,2, 15, 13.
Step S1063, randomly inserting each prime number in the first quantum random number sequence into the number sequence corresponding to the third identification code, to obtain an initial unlocking password.
For example, the first quantum random number sequence is 2,4,5,6,8, the number sequence corresponding to the third identification code is 3,0,9,2, 15, 13, the prime numbers in the first quantum random number sequence are 2 and 5, 2 and 5 are randomly inserted into the number sequence 3,0,9,2, 15, 13 corresponding to the third identification code to obtain a new number sequence 3,0,2,9,2, 15,5, 13, and the new number sequence is used as the initial unlocking password to obtain the initial unlocking password 3029215513.

Step S1064, selecting the number of the initial unlocking password at the designated position.
For example, the initial unlocking password is 3029215513, the designated positions of the initial unlocking password are in the order of 1,3,5,7 and 9, and all the numbers selected are 3,2,2,5,1.
Step S1065, generating the unlocking password according to all the selected numbers.
The unlocking password may be generated by selecting all the digits according to the order of the digits.
For example, the initial unlocking password is 3029215513, the designated positions of the initial unlocking passwords are in the order of 1,3,5,7 and 9, all the selected digits are 3,2,2,5,1, and the unlocking password generated according to the ordering mode of all the selected digits is 32251.
As shown in fig. 4, in some embodiments, step S109 includes steps S1091 through S1095.
Step S1091, obtaining all historical unlocking passwords from an unlocking password database, and judging whether the unlocking passwords are used for the first time according to all the historical unlocking passwords.
Step S1092, if the unlock code is used for the first time, obtaining second time information, where the second time information is time information when the user inputs the unlock code on the code lock.
It can be understood that if the unlocking password is not used for the first time, a certain potential safety hazard may exist in the unlocking of the coded lock, and the user is required to resend an unlocking request for unlocking the coded lock at the APP of the terminal device.
Step S1093, calculating a duration between the first time information and the second time information.
Step S1094, comparing the duration with a preset duration.
And step 1095, unlocking the coded lock and storing the unlocking password into the unlocking password database if the duration is smaller than the preset duration.
It can be understood that if the duration is not less than the preset duration, it may be that the user does not unlock the coded lock after obtaining the unlocking code, and at this time, some illegal personnel may steal the unlocking code to unlock the coded lock, and by comparing the duration with the preset duration, when the duration is less than the preset duration, the safety of the method for unlocking the coded lock may be further improved.
In some embodiments, before the unlocking password is sent to the user, the method further includes encrypting the unlocking password, as shown in fig. 5, and the method for encrypting the unlocking password includes steps S501 to S507.
Step S501, obtaining third time information, and generating a second quantum random number sequence by using the quantum random number generator based on the third time information; the third time information is time information when the unlocking password is generated.
Step S502, referring to a preset encoding table according to the second quantum random number sequence, and generating a first encrypted string.
It can be understood that the second quantum random number sequence is generated by using the quantum number random generator, and a preset encoding table is consulted according to the second quantum random number sequence to generate a first encryption character string, so that timeliness and uniqueness of the first encryption character string can be improved, and the effect of encrypting the unlocking password can be improved.
For example, referring to a preset encoding table according to the second quantum random number sequence, generating the first encrypted character string may be to replace each number in the second quantum random number sequence with a character one by one according to the second quantum random number sequence referring to the preset encoding table.
For example, the second quantum random number sequence is 0,1,3,5,7,6, the preset encoding table is table 1, and the first encrypted string is abddfhg.
Step S503, randomly generating a second random array and a third random array, and referring to the preset encoding table according to the second random array and the third random array to obtain a second character string and a third character string; the second character string is a character string corresponding to the second random array, and the third character string is a character string corresponding to the third random array;
wherein the second random array and the third random array may be generated using a random number generator.
For example, the first random array is 4,6,9,0,1,5, the second random array is 3,9,2,7,9,0, the preset encoding table is shown in table 1, the second string is EGJABF, and the third string is DJCHJA.
Step S504, the characters of the second character string and the third character string at the appointed position are selected respectively.
For example, the second string is EGJABF, the third string is DJCHJA, the specified positions of the first string are in order 1,3,5, and the specified positions of the second string are in order 2,4,6, and then all the selected characters are E, J, B, J, H, a.
Step S505, a second encryption character string is generated according to all the selected characters.
For example, the generating the second encrypted string according to all the selected characters may be generating the second encrypted string after randomly ordering all the selected characters.
For example, the selected characters are E, J, B, J, H, a, and the character sequence generated by randomly sequencing all the selected characters is B, H, J, E, a, J, and the generated second encrypted character string is the character EJBJHA.
And step S506, encrypting the unlocking password by adopting the first encryption character string to obtain a first encryption unlocking password.
And step S507, encrypting the first encryption unlocking password by adopting the second encryption character string to obtain a second encryption unlocking password.
