And S02, the mobile network terminal inquires the binding authentication system and acquires a decryption key according to the unique verification code.
S03, the mobile network terminal acquires the encrypted binding key from the lock body and decrypts the encrypted binding key according to the decryption key to acquire the binding key; the encrypted binding key may be written in the lock body, or the encrypted binding key may be generated by encrypting the binding key by the lock body.
S04, the mobile network terminal packs the binding key and the unique verification code and sends the binding key and the unique verification code to a binding authentication system;
s05, the binding authentication system receives the binding key and the unique verification code, judges whether the binding key and the unique verification code have a preset corresponding relation, and if so, executes binding operation; if not, the binding operation is not executed.
In conclusion, since the unique verification codes used by each lock body are different, lawbreakers cannot enter the binding mode of the lock body according to the universal binding codes, and therefore the safety of the intelligent lock is effectively improved.

It should be understood that the unique verification code may also include the lock body hard serial number, the bluetooth MAC address and the device unique identifier, or include a verification number preset by the binding authentication system.
Preferably, the method for determining whether the binding key and the unique verification code have a preset corresponding relationship comprises:
s051, inquiring a preset binding key which is locally stored and corresponds to the unique verification code by the binding authentication system;

It should be clear that, the binding authentication system pre-stores the unique verification code and the preset binding key with the corresponding relationship; when the binding authentication system receives the binding key and the unique verification code, the binding authentication system inquires the preset binding key according to the unique verification code, compares the preset binding key with the binding key, and if the preset binding key is the same as the binding key, the unique verification code and the binding key have a preset corresponding relation.
Preferably, the binding operation comprises:

It should be clear that, the binding authentication system acquires the SN of the mobile network terminal, and establishes a correspondence between the SN of the mobile network terminal and the unique verification code. At this moment, when detecting that the current mobile network terminal obtains the decryption key through the unique verification code, the binding authentication system checks whether the SN code of the current mobile network system is consistent with the stored SN code, and does not send the decryption key to the current mobile network terminal when the SN code of the current mobile network system is inconsistent with the stored SN code, so that the lock body is effectively prevented from being bound again by lawbreakers, and the contact between the lock body and the mobile network terminal is improved.
Preferably, before the mobile network terminal acquires the unique verification code of the lock body, the method further includes the following steps:
s001, the lock body receives a binding request sent by the mobile network terminal;
and S002, the lock body opens a built-in communication module, and a communication channel is established with the mobile network terminal through a wireless communication network.
Specifically, the lock body and the mobile network terminal realize communication through a wireless network, and the wireless network can be a bluetooth network, a WiFi network or other wireless networks capable of realizing wireless communication.
Preferably, the encrypted binding key is formed by encrypting the binding key based on the decryption key, the encrypted binding key being written to the memory of the lock body.
Preferably, the unique verification code further comprises an authentication ID;
after the mobile network terminal obtains the only identifying code of lock body, still include:
and S011, the mobile network terminal stores the authentication ID into a memory of the mobile network terminal.
Preferably, after the binding operation is executed, the following authentication process is further included after the binding operation is executed:
s055, the mobile network terminal encrypts the authentication ID according to a preset encryption algorithm to obtain an encrypted authentication ID;
s056, the mobile network terminal sends the encrypted authentication ID to the lock body;

Specifically, it should be understood that the authentication ID is stored to improve the security of communication between the lock body and the mobile network terminal, and to prevent a situation of error communication. After the mobile network terminal and the lock body are disconnected in communication, authentication is required to be carried out again, namely the steps from S055 to S058 are carried out for authentication, after the authentication is successful, the communication connection between the lock body and the mobile network terminal is realized again, and if the authentication is unsuccessful, the mobile network terminal is not allowed to open the door.
Preferably, the encrypting the authentication ID by the mobile network terminal according to a preset encryption algorithm to obtain an encrypted authentication ID includes:
s0551, the mobile network terminal encrypts verification information according to the decryption key and the binding key, wherein the verification information at least comprises authentication ID and verification random number;
the lock body receives and decrypts the encrypted authentication ID to obtain the authentication ID, and the method comprises the following steps:
s0571, the lock body decrypts the verification information according to the decryption key and the binding key to obtain an authentication ID and a verification random number;
the lock body judges whether the obtained authentication ID is consistent with the authentication ID stored locally, if so, the lock body is allowed to be controlled by the mobile network terminal to open the door lock, and if not, the communication connection between the mobile network terminal and the lock body is disconnected, which comprises the following steps:

s0582, judging whether the obtained authentication ID is consistent with the authentication ID stored locally, if so, allowing the mobile network terminal to control the lock body to open the door lock, and if not, disconnecting the communication connection between the mobile network terminal and the lock body;
after step S058, comprising:
s0591, producing and storing a new verification random number by the lock body, and encrypting the new verification random number according to the decryption key and the binding key to obtain an encrypted verification random number;
s0592, the lock body sends the encrypted verification random number to the mobile network terminal;
s0593, the mobile network terminal decrypts the encrypted verification random number according to the decryption key and the binding key, obtains and stores a new verification random number, and replaces the verification random number with the new verification random number.
It should be clear that, in the authentication process, the verification random number sent by the mobile network terminal and the verification random number pre-stored in the lock body are compared to determine whether they are consistent, and the lock of the lock body can be opened only by the mobile network terminal after they are consistent. After one authentication is completed, the lock body generates a new verification random number, the new verification random number is used for replacing the verification random number, and the new verification random number is used as the verification random number in the next authentication process. Because the random number of verification in each authentication process is different, the lock body can effectively resist replay attack and prevent cracking.
