In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is configured to communicate with the internet wirelessly.

In this embodiment, there is provided a binding method of an intelligent door lock, and fig. 2 is a flowchart of a binding method of an intelligent door lock according to an embodiment of the present invention, where the flowchart includes the following steps:

step S202, a client of an equipment management application sends a binding request to a server, wherein the binding request carries an application identifier of the equipment management application and a wireless communication address of an intelligent door lock to be bound;

step S204, the equipment binding state information fed back by the server indicates that the intelligent door lock is in an unbound state, and the client sends verification information to the intelligent door lock, wherein the verification information is used for verifying input information received by the intelligent door lock;

step S206, the client sends the verification result fed back by the intelligent door lock to the server;

step S208, the client receives authentication information dynamically generated by the server according to the verification result, wherein the authentication information carries an authentication key group for carrying out binding authentication on the intelligent door lock according to the binding request;

step S210, the client sends a confirmation message corresponding to the authentication information and fed back by the intelligent door lock to the server;

step S212, the client receives the binding instruction sent by the server and triggers an account binding process of the intelligent door lock in response to the binding instruction.

Optionally, in this embodiment, before the client initiates the binding application to the server, the bluetooth broadcast of the smart door lock may be, but is not limited to, ensured to be unlocked, then the searched bluetooth list is displayed in the display interface of the client of the device application, and the user may select one bluetooth device in the bluetooth list as the smart door lock to be bound according to the need. Wherein each bluetooth device has a wireless communication address (bluetooth MAC), and each different device management application has an application identifier, such as an APP ID identifier, matched with itself.

Optionally, in this embodiment, after the client establishes bluetooth connection with the intelligent door lock by searching for the wireless communication address of the intelligent door lock, the client initiates a binding request of the intelligent door lock to the server, where the binding request carries an APP ID of the client and a bluetooth MAC of the intelligent door lock. The server identifies the current states of the intelligent door lock and the client according to Bluetooth MAC and APP ID identifications of the intelligent door lock in the binding request, wherein the current states of the intelligent door lock and the client at least comprise two states of binding or unbinding. When the intelligent door lock is in an unbound state as a result of the identification, the client randomly generates a verification code, such as a 6-bit digital verification code. And issuing the verification code and the APP ID of the client to the intelligent door lock together for verifying the input information received by the intelligent door lock.

It should be noted that, after the smart door receives the verification code issued by the client, the smart door will actively light the numeric keypad on the smart door, and the user inputs the verification code on the numeric keypad according to the prompt of the client. After the verification is successfully input, the intelligent door lock can verify the verification code input by the user, if the user inputs an error or the verification code is not input within a specified time (such as 30 seconds), the verification is failed, the intelligent door lock can actively report a message of the verification failure to the client, and meanwhile the intelligent door lock exits from the binding mode.

And if the verification code input by the user is successfully verified by the intelligent door lock, sending a message of the verification success to the server. The server dynamically generates authentication information according to the APP ID identification of the client and the Bluetooth MAC of the intelligent door lock carried in the binding request, wherein the authentication information can include, but is not limited to, binding authentication for the intelligent door lock. In the practical application process, the form and the content of the authentication information are not limited, and can be, for example, a service key, a bluetooth key, an authentication code and the like.

Further, after the intelligent door lock receives the authentication information issued by the server, the intelligent door lock actively reports a confirmation message corresponding to the authentication information to the client, and the confirmation message is sent to the server through the client. After receiving the confirmation message of the authentication information received fed back by the intelligent door lock, the server can send a binding instruction to the client, and the client correspondingly binds the instruction to trigger the account binding process of the intelligent door lock.

It will be appreciated that in step S208, the client receives authentication information dynamically generated by the server according to the verification result, and the authentication information is generated by the server each time the client issues a new binding request, in relation to each binding request issued by the client. That is, the key for binding authentication of the intelligent door lock is changed continuously with the binding request initiated by the client.

Through the above embodiment provided by the application, the server dynamically generates the authentication key set for binding authentication to the intelligent door lock according to the verification result obtained by the intelligent door lock on the verification information received each time, and the server sends the binding instruction according to the confirmation message of the key received by the intelligent door lock. In other words, by adopting the technical scheme, the key data in the intelligent door lock binding process is encrypted and checked, the risk of the key data being attacked is reduced, and the safety of data transmission in the intelligent door lock binding process is improved.

In an optional embodiment, the step S208 of receiving, by the client, authentication information dynamically generated by the server according to the verification result includes:

under the condition that the server checks the application identifier and the communication address carried in the binding request successfully, the client receives the Bluetooth key sent by the server and sends the Bluetooth key to the intelligent door lock;

After the client sends the Bluetooth key confirmation message fed back by the intelligent door lock to the server, the client receives the service key sent by the server and sends the service key to the intelligent door lock;

after the client sends the service key confirmation message fed back by the intelligent door lock to the server, the client receives the authentication code sent by the server and sends the authentication code to the intelligent door lock;

the authentication information comprises a Bluetooth key, a service key and an authentication code.

In the embodiment, after receiving the message that the verification code reported by the intelligent door lock is successfully verified, the server verifies the APP ID and the bluetooth MAC carried in the binding request, and replies the verification result to the intelligent door lock. The intelligent door lock feeds back a confirmation message of 'the received check result' to the server. After receiving the confirmation message, the server sends the Bluetooth key to the client through the hypertext transfer security protocol, and the client sends the Bluetooth key to the intelligent door lock after receiving the Bluetooth key. And at the same time the bluetooth key is stored in the client.

It should be noted that, in the process that the server sends the bluetooth key to the intelligent door lock, the server does not directly send the bluetooth protocol to the client, but the bluetooth key is carried in the reply message through the hypertext transfer security protocol interface, and the client sends the bluetooth key in the reply message to the intelligent door lock after receiving the reply message.

Optionally, in this embodiment, after the smart door receives the bluetooth key issued by the server, a bluetooth key confirmation message is fed back to the client, and the client calls the hypertext transfer security protocol to send the bluetooth key confirmation message to the server. The server sends the service key to the client at the hypertext transfer security protocol interface. And after receiving the service key, the client sends the service key to the intelligent door lock. Notably, unlike the server's first issued bluetooth key, the second issued traffic key is an encrypted key since the smart door lock has received the server's issued bluetooth key.

Optionally, in this embodiment, after the intelligent door lock receives the encrypted service key, a confirmation message of "the received service key" is fed back to the server, where the intelligent door lock sends the confirmation message to the client first, and then the client transmits the confirmation message to the server by calling the hypertext transfer security protocol in the server. After the server receives the confirmation message, the authentication code is issued through the interface of the hypertext transfer security protocol, and is sent to the client, and meanwhile, the authentication code is stored in the memory of the client.

It should be noted that, before the server issues the authentication code to the intelligent door lock, the bluetooth key and the encrypted service key are already stored in the intelligent door lock, so the authentication code issued by the server for the third time is an encrypted key, and the authentication code is a key encrypted twice by the bluetooth key and the service key. Namely, firstly, the service key is encrypted for the first time by using the Bluetooth key, and then, the encrypted service key is encrypted for the second time by using the authentication code.

By adopting the technical scheme, after the client initiates the binding request, the server can send the bluetooth key, the service key and the authentication code to the client and the intelligent door lock in sequence, and the key data in the binding process is encrypted twice by using the bluetooth key, the service key and the authentication code. The complexity of data processing in the binding process is enhanced, and the attack of an attacker on the binding data is avoided, so that the security of data transmission is improved.

As an alternative embodiment, the client sends the service key to the intelligent door lock, including:

the client encrypts the service key by using a Bluetooth key to obtain a first encryption result;

And the client sends the first encryption result to the intelligent door lock so that the intelligent door lock decrypts the first encryption result by using the Bluetooth key to obtain the service key.

In this embodiment, the server may, but is not limited to, have sent the bluetooth key to the client before sending the service key to the smart door lock, and the bluetooth key is stored in the memory of the client. The client also sends the bluetooth key to the intelligent door lock and stores the bluetooth key in the intelligent door lock. After the server sends the service key to the client, the client encrypts the service key by using the pre-stored Bluetooth key to obtain a first encryption result, and sends the first encryption result to the intelligent door lock.

Optionally, in this embodiment, after the smart door receives the first encryption result sent by the client, the smart door may, but is not limited to, decrypt the first encryption result with a pre-stored bluetooth key to obtain the service key. That is, the service key issued by the server is not directly sent to the intelligent door lock, but after the client performs encryption processing, the encrypted service key is sent to the intelligent door lock. Assuming that the bluetooth key corresponds to a key, the key is used to crack the encrypted service key.

By adopting the technical scheme, in the process of transmitting the service key among the server, the client and the intelligent door lock, the service key is encrypted and decrypted by utilizing the Bluetooth key, so that the transmission of the service key has higher security, and the security of data transmission in the intelligent binding process is indirectly improved.

As an alternative embodiment, the client sending the authentication code to the smart door lock includes at least one of:

the client encrypts the authentication code by using the Bluetooth key to obtain a second encryption result; the client sends the second encryption result to the intelligent door lock so that the intelligent door lock decrypts the second encryption result by using the Bluetooth key to obtain an authentication code;

the client encrypts the authentication code by using the service key to obtain a third encryption result; and the client sends the third encryption result to the intelligent door lock so that the intelligent door lock decrypts the third encryption result by using the service key to obtain the authentication code.

In this embodiment, the authentication code C sent by the client is received by the intelligent door lock and encrypted, and the authentication code C can be identified by decrypting the authentication code C by the intelligent door lock. The process of decrypting the encrypted authentication code C by the intelligent door lock at least comprises the following two cases: one is to encrypt directly with the bluetooth key a stored in the smart door lock.

According to the embodiment provided by the application, before issuing the authentication code, the server issues the Bluetooth key and the service key successively, and encrypts the service key after the client receives the service key. That is, the bluetooth key and the encrypted service key are stored in the memory of the client before the server sends the authentication code to the client. Then, the process of the server issuing the authentication code to the intelligent door lock at least comprises the following two cases:

first case: the server sends the authentication code to the client, the client encrypts the authentication code by using a pre-stored bluetooth key, and then sends the encrypted authentication code to the intelligent door lock, for example, the authentication code C is encrypted by using a bluetooth key a, so as to obtain an encrypted authentication code C. Because the authentication code received by the intelligent door lock is an authentication code which is encrypted, the intelligent door lock cannot directly read the encrypted authentication code. The encrypted authentication code C is required to be decrypted by utilizing a Bluetooth key A stored in the intelligent door lock in advance, so that the authentication code is obtained;

second case: the server sends the authentication code to the client, and the client encrypts the authentication code by using a pre-stored service key to obtain a third encryption result, wherein the third encryption result comprises the encrypted authentication code. For example, the service key B is encrypted by using the bluetooth key a to obtain an encrypted service key B, and then the authentication code C is encrypted by using the encrypted service key B to obtain an encrypted authentication code C. After the client sends the encrypted authentication code C to the intelligent door lock, the intelligent door lock decrypts the encrypted authentication code C by using the pre-stored service key B, thereby obtaining the authentication code.

It should be noted that, in the first case, after the client receives the authentication code sent by the server, the authentication code is encrypted only once by using the bluetooth key. In the second case, since the service key stored in the client is a key that has been encrypted using the bluetooth key, after receiving the authentication code sent by the server, the client encrypts the authentication code again using the encrypted service key, that is, in the second case, the client actually encrypts the authentication code twice after receiving the authentication code (to obtain the third encryption result). After the third encryption result is sent to the intelligent door lock, the intelligent door lock firstly decrypts the third encryption result once by using the encrypted service key to obtain an intermediate result; and then, the result between the Bluetooth key pairs is decrypted for the second time to obtain the authentication code in the original state issued by the server.

By adopting the technical scheme, one of the two conditions can be set as a mode that the client sends the authentication code to the intelligent door lock according to the requirement. In the two modes, the client encrypts the authentication code sent by the server, so that the interaction between the intelligent door lock and the client has higher security.

Optionally, the client sends the verification result fed back by the intelligent door lock to the server, including:

and the client calls a hypertext transfer link to send the verification result to the server so that the server sends the authentication information in an interface corresponding to the hypertext transfer link.

It should be noted that the hypertext transfer link may include, but is not limited to, an access request in https, and the client may send not only the verification result fed back by the smart door lock to the server, but also a confirmation message fed back by the smart door lock to the server through an interface of https. In addition, the server also performs data transmission through https interface in the process of sending the Bluetooth key, the service key and the authentication code to the client. That is, the interaction between the client and the server is through the https interface.

By adopting the technical scheme, in the process of data transmission between the client and the server through the hypertext transmission link, the data is encrypted once or more times, so that the data interaction between the client and the server has higher security.

As an optional implementation manner, the client triggers an account binding process of the intelligent door lock in response to the binding instruction, including:

The client sends binding information to the server, wherein the binding information carries a user account matched with the client;

and the client receives a binding result returned by the server, wherein the binding result is used for indicating that the user account and the intelligent door lock are bound.

In the above embodiment provided by the present application, after the server issues the bluetooth key, the service key and the authentication code to encrypt the data in the binding process, the intelligent door lock replies a confirmation message of encryption completion to the server (i.e. the intelligent door lock receives the confirmation message fed back after the authentication issued by the service for the last time). After receiving the confirmation message, the client sends the confirmation message to the server, and the server can send binding information to the client according to the confirmation message. The binding information at least comprises a user account matched with the client.

The client sends the binding information to the intelligent door lock, then sends the confirmation message replied by the intelligent door lock to the server, and the server sends an instruction for carrying out next binding to the client to start the binding process of the user account. After the binding between the user account and the intelligent door lock is completed, the server sends a binding completion result to the client so as to indicate that the binding flow of the intelligent door lock is completed completely.

In an optional embodiment, before the client of the device management application sends the binding request to the server, the method further includes:

under the condition that the intelligent door lock is in a Bluetooth broadcasting state, the client side displays a Bluetooth identification list which is allowed to be connected currently;

responding to a selection operation executed in the client, and determining a door lock Bluetooth identifier matched with the selected intelligent door lock;

the client generates a binding request by using an application identifier of the device management application and a wireless communication address of the intelligent door lock matched with the Bluetooth identifier of the door lock, wherein the wireless communication address comprises a Bluetooth communication physical address.

In the above embodiments provided in the present application, before binding processing is performed on the intelligent door lock, it is required to ensure that the intelligent door lock has opened a bluetooth broadcast, and a bluetooth identifier of a bluetooth device that can be currently connected will be displayed in an application interface of the client. The bluetooth identifier list allowing connection may include, but is not limited to, a door lock bluetooth identifier of the intelligent door lock, and may also include a sound box bluetooth identifier of the intelligent sound box, a bluetooth identifier of the intelligent air conditioner, a bluetooth identifier of the intelligent refrigerator, and the like.

It can be understood that the number of bluetooth devices that the client can search for can be one or more, and then bluetooth identifiers of all the intelligent door locks that allow connection are displayed in the form of a bluetooth identifier list in the application interface of the client. After the user selects and operates in the application interface of the client, the door lock Bluetooth identification of the selected intelligent door lock can be determined.

After determining the bluetooth door lock identifier, the client may generate a binding request by using its own application identifier, for example, APP ID, and a wireless communication address (such as bluetooth MAC) of the smart door lock that matches the bluetooth door lock identifier selected, where the application identifier of each client is a unique identifier that matches the client. When the client sends a binding request to the server, the unique identification matched with the client and the Bluetooth MAC of the intelligent door lock are reported to the server together.

It should be noted that, in the foregoing embodiments of the present application, the execution body is a client of a device management application, and in order to better understand the present application, in this embodiment of the present application, a binding method of an intelligent door lock is further provided, which is applied to a target server, and specifically, as shown in fig. 3, the flow includes the following steps:

step S302, a server receives a binding request sent by a client of an equipment management application, wherein the binding request carries an application identifier of the equipment management application and a wireless communication address of an intelligent door lock to be bound;

step S304, responding to the binding request, the server sends equipment binding state information to the client to indicate the client to send verification information to the intelligent door lock under the condition that the equipment binding state information indicates that the intelligent door lock is not bound, wherein the verification information is used for verifying input information received by the intelligent door lock;

Step S306, the server receives a verification result fed back by the intelligent door lock, which is sent by the client;

step S308, based on the verification result, the server dynamically generates authentication information and sends the authentication information to the client, wherein the authentication information carries an authentication key group for carrying out binding authentication on the intelligent door lock according to the binding request;

step S310, the server receives a confirmation message corresponding to the authentication information, which is fed back by the intelligent door lock and sent by the client;

step S312, the server sends a binding instruction value client to instruct the client to trigger an account binding process of the intelligent door lock in response to the binding instruction.

Through the steps, after the server receives the binding request sent by the client, the server can identify the current states of the client and the intelligent door lock according to the APP ID of the client and the MAC of the Bluetooth capable of locking the door. When the identification result is that the intelligent door lock is in an unbound state, the server dynamically generates authentication information according to the APP ID of the client carried in the binding request and the Bluetooth MAC of the intelligent door lock, so as to be used for binding and authenticating the intelligent door lock.

By adopting the technical scheme, the data in the intelligent door lock binding process is bound and authenticated (such as encryption and verification) in a mode of dynamically issuing authentication information through the server, so that the risk of attacking key data is reduced, and the safety of data transmission in the intelligent door lock binding process is improved.

In an alternative embodiment, dynamically generating authentication information based on the verification result and transmitting the authentication information to the client may be implemented by:

under the condition that verification of the application identifier and the communication address carried in the binding request is successful, the server sends a Bluetooth key to the client so as to instruct the client to send the Bluetooth key to the intelligent door lock;

after receiving the Bluetooth key confirmation message fed back by the intelligent door lock, the server sends a service key to the client so as to instruct the client to send the service key to the intelligent door lock;

after receiving the service key confirmation message fed back by the intelligent door lock, the server sends an authentication code to the client and sends the authentication code to the intelligent door lock.

In this embodiment, after the server receives the message that the verification reported by the intelligent door lock is successful, the server sequentially sends the bluetooth key, the service key and the authentication code to the client. The specific process is as follows: after receiving the message of successful verification, the server sends the Bluetooth key to the client so as to instruct the client to send the Bluetooth key to the intelligent door lock; after receiving a confirmation message of 'received Bluetooth key' replied by the intelligent door lock, the server sends the service key to the client so as to instruct the client to send the encrypted service key to the intelligent door lock; after the server receives the confirmation message of the service key received returned by the intelligent door lock, the server sends an authentication code to the client so as to instruct the client to send the encrypted authentication code to the intelligent door lock.

It should be noted that, before the server sends the service key to the client, the memory of the client has stored the bluetooth key, after the client receives the service key, the service key is encrypted by using the bluetooth key, and then the encrypted service key is sent to the intelligent door lock.

Further, before the server sends the authentication code to the client, the bluetooth key and the encrypted service key are stored in the memory of the client, and after the client receives the authentication code, the authentication code is encrypted by using the pre-stored bluetooth key and the encrypted service key, so that the authentication code is transmitted to the intelligent door lock in an encrypted form.

By adopting the technical scheme, the server can sequentially send the Bluetooth key, the encrypted service key and the encrypted authentication code to the intelligent door lock, so that the safety of data transmission between the server and the intelligent door lock is higher, an attacker is prevented from attacking data in the intelligent door lock binding process, and the benefit loss of a user is reduced.

As an optional implementation manner, the receiving the verification result of the intelligent door lock feedback sent by the client includes:

the server receives the verification result sent by the client-side calling the hypertext transfer link, and sends authentication information in an interface corresponding to the hypertext transfer link based on the verification result.

It should be noted that, through the above hypertext transfer link, the server may receive, in addition to the verification result sent by the client, a confirmation message fed back by the intelligent door lock. In addition, the server also needs to send the bluetooth key, the service key and the authentication code to the client in sequence through the hypertext transfer link.

By adopting the technical scheme, in the process of data transmission between the client and the server through the hypertext transmission link, the data is encrypted at least once, so that the risk of data attack is reduced, and the safety of data transmission is improved.

As an optional implementation manner, the sending a binding instruction to the client to instruct the client to trigger an account binding process of the intelligent door lock in response to the binding instruction includes:

the method comprises the steps that a server receives binding information sent by a client, wherein the binding information carries a user account matched with the client;

and the server returns a binding result to the client, wherein the binding result is used for indicating that the user account and the intelligent door lock are bound.

In the above embodiment provided by the application, after the server sequentially sends the bluetooth key, the service key and the authentication code to the intelligent door lock, the server receives a confirmation message replied by the intelligent door lock, and issues binding information to the client according to the confirmation message, so as to instruct the client to send the binding information to the intelligent door lock.

After receiving the confirmation message of the binding information received returned by the intelligent door lock, the server sends an instruction for carrying out next binding to the client, and the binding process of the user account is started. After the binding between the user account and the intelligent door lock is completed, the server sends a binding completion result to the client so as to indicate that the binding flow of the intelligent door lock is completed completely.

By adopting the technical scheme, the data in the binding process of the intelligent door lock can be encrypted, and the technical problem of low data security caused by the fact that Bluetooth connection is established between the client and the intelligent door lock in the prior art and the binding process can be executed according to verification information is solved.

It should be noted that, the execution main body of the above steps is an intelligent door lock binding server, in order to better understand the technical solution of the present invention, the present application further provides a binding method of an intelligent door lock, applied to an intelligent door lock, specifically, as shown in fig. 4, the process includes the following steps:

step S402, the intelligent door lock receives verification information sent by the client, wherein the verification information is used for verifying the received input information;

step S404, the intelligent door lock feeds back the verification result and sends the verification result to the server through the client to instruct the server to send authentication information dynamically generated according to the verification result to the client;

Step S406, the intelligent door lock feeds back a confirmation message corresponding to the authentication information to instruct the client to send the authentication information to the server;

step S408, the intelligent door lock starts an account binding process.

In this embodiment, when it is confirmed that the smart door lock is in an unbound state, the smart door lock receives a verification code (e.g., a verification code with a 6-digit number) randomly generated by the client and an APP ID generated by the client itself. And the user inputs a verification code of 6 digits on a numeric keypad of the intelligent door lock according to the prompt of the client, and after the input is successful, the intelligent door lock can verify the verification code input by the user.

If the verification code input by the user is verified successfully by the intelligent door lock, a message (verification result) of the verification success is sent to the client so as to instruct the client to send the message (verification result) of the verification success to the service. And then the intelligent door lock can receive the authentication information dynamically generated by the server according to the verification result, and replies a confirmation message of 'received authentication information' to the client so as to instruct the client to send the authentication information to the server, and further, the binding flow of the intelligent door lock is started.

It should be noted that, the user inputs the verification code on the numeric keypad according to the prompt of the client, and the method further includes: if the user inputs an error or does not input the verification code within a specified time (such as 30 seconds), the verification fails, the intelligent door lock actively reports a message of the verification failure to the client, and the intelligent door lock exits the binding mode.

By adopting the technical scheme, the intelligent door lock receives the verification code randomly generated by the client and verifies the verification code. Under the condition that the verification is successful, the intelligent door lock can receive authentication information dynamically generated by the server according to the verification result and reply a confirmation message to the server, so that the binding flow of the intelligent door lock is started. According to the technical scheme, verification information and confirmation information are dynamically obtained in the data transmission process between the intelligent door lock and the client side and between the intelligent door lock and the server, and data in the intelligent door lock binding process are encrypted, so that the data are irregular and circulated. The intelligent door lock binding method and device avoid the attack on the intelligent door lock binding process by using the simulation data, improve the reliability of the intelligent door lock binding process and improve the safety of data transmission.

Optionally, the feeding back the verification result and sending the verification result to the server through the client to instruct the server to send authentication information dynamically generated according to the verification result to the client, including:

the intelligent door lock receives a Bluetooth key sent by a client;

the intelligent door lock sends a confirmation message of the Bluetooth key to the client so as to instruct the client to send the confirmation message of the Bluetooth key to the server;

After the server receives the confirmation message of the Bluetooth key sent by the client, the intelligent door lock receives the service key sent by the client;

the intelligent door lock sends a confirmation message of the service key to the client so as to instruct the client to send the confirmation message of the service key to the server;

after the server receives the confirmation message of the service key sent by the client, the intelligent door lock receives the authentication code sent by the client;

In this embodiment, the intelligent door lock sequentially receives the bluetooth key, the service key and the authentication code sent by the server. It should be noted that, the bluetooth key a received for the first time is not encrypted; the second received service key B is the key information after the client encrypts the service key B by using the bluetooth key; the third received authentication code C is key information obtained by encrypting the authentication code C by the client using the bluetooth key and/or the encrypted service key.

By adopting the technical scheme, in the intelligent door lock binding process, key data in the binding process are encrypted twice by utilizing the Bluetooth key, the service key and the authentication code. The safety of the data interaction process between the intelligent door lock and the client side and between the intelligent door lock and the server is higher, and the reliability of data transmission is further improved.

As an optional implementation manner, the receiving service key sent by the client includes:

the intelligent door lock receives a first encryption result sent by the client, wherein the first encryption result is obtained by encrypting a service key by the client by using a Bluetooth key;

the intelligent door lock decrypts the first encryption result by using the Bluetooth key to obtain the service key.

It should be noted that, after the smart door receives the first encryption result sent by the client, the service key B included in the first encryption result B is not directly identified, but the service key B issued by the server can be obtained only by performing decryption processing using the first encryption result B of the bluetooth key stored in the smart door in advance.

Optionally, the authentication code sent by the receiving client includes at least one of the following:

the intelligent door lock receives a second encryption result sent by the client, wherein the second encryption result is obtained by encrypting the authentication code by the client through a Bluetooth key;

the intelligent door lock decrypts the second encryption result by using the Bluetooth key to obtain an authentication code;

the intelligent door lock receives a third encryption result sent by the client, wherein the third encryption result is obtained by encrypting the authentication code by the client by using the service key;

And the intelligent door lock decrypts the third encryption result by utilizing the service key to obtain the authentication code.

It should be noted that, in this embodiment, the authentication code C sent by the client is received by the intelligent door lock and is encrypted, and the authentication code C can be identified by decrypting the authentication code C by the intelligent door lock. The process of decrypting the encrypted authentication code C by the intelligent door lock at least comprises the following two cases: one is to directly utilize the bluetooth key a stored in the intelligent door lock to encrypt the authentication code C, so as to obtain the authentication code C; the other is that firstly, the service key B stored in the intelligent door lock is used for carrying out one-time decryption processing on the authentication code C, and then the Bluetooth key A stored in the intelligent door lock is used for carrying out a second-time decryption processing, so that the authentication code C issued by the server can be obtained.

By adopting the technical scheme, in the practical application process, the intelligent door lock can select a corresponding decryption processing mode according to encryption processing of the authentication code by the client, and the two modes all require the intelligent door lock to decrypt the encrypted authentication code, so that the authentication code has higher privacy in the transmission process, and further the security of data transmission is improved.

As an alternative embodiment, the above-mentioned process of starting account binding includes:

the intelligent door lock receives binding information sent by a client, wherein the binding information carries a user account matched with the client;

based on the user account, the intelligent door lock starts an account binding process.

It should be noted that, after the intelligent door lock receives the binding information sent by the client and sends the confirmation information to the server through the client, the user account matched with the client and carried in the binding information can be used for binding with the intelligent door lock.

In order to better understand the above embodiments, the present application further provides an overall flowchart of a binding method of an intelligent door, specifically, as shown in fig. 5:

after the APP and the door lock are connected through Bluetooth, the APP end initiates a binding application to the Server end, requests to randomly generate a verification code (6-bit number) successfully, sends the verification code and APP ID information of the verification code to the intelligent door lock, and prompts a user to input the verification code in the intelligent door lock.

It should be noted that, the intelligent door will initiatively lighten the digital keyboard after receiving the verification code issued by the APP, the user inputs the verification code in the intelligent door according to the prompt of the APP, the device will check whether the verification code input by the user is correct after inputting, if the user inputs the verification code incorrectly or the verification is failed when the verification code is not input within 30 seconds. The device will actively report the verification failure message to the APP while the device exits the binding mode.

Through steps S522-S528, after receiving the message that the verification code verification is successful, the Server end verifies the information, including the information carried by the APP when the APP initiates the binding request, and replies the verification result to the intelligent door lock. The Server returns the following information to the intelligent door lock and the APP: service key, bluetooth key, authentication code.

The intelligent door replies an ACK message after receiving an authentication result of the Server, the APP sends the message to the Server by calling HTTPS, the Server gives a Bluetooth key in a response of an HTTPS interface, and the APP sends the Bluetooth key to the intelligent door after receiving the response and simultaneously stores the key in an APP memory for subsequent communication;

after the intelligent door receives the Bluetooth key, the intelligent door can reply to the ACK message. The APP sends the message to the Server by calling HTTPS, and the Server gives service key information among response of HTTPS interface. (since the intelligent door lock has the Bluetooth key, the message is an encrypted message), and the APP sends the service key to the intelligent door lock after receiving the response;

after receiving the service key, the intelligent door lock replies an ACK message, the APP calls the Server HTTPS interface to transmit the message to the Server, the Server gives the appId and the authentication code message (the message is a key-encrypted message because the intelligent door lock already has the bluetooth key and the service key) in the response of the HTTPS interface, and the APP sends the message to the intelligent door lock after receiving the response and simultaneously saves the authentication code in the memory, thereby facilitating the subsequent communication, specifically, as shown in steps S530-S552.

In steps S554-S570, after receiving the confirmation message sent by the intelligent door lock to the APP and receiving the authentication code, the APP gives the confirmation message to the Server, and the Server gives the APP a message (tells the APP that the binding condition has been met), that is, the Server issues a binding-enabled instruction, and the APP initiates an account binding flow (carries MAC address information and initiates an HTTPS request to the Server).

By adopting the technical scheme, after the client initiates the binding request, the Server applies for the Bluetooth key and the service key, the Bluetooth key and the service key are encrypted and then the binding data is transmitted, and the Bluetooth key and the service key are changed when the binding request is initiated in sequence, so that the dynamically acquired Bluetooth key and service key are irregular and circulated, and the security of data transmission is provided.

From the description of the above embodiments, it will be clear to a person skilled in the art that the method according to the above embodiments may be implemented by means of software plus the necessary general hardware platform, but of course also by means of hardware, but in many cases the former is a preferred embodiment. Based on such understanding, the technical solution of the present invention may be embodied essentially or in a part contributing to the prior art in the form of a software product stored in a storage medium (e.g. ROM/RAM, magnetic disk, optical disk) comprising several instructions for causing a terminal device (which may be a mobile phone, a computer, a server, or a network device, etc.) to perform the method of the various embodiments of the present invention.
