In this process, the door lock token is first sent to the client by the smart door lock through the second communication connection, and then the first communication connection is used. Sent by the client to the server.

Step 410, the server receives the door lock token.

This process is the process in which the server receives the door lock token from the client through the first communication connection.

Step 411, the server performs matching verification between the client and the smart door lock through the door lock token.

Optionally, the server decrypts the door lock token correspondingly, and determines the correspondence between the client and the smart door lock from the decrypted information contained in the door lock token, so as to perform matching verification between the client and the smart door lock. .

Step 412, the server determines the control binding relationship between the client and the smart door lock in response to the matching verification being passed.

In one example, the server verifies the client identification and the door lock identification in the door lock token with the client identification and the door lock identification pre-stored by itself, and confirms their correctness. The control binding relationship between door locks.

After the control binding relationship is established, the client can control the smart door lock through the control interface. Referring to FIG. 6 , the control interface 600 is an interface for controlling the smart door lock 610 after the client and the smart door lock 610 have established a control binding relationship. In the control area 611, an unlocking control 6111, a locking control 6112 and an unbinding control 6113 are included. Through the unlocking control 6111, the client can switch the smart door lock to the unlocked state; through the locking control 6112, the client can switch the smart door lock to the locked state; through the unbinding control 6113, the client can unbind the smart door lock Certainly.

To sum up, in the method provided in this embodiment, the client receives a client token that indicates matching verification between the client and the smart door lock, and forwards the token to the smart door lock. The door lock token is obtained, and then the control binding relationship between the client and the smart door lock is determined according to the matching result of the server, which realizes that on the basis of the client token as the credential, the client, the server and the smart door lock can The knowledge and verification of the binding process information improves the security of the binding between the client and the smart door lock.

For smart door locks, after receiving the client token and knowing the conditions for establishing a control and binding relationship with the client, the client forwards the door lock token to the server, so that the server uses the door lock token as the certificate, Confirm that the verification between the client and the smart door lock has been completed, so as to realize the knowledge and verification of the binding process information between the client, the server and the smart door lock, and improve the security of the binding between the client and the smart door lock. sex.

That is, the method provided in this embodiment enables the client, the server and the smart door lock to know the binding process information, and confirms it through the door lock token, which improves the binding between the client and the smart door lock. time security.

During the establishment of the control binding relationship between the client and the smart door lock, the identity of the client and the smart door lock can be further verified by matching the identifier and the key. Fig. 7 shows the schematic flow chart of the control method of a kind of intelligent door lock provided by an exemplary embodiment of the present application, and this process can replace after step 408 as shown in Fig. 4, this method comprises:

Step 701, the smart door lock sends the first door lock key and the door lock identifier to the server.

In this embodiment, the door lock corresponds to a door lock key and a door lock identifier. The door lock key includes a first door lock key and a second door lock key. Among them, the first door lock key is the original identifier of the smart door lock, that is, the door lock identifier that is burned into the smart door lock when the smart door lock is produced and stored in the server. The second door lock key is a temporary key generated by the server for the client. In one example, when the temporary key room server receives the door lock identification, it generates a key for the smart door lock; in another example, the temporary key is the distribution network between the client and the smart door lock received by the server. The key generated after the information. This application does not limit the generation time of the second door lock key, and the second door lock key is the key generated after the server receives the network distribution information between the client and the smart door lock as an example for description.

Optionally, step 701 is implemented after step 408 as shown in FIG. 4 ; or, step 701 is implemented before step 401 as shown in FIG. 4 .

Step 702, the server receives the first door lock key and the door lock identifier.

Optionally, the door lock broadcasts the first door lock key and the door lock identification in the form of broadcast, and sets the key in the protocol header of the broadcast, so that the server needs to decrypt the key when receiving the broadcast. , to obtain the first door lock key and door lock ID.

Step 703, the server determines the second door lock key according to the door lock identifier.

After receiving the door lock identification, the server generates a second door lock key; or, after receiving the door lock identification, the server obtains the second door lock key from a list stored by the server.

Step 704, the client sends the first client identifier and the door lock token to the server.

In the embodiment of the present application, in the process of forwarding the door lock token, the client also synchronously forwards the client identifier that uniquely indicates the client.

The first client identifier is an identifier that uniquely indicates the client. The binding request also includes the first client identifier. The door lock token also includes a second client identifier, and the second client identifier is the client identifier included in the client token, that is, the second client identifier is determined by the server according to the client that sent the binding request Client ID. In a normal verification process, the first client identification and the second client identification should be the same.

The encryption of the client token by the smart door lock is encrypted by the first door lock key. After obtaining the door lock token, the smart door lock forwards the first client identification and the door lock token to the server together.

In one example, the smart door lock also transmits the door lock identification synchronously.

Step 705, the service receives the first client identification and the door lock token.

In one example, the smart door lock also receives the door lock identification synchronously.

Step 706, the server determines the second door lock key by using the door lock identifier.

In one example, the door lock token includes a door lock identifier displayed in plain text, and the server can directly determine the corresponding second door lock key through the door lock identifier; in another example, the server receives the transmission from the smart door lock synchronously. the door lock identification, and determine the second door lock key according to the door lock identification.

Step 707, the server decrypts the door lock token through the second door lock key to obtain the second client identification.

In this embodiment of the present application, the second door lock key of the smart door lock can be used to decrypt the data encrypted by the first door lock key. Since the second door lock key is only stored by the server, the smart door lock cannot The second door lock key is known, so the smart door lock intelligently encrypts the client token through the first door lock key. And in the decryption process, the server can decrypt the door lock token by instructing the unified intelligent door lock, that is, through the second door lock key corresponding to the same door lock identification, to obtain the second client identification.

Step 708: The server compares the first client identifier with the second client identifier.

When passing the verification, the server is required to determine that the first client identifier is the same as the client indicated by the second client identifier. Therefore, in an example, the server compares the characters in the first client identifier with the characters in the second client identifier. Compare one by one.

Step 709, the server determines that the matching verification is passed in response to the first client identifier matching the second client identifier.

As shown in the above step 708, when the server determines that each character in the first client identifier is the same as each character in the second client identifier, it can determine that the matching verification is passed.

To sum up, in the method provided in this embodiment, the client receives a client token that indicates matching verification between the client and the smart door lock, and forwards the token to the smart door lock. The door lock token is obtained, and then the control binding relationship between the client and the smart door lock is determined according to the matching result of the server, which realizes that on the basis of the client token as the credential, the client, the server and the smart door lock can The knowledge and verification of the binding process information improves the security of the binding between the client and the smart door lock.

For smart door locks, after receiving the client token and knowing the conditions for establishing a control and binding relationship with the client, the client forwards the door lock token to the server, so that the server uses the door lock token as the certificate, Confirm that the verification between the client and the smart door lock has been completed, so as to realize the knowledge and verification of the binding process information between the client, the server and the smart door lock, and improve the security of the binding between the client and the smart door lock. sex.

The connection between the server and the client is verified by a match between the first client identifier sent by the client and the second client identifier included in the client token, even if the server determines the client that sent the binding request Whether the client that actually needs to be bound is the same client, improves the security when binding between the client and the smart door lock.

Through the setting of the first door lock key and the second door lock key, the server can synchronously confirm the identity of the smart door lock in the process of obtaining the second client identification, so as to complete the two-way communication between the smart door lock and the server. The verification further improves the security of the binding between the client and the smart door lock.

In an embodiment of the present application, the client that has established a control binding relationship with the smart door lock has authority distinction, and the client with high authority can control the client with low authority on its control interface. Fig. 8 shows the schematic flow chart of the control method of a kind of smart door lock provided by an exemplary embodiment of the present application, and is described by taking the method applied to the control system of the smart door lock as an example, and the method includes:

Step 801, the smart door lock sends the first door lock key and the door lock identifier to the server.

Before step 801 is executed, a distribution network connection is established between the client and the smart door lock.

After the distribution network connection is established between the smart door lock and the client, the smart door lock sends the first door lock key and the door lock ID to the server through the transparent transmission of the client.

Step 802, the server receives the first door lock key and the door lock identifier.

This step is the same as step 702 and will not be repeated here. And at this time, the server generates the second door lock key according to the first door lock key and the door lock identifier.

In this embodiment, steps 801 to 802 are performed after the network configuration process is completed and before the server receives the binding request.

Step 803, the client sends a binding request to the server.

The binding request is used to request the establishment of a control binding relationship between the client and the smart door lock when the customer order and the smart door lock have established a distribution network connection. In this embodiment, a single binding request is used to request to establish a control binding relationship between a client and a smart door lock.

Step 804, the server receives the binding request sent by the client.

In this embodiment, the server is implemented as a cloud server, and the server has saved the network distribution settings between the client and the smart door lock.

Step 805, the server determines the current state of the smart door lock.

The current state of the smart door lock includes the unbound state and the bound state. The unbound state is the state in which the smart door lock has not established a control binding relationship with the client. Optionally, at this time, no distribution network connection has been established between the smart door lock and the client; the binding state is The smart door lock is connected to the customer list for distribution network, and/or, the state of a control binding relationship is established with the client. The server judges the current state of the smart door lock according to the data about the smart door lock stored by itself: when the current state of the smart door lock is an unbound state, the server only stores the door lock identifier of the smart door lock and the first door lock. lock key; or, any data about the smart door lock stored in the server. In this embodiment, when the current state of the smart door lock is an unbound state, the server stores the door lock identifier and the first door lock key of the smart door lock as an example for description.

In one example, the smart door lock includes a factory reset button, and the factory reset button is implemented as a physical button. Through the operation of the reset button, the smart door lock can be restored to the unbound state. At this time, the smart door lock sends an instruction to restore the unbound state to the server, and the server deletes the data related to the binding relationship of the smart door lock stored in the server according to the instruction. After deletion, only the door lock ID of the smart door lock and the first door lock key are stored in the server.

In the above example, specifically, the smart door lock sends historical binding information through the client, and the historical binding information is used to indicate the history of binding with the smart door lock before the client is bound with the smart door lock client information. After receiving the historical binding information, when the client has administrator authority, it can send a binding release instruction to the server, and the binding release instruction is used to instruct the server to release the control binding relationship between the historical client and the smart door lock. , when the server receives the binding release instruction, it releases the corresponding control binding relationship, so that the smart door lock is restored to the unbound state at this time.

Step 806, the server determines that the client has the administrator authority of the smart door lock in response to the current state being the unbound state and receiving the binding request.

Clients that establish a control binding relationship with the smart door lock have different permissions, including administrator permissions and ordinary permissions. Among all the clients that have established a control binding relationship with the smart door lock, only one client has administrator rights, and the rest have ordinary rights. Clients with administrator privileges can manage clients with common privileges, including saving the client IDs corresponding to clients with common privileges.

Referring to FIG. 9, in the control interface 900 with administrator authority, in addition to the unlocking control 911, the locking control 912 and the unbinding control 913 for controlling the smart door lock, it also includes a client display area 914 for ordinary authority, in In this display area, the common authority client identification 9141, the common authority client identification 9142, the common authority client identification 9143 and the common authority client identification 9144 that have a control binding relationship with the smart door lock can be displayed. The operation of the authorization client identification can further control the ordinary authorization client. In the control interface with ordinary permissions, only the unlocking control, the locking control and the unbinding control are included.

In addition, in the embodiment of the present application, when the current state of the server is a bound state and a binding request is received, it is determined that the client has the management authority of an ordinary user; or, when the current state of the server is a bound state, And when a binding request is received, the client's binding request is rejected.

Step 807, the server saves the first client identifier corresponding to the client.

After determining that the client has administrator authority, the server saves the first client identifier corresponding to the client. When receiving a subsequently sent binding request, the server sends the binding request to the client according to the first client identifier, and the client determines whether the binding request is passed.

Step 808, the server generates a client token according to the binding request.

When generating the client token according to the binding request, the server stores the acquired first client identifier in the client token as the second client identifier.

Step 809, the server sends the client token and the timer to the client.

A timer is generated by the server in response to sending a client token and is used to limit how long the client token is valid. In the process of realizing the synchronous timing between the server and the smart door lock, the server sends the timer to the smart door lock through the client to verify the validity of the client token.

Step 810, the client receives the client token and the timer.

In one example, the timer is packaged in the client token and sent by the server to the client.

Step 811, the client sends the client token and the timer to the smart door lock.

In this embodiment, the client and the smart door lock have already been connected to the network distribution network, so the client can directly send the client token to the smart door lock through the second communication connection with the smart door lock.

Step 812, the smart door lock receives the client token and the timer.

After the smart door lock receives the timer, the smart door lock synchronizes with the server through the timer instantly to verify whether the client token has expired.

Step 813, the smart door lock encrypts the client token with the first door lock key to obtain a door lock token.

When the timer is packaged in the client token, the smart door lock first needs to obtain the timer from the client token, and then encrypt other parts of the client token to obtain the door lock token.

Step 814, the smart door lock sends the door lock token to the client.

This process is the process in which the smart door lock forwards the door lock token to the server through the client.

Step 815, the client receives the door lock token.

After the client receives the door lock token, it will additionally obtain the first client identifier corresponding to itself.

Step 816, the client sends the first client identifier and the door lock token to the server.

Step 817, the server receives the first client identifier and the door lock token.

In one example, the verification step may be skipped when the server confirms that the first client identification indicates that the client has administrator rights.

Step 818, the server decrypts the door lock token through the second door lock key to obtain the second client identification.

The second door lock key corresponds to the first door lock key, and both can decrypt the door lock token.

Step 819, the server compares the first client identifier with the second client identifier.

As shown in step 707, the server determines that the first client identification and the second client identification are identical, i.e., each character is the same.

Step 820, the server determines that the matching verification is passed in response to the first client identification being the same as the second client identification.

When a timer is stored in the server and the smart door lock, it is necessary to determine that the first client identification and the second client identification are the same within the time limited by the timer, so as to determine that the matching verification is passed.

Step 821, the server determines the control binding relationship between the client and the smart door lock.

After the control binding relationship is established between the client and the smart door lock, optionally, the control interface of the client displays that the control binding relationship is established successfully, and the smart door lock prompts the control binding relationship to be established successfully by means of a prompt sound.

To sum up, in the method provided in this embodiment, the client receives a client token that indicates matching verification between the client and the smart door lock, and forwards the token to the smart door lock. The door lock token is obtained, and then the control binding relationship between the client and the smart door lock is determined according to the matching result of the server, which realizes that on the basis of the client token as the credential, the client, the server and the smart door lock can The knowledge and verification of the binding process information improves the security of the binding between the client and the smart door lock.

For smart door locks, after receiving the client token and knowing the conditions for establishing a control and binding relationship with the client, the client forwards the door lock token to the server, so that the server uses the door lock token as the certificate, Confirm that the verification between the client and the smart door lock has been completed, so as to realize the knowledge and verification of the binding process information between the client, the server and the smart door lock, and improve the security of the binding between the client and the smart door lock. sex.

Before the verification process between the client and the smart door lock, the distribution network is verified first, and the distribution network connection is established, so that the data in the connection process does not need to be sent in the form of broadcast, which improves the confidentiality and security of the connection process.

By setting the administrator authority and common authority, the client with administrator authority can actively manage other clients, and the authentication method is convenient and the operation method is simple, which further improves the connection efficiency.

By setting the timer, the verification process is time-sensitive, which further improves the confidentiality and security of the connection process.

Through the sending of historical binding information by the smart door lock, the client with administrator authority can receive the information of the smart door lock, and then the client can determine whether to retain the historical binding information to prevent information redundancy in the smart door lock.

Step 1003, the client sends a request for obtaining the device name to the smart door lock.

This process is that the client sends a request to the smart door lock to obtain the information of the smart door lock before connecting to the distribution network.

Step 1004, the smart door lock sends the door lock identifier and the first door lock key to the client.

By sending the door lock ID and the first door lock key, the identity of the smart door lock and the client is confirmed, and the client confirms the identity of the smart door lock.

Step 1005, the client sends the first client identifier, the current state of the smart door lock, the door lock identifier and the first door lock key to the server.

Among them, the door lock identification and the first door lock key are the data sent by the smart door lock to the server and forwarded by the client.

Step 1006, the server generates a second door lock key, a counter and a client token.

The client token includes a second client identifier, random data and a counter. The random data is the main content in the client token, which is used for subsequent verification.

Step 1007, the server sends the timer and the client token to the client.

Optionally, when sending the timer and the client token, the server also sends temporary data together.

Step 1008, the client sends the first client identifier and the client token to the smart door lock.

This process is the process of forwarding the client token from the client to the server.

Step 1009, the smart door lock sends the door lock token and the encrypted client identifier to the client.

In this process, the smart door lock encrypts the first door lock token and the client ID through the first door lock key, and sends it to the client.

Step 1010, the client forwards the door lock token and the first client identifier to the server.

The client acts as a relay to transparently transmit the door lock token and the first client identifier to the server.

Step 1011, the server decrypts the door lock token with the first door lock key corresponding to the door lock identification to obtain the client token, and then decrypts the client token with the second door lock key corresponding to the door lock identification to obtain the second client logo.

In this embodiment, the server needs to perform authentication between the client and the smart door lock through the comparison between the first client identification and the second client identification.

Step 1012, the timer starts counting.

Optionally, in this embodiment, the timer is used to time the control binding relationship between the client and the smart door lock.

Step 1013, the smart door lock notifies the client that the binding is successful.

This process is the process of confirming the establishment of a control binding relationship between the client and the smart door lock.

In the case of establishing a control binding relationship, the client will read the firmware version number of the smart door lock and upload it to the server for subsequent hardware firmware updates.
