The inventor further researches and discovers that in order to ensure safety, the information of the door lock can be used for processing the offline control instruction at the mobile phone side, and then when the door lock cannot communicate with the server, the mobile phone issues the offline control instruction to the door lock, so that offline control over the door lock is realized.

Fig. 1 illustrates an exemplary system architecture 100 to which some embodiments of the offline control method for an intelligent device or the offline control apparatus for an intelligent device of the present application may be applied.

As shown in fig. 1, the system architecture 100 may include a terminal 101, a smart device 102, a server 103, and a network 104. Network 104 is the medium used to provide communication links between terminals 101 and server 103. Network 104 may include wireless communication links and the like. And the terminal 101 and the intelligent device 102 communicate with each other through bluetooth or WiFi.

A user may use the terminal 101 to interact with the server 103 via the network 104 to receive or transmit instructions or the like. Various client applications, such as a control application of the smart device 102, may be installed on the terminal 101.

The terminal 101 may be hardware or software. When the terminal 101 is hardware, it may be various electronic devices, including but not limited to electronic devices such as a smart phone, a tablet computer, and a wearable device. When the terminal 101 is software, it can be installed in the electronic devices listed above. It may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services) or as a single piece of software or software module. The embodiment of the present application does not set any limit to the specific type of the electronic device.

The server 103 may be a server that provides various services, such as a backend server that provides support for the smart device 102. The background server may execute a corresponding function in response to receiving the related instruction of the intelligent device 102 forwarded by the terminal 101, or may send the related instruction to the intelligent device 102 through the terminal 101, where the intelligent device 102 executes the corresponding function.

The server may be hardware or software. When the server is hardware, it may be implemented as a distributed server cluster formed by multiple servers, or may be implemented as a single server. When the server is software, it may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.

It should be noted that the offline control methods for the intelligent devices provided in the embodiments of the present application are respectively executed by the intelligent device 102, the terminal 101, and the server 103, and accordingly, the offline control methods for the intelligent devices are respectively set in the intelligent device 102, the terminal 101, and the server 103.

With continued reference to FIG. 2a, a flowchart of one embodiment of an offline control method for the smart device 102 provided herein is shown. The method in this embodiment may be applied to the intelligent device 102, and the method for controlling the intelligent device offline includes the following steps:

step 201: under the condition that data connection is established between the intelligent equipment and the terminal, the intelligent equipment receives an offline control instruction sent by the terminal.

The offline control instruction is obtained by processing the offline control instruction in the terminal by using at least the equipment information of the intelligent equipment. And further, the offline control instruction received by the intelligent equipment is obtained by encrypting the offline control instruction in the terminal by using at least equipment information.

Specifically, the data connection between the smart device and the terminal may be a wireless connection, such as a bluetooth connection. The data connection between the smart device and the terminal may be established with the operation of the offline control received on the terminal. For example, after a user clicks an offline unlocking button on a mobile phone, the mobile phone establishes a data connection with a door lock through bluetooth.

It should be noted that the device information of the smart device may be device address information and/or device serial number information of the smart device, such as Mac and/or sn of the door lock.

The intelligent device can receive an offline control instruction which is sent by the terminal and is obtained by processing at least the device information through wireless connection with the terminal.

Further, under the condition that data connection is established between the intelligent device and the terminal, the terminal applies for a challenge code request to the intelligent device, and then the intelligent device returns challenge code information to the terminal. The challenge code information is used for processing the offline control instruction in the terminal, that is, the terminal can process the offline control instruction in the terminal by using the device information of the intelligent device and the challenge code information returned by the intelligent device, so as to obtain the processed offline control instruction and transmit the processed offline control instruction to the intelligent device.

For example, as shown in fig. 2b, a bluetooth of a door lock is connected in a mobile phone and issues a request for acquiring challenge code to the door lock, and the door lock sends challenge code to the mobile phone, where challenge code is not encrypted in this process. And then, the mobile phone encrypts the data of the offline control instruction by using Mac, sn and challenge code of the door lock to obtain an encrypted offline control instruction and transmits the encrypted offline control instruction to the door lock.

Specifically, the offline control instruction in the terminal is an offline control instruction sent by the server to the terminal when a data connection is established between the terminal and the server. Specifically, the offline control instruction sent by the server may be an offline control instruction obtained by encrypting the offline control instruction in the server by using at least a session key of the smart device, timestamp information, and device information of the smart device.

The session key of the smart device may be a session key determined by a handshake protocol when a data connection is established between the smart device and the server through the terminal, such as pwspeed. The device information of the smart device may include device address information of the smart device, such as a Mac address of the door lock. Based on this, the server can encrypt the offline control instruction generated and stored in the server using the session key, the timestamp information, and the device information, and obtain the offline control instruction that can be sent to the terminal.

Step 202: the intelligent device verifies the received off-line control instruction at least by using the device information of the intelligent device to obtain an instruction verification result.

The device information of the intelligent device is known in the intelligent device, so that after the intelligent device receives the offline control instruction sent by the terminal, the received offline control instruction is verified at least by using the device information of the intelligent device, such as device address information and/or device serial number information, so as to obtain an instruction verification result representing whether the offline control instruction meets the offline control condition.

Before the intelligent device verifies the offline control instruction, the intelligent device firstly decrypts the received offline control instruction by using at least the device information to obtain the decrypted offline control instruction, and then verifies the decrypted offline control instruction.

It should be noted that, whether the offline control condition is satisfied is characterized by: and whether the offline control instruction sent by the terminal is a legal control instruction or not. For example, the offline control condition may be that characters or character strings corresponding to the offline control instruction are consistent in comparison, or the offline control condition may be that an instruction type of the offline control instruction is consistent with a preset type, or the offline control condition may be that an instruction structure of the offline control instruction is consistent with a preset structure, and so on.

Specifically, in this embodiment, the intelligent device may verify the received offline control instruction at least by using the device information of the intelligent device, for example, by comparing the decrypted character strings and instruction types or comparing the instruction structures with the equivalent verification manner, so as to obtain an instruction verification result.

Further, the intelligent device may verify the received offline control instruction together with the device information of the intelligent device and the challenge code information issued by the intelligent device to the terminal, so as to obtain an instruction verification result.

For example, the door lock decrypts an offline unlocking instruction issued by a mobile phone by using Mac, sn and challenge code of the door lock, and then verifies the decrypted offline unlocking instruction, thereby obtaining an instruction verification result.

Step 203: and under the condition that the instruction verification result represents that the offline control instruction meets the offline control condition, the intelligent equipment executes the offline control instruction.

The intelligent device executes the offline control instruction only when the offline control instruction is verified to meet the offline control condition, namely the offline control instruction sent by the terminal is determined to be legal.

Specifically, the offline control instruction may be an instruction for triggering the intelligent device to be turned on offline, an instruction for starting a corresponding function of the intelligent device offline, an instruction for acquiring corresponding data in the intelligent device offline, and the like, so that offline control over the intelligent device can be realized under the condition that the terminal cannot be connected to the server.

For example, after the door lock decrypts and verifies data of an offline unlocking instruction issued by a mobile phone by using Mac, sn and challenge codes of the door lock, if the offline unlocking instruction is verified to be a legal instruction, the door lock executes an unlocking function corresponding to the offline unlocking instruction, namely, opening the door, and if the offline unlocking instruction is verified not to be the legal instruction, the door lock does not execute the unlocking function.

Therefore, the offline control method for the intelligent device provided by the embodiment of the application is not limited by communication connection between the terminal and the server, and even under the condition that communication cannot be performed between the terminal and the server, the intelligent device can receive the offline control instruction sent by the terminal and perform instruction verification by using the device information of the intelligent device, so that the intelligent device can execute the offline control instruction under the condition that the offline control condition is met, and therefore offline control over the intelligent device is achieved.

With continued reference to FIG. 3, a flow diagram of one embodiment of a method for offline control of the smart device 102 in accordance with the present application is shown. The method in this embodiment may be applied to the terminal 101, and the offline control method for an intelligent device includes the following steps:

step 301: and under the condition that data connection is established between the terminal and the server, the terminal receives an offline control instruction sent by the server.

The data connection between the terminal and the server may be a wireless connection, such as a WiFi-based connection or a mobile communication network-based connection. Based on the control command, the terminal stores the received off-line control command.

Specifically, the offline control instruction sent by the server may be an offline control instruction obtained by encrypting the offline control instruction in the server by using at least a session key of the smart device, timestamp information, and device information of the smart device.

Step 302: and under the condition that the data connection is established between the intelligent equipment and the terminal, the terminal processes the offline control instruction in the terminal by using at least the equipment information of the intelligent equipment.

Wherein, the data connection between the intelligent equipment and the terminal can be wireless connection, such as bluetooth connection and the like.

Further, under the condition that data connection is established between the intelligent device and the terminal, the terminal applies for challenge code information to the intelligent device, and then the intelligent device returns the challenge code information to the terminal. The challenge code information is used to process the offline control instruction in the terminal, that is, the terminal may use the device information of the intelligent device and the challenge code information returned by the intelligent device to process the offline control instruction in the terminal.

For example, a bluetooth of a door lock is connected in a mobile phone, a request for acquiring the challenge code is issued to the door lock, the door lock sends the challenge code to the mobile phone, and the challenge code is not encrypted in the process. And then, the mobile phone encrypts the data of the offline control command by using Mac, sn and challenge code of the door lock to obtain the encrypted offline control command.

Step 303: and the terminal sends the processed offline control instruction to the intelligent equipment, so that the intelligent equipment verifies the received offline control instruction at least by using the equipment information of the intelligent equipment to obtain an instruction verification result, and the intelligent equipment executes the offline control instruction under the condition that the instruction verification result represents that the offline control instruction meets the offline control condition.

Therefore, the offline control method for the intelligent device provided by the embodiment of the application is not limited by communication connection between the terminal and the server, and even if the terminal and the server cannot communicate with each other, the intelligent device can receive the offline control instruction sent by the terminal and verify the instruction by using the device information of the intelligent device, so that the intelligent device can execute the offline control instruction under the condition that the offline control condition is met, and the offline control of the intelligent device is realized.

With continued reference to FIG. 4, a flow diagram of one embodiment of a method for offline control of the smart device 102 is shown, in accordance with the present application. The method in this embodiment may be applied to the server 103, and the method for controlling the intelligent device offline includes the following steps:

step 401: and under the condition that data connection is established between the terminal and the server, the server receives an instruction acquisition request sent by the terminal.

The instruction obtaining request may include a request identifier indicating that the terminal needs to obtain the offline control instruction, for example, the instruction of the request includes a specific field or a specific character string to indicate that the terminal needs to obtain the offline control instruction.

Step 402: the server at least utilizes the session key, the timestamp information and the equipment information of the intelligent equipment to process the offline control instruction in the server and sends the processed offline control instruction to the terminal.

After the offline control instruction sent by the server is stored in the terminal, under the condition that data connection is established between the intelligent device and the terminal, the terminal processes the offline control instruction in the terminal by using at least the device information of the intelligent device and sends the processed offline control instruction to the intelligent device, so that the intelligent device verifies the received offline control instruction by using at least the device information of the intelligent device to obtain an instruction verification result, and under the condition that the instruction verification result represents that the offline control instruction meets the offline control condition, the intelligent device executes the offline control instruction.

With continued reference to FIG. 5a, a flow diagram of one embodiment of a method of offline control of a smart device 102 in accordance with the present application is shown. The off-line control method for the intelligent equipment comprises the following steps:

step 501: under the condition that data connection is established between the terminal and the server, the server receives an instruction acquisition request sent by the terminal.

The instruction obtaining request may include a request identifier indicating that an offline control instruction needs to be obtained, where the instruction obtaining request may be generated when a user performs an instruction obtaining operation on an APP of the smart device, where the operation is set on the terminal.

For example, a user opens a door lock on a mobile phone and clicks a control for acquiring an offline control instruction, thereby generating an instruction acquisition request on the mobile phone, and the mobile phone sends the instruction acquisition request to PaaS (Platform as a Service).

Step 502: and the server processes the offline control instruction in the server.

Specifically, in this embodiment, the server may perform encryption processing on the offline control instruction in the server by using at least the session key of the smart device, the timestamp information, and the device information of the smart device.

The session key of the smart device may be a session key determined by a handshake protocol when a data connection is established between the smart device and the server through the terminal, such as pwspeed. The device information of the smart device may include device address information of the smart device, such as a Mac address of the door lock. Based on this, the server can perform encryption processing on the offline control instruction generated and stored in the server using the session key, the timestamp information, and the device information.

For example, paaS encrypts the offline control instruction by using pwviewed, a timestamp, and a Mac of a door lock after receiving an instruction acquisition request sent by a mobile phone.

Step 503: and the server transmits the processed off-line control instruction to the terminal.

The server can transmit the processed offline control instruction to the terminal through a wireless network between the server and the terminal. The processed offline control instruction is an instruction obtained by encrypting the session key, the timestamp information, and the device information.

For example, paaS sends off-line control commands to the mobile phone after encrypting the off-line control commands by using pwspeed, a timestamp and a Mac of the door lock.

The implementation flow of the encryption algorithm for the PaaS to encrypt the offline control instruction is shown in fig. 5 b:

first, converting the Mac address of the door lock into 6 bytes of data, for example, if the Mac address is "8D0002809F06", the conversion into 6 bytes of data is:

{0x8D，0x00，0x02，0x80，0x9F，0x06}。

then, the data is reshaped by using a time stamp (a time stamp in an offline unlocking instruction is used during offline unlocking) of KEY _ TIMESTAMP _ INT issued by PaaS, for example, if the date of issuing is 2018/10/18, the time stamp converted into the second-level is 1539792000, the character string is directly used as 10-byte data, and if the length of the character string is not 10, a '0' character is complemented later.

Then, the Mac and the 16 bytes of the timestamp are AES encrypted using the 16 bytes pwseed of the door lock (only the server and the door lock are stored locally) to obtain an exclusive or key of the 16 bytes, i.e., xor _ key.

And finally, encrypting a plaintext, namely the offline control instruction which is prepared to be issued by the PaaS by using the xor _ key to obtain a ciphertext, namely the offline control instruction encrypted by the PaaS.

Step 504: and under the condition that data connection is established between the terminal and the server, the server receives a Bluetooth acquisition request sent by the terminal.

The bluetooth acquisition request may be generated when the user performs the operation of the bluetooth key on the APP for the smart device set on the terminal.

For example, a user opens a door lock on a mobile phone and clicks a control for acquiring a bluetooth key, so that a bluetooth acquisition request is generated on the mobile phone, and the mobile phone sends the bluetooth acquisition request to PaaS.

Step 505: the server processes the Bluetooth key in the server.

Specifically, in this embodiment, the server may encrypt the bluetooth key in the server by using at least the session key of the smart device, the timestamp information, and the device information of the smart device.

For example, paaS encrypts a bluetooth key blekey in PaaS using pwsee, a timestamp, and Mac of a door lock after receiving a bluetooth acquisition request sent by a mobile phone. Reference may be made in particular to the encryption algorithm in fig. 5 b.

Step 506: and the server transmits the processed Bluetooth key to the terminal.

The server can transmit the processed Bluetooth key to the terminal through a wireless network between the server and the terminal. The processed bluetooth key is obtained by encrypting the session key, the timestamp information, and the device information.

For example, paaS is issued to the handset after encrypting the bluetooth key using pwspeed, a timestamp, and Mac of the door lock.

Step 507: under the condition that data connection is established between the intelligent equipment and the terminal, the terminal sends a challenge code request to the intelligent equipment.

The challenge code request includes a request identifier for representing that the terminal needs to acquire challenge code information. The challenge code request may be generated when the user performs an operation of offline control on the terminal for the application APP of the smart device.

For example, a user opens a door lock on a mobile phone and clicks an "unlock" control, thereby generating a challenge code request on the mobile phone, and the mobile phone sends the challenge code request to the door lock.

Step 508: and the intelligent equipment returns the challenge code information to the terminal.

The intelligent device generates challenge code information and sends the challenge code information to the terminal after receiving a challenge code request sent by the terminal, so that the terminal can process an offline control instruction in the terminal by using the device information of the intelligent device and the challenge code information returned by the intelligent device, and then the processed offline control instruction is obtained and transmitted to the intelligent device.

For example, the door lock sends challenge code to the cell phone, which is not encrypted. And the mobile phone encrypts the data of the off-line control command stored in the mobile phone by using Mac, sn and challenge code of the door lock to obtain an encrypted off-line control command and transmits the encrypted off-line control command to the door lock.

The implementation flow of the encryption algorithm for encrypting the data of the offline control instruction stored in the mobile phone by using Mac, sn and challenge code of the door lock by the mobile phone is shown in fig. 5 c:

{0x8D，0x00，0x02，0x80，0x9F，0x06}。

the last 10 bits of Mac and sn are then grouped into a byte array of 16 bytes in length.

Then, using 16 bytes challenge code of the door lock to carry out AES encryption on 10 bits behind the Mac and the sn to obtain 16 bytes of XOR key, namely xor _ key.

And finally, encrypting a plaintext, namely the offline control instruction to be issued by the mobile phone, by using the xor _ key to obtain a ciphertext, namely the offline control instruction encrypted by the mobile phone.

Step 509: and the terminal sends the offline control instruction to the intelligent equipment.

The offline control instruction received by the intelligent device is the offline control instruction sent by the server to the terminal under the condition that data connection is established between the terminal and the server. Refer specifically to steps 501-503.

Step 510: the intelligent device verifies the received off-line control instruction at least by using the device information of the intelligent device to obtain an instruction verification result.

Specifically, the implementation manner in step 510 may refer to what is described in step 202.

For example, the door lock decrypts data of an offline control instruction issued by a mobile phone by using Mac, sn and challenge code of the door lock, and then performs verification processing, thereby obtaining an instruction verification result.

Step 511: and under the condition that the instruction verification result represents that the offline control instruction meets the offline control condition, the intelligent equipment executes the offline control instruction.

For example, after the data of the offline control instruction issued by the mobile phone is decrypted and verified by using Mac, sn and challenge code of the door lock, if the offline control instruction is verified to be a legal instruction, the door lock executes an unlocking function corresponding to the offline control instruction, that is, opens the door, and if the offline control instruction is verified not to be a legal instruction, the door lock does not execute the unlocking function.

In a specific implementation, in step 202 shown in fig. 2a, when the smart device verifies the received offline control instruction, an instruction verification result may be obtained in the following manner, as shown in fig. 6 a:

step 601: the intelligent device analyzes a first character string contained in the offline control instruction by using at least device information of the intelligent device.

Specifically, in this embodiment, the device information and the timestamp information of the smart device and the bluetooth key in the smart device may be used to parse the first character string included in the offline control instruction. For example, the token in the offline unlocking command is encrypted by the Mac and the timestamp of the door lock used by the door lock and the blekey of the door lock, so that the door lock analyzes the token in the offline control command issued by the mobile phone by using the Mac and the timestamp of the door lock and the blekey of the door lock to obtain the first character string, such as the token, included in the offline control command.

The implementation flow of the encryption algorithm for the door lock to encrypt the token by using the Mac and the timestamp of the door lock and the blekey of the door lock is shown in fig. 6 b:

{0x8D，0x00，0x02，0x80，0x9F，0x06}。

then, the data is reshaped by using the timestamp of KEY _ TIMESTAMP _ INT issued by PaaS (the timestamp in the offline unlocking instruction is used during offline unlocking), and converted into a character string, for example, if the current day of issuing is 2018/10/18, the timestamp converted into the second grade is 1539792000, the character string is directly used as 10-byte data, and if the length of the character string is not enough 10, the '0' character is complemented later.

Then, the Mac and the 16 bytes of the timestamp are AES encrypted using the 16 bytes blekey of the door lock (only the server and the door lock are locally stored), and an exclusive or key of the 16 bytes, that is, xor _ key, is obtained.

And finally, encrypting the plaintext, namely the token in the offline unlocking instruction by using the xor _ key to obtain the ciphertext, namely the encrypted token.

It should be noted that the bluetooth key in the intelligent device is sent to the intelligent device by the terminal after being issued to the terminal by the server.

After the smart device receives the bluetooth key, the bluetooth key is obtained by the server performing encryption processing using the session key, the timestamp information, and the device information of the smart device. Therefore, before the smart device uses the bluetooth key, the smart device first decrypts the session key of the smart device using the device information and the timestamp information of the smart device, and based on this, the smart device analyzes the offline control command using the device information and the timestamp information of the smart device and the decrypted bluetooth key, and analyzes the first character string included in the offline control command.

In addition, since the offline control instruction received by the smart device is obtained by performing primary encryption on the session key and the timestamp information of the smart device by the server and performing secondary encryption on the device information of the smart device by the terminal, the decrypted offline control instruction needs to be decrypted again by using the session key and the timestamp information of the smart device after the offline control instruction is decrypted for the first time by using at least the device information of the smart device, and the offline control instruction subjected to the secondary decryption can be analyzed by using the device information and the timestamp information of the smart device and the decrypted bluetooth key of the smart device by the smart device, so that the first character string contained in the offline control instruction can be analyzed.

For example, after the door lock decrypts the offline unlocking instruction issued by the mobile phone by using Mac, sn and the challenge code of the door lock, the pwread, the timestamp and Mac of the door lock are used to decrypt the decrypted offline unlocking instruction again, and at this time, the decrypted offline unlocking instruction is analyzed by using Mac and the timestamp of the door lock and blekey of the door lock by the door lock, so as to obtain a first character string, such as token, included in the offline control instruction.

Step 602: the intelligent device determines whether the first character string matches a second character string stored in the intelligent device, if the first character string matches the second character string, step 603 is executed, and if the first character string does not match the second character string, step 604 is executed.

Step 603: and the intelligent equipment generates an instruction verification result representing that the offline control instruction meets the offline control instruction.

Step 604: and the intelligent equipment generates an instruction verification result representing that the offline control instruction does not meet the offline control instruction.

That is to say, under the condition that the first character string is matched with the second character string, the obtained instruction verification result represents that the offline control instruction meets the offline control condition, and under the condition that the first character string is not matched with the second character string, the obtained instruction verification result represents that the offline control instruction does not meet the offline control condition.

In a specific implementation, the first character string is a token character string in the offline control instruction, and specifically may be a character string obtained by encrypting a preset fixed character string by using a bluetooth key; the second character string is a fixed character string stored in the intelligent device. Therefore, in this embodiment, the matching of the first character string and the second character string means: the character string obtained by encrypting the second character string by using the Bluetooth key is consistent with the first character string; or, the matching of the first character string and the second character string means: and the character string obtained by decrypting the first character string by using the Bluetooth key is consistent with the second character string. Therefore, under the condition that the instruction verification result represents that the offline control instruction meets the offline control condition, namely under the condition that the first character string is matched with the second character string, the intelligent device executes the offline control instruction.

For example, the door lock encrypts the fixed character string "123456" by using blekey, and compares the obtained character string with the analyzed token; or the door lock decrypts the analyzed token by using blekey, compares the obtained character string with the fixed character string '123456', and the comparison result represents whether the offline control instruction meets the offline control condition.

With reference to the scheme shown in fig. 6, before step 601, the method in this embodiment may further include the following steps, as shown in fig. 7:

step 605: whether the intelligent equipment checks that the off-line control is effective or not can be specifically as follows: the intelligent device judges whether the survival time of the offline control instruction exceeds a preset first target time length, executes step 604 under the condition that the survival time of the offline control instruction exceeds the first target time length, namely the survival time of the offline control instruction is effective, and executes step 601 under the condition that the survival time of the offline control instruction does not exceed the first target time length.

And timing is started after the offline control instruction is received by the intelligent equipment, and the time length obtained by timing is the survival time length of the offline control instruction.

That is to say, before analyzing the received offline control instruction, the intelligent device verifies whether the offline control instruction is expired or not, if not, the intelligent device continues to execute a subsequent verification process, and if so, the intelligent device can directly generate an instruction verification result that the offline control instruction does not satisfy the offline control condition.

For example, the door lock judges whether an offline unlocking instruction issued by the mobile phone is overdue or not, if so, the door lock does not execute the offline unlocking instruction, and if not, the door lock performs an instruction verification process aiming at the offline unlocking instruction.

Continuing with the flow shown in fig. 7, before step 601, the method in this embodiment may further include the following steps, as shown in fig. 8:

step 606: whether the intelligent equipment judges the stored Bluetooth key is effective or not can be specifically: the intelligent device judges whether the intelligent device stores a Bluetooth key or not, executes step 604 if the intelligent device does not store the Bluetooth key or the survival time of the Bluetooth key stored in the intelligent device is greater than or equal to a preset second target time, and executes step 601 if the survival time of the Bluetooth key stored in the intelligent device is less than the second target time. Of course, step 605 is performed before step 601 is performed.

Therefore, only under the condition that the survival time of the bluetooth key stored in the intelligent device does not exceed the second target time length, the intelligent device can use the device information of the intelligent device and the bluetooth key in the intelligent device, and further can analyze the first character string contained in the offline control command by combining the timestamp information.

And timing is started after the Bluetooth key is received by the intelligent equipment, and the duration obtained by timing is the survival duration of the Bluetooth key.

For example, the door lock determines whether the door lock stores blekey, if the blekey is stored, determines whether the blekey exceeds the validity period, if the blekey exceeds 24 hours, the validity period is a time obtained by extending the time when the blekey is stored by the door lock by the corresponding validity period, if the blekey exceeds the validity period, the door lock generates a result that the verification of the offline unlocking instruction fails, and if the blekey does not exceed the validity period, the door lock continues to perform instruction verification on the offline unlocking instruction according to the description in the foregoing text.

Continuing with the flow shown in fig. 8, in step 606, when it is determined that the bluetooth key is not stored in the smart device or the lifetime of the bluetooth key stored in the smart device is greater than or equal to the second target duration, the method in this embodiment may further include the following steps, as shown in fig. 9:

step 607: and the intelligent device sends a notice message of the expiration of the Bluetooth key to the terminal so that the terminal can read the Bluetooth key again in the storage area.

For example, the door lock sends a message to the cell phone that the blekey expires. The mobile phone reads the blekey again in the mobile phone memory.

Step 608: the intelligent device receives the Bluetooth key sent by the terminal.

The bluetooth key received by the intelligent device at this time is the bluetooth key which is read by the terminal from the bluetooth key stored in the terminal again and sent to the intelligent device. The bluetooth key read by the terminal again may be a fixed bluetooth key, that is, the server does not send the terminal again after sending the bluetooth key once. That is, the server encrypts the bluetooth key using the device information of the smart device, the timestamp information, and the session key of the smart device and transmits the encrypted bluetooth key to the terminal when a data connection is established between the server and the terminal. Or, the bluetooth key read again by the terminal may also be a bluetooth key updated regularly. That is, the server periodically encrypts the bluetooth key using the device information of the smart device, the timestamp information, and the session key of the smart device, and periodically transmits the encrypted bluetooth key to the terminal when a data connection is established between the server and the terminal.

At this time, the lifetime of the bluetooth key received by the smart device is less than the second target duration.

For example, the door lock receives the blekey re-issued by the terminal.

Step 609: the smart device decrypts the received bluetooth key using at least the device information of the smart device.

Specifically, the smart device may decrypt the bluetooth key sent from the terminal using the device information of the smart device, the timestamp information, and the session key of the smart device.

For example, the door lock decrypts the blekey sent from the mobile phone using the door lock's Mac, timestamp, and pwsee.

Step 610: and the intelligent equipment stores the decrypted Bluetooth key.

Specifically, the smart device records the lifetime of the bluetooth key while storing the decrypted bluetooth key.

For example, the door lock stores the decrypted blekey, and records the validity period of the blekey stored by the door lock, where the validity period is the time when the blekey is stored and is corresponding to the time when the second target duration is extended.

Step 611: the intelligent device transmits the first message to the terminal to trigger the terminal to send the off-line control instruction to the intelligent device again.

That is to say, after the smart device successfully adds the valid bluetooth key, the terminal is notified, the terminal processes the offline control instruction stored by the terminal again by using at least the device information of the smart device and transmits the offline control instruction to the smart device, so that the smart device determines whether to execute the offline control instruction after verifying the offline control instruction according to the instruction verification process in the foregoing.

For example, the door lock sends a message of "successful addition" to the mobile phone, and the mobile phone reuses Mac and sn of the door lock and challenge code information to encrypt an offline unlocking instruction sent by a server stored in the mobile phone and send the offline unlocking instruction to the door lock under the condition that the message represents that the bluetooth key is successfully added, so that the door lock verifies the offline unlocking instruction again.

With reference to the flow shown in fig. 2a, after the intelligent device executes the offline control instruction, the method in this embodiment may further include the following steps, as shown in fig. 10:

step 204: and the intelligent equipment receives an electric quantity acquisition instruction sent by the terminal.

The electric quantity obtaining instruction can be generated after the terminal user performs click operation of electric quantity obtaining on the input component of the terminal user, or can be automatically generated when the terminal needs to use the electric quantity parameter.

For example, when the user clicks a button "acquire remaining power" on the mobile phone, the mobile phone generates a power acquisition command and transmits the power acquisition command to the door lock.

Step 205: and the intelligent equipment transmits the current electric quantity parameter of the intelligent equipment to the terminal.

And the current electric quantity parameter is used for executing a corresponding battery processing instruction. For example, when the remaining electric quantity value in the current electric quantity parameter is lower than the threshold value, the terminal outputs prompt information of low electric quantity for the user, or the terminal generates an automatic charging instruction and sends the charging instruction to the intelligent device, and the intelligent device triggers an automatic charging process to realize automatic charging control.

For example, after receiving the residual electric quantity read by the door lock, the mobile phone judges whether the residual electric quantity is less than 4.8V, if so, a low light on the door lock is controlled to flash, or a specific area output on the mobile phone is controlled to change so as to prompt a user of a low electric quantity state, otherwise, the door lock reports a motor unlocking event after unlocking.

In specific implementation, the method in this embodiment not only can implement offline control on the intelligent device, but also can provide online control on the intelligent device for the user. Specifically, the intelligent device outputs online control prompt information under the condition that data connection is established between the terminal and the server, and the online control prompt information is used for prompting online control under the condition that data connection is established between the terminal and the server.

For example, when the door lock monitors that data connection is established between the mobile phone and the PaaS, the door lock outputs prompt information for a user to prompt the user to perform unlocking control and other control on the door lock in an online manner.

Taking the case that the mobile phone unlocks the door lock in an online manner, the control flow of issuing the online bluetooth key and opening the door online is briefly described as follows, as shown in fig. 11:

under the condition that the mobile phone AP can establish data connection with PaaS, after receiving an unlocking operation clicked by a user on the mobile phone, the mobile phone is connected with the Bluetooth of the door lock and issues a message for acquiring the challenge code, and the challenge code generated by the door lock is sent to the mobile phone without encryption;

the mobile phone requests PaaS to acquire a secret key sessionkey, paaS issues the sessionkey to the mobile phone, the mobile phone issues the sessionkey to the door lock, and the door lock decrypts the sessionkey by using challenge code and a session secret key pwseed of the door lock and replies an ack message to the mobile phone;

the method comprises the steps that a mobile phone requests a PaaS to acquire a Bluetooth key, the PaaS issues the Bluetooth key to the mobile phone, then the mobile phone issues an online door opening instruction, a door lock analyzes the online door opening instruction by using sessionkey and changechange code, when the Bluetooth key exists and is effective, a token in the online door opening instruction is analyzed by using blekey and changechange code, if the token represents that the online door opening instruction is verified successfully, the door lock executes a door opening action, and a message of door opening success and a door opening event occurrence is sent to the mobile phone; if the token represents that the online door opening instruction is failed to verify, the door lock sends a door opening failure message to the mobile phone, the mobile phone can also receive a message that the door opening is unsuccessful under the condition that the Bluetooth key does not exist, at the moment, the mobile phone issues the Bluetooth key to the door lock again, the door lock analyzes the Bluetooth key by using sessionkey and challenge code and stores the Bluetooth key, namely blekey, then the door lock sends an adding success message to the mobile phone, and after the mobile phone determines that the adding is successful, the online door opening instruction is issued to the door lock again, so that the door lock conducts online door opening verification again.

In addition, the bluetooth key may be modified or deleted.
