Referring to fig. 2, fig. 2 is a block diagram illustrating a hardware structure of an intelligent door lock according to an exemplary embodiment. It should be noted that the intelligent door lock is only an example adapted to the present invention, and should not be considered as providing any limitation to the scope of the present invention. Nor should the intelligent door lock be interpreted as requiring reliance on, or necessity of, one or more of the components of the exemplary intelligent door lock illustrated in fig. 2.

These components communicate with each other via one or more communication buses or signal lines.
The microprocessor 401 is used as a core module of data processing of the intelligent door lock, and is used for calculating data stored in the memory 402 of the intelligent door lock.
The memory 402 is also used for storing computer readable instructions and modules, such as computer readable instructions and modules corresponding to the intelligent door lock wireless communication method and system in the exemplary embodiment of the present invention, and the processor 401 executes the computer readable instructions stored in the memory 402, thereby performing various functions and data processing, i.e., completing the intelligent door lock wireless communication method.

It will be appreciated that the configuration shown in fig. 2 is merely illustrative and that the smart door lock may include more or fewer components than shown in fig. 2, or different components than shown in fig. 2. The components shown in fig. 2 may be implemented in hardware, software, or a combination thereof.
Fig. 3 is a flowchart illustrating an intelligent door lock wireless communication method according to an exemplary embodiment, which is suitable for the intelligent door lock shown in the implementation environment of fig. 1, and the hardware structure of the intelligent door lock is as shown in fig. 2.
The intelligent door lock wireless communication method is executed by the intelligent door lock and can comprise the following steps:
in step 110, control instruction data forwarded by the gateway is received, where the control instruction data is obtained by encrypting, by the gateway, a control instruction generated by the client according to the user trigger operation.
The user triggering operation is that the user triggers the operation in the client interface. The operation of the user triggering the client interface can enable the client to generate a corresponding control instruction, and the control instruction is used for controlling the intelligent door lock to execute the corresponding operation. For example, in one embodiment, the client-side interface adds an unlocking user addition entry to the user, and if the user wishes to add a new unlocking user, the user addition entry in the client-side interface triggers an "add unlocking user" operation, so that the intelligent door lock learns that the user wishes to add the new unlocking user, and further generates an "add unlocking user" control instruction accordingly.
Certainly, in other embodiments, the control instruction generated by the client in response to the user trigger operation may further include a "delete unlock user" control instruction, a "synchronize unlock user" control instruction, a "set temporary unlock password" control instruction, a "set user sign-in password" control instruction, an "intelligent door lock unlock record acquisition" control instruction, and the like, where a specific type of the control instruction is not limited, and accordingly, the intelligent door lock wireless communication method provided in this embodiment is applicable to different application scenarios according to the type of the control instruction, for example, the "add unlock user" control instruction corresponds to a fingerprint addition application scenario, and the "intelligent door lock unlock record acquisition" control instruction corresponds to an unlock behavior acquisition application scenario.
For the gateway, after the client generates a control instruction according to the user triggering operation and sends the generated control instruction to the gateway, the gateway can receive the control instruction sent by the client and encrypt the control instruction, so that the security of wireless communication between the gateway and the intelligent door lock is ensured.
Specifically, the control instruction is firstly encrypted for the first time according to an encryption algorithm configured in a specified communication protocol to obtain encrypted data, and then the encrypted data is encrypted for the second time according to a symmetric encryption algorithm to obtain control instruction data.
Therefore, for the intelligent door lock, after the gateway encrypts the control command sent by the client twice to obtain the control command data, the gateway can receive the control command data sent by the gateway.
Furthermore, the intelligent door lock and the gateway are respectively provided with a communication module, so that the intelligent door lock and the gateway are respectively connected with each other through a wireless or wired network according to a specified communication protocol supported by the communication module, and further, the communication between the intelligent door lock and the gateway is realized through the network connection.
The designated communication protocol can be any one of a ZigBee protocol, a Bluetooth protocol and a WiFi protocol, correspondingly, no matter the designated communication protocol is an intelligent door lock or a gateway, the designated communication protocol and the designated communication protocol are consistent with each other through communication modules configured by the intelligent door lock and the gateway, and the designated communication protocol can be any one or more of a ZigBee communication module, a Bluetooth module and a WiFi communication module.
In order to ensure the security of wireless communication between the intelligent door lock and the gateway, the specified communication protocols are all configured with encryption algorithms, for example, if the specified communication protocol is a ZigBee protocol, the configured encryption algorithm is an initial symmetric encryption algorithm, so that the encryption complexity is effectively reduced on the premise of ensuring the security of wireless communication.
Still further, symmetric encryption algorithms include, but are not limited to: DES algorithm, 3DES algorithm, TDEA algorithm, Blowfish algorithm, RC5 algorithm, IDEA algorithm, ASE algorithm and the like, so that the safety of wireless communication between the intelligent door lock and the gateway is simply and effectively ensured.
Of course, in other application scenarios, an asymmetric encryption algorithm with higher complexity and higher security may also be adopted according to the actual processing capability of the smart door lock, for example, the asymmetric encryption algorithm includes but is not limited to: RSA algorithm, Elgamal algorithm, knapsack algorithm, Rabin algorithm, D-H algorithm, ECC (elliptic curve cryptography) algorithm, etc.
In step 130, the control instruction data is decrypted according to a symmetric encryption algorithm to obtain decrypted data.
The control instruction data is obtained by encrypting the control instruction sent by the client twice by the gateway, namely the first encryption is carried out according to an encryption algorithm configured in a specified communication protocol, and the second encryption is carried out according to a symmetric encryption algorithm.
It should be understood that symmetric encryption algorithm means that the encryption algorithm used for encryption and decryption are identical. Therefore, after receiving the control instruction data sent by the gateway, the intelligent door lock firstly decrypts the control instruction data for the first time by using a symmetric encryption algorithm.
For example, if the symmetric encryption algorithm used by the gateway to encrypt the encrypted data is the ASE algorithm, the symmetric encryption algorithm used by the intelligent door lock to decrypt the control instruction data is correspondingly the ASE algorithm.
In step 150, performing secondary decryption on the decrypted data according to an encryption algorithm configured in a specified communication protocol, to obtain a control instruction, where the specified communication protocol is used to establish a communication connection with the gateway.
After the control instruction data sent by the gateway is decrypted for the first time by executing the symmetric encryption algorithm, the intelligent door lock also decrypts the decrypted data for the second time according to the encryption algorithm configured in the specified communication protocol.
As mentioned above, the intelligent door lock and the gateway are respectively configured with a communication module, so that the intelligent door lock and the gateway are respectively connected with each other through a wireless or wired network according to a specified communication protocol supported by the communication module configured for the intelligent door lock and the gateway, and further, the communication between the intelligent door lock and the gateway is realized through the network connection.
Therefore, for the intelligent door lock, the adopted specified communication protocol is consistent with the specified communication protocol in the gateway, so that secondary decryption of the decrypted data is realized.
For example, if the designated communication protocol adopted by the communication module configured by the gateway is the ZigBee protocol, and the encryption algorithm configured by the designated communication protocol is the initial symmetric encryption algorithm, then, in the communication module configured by the smart door lock, the designated communication protocol is also the ZigBee protocol, and accordingly, the encryption algorithm configured by the designated communication protocol is also the initial symmetric encryption algorithm.
In step 170, the intelligent door lock is controlled to execute corresponding operations according to the control command.
The intelligent door lock respectively adopts a symmetric encryption algorithm and an encryption algorithm configured in a specified communication protocol to decrypt the control instruction data twice, and after the control instruction generated by the client according to the user trigger operation is obtained, the intelligent door lock can execute corresponding operation according to the control instruction.
In an embodiment, if the control instruction instructs the intelligent door lock to perform the operation of adding the unlocking user, the intelligent door lock correspondingly performs the operation of adding the unlocking user, and the fingerprint acquired at the moment is stored in the memory as the user fingerprint, so that the user can conveniently and subsequently use the fingerprint to control the intelligent door lock to perform the unlocking operation.
In this embodiment, the control instruction data sent by the gateway to the intelligent door lock is encrypted twice by the encryption algorithm configured by the specified communication protocol and the symmetric encryption algorithm, so that the security of the transmission of the control instruction data between the intelligent door lock and the gateway is fully ensured, and the security of the wireless communication between the intelligent door lock and the gateway is greatly improved.
In addition, the encryption algorithm and the symmetric encryption algorithm configured by the appointed communication protocol in the intelligent door lock can run in the microprocessor of the intelligent door lock in a client-side mode, namely, the data transmitted between the intelligent door lock and the gateway in the communication process is encrypted by adopting a software encryption scheme, the size of the intelligent door lock cannot be additionally increased, and the production cost of the intelligent door lock is further reduced.
Fig. 4 is a flowchart illustrating the generation of a first key for executing a symmetric encryption algorithm by the smart door lock according to an exemplary embodiment.
As shown in fig. 4, the process of generating the first key by the smart door lock may include the following steps:
in step 131, the first key base sent by the gateway is received, and a second key base is randomly generated according to the first key base.
It should be noted that, in the present embodiment, the smart door lock is configured with a two-dimensional code, which is regarded as a third key base for generating the first key. The third key base is a random number, and the number of bits of the random number is predetermined, for example, the number of bits of the random number is 128 bits.
In an embodiment, the two-dimensional code configured for the smart door lock is used for the smart door lock client to scan, or the user inputs the two-dimensional code into the smart door lock client, so that the smart door lock client identifies the two-dimensional code, thereby obtaining a third key base number represented by the two-dimensional code, and further sending the third key base number to the gateway through interaction between a terminal operated by the smart door lock client and the gateway.
After receiving the third key base number sent by the intelligent door lock client, the gateway can randomly generate the first key base number, store the first key base number in the gateway, and send the first key base number to the intelligent door lock.
For the intelligent door lock, a first key base number sent by the gateway can be received, a second key base number is randomly generated according to the first key base number and is stored in the intelligent door lock, and meanwhile, the second key base number is reported to the gateway.
In step 133, the third key base is read from the memory of the smart door lock.
As described above, the smart door lock is provided with a two-dimensional code, which is regarded as a third key base for generating the first key.
In one embodiment, before the smart door lock leaves the factory, the two-dimensional code is burned into the smart door lock, so that the smart door lock stores the two-dimensional code, for example, the two-dimensional code regarded as the third key base is stored in the memory.
In another embodiment, the two-dimensional code is further attached to the smart door lock in the form of a two-dimensional code label, for example, on the inner side of a battery rear cover of the smart door lock, so that a user can perform two-dimensional code scanning by means of a smart door lock client.
For a smart door lock, the third key base may then be read from memory before the first key is generated.
In step 135, a key operation is performed on the first key base, the second key base, and the third key base to obtain a first key for executing the symmetric encryption algorithm.
After the first key base number, the second key base number and the third key base number are obtained, the intelligent door lock can perform key operation according to the three key base numbers to obtain a first key.
It should be understood that symmetric encryption algorithm means that the encryption algorithm used for encryption and decryption is identical, i.e. the key used for encryption and decryption is symmetric.
Thus, after obtaining the first key base number, the second key base number and the third key base number, the gateway performs a key operation on the obtained three key base numbers by using a symmetric encryption algorithm, so as to obtain a second key symmetric to the first key.
In one embodiment, the key operation is implemented by a message digest algorithm, which may include, for example, a hash operation.
Under the effect of the embodiment, the first key acquired by the intelligent door lock is obtained by performing key calculation on the first key base number, the second key base number and the third key base number, so that the generation of the first key is derived from multi-party data, the complexity of cracking the first key is increased, and the security of wireless communication between the intelligent door lock and the gateway is further enhanced.
FIG. 5 is a flowchart illustrating a key operation of the smart door lock based on the first key base, the second key base, and the third key base in accordance with an exemplary embodiment.
As shown in fig. 5, the process of the smart door lock performing the key operation according to the three key bases may include the following steps:
in step 1351, the first key base, the second key base, and the third key base are operated according to a message digest algorithm to obtain message digest data.
The message digest algorithm preferably adopts irreversible digest operation to ensure that the generated first key is not easy to crack. The message digest algorithm may employ hash operations including, but not limited to, SHA-1 operations or MD5 operations, but SHA-1 operations are preferred in this embodiment.
For convenience of understanding, for example, assuming that the first key base is a, the second key base is B, and the third key base is C, the operation formula for performing the digest operation on the first key base, the second key base, and the third key base by using the SHA-1 operation is SHA-1(a + B + C). Where "a + B + C" denotes that the first, second, and third key bases are numerically concatenated, for example, assuming that a is "1010", B is "1101", C is "1001", and "a + B + C" is "101011011001".
In one embodiment, the third key base is a 128-bit random number, the first key base is a 32-bit random number, and the second key base is a 32-bit random number, the three key bases are concatenated to obtain a 192-bit random number, and the message digest algorithm operates on the 192-bit random number to obtain the message digest data.
For example, if SHA-1 operation is adopted, 160-bit message digest data is generated; if the MD5 operation is used, 128-bit message digest data is generated.
In step 1353, specified data is extracted from the message digest data as the first key.
In order to further ensure that the first secret key is not cracked, the intelligent door lock extracts specified data from the generated message digest data, the extracted specified data is used as the first secret key, and the generated first secret key is stored, so that the intelligent door lock can be called in the subsequent wireless passing process between the intelligent door lock and the gateway.
Taking SHA-1 operation as an example for explanation, assuming that 160-bit message digest data is generated, the low 128-bit number in the 160-bit message digest data may be extracted as the first key, the high 128-bit number in the 160-bit message digest data may also be extracted as the first key, or 128-bit numbers in the 160-bit message digest data may be extracted at random as the first key by negotiating with the gateway, which is not limited herein.
In the embodiment, the smart door lock adopts the message digest algorithm to generate the message digest data, and extracts the specified data from the generated message digest data as the first key, because the message digest algorithm is irreversible, and the extraction of the fixed bit number from the generated message digest data can be randomly specified, the complexity of cracking the first key is fully ensured.
Similarly, in the gateway device, the gateway adopts the same message digest algorithm as the intelligent door lock to calculate the acquired first key base number, the acquired second key base number and the acquired third key base number, and extracts the same designated data from the calculated message digest data to be used as the second key for storage, so as to ensure that the second key is completely consistent with the first key, and further provide a basis for executing the symmetric key algorithm, so as to facilitate the subsequent realization of the security of the wireless communication between the intelligent door lock and the gateway.
Fig. 6 is a flowchart illustrating a method of wireless communication for an intelligent door lock, according to another exemplary embodiment. As shown in fig. 6, the intelligent door lock wireless communication method may further include the steps of:
in step 210, the door lock data stored in the intelligent door lock is encrypted according to the encryption algorithm configured in the specified communication protocol, so as to obtain encrypted data.
The door lock data stored by the intelligent door lock comprise behavior data generated by the intelligent door lock and state data of the intelligent door lock assembly. In one embodiment, the behavior data generated by the intelligent door lock comprises unlocking records and abnormal alarm records.
The unlocking record comprises at least one of unlocking time, unlocking environment and user information, specifically, the unlocking time is the time of unlocking operation executed by the intelligent door lock, the unlocking environment is the face image of the unlocking person shot by the built-in camera of the intelligent door lock when the unlocking operation is executed, and the user information can be the fingerprint of an unlocking person acquired by the fingerprint acquisition module when the unlocking operation is executed by the intelligent door lock or a user account of a client executing control remote unlocking.
The abnormal alarm records comprise at least one of abnormal alarm time and abnormal alarm reasons, wherein the abnormal alarm time is the time for the intelligent door lock to execute the abnormal alarm action, and the abnormal alarm reasons are the trigger reasons for triggering the abnormal alarm action by the intelligent door lock.
In another embodiment, the intelligent door lock assembly comprises at least one of a doorbell, a speaker and a lock tongue, the state data of the intelligent door lock assembly comprises at least one of a doorbell state, a speaker volume, a speaker language and a lock tongue state, specifically, the doorbell state comprises a doorbell closing/opening state, the speaker volume is a volume level state of the speaker playing the prompt voice of the door lock, and the speaker language state comprises a language type of the speaker playing the prompt voice of the door lock, such as a Chinese voice, an English voice, a Korean voice and the like.
The behavior data generated by the intelligent door lock and the state data of the intelligent door lock assembly are stored in the self-configured memory.
The reporting of the door lock data may be performed according to the actual requirements of the user, for example, the reporting may be performed to the gateway in response to a control instruction generated by the client according to the user trigger operation, or may be performed automatically, for example, the unlocking record may be automatically reported to the gateway after the intelligent door lock has performed the unlocking operation.
The encryption algorithm configured in the specified communication protocol is the same as the encryption algorithm configured in the specified communication protocol in step 150, and is not described herein again.
In step 230, the encrypted data is encrypted for the second time according to the symmetric encryption algorithm to obtain data to be sent.
The intelligent door lock encrypts the unlocking record for the first time according to an encryption algorithm configured in the specified communication protocol, and then encrypts the encrypted data for the second time according to a symmetric encryption algorithm stored in the communication module to obtain data to be sent.
As previously described, the smart door lock performs a symmetric encryption algorithm using the first key to encrypt the encrypted data a second time. The obtained data to be sent are data obtained by secondarily encrypting the unlocking records by the intelligent door lock according to an encryption algorithm and a symmetric encryption algorithm configured by a specified communication protocol.
In step 250, the data to be sent is reported to the gateway.
The intelligent door lock reports the data to be sent obtained through secondary encryption to the gateway, so that the gateway decrypts the received data to be sent for the second time and sends the unlocking record obtained through decryption to the client.
Specifically, for the gateway, after receiving data to be transmitted sent by the intelligent door lock, the gateway decrypts the data to be transmitted according to the same symmetric encryption algorithm as the intelligent door lock to obtain corresponding decrypted data, and then decrypts the decrypted data for the second time according to the encryption algorithm configured by the specified communication protocol to obtain the door lock data.
After the gateway decrypts the unlocking records sent by the intelligent door lock, the decrypted door lock data are sent to the client side, so that the client side can display the door lock data in a client side interface for a user to check.

Fig. 7 is a flowchart illustrating a method of wireless communication for an intelligent door lock, according to another exemplary embodiment. As shown in fig. 7, the intelligent door lock wireless communication method may further include the steps of:
in step 310, an intelligent door lock pairing instruction sent by the gateway is received, and pairing operation triggered by a user is detected according to the intelligent door lock pairing instruction.
Before establishing communication connection with the gateway, the intelligent door lock needs to be paired with the gateway, and after the intelligent door lock is successfully paired with the gateway, the intelligent door lock can be in communication connection with the gateway, so that data transmission is performed through communication connection.
The intelligent door lock pairing instruction which is received by the intelligent door lock and paired with the gateway is generated by the client side and is forwarded to the intelligent door lock through the gateway.
Specifically, the client adds a pairing inlet for the user in the client interface, if the user wants to perform pairing between the gateway and the intelligent door lock, related operations are triggered at the pairing inlet, so that the client generates an intelligent door lock pairing instruction according to the related operations, reports the intelligent door lock pairing instruction to the gateway, and sends the intelligent door lock pairing instruction to the intelligent door lock through the gateway.
For the intelligent door lock, after an intelligent door lock pairing instruction sent by a gateway is received, pairing operation triggered by a user in the intelligent door lock is detected in response to the intelligent door lock pairing instruction.
In an embodiment, the intelligent door lock is configured with a pairing key, and when a user presses the pairing key, the intelligent door lock can detect pairing operation triggered by the user. The pressing operation is a pairing operation triggered by a user in the intelligent door lock.
Here, the pairing operation triggered by the user may be a long-time pressing of the pairing key or a short-time pressing of the pairing key, which is related to a preset triggering manner of the smart door lock by the user, and is not limited herein.
In step 330, if the pairing operation triggered by the user is detected, pairing the intelligent door lock and the gateway is performed, so that a communication connection is established between the intelligent door lock and the gateway.
And if the intelligent door lock detects the pairing operation triggered by the user, executing the pairing operation with the gateway so as to facilitate the establishment of communication connection with the gateway.
Further, after the intelligent door lock is successfully paired with the gateway, the pairing result can be sent to the client through the gateway, so that the user can obtain the pairing result of the intelligent door lock and the gateway through the client.
Fig. 8 is a flowchart illustrating a method of wireless communication for an intelligent door lock, according to another exemplary embodiment. As shown in fig. 8, the intelligent door lock wireless communication method may further include the steps of:
in step 410, the verification information stored in the smart door lock is encrypted according to the symmetric encryption algorithm to obtain verification information.
When the intelligent door lock performs decryption/encryption operation on received/transmitted data, the first secret key is used for executing a symmetric encryption algorithm, and when the gateway performs decryption/encryption operation on the received/transmitted data, the second secret key is used for executing the symmetric encryption algorithm.
In order to verify the consistency of the first secret key and the second secret key, the intelligent door lock uses the first secret key as a secret key of a symmetric encryption algorithm to encrypt the stored verification information, and the verification information is obtained. The verification information stored by the intelligent door lock specifically comprises magic numbers agreed by the intelligent door lock and the gateway in advance, and the magic numbers are stored in the intelligent door lock and the gateway.
In step 430, the authentication information is sent to the gateway.
The intelligent door lock sends the encrypted verification information to the gateway, so that the gateway decrypts the verification information according to a corresponding symmetric encryption algorithm.
Specifically, for the gateway, the gateway decrypts the authentication information using the second key when executing the symmetric encryption algorithm, and verifies the decrypted authentication information. The process of verifying the verification information obtained by decrypting by the gateway is specifically a numerical comparison process.
For example, it is described that the verification information carries a magic number negotiated in advance between the smart door lock and the gateway, and if the magic number obtained by the gateway performing the symmetric encryption algorithm decryption is the same as the magic number stored in the gateway, it indicates that the first key and the second key are the same, and the process continues to execute the content described in step 450.
On the contrary, if the magic number obtained by decryption of the gateway is different from the magic number stored in the gateway, the verification is not passed, the first secret key is inconsistent with the second secret key, and in order to prevent data leakage of the intelligent door lock, the communication connection between the intelligent door lock and the gateway can be interrupted, so that the intelligent door lock and the gateway cannot perform data transmission.
In step 450, when the authentication information indicates that the intelligent door lock passes the authentication of the gateway, a communication connection between the intelligent door lock and the gateway is established.
When the verification information obtained by the gateway through executing the symmetric encryption algorithm decryption is completely consistent with the verification information stored in the gateway, the fact that the intelligent door lock passes the verification of the gateway is indicated. Only after the intelligent door lock passes through the gateway verification, the intelligent door lock can establish communication connection with the gateway, and data transmission can be carried out between the intelligent door lock and the gateway.
In this embodiment, the verification information stored in the intelligent door lock is encrypted by the symmetric encryption algorithm and then sent to the gateway, so that the verification is performed after the verification information is decrypted by the gateway, and only after the verification information indicates that the intelligent door lock passes the verification of the gateway, the intelligent door lock can establish communication connection with the gateway, thereby ensuring that the subsequent data transmission process between the intelligent door lock and the gateway can be performed accurately.
