[0040] In order to make the objects, technical solutions and advantages of the present application clearer and more explicit, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.

[0041] The prior art has many deficiencies in encrypted communication for intelligent door locks. Because the prior art intelligent lock collects data (such as door opening and closing records, fingerprints, and facial information), with the increase in data leakage events, the encrypted communication of the prior art cannot use a single key for encryption and decryption in the encryption process, and there is a risk of cracking. Therefore, an intelligent door lock encrypted communication method is needed, which not only uses a single key for encryption and decryption in the encryption process when the device connects to the server, but also prevents hacking and data leakage.

[0042] The intelligent door lock encrypted communication method of the preferred embodiment of the present application, as shown in Figure 1 and Figure 2 The intelligent door lock encrypted communication method comprises the following steps:

[0043] Step S10, obtain the device number, if the device number belongs to the preset device number stored in the server, obtain the first communication key according to the preset device number, and generate a network configuration password according to the first communication key.

[0044] Specifically, the device number (SN) is obtained, and the device number is matched with the preset device number stored in the server (the device management platform matches the device number input on the page with the existing device number in the database, and after successful matching, a five-minute valid period network configuration password is generated using the first communication key corresponding to the device number; if the matching fails, the session is logged out, and the process is ended); if the matching is successful, the first communication key associated with the matching successful preset device number is obtained (the first communication key is a permanent key written in the production test stage, which serves as a basic key when the device does not negotiate the second communication key and the third communication key with the server, and the first communication key is saved in the server database and managed by the platform), and a network configuration password is generated according to the first communication key.

[0045] Further, the first data content (data packet) is decrypted according to the first communication key to obtain a network configuration timestamp (the device management platform uses the first communication key to decrypt the received first data content when receiving a connection request, and the decrypted data should be the network configuration timestamp), and it is judged whether the network configuration timestamp is within the preset time; if the network configuration timestamp is within the preset time, the first data content is marked as decrypted successfully (after successful matching, it is judged whether the timestamp is within five minutes, and if so, the first data content is considered to be decrypted successfully).

[0046] Step S20, if the matching of the network configuration password and the stored preset password is successful, the received first data content is decrypted to obtain a communication address, a second communication key is generated according to the first communication key based on the communication address, and is sent to the server.

[0047] Specifically, the network configuration password is matched with the stored preset password (whether the network configuration password can be matched is judged, if the matching fails, an error is returned, the network configuration session is logged out, and if the matching succeeds, it is judged whether the time stamp is within five minutes, if yes, it is considered that the decryption is successful), if the matching succeeds, the first data content distributed by the server is received, the first data content is decrypted according to the first communication key (PWD1) to obtain a communication address (device address and server address); a second communication key (PWD2) is generated according to the first communication key, the second communication key is sent to the server according to the communication address (at this time, the message sent by the device to the server is that the source address is the device address, the target address is the server address; the reply content is the second communication key, the first communication key is used as a random number seed to randomly generate the second communication key, the life cycle of the second communication key is self-defined, and the communication address is encrypted by the first communication key).

[0048] Step S30, receiving the third communication key sent by the server, the third communication key being generated by the server according to the second communication key.

[0049] Specifically, the third communication key (PWD3) sent by the server is received, the third communication key being generated by the server according to the second communication key (after receiving the data, the server uses the first communication key to decrypt the second communication key and the life cycle of the second communication key, returns the third communication key to the device according to the self-defined message format that the source address and the target address are set to default values before the address is distributed, the default value can be all 0xFF data, uses the second communication key and the time stamp SHA1 and the life cycle of the third communication key, the length of the life cycle is self-defined, and the communication address is encrypted by the second communication key).

[0050] Further, the life cycle of the second communication key and the life cycle of the third communication key are acquired; when the server and the device perform encrypted communication, it is judged whether the life cycle of the second communication key and the life cycle of the third communication key conform to a preset period; if the life cycle of the second communication key and the life cycle of the third communication key conform to the preset period, an update instruction is acquired, and the life cycle of the second communication key and the life cycle of the third communication key are updated according to the update instruction (after encrypted communication is established, it is needed to judge whether the life cycle of the second communication key and the life cycle of the third communication key will expire, and the second communication key and the third communication key are updated in time before the key expires).

[0051] In step S40, the temporary password generated by the server is received, and if the target password generated by the smart door lock is the same as the temporary password, the information communicated with the server is encrypted according to the third communication key.

[0052] Specifically, a target password is generated according to the third communication key, and the target password is sent to the server, the device uses the second communication key to decrypt the third communication key and the life cycle of the third communication key; the third communication key is used as the key key to generate a target password using the TOTP algorithm and return to the server, the communication address is encrypted using the second communication key, the comparison result of comparing the temporary password generated by the server and the target password is received, the server also uses the third communication key as the key key to generate a temporary password using the TOTP algorithm and compares it with the received target password to obtain a comparison result, and if the comparison is successful, a success is returned; if the comparison result is that the temporary password and the target password are the same, the information communicated with the server is encrypted through the third communication key.

[0053] The beneficial effects of the present application are as follows:

[0054] (1) According to the encryption scheme, the temporary password generated has a fixed life cycle and is automatically invalidated after a period of time.

[0055] (2) The present application does not need a special encryption chip, and will not increase the cost of the device.

[0056] (3) In the present application, the second communication key and the third communication key have a life cycle and can be updated at any time, rather than being valid before unbinding, and users will almost not unbind and update the key in the normal use process.

[0057] (4) In the present application, the communication password and the key encryption key are separated, even if the communication key is cracked, the key is not transmitted in plaintext, and the second communication key and the third communication key will be updated within a certain period of time.

[0058] (5), the session timeout and re-authentication mechanism of the application ensures that the security of the system will not be reduced even in the process of network deployment.

[0059] (6) Even if the attacker intercepts the network deployment request, it cannot use the request after the network deployment token expires, thereby effectively preventing replay attacks.

[0060] (7), the application uses device encrypted data packets for identity authentication, ensuring that only legitimate devices communicate with the server.

[0061] Further, as Figure 3 shown, based on the above-mentioned smart door lock encryption communication method, the application also correspondingly provides a smart door lock encryption communication system, wherein the smart door lock encryption communication system comprises:
