[0002] In an intelligent lock system, in order to prevent local intelligent locks from being breached and for more convenient centralized management, a centralized verification method using an intelligent lock management platform is adopted.

[0020] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase does not necessarily refer to the same embodiment at every occurrence in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] It should be noted that: "a plurality of" mentioned herein refers to two or more.

[0022] The implementation details of the technical solutions of the embodiments of this application are elaborated in detail below: In the first aspect of this embodiment, a cluster verification method for an intelligent lock is implemented. Please refer to Figure 1 , Figure 1 which is a schematic flowchart of a cluster verification method for an intelligent lock disclosed in an embodiment of the present invention. The method includes: S101, read an access permission card according to the first intelligent lock. If the first intelligent lock ID is in the permission list and the first intelligent lock is unreachable from the intelligent lock management platform, broadcast and send a first message to the second intelligent locks in the permission list; the first message includes the IP of the intelligent lock management platform, the permission list, and the second intelligent lock ID; the second intelligent locks are all other intelligent locks in the permission list except the first intelligent lock; the permission list includes user ID, intelligent lock ID, opening time, and verification information; Before reading the access permission card according to the first intelligent lock, the method further includes: Create an access permission card for the user according to the intelligent lock management platform; the access permission card stores a list of permissions; among them, verification information corresponding to different intelligent lock IDs is generated by calculating through the HASH algorithm according to the user ID, intelligent lock ID, and opening time; the verification information includes a verification code.

[0023] Specifically, in this embodiment, when the intelligent lock management platform creates an access permission card for the user and writes the verification information, for user ID-1, based on the list of intelligent lock IDs that can be opened (i.e., the permission list), corresponding to different opening start and end dates of the intelligent lock, the user ID, intelligent lock ID, and start and end date information are used to calculate through the HASH algorithm to generate a verification code.

[0024] For example: For user ID 0x0011, the intelligent locks to be opened include: Intelligent Lock-1: ID0x0021, with an opening time from January 1, 2025 to January 30, 2025, and the verification code calculated through the HASH algorithm is 0xAEDF; Intelligent Lock-2: ID0x0022, with an opening time from January 1, 2025 to February 30, 2025, and the verification code calculated through the HASH algorithm is 0xA13A; Intelligent Lock-3: ID0x0023, with an opening time from January 15, 2025 to February 30, 2025, and the verification code calculated through the HASH algorithm is 0xB1E3.

[0025] Furthermore, when creating an access permission card for the user according to the intelligent lock management platform, it also includes: Generate different encryption keys according to different intelligent lock IDs and send them to the corresponding intelligent locks; Encrypt the verification information in the permission list respectively according to the encryption key and form encrypted verification codes respectively; Accumulate the encrypted verification codes to form a combined verification code and write it into the access permission card.

[0026] Specifically, in this embodiment, to prevent the intelligent lock side from reading the verification code and reverse engineering the HASH algorithm, the intelligent lock management platform also needs to encrypt the verification code. The intelligent lock management platform will generate different encryption keys according to different intelligent lock IDs and synchronize them to the corresponding intelligent locks respectively. For example, the intelligent lock management platform generates an encryption key: abcd for Intelligent Lock-1: ID0x0021, and an encryption key: hijk for Intelligent Lock-2: ID0x0022, etc. Each intelligent lock can only know its own encryption key.

[0027] It should be noted that Intelligent Lock-1 can correspond to the first intelligent lock in this example; Intelligent Lock-2 and Intelligent Lock-3 (mentioned below) correspond to the second intelligent lock in this example.

[0028] The intelligent lock management platform will encrypt the corresponding verification codes with the encryption keys of the intelligent locks corresponding to the intelligent lock ID list in the intelligent lock ID list respectively. For example, it encrypts the verification code 0xAEDF with the encryption key: abcd, and encrypts the verification code 0xA13A with the encryption key: hijk. The intelligent lock management platform accumulates all the encrypted verification codes to generate the final verification code, for example: 0x1ehf. Finally, the user ID - 1, the list of intelligent lock IDs that can be opened, the different opening start and end dates corresponding to the intelligent locks, and the finally synthesized verification code are written into the user access privilege card.

[0029] Next, this example will start to illustrate how the intelligent lock reads the information of the access privilege card and, when it recognizes that the intelligent lock management platform is unreachable, uses the local cluster mode to calculate the verification code respectively for joint verification.

[0030] Specifically, in this embodiment, when the user uses the user access privilege card to open the intelligent lock, for example, intelligent lock - 1, intelligent lock - 1 reads the information of the user access privilege card, first obtains the user ID, and reads the intelligent lock ID list. If the ID of the intelligent lock itself is not in the list, it returns verification failure. If it is in the list, it further compares the opening time. If the unlocking time is within the opening start and end date period corresponding to the lock ID, it enters the verification code verification stage. If it is not within the time period, it returns verification failure.

[0031] S102, check the connection status between the second intelligent lock and the intelligent lock management platform according to the first message, and return the second message to the second intelligent lock; the connection status includes reachable and unreachable; the second message includes the connection status, the second intelligent lock ID, and the second intelligent lock IP; Specifically, in this embodiment, when intelligent lock - 1 enters the verification code verification stage, if the intelligent lock management platform is reachable, it sends the user ID and the corresponding verification code to the intelligent lock management platform; if it is found that the intelligent lock management platform is unreachable, it uses the local cluster mode for verification; Intelligent lock - 1 sends a broadcast query message to other intelligent locks to query that the intelligent lock management platform is unreachable. If the intelligent locks are deployed using a layer - 2 network, the broadcast query can be sent in the layer - 2 broadcast mode. If a layer - 3 network is used, multicast can be used. The intelligent lock sends an IGMP join message to join the same multicast group, establish a multicast forwarding tree, and send the broadcast query message in the form of a multicast message to the multicast forwarding tree and then to other intelligent locks in the form of a multicast packet. The broadcast query message (i.e., the first message) sent by the intelligent lock includes the intelligent lock management platform IP and the information of the intelligent lock ID that needs to be jointly verified (consistent with the intelligent lock list) to confirm whether there are other intelligent locks in the intelligent lock list in a connected state with the intelligent lock management platform.

[0032] Other intelligent locks, that is, the second intelligent lock in this example, such as Intelligent Lock - 2 and Intelligent Lock - 3, after receiving the query message sent by Intelligent Lock - 1, first determine whether the IP of the intelligent lock management platform sent is the same as its own intelligent lock management platform IP, and whether its own ID exists in the intelligent lock ID list. If they are not the same, no processing is performed. If they are the same, then check the connection status between itself and the intelligent lock management platform. If it is reachable, a unicast method is used to return an intelligent lock management platform reachable message to Intelligent Lock - 1, carrying the local intelligent lock ID and IP; if it is unreachable, a unicast method is used to return an intelligent lock management platform unreachable message to Intelligent Lock - 1, carrying the local intelligent lock ID and IP.

[0033] If Intelligent Lock - 1 receives an intelligent lock management platform reachable message returned by other intelligent locks, it considers it a fault of its own intelligent lock, exits the local cluster mode, and waits for Intelligent Lock - 1 to restore the connection with the intelligent lock management platform.

[0034] S103, in response to the connection statuses in the second message all being unreachable, the first intelligent lock sends a collaborative calculation verification code request to the second intelligent lock based on the second intelligent lock IP; the first intelligent lock determines the first verification code according to the first intelligent lock ID and its opening time in the permission list, and the second intelligent lock determines the second verification code according to the collaborative calculation verification code request and the second intelligent lock ID and its opening time in the permission list, and returns it to the first intelligent lock; Furthermore, the collaborative calculation verification code request includes the user ID and the opening time of the first intelligent lock ID; the second intelligent lock determines the second verification code according to the collaborative calculation verification code request and the second intelligent lock ID and its opening time in the permission list, and returns it to the first intelligent lock, including: after receiving the collaborative calculation verification code request, the second intelligent lock calculates the second verification code through the HASH algorithm according to the user ID, the second intelligent lock ID, and its opening time; encrypts the second verification code based on the encryption key corresponding to the second intelligent lock ID to obtain the second encrypted verification code, and sends it to the first intelligent lock.

[0035] Furthermore, the first intelligent lock determines the first verification code according to the first intelligent lock ID and its opening time in the permission list, including: the first intelligent lock calculates the first verification code through the HASH algorithm according to the user ID, the first intelligent lock ID, and its opening time; encrypts the first verification code based on the encryption key corresponding to the first intelligent lock ID to obtain the first encrypted verification code.

[0036] Specifically, in this embodiment, if confirmation messages indicating that the intelligent lock management platform is unreachable are received from all other intelligent locks in the intelligent lock list, the intelligent lock IDs and corresponding IP addresses are recorded, and requests for collaborative calculation verification codes are sent to the intelligent locks in the list, each carrying the user ID and the opening time corresponding to the intelligent lock ID. For example, Intelligent Lock - 1 sends the user ID: 0x0011 and the opening time from January 1, 2025 to February 30, 2025 to Intelligent Lock - 2, and sends the ID: 0x0011 and the opening time from January 15, 2025 to February 30, 2025 to Intelligent Lock - 3.

[0037] After receiving the request message for collaborative calculation verification code sent by Intelligent Lock - 1, Intelligent Lock - 2 and Intelligent Lock - 3 calculate the verification code through the HASH algorithm using the user ID, their own intelligent lock ID and the corresponding opening time, and then further encrypt the verification code with the encryption key synchronized by the previous intelligent lock management platform to their own intelligent locks to form a second encrypted verification code, and return it to Intelligent Lock - 1.

[0038] Intelligent Lock - 1 also calculates the verification code through the HASH algorithm using the opening time, user ID and intelligent lock ID for its own lock ID, and then encrypts it with the encryption key synchronized by the intelligent lock management platform to its own intelligent lock to form a first encrypted verification code.

[0039] S104, the first intelligent lock opens the first intelligent lock according to the comparison between the first verification code, the second verification code and the verification information.

[0040] Further, the first intelligent lock opens the first intelligent lock according to the comparison between the first verification code, the second verification code and the verification information, including: the first intelligent lock accumulates the first encrypted verification code and the second encrypted verification code to generate a third verification code; according to the comparison between the third verification code and the synthesized verification code, if they are consistent, the verification passes and the first intelligent lock is opened.

[0041] Specifically, in this embodiment, Intelligent Lock - 1 also calculates the verification code through the HASH algorithm using the opening time, user ID and intelligent lock ID for its own lock ID, then encrypts it with the encryption key synchronized by the intelligent lock management platform to its own intelligent lock, and accumulates it with the encrypted verification codes returned by Intelligent Lock - 2 and Intelligent Lock - 3 to obtain the encrypted verification code for verification. Intelligent Lock - 1 compares the encrypted verification code for verification with the verification code read from the user access permission card. If they are consistent, the verification passes and the intelligent lock is opened. If they are inconsistent, the verification fails and "unauthorized access" is returned.

[0042] Based on this, in this embodiment, the intelligent lock management platform generates verification codes for users respectively based on different lock IDs that can be accessed and the corresponding access times, encrypts them with different encryption keys respectively, and then aggregates them into the final encrypted verification code; the intelligent lock synchronizes the reachable status of the intelligent lock management platform through broadcasting or multicasting, and for the status judged as unreachable, it adopts the local cluster mode for verification; the intelligent lock initiates a collaborative verification operation to other intelligent locks in the intelligent lock list in the local cluster mode. Different intelligent locks respectively calculate the verification codes corresponding to their own locks and encrypt them with their own encryption keys, and finally the verified intelligent lock conducts an aggregated judgment. Thus, when the intelligent lock management platform is unreachable, the intelligent lock realizes joint verification through the local cluster, ensuring the availability of the intelligent lock verification service, while guaranteeing the verification security and avoiding the single-point risk that a single intelligent lock is easily broken.

[0043] In addition, the second aspect of this embodiment provides a cluster verification system for intelligent locks, as Figure 2 shown. The system includes a reading module 201, an inspection module 202, a collaborative request module 203, and a verification module 204; where: The reading module 201 is used to read an access permission card according to the first intelligent lock. If the first intelligent lock ID is in the permission list and the first intelligent lock is unreachable from the intelligent lock management platform, it broadcasts and sends a first message to the second intelligent locks in the permission list; the first message includes the intelligent lock management platform IP, the permission list, and the second intelligent lock ID; the second intelligent locks are all other intelligent locks in the permission list except the first intelligent lock; the permission list includes the user ID, the intelligent lock ID, the opening time, and the verification information. The inspection module 202 is used to check the connection status between the second intelligent lock and the intelligent lock management platform according to the first message and return a second message to the second intelligent lock; the connection status includes reachable and unreachable; the second message includes the connection status, the second intelligent lock ID, and the second intelligent lock IP. The collaborative request module 203 is used to, in response to the connection status in the second message all being unreachable, the first intelligent lock sends a collaborative calculation verification code request to the second intelligent lock based on the second intelligent lock IP; the first intelligent lock determines a first verification code according to the first intelligent lock ID and its opening time in the permission list, and the second intelligent lock determines a second verification code according to the collaborative calculation verification code request and the second intelligent lock ID and its opening time in the permission list, and returns it to the first intelligent lock. The verification module 204 enables the first intelligent lock to compare the first verification code, the second verification code with the verification information, and open the first intelligent lock.

[0044] Furthermore, the system further includes a creation module 200, which is used for: Create an access permission card for the user according to the intelligent lock management platform; the access permission card stores a permission list; wherein, according to the user ID, intelligent lock ID, and opening time, verification information corresponding to different intelligent lock IDs is calculated through the HASH algorithm; the verification information includes a verification code.
