[0036] Mesh networks are widely used in home and enterprise environments due to their high coverage and stable connection advantages. In a Mesh network, all Mesh nodes are connected to each other, each Mesh node has multiple connection channels, and all Mesh nodes form an integrated network. Therefore, when any Mesh node in the Mesh network is compromised, the security of the entire network will be threatened. Attackers can use this vulnerability to threaten the entire network for a long time, resulting in low security of the Mesh network.
[0037] In order to solve the above technical problems, the present application proposes a Mesh password update method, which is applied to a target Mesh node. The target Mesh node is any Mesh node in the Mesh network. The Mesh node is provided with a Bluetooth Low Energy (BLE) module. The target Mesh node receives the password update broadcast sent by the BLE control module based on the target broadcast frequency through the BLE module. The password update broadcast carries the target Mesh password; the target Mesh password is set through the device side and sent to the BLE control module; the password is updated based on the target Mesh password; the target Mesh password is synchronized to other Mesh nodes in the Mesh network, thereby improving the security of the Mesh network.
[0038] For ease of understanding, the technical solution of the present application will be described in detail below with reference to the accompanying drawings.
[0039] Figure 1 A Mesh password update system is provided in one embodiment of the present application. Figure 1As shown, the Mesh password update system 100 includes a Mesh network 110, a BLE control module 120 and a device end 130. The Mesh network 110 is connected to the BLE control module 120 in communication, and the BLE control module 120 is connected to the device end 130 in communication; the Mesh network 110 includes a plurality of Mesh nodes 111; and the Mesh node 111 is provided with a BLE module. Among them, any Mesh node 111 in the Mesh network 110 adds a low-cost BLE module based on the Mesh network technology, and is expanded on the basis of the Mesh protocol to realize password update based on the target Mesh password, and synchronize the target Mesh password to other Mesh nodes 111 in the Mesh network 110.
[0040] Specifically, the device end 130 is used to obtain the target broadcast frequency and the target Mesh password; generate password update configuration information using the target broadcast frequency and the target Mesh password, and send the password update configuration information to the BLE control module 120.
[0041] Exemplarily, the device end 130 may be a mobile phone, a tablet, a laptop computer, a wearable device, etc. In some embodiments, the device end 130 may have a good user interaction interface, for example, a touch screen, a camera, etc.
[0042] Specifically, the BLE control module 120 is used to receive the password update configuration information sent by the device end 130, and send a password update broadcast to the Mesh network 110 based on the target broadcast frequency; the password update broadcast carries the target Mesh password.
[0043] Specifically, any Mesh node 111 in the Mesh network 110 is used to receive through the BLE module the password update broadcast carrying the target Mesh password sent by the BLE control module 120 based on the target broadcast frequency, update the password based on the target Mesh password, and synchronize the target Mesh password to other Mesh nodes 111 in the Mesh network 110; after obtaining the target Mesh password, other Mesh nodes 111 also update the password based on the target Mesh password, and synchronize the target Mesh password to other Mesh nodes 111 in the Mesh network 110; so that each Mesh node in the Mesh network 110 is updated to the target Mesh password.
[0044] In one possible implementation, after the device end 130 is authorized by management, it obtains the target broadcast frequency and the target Mesh password through the user interaction interface; sends the password update configuration information including the target broadcast frequency and the target Mesh password to the BLE control module 120, and the BLE control module 120 sends a password update broadcast to the Mesh network 110 based on the target broadcast frequency, and the password update broadcast carries the target Mesh password; any Mesh node 111 in the Mesh network 110 receives the password update broadcast through the BLE module, updates the password based on the target Mesh password, and synchronizes the target Mesh password to other Mesh nodes 111 in the Mesh network 110.
[0045] In another possible implementation, when the device 130 is authorized by the application, the current Mesh password of the Mesh network 110 is obtained through the BLE control module 120, and a communication connection is established with any Mesh node 111 in the Mesh network 110 through the current Mesh password of the Mesh network 110.
[0046] Understandably, Figure 1 The system architecture shown is only an example of the Mesh password update system provided by the present application. In other embodiments of the present application, the Mesh password update system 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware, and the present application does not limit this.
[0047] The present embodiment provides a Mesh password updating system, in which any Mesh node in the Mesh network can use the target Mesh password received based on the target broadcast frequency to update the Mesh passwords of all Mesh nodes in the Mesh network, so that the Mesh passwords of all Mesh nodes in the Mesh network can be continuously updated at the target broadcast frequency. Therefore, even if the current Mesh password of a Mesh node is hacked, security will be restored the next time the password is updated according to the target broadcast frequency. The security of the entire Mesh network will not be threatened for a long time due to the hacking of a Mesh node, thereby improving the security of the Mesh network.
[0048] Figure 2 A flow chart of a Mesh password update method provided in an embodiment of the present application is shown. For the sake of convenience, only the part related to the present embodiment is shown. The method provided in the present embodiment is applied to a target Mesh node. The target Mesh node is any Mesh node in the Mesh network. The Mesh node is provided with a BLE module. As an example, the Mesh network and the target Mesh node can be respectively Figure 1The Mesh network 110 and the Mesh node 111 in the Mesh password update system 100 shown in the figure, the method provided in this embodiment includes the following steps:
[0049] S210, receiving, through the BLE module, a password update broadcast sent by the BLE control module based on the target broadcast frequency, where the password update broadcast carries a target Mesh password; the target Mesh password is set by the device side and sent to the BLE control module.
[0050] Specifically, any Mesh node in the Mesh network is equipped with a BLE module. The BLE module is a wireless communication module widely used in IoT devices, supporting Bluetooth protocol 4.0 or higher, with the characteristics of low power consumption, low cost and long-distance communication; it supports multiple working modes, including master mode, slave mode, master-slave mode, broadcast mode, etc. In this embodiment, a low-cost BLE module is added on the basis of Mesh network technology, and it is expanded on the basis of Mesh protocol.
[0051] In the specific implementation, the BLE module starts broadcast scanning and reception in real time. The target Mesh node in the Mesh network receives the password update broadcast sent by the BLE control module based on the target broadcast frequency through the BLE module. The password update broadcast carries the target Mesh password set by the device side and sent to the BLE control module.
[0052] As an example, before the target Mesh node receives the password update broadcast sent by the BLE control module based on the target broadcast frequency through the BLE module, the password management enable broadcast sent by the BLE control module is received through the BLE module. The password management enable broadcast carries a password management enable instruction set by the device side and sent to the BLE control module. The password management enable instruction is used to instruct the target Mesh node to enable the password management function. After the target Mesh node turns on the password management function based on the password management enable instruction, the password update broadcast sent by the BLE control module based on the target broadcast frequency can be identified through the BLE module.
[0053] As an example, the target Mesh node can also receive the password management shutdown broadcast sent by the BLE control module through the BLE module. The password management shutdown broadcast carries the password management shutdown instruction set by the device side and sent to the BLE control module. The password management shutdown instruction is used to instruct the target Mesh node to turn off the password management function.
[0054] S220: Update the password based on the target Mesh password.
[0055] In a specific implementation, the target Mesh node parses the received password update broadcast, obtains the target Mesh password, and uses the target Mesh password to update the current Mesh password. The current Mesh password of the target Mesh node is the Mesh password currently being used by the target Mesh node.
[0056] As an example, when the target Mesh node parses the received password update broadcast and obtains the target Mesh password, it directly changes the current Mesh password to the target Mesh password.
[0057] As another example, when the target Mesh node parses the received password update broadcast and obtains the target Mesh password, it first compares the current Mesh password with the target Mesh password. When the current Mesh password is different from the target Mesh password, the current Mesh password is replaced with the target Mesh password.
[0058] Optionally, after the current Mesh password is changed to the target Mesh password, the current Mesh password is stored.
[0059] S230, synchronizing the target Mesh password to other Mesh nodes in the Mesh network.
[0060] In a specific implementation, the target Mesh node synchronizes the parsed target Mesh password to all Mesh nodes in the Mesh network, so that the Mesh passwords of all Mesh nodes in the Mesh network are updated to the target Mesh password.
[0061] The technical solution provided by this embodiment is that any Mesh node in the Mesh network can use the target Mesh password received based on the target broadcast frequency to update the Mesh password of all Mesh nodes in the Mesh network, so that the Mesh passwords of all Mesh nodes in the Mesh network can be continuously updated at the target broadcast frequency. Therefore, even if the current Mesh password of a Mesh node is cracked, it will be restored to security when the password is updated next time according to the target broadcast frequency, and the security of the entire Mesh network will not be threatened for a long time because of the cracking of a Mesh node. Therefore, the technical solution provided by this embodiment can improve the security of the Mesh network.
[0062] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, the password is updated based on the target Mesh password, including:
[0063] Compare the target Mesh password with the current Mesh password;
[0064] When the target Mesh password is different from the current Mesh password, the current Mesh password is updated with the target Mesh password.
[0065] In the specific implementation, after the target Mesh node obtains the target Mesh password by parsing the password update broadcast, it compares the target Mesh password with the current Mesh password. When the target Mesh password is different from the current Mesh password, the current Mesh password is replaced with the target Mesh password; when the target Mesh password is the same as the current Mesh password, there is no need to update the password.
[0066] The technical solution provided in this embodiment is that when the target Mesh password is different from the current Mesh password of the target Mesh node, the current Mesh password is updated using the target Mesh password; when the target Mesh password is the same as the current Mesh password of the target Mesh node, the password is not updated, which improves the efficiency of password update and saves network resources.
[0067] Figure 3 A flow chart of another Mesh password update method provided in an embodiment of the present application is shown. For the sake of convenience, only the part related to the present embodiment is shown. The method provided in the present embodiment is applied to a BLE control module, and the BLE control module is connected to the Mesh network for communication. As an example, the BLE control module and the Mesh network can be respectively Figure 1 The BLE control module 120 and the Mesh network 110 in the Mesh password update system 100 shown in the figure, the method provided in this embodiment includes the following steps:
[0068] S310, receiving password update configuration information sent by the device, where the password update configuration information includes a target Mesh password and a target broadcast frequency.
[0069] In the specific implementation, the BLE control module first establishes an authentication connection with the device. After the authentication connection is established, the BLE control module determines whether the device has management authority. After determining that the device has management authority, the BLE control module receives the password update configuration information sent by the device. The password update configuration information includes the target Mesh password and the target broadcast frequency. Among them, the authentication connection adopts an encrypted authentication method.
[0070] As an example, after completing the authentication connection with the device and determining that the device has management authority, the BLE control module also receives a password management enable instruction or a password management disable instruction sent by the device. The password management enable instruction is used to instruct the target Mesh node to enable the password management function, and the password management disable instruction is used to instruct the target Mesh node to disable the password management function.
[0071] As another example, after the BLE control module completes the authentication connection with the device end, it is determined that the device end has application permissions. The BLE control module can receive a Mesh password request message sent by the device end with application permissions, and based on the Mesh password request message, send the current Mesh password of the Mesh network to the device end with application permissions, so that the device end with application permissions can establish a communication connection with any Mesh node in the Mesh network through the current Mesh password.
[0072] S320, sending a password update broadcast to the Mesh network based on the target broadcast frequency, the password update broadcast carries the target Mesh password, so that the target Mesh node in the Mesh network receives the password update broadcast through the BLE module, updates the password based on the target Mesh password, and synchronizes the target Mesh password to other Mesh nodes in the Mesh network.
[0073] In a specific implementation, the BLE control module sends a password update broadcast carrying a target Mesh password to the Mesh network according to the target broadcast frequency set therein based on the received password update configuration information.
[0074] As an example, the BLE control module first sends a password management enable broadcast to the Mesh network. The password management enable broadcast carries a password management enable instruction set by the device and sent to the BLE control module, so that the target Mesh node in the Mesh network enables the password management function based on the password management enable instruction, and then sends a password update broadcast carrying the target Mesh password to the Mesh network based on the target broadcast frequency.
[0075] As another example, the BLE control module sends a password management shutdown broadcast to the Mesh network, and the password management shutdown broadcast carries a password management shutdown instruction set by the device side and sent to the BLE control module, so that the target Mesh node in the Mesh network shuts down the password management function based on the password management shutdown instruction.
[0076] In one possible implementation, the password update configuration information sent by the device received by the BLE control module includes a target Mesh password and a target broadcast frequency. The BLE control module sends a password update broadcast to the Mesh network based on the target broadcast frequency, and the password update broadcast carries the target Mesh password.
[0077] In another possible implementation, the BLE control module receives the password update configuration information sent by the device according to the target broadcast frequency. The password update configuration information only includes a target Mesh password. After receiving the password update configuration information, the BLE control module immediately sends a password update broadcast to the Mesh network. The password update broadcast carries the target Mesh password, so that the Mesh network can update the password according to the target broadcast frequency.
[0078] In the technical solution provided by this embodiment, the BLE control module and the device end use an encrypted authentication method to authenticate the connection, thereby improving the security of the network connection; in addition, the BLE control module sends a password update broadcast to the Mesh network based on the target broadcast frequency, which enables the Mesh network to continuously update the Mesh password according to the target broadcast frequency, thereby improving the security of the Mesh network.
[0079] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, the password update configuration information includes multiple target Mesh passwords and a target broadcast frequency; sending a password update broadcast to the Mesh network based on the target broadcast frequency includes:
[0080] Generate corresponding password update broadcasts according to each target Mesh password;
[0081] Send each password update broadcast to the Mesh network in sequence according to the target broadcast frequency.
[0082] In a specific implementation, the password update configuration information sent by the device side received by the BLE control module includes multiple target Mesh passwords and a target broadcast frequency, indicating that multiple target Mesh passwords are sent to the Mesh network in sequence according to the same target broadcast frequency. The BLE control module generates corresponding password update broadcasts according to each target Mesh password, and then sends each password update broadcast to the Mesh network in sequence according to the target broadcast frequency, so that the Mesh password of the Mesh network is updated in sequence to the target Mesh password corresponding to each password update broadcast according to the target broadcast frequency.
[0083] As an example, the password update configuration information includes three target Mesh passwords and a target broadcast frequency, where the three target Mesh passwords are 123, 456, and 789 respectively, and the target broadcast frequency is 6 times / hour, that is, once every 10 minutes. The BLE control module sends a password update broadcast to the Mesh network 10 minutes after receiving the password update configuration information, carrying the target Mesh password 123; after another 10 minutes, it sends a password update broadcast to the Mesh network, carrying the target Mesh password 456; after another 10 minutes, it sends a password update broadcast to the Mesh network, carrying the target Mesh password 789.
[0084] The technical solution provided in this embodiment is that the device side can set multiple target Mesh passwords at the same time by sending a password update configuration information to the BLE control module, so that the BLE control module generates corresponding multiple password update broadcasts according to the multiple target Mesh passwords, and sends them to the Mesh network in sequence according to the target broadcast frequency, thereby improving the efficiency of password update and saving network resources.
[0085] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, the password update configuration information includes multiple target Mesh passwords and target broadcast frequencies corresponding to each target Mesh password; sending a password update broadcast to the Mesh network based on the target broadcast frequency includes:
[0086] Generate corresponding password update broadcasts according to each target Mesh password;
[0087] Each password update broadcast is sent to the Mesh network in sequence according to the target broadcast frequency corresponding to each target Mesh password.
[0088] In a specific implementation, the password update configuration information sent by the device side received by the BLE control module includes multiple target Mesh passwords and target broadcast frequencies corresponding to each target Mesh password, indicating that the target Mesh passwords are broadcast to the Mesh network in sequence according to the target broadcast frequencies corresponding to each target Mesh password. The BLE control module generates corresponding password update broadcasts according to each target Mesh password, and then sends each password update broadcast to the Mesh network in sequence according to the target broadcast frequencies corresponding to each target Mesh password, so that the Mesh password of the Mesh network is updated to the target Mesh password corresponding to each password update broadcast in sequence according to different target broadcast frequencies.
[0089] As an example, the password update configuration information includes 3 target Mesh passwords and 3 target broadcast frequencies corresponding to the 3 target Mesh passwords, wherein the 3 target Mesh passwords are 123, 456, and 789 respectively. The target broadcast frequency corresponding to the target Mesh password 123 is 6 times / hour, that is, it is sent once every 10 minutes; the target broadcast frequency corresponding to the target Mesh password 456 is 3 times / hour, that is, it is sent once every 20 minutes; the target broadcast frequency corresponding to the target Mesh password 789 is 2 times / hour, that is, it is sent once every 30 minutes; then the BLE control module sends a password update broadcast to the Mesh network 10 minutes after receiving the password update configuration information, carrying the target Mesh password 123; after another 20 minutes, it sends a password update broadcast to the Mesh network, carrying the target Mesh password 456; after another 30 minutes, it sends a password update broadcast to the Mesh network, carrying the target Mesh password 789.
[0090] The technical solution provided in this embodiment is that the device side can simultaneously set multiple target Mesh passwords and target broadcast frequencies corresponding to each target Mesh password by sending a password update configuration information to the BLE control module, so that the BLE control module can send password update broadcasts to the Mesh network according to different target broadcast frequencies, and the Mesh network can update the password according to different target broadcast frequencies, thereby improving the efficiency and flexibility of the password update and saving network resources.
[0091] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, before sending a password update broadcast to the Mesh network based on the target broadcast frequency, it also includes:
[0092] The password update broadcast is processed using an encryption algorithm and / or a signature algorithm.
[0093] In a specific implementation, before sending a password update broadcast to the Mesh network based on the target broadcast frequency, the BLE control module uses an encryption algorithm to process the password update broadcast, or uses a signature algorithm to process the password update broadcast, or uses an encryption algorithm and a signature algorithm to process the password update broadcast at the same time, wherein the encryption algorithm uses a symmetric encryption algorithm or an asymmetric encryption algorithm.
[0094] As an example, when a symmetric encryption algorithm is used, the BLE control module uses its own key to encrypt the password update broadcast and sends the encrypted password update broadcast to the Mesh network. The target Mesh node uses the same key to decrypt the password update broadcast to obtain the target Mesh password.
[0095] As another example, when an asymmetric encryption algorithm is used, the BLE control module uses a public key to encrypt the password update broadcast and sends the encrypted password update broadcast to the Mesh network. The target Mesh node uses a private key to decrypt the password update broadcast to obtain the target Mesh password.
[0096] As another example, when a signature algorithm is used, the BLE control module uses a hash function to generate a summary value for the password update broadcast, and then uses its own private key to encrypt the summary value to form a digital signature, and sends the password update broadcast and the digital signature to the target Mesh node. The target Mesh node uses the public key of the BLE control module to decrypt the digital signature to obtain the original summary value, and at the same time uses the same hash function to generate a new summary value for the received password update broadcast. If the two summary values are the same, the signature verification is successful, and the password update broadcast is considered to be complete and the source is trusted.
[0097] The technical solution provided in this embodiment uses an encryption algorithm and a signature algorithm to double encrypt the password update broadcast, thereby ensuring the security of the password update broadcast and improving the security of the Mesh network.
[0098] Figure 4 A flow chart of another Mesh password update method provided in an embodiment of the present application is shown. For the sake of convenience, only the part related to the present embodiment is shown. The method provided in the present embodiment is applied to the device side, the device side is connected to the BLE control module for communication, and the BLE control module is connected to the Mesh network for communication. As an example, the device side, the BLE control module and the Mesh network can be respectively Figure 1 The device end 130, the BLE control module 120 and the Mesh network 110 in the Mesh password update system 100 shown in the figure, the method provided in this embodiment includes the following steps:
[0099] S410, obtaining a target broadcast frequency and a target Mesh password.
[0100] In a specific implementation, the device side has a user interaction interface, and the device side with management authority obtains the target broadcast frequency and the target Mesh password through the user interaction interface.
[0101] Exemplarily, the user interaction interface in the device side is a touch screen, and the device side with management authority obtains the target broadcast frequency and target Mesh password input by the user through the touch screen.
[0102] Exemplarily, a specific application is provided in the device end, and communication with the BLE control module is performed through the specific application.
[0103] S420, generate password update configuration information using the target broadcast frequency and the target Mesh password, and send the password update configuration information to the BLE control module; so that the BLE control module sends a password update broadcast to the Mesh network based on the target broadcast frequency, and the password update broadcast carries the target Mesh password; the target Mesh node in the Mesh network receives the password update broadcast through the BLE module, updates the password based on the target Mesh password, and synchronizes the target Mesh password to other Mesh nodes in the Mesh network; the target Mesh node is any Mesh node in the Mesh network.
[0104] In a specific implementation, the device generates password update configuration information based on the acquired target broadcast frequency and target Mesh password, and sends the password update configuration information to the BLE control module.
[0105] As an example, before sending the password update configuration information to the BLE control module, the device sends a password management enable instruction to the BLE control module, so that the BLE control module forwards the password management enable instruction to the target Mesh node, and the target Mesh node enables the password management function based on the password management enable instruction.
[0106] As an example, the device sends password update configuration information to the BLE control module based on the acquired target broadcast frequency, and the password update configuration information only includes a target Mesh password; so that the BLE control module immediately sends the target Mesh password to the Mesh network after receiving the password update configuration information.
[0107] As an example, the password update configuration information sent by the device to the BLE control module includes a target Mesh password and a target broadcast frequency, so that the BLE control module sends a password update broadcast carrying the target Mesh password to the Mesh network based on the target broadcast frequency.
[0108] As an example, the password update configuration information sent by the device to the BLE control module includes multiple target Mesh passwords and a target broadcast frequency, so that the BLE control module generates corresponding password update broadcasts according to each target Mesh password, and sends each password update broadcast to the Mesh network in turn according to the target broadcast frequency.
[0109] As an example, the password update configuration information sent by the device to the BLE control module includes multiple target Mesh passwords and target broadcast frequencies corresponding to each target Mesh password, so that the BLE control module generates corresponding password update broadcasts according to each target Mesh password, and then sends each password update broadcast to the Mesh network in turn according to the target broadcast frequency corresponding to each target Mesh password.
[0110] As an example, the device sends a password management shutdown instruction to the BLE control module, so that the BLE control module forwards the password management shutdown instruction to the target Mesh node, and the target Mesh node shuts down the password management function based on the password management shutdown instruction.
[0111] In the technical solution provided in this embodiment, the device with management authority obtains the target broadcast frequency and the target Mesh password, and sends the password update configuration information including the target broadcast frequency and the target Mesh password to the BLE control module, so that the BLE control module sends the password update broadcast to the Mesh network based on the target broadcast frequency, and each Mesh node in the Mesh network updates the current Mesh password to the target Mesh password according to the target broadcast frequency, thereby improving the security of the Mesh network.
[0112] Figure 5 A timing diagram of a Mesh password update method provided in an embodiment of the present application, combined with Figure 5 As shown, based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. As an example, the Mesh network, the target Mesh node, the BLE control module and the device end in this embodiment can be respectively Figure 1 The Mesh network 110, Mesh node 111, BLE control module 120 and device end 130 in the Mesh password update system 100 are shown. Specifically, the method provided in this embodiment includes:
[0113] The BLE control module performs authentication connection with the device end;
[0114] After completing the authentication connection, the BLE control module determines the permissions of the device.
[0115] When the device has application permission, the BLE control module receives the Mesh password request message sent by the device, and sends the current Mesh password of the Mesh network to the device based on the Mesh password request message; the device establishes a communication connection with the target Mesh node in the Mesh network based on the current Mesh password of the Mesh network;
[0116] When the device has management authority, the device sends a password management enable command to the BLE control module, and the BLE control module sends a password management enable broadcast carrying the password management enable command to the Mesh network. The target Mesh node in the Mesh network enables the password management function based on the password management enable command.
[0117] The device obtains the target broadcast frequency and target Mesh password, generates password update configuration information using the target broadcast frequency and target Mesh password, and sends the password update configuration information to the BLE control module; the BLE control module uses encryption and signature algorithms to encrypt the password update broadcast carrying the target Mesh password, and sends the encrypted password update broadcast to the Mesh network based on the target broadcast frequency, and the encrypted password update broadcast carries the target Mesh password;
[0118] The target Mesh node in the Mesh network decrypts the encrypted password update broadcast to obtain the target Mesh password; compares the target Mesh password with the current Mesh password, and when the target Mesh password is different from the current Mesh password, uses the target Mesh password to update the current Mesh password;
[0119] The target Mesh node in the Mesh network synchronizes the target Mesh password to other Mesh nodes in the Mesh network.
[0120] The technical solution provided in this embodiment adds multiple layers of security protection. Only the device with management authority can set the password update configuration information. The BLE control module and the device need to be connected for authentication. The password update broadcast uses an encryption algorithm and a signature algorithm for double encryption, ensuring the security of the Mesh network password update.
