[0053] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0054] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0055] The following embodiments of the present application provide a wireless sensor communication control method and system, a communication system, a medium, and a terminal. Through a dynamic whitelist broadcast mechanism, the number of broadcasts can be greatly reduced, and power consumption can be reduced. At the same time, using a whitelist address to notify the switching of service modes can achieve a quick response and reduce coupling.

[0056] See also Figure 1 , which shows a schematic diagram of an implementation scenario of the wireless sensor communication control method described in an embodiment of the present application, for a tire pressure monitoring system for an automobile. The tire pressure monitoring system 100 includes: an integrated pressure sensor 110, a gateway 120, and an onboard control unit 130.

[0057] After the integrated pressure sensor 110 establishes a communication connection with the gateway 120, the integrated pressure sensor 110 broadcasts the collected tire pressure data according to the initial broadcast frequency;

[0058] The gateway 120 uploads the received tire pressure data to the on-board control unit 130. When the received tire pressure data is detected to be abnormal, the on-board control unit 130 triggers a real-time alarm and sends a scan of the diagnostic address to the integrated pressure sensor 110 through the gateway 120 to trigger the integrated pressure sensor 110 to perform real-time tire pressure data detection and broadcast, as well as firmware update instructions.

[0059] The rapid development of the Internet of Things (IoT) has enabled the widespread application of wireless sensor networks in areas such as environmental monitoring, smart homes, and industrial automation. However, these networks face numerous challenges in security authentication, communication efficiency, and energy management. In resource-constrained environments, ensuring communication security while reducing energy consumption is a critical issue that needs to be addressed.

[0060] While currently used complex encryption algorithms and authentication mechanisms improve communication security, they also increase system complexity and energy consumption. Furthermore, in traditional wireless sensor networks, sensor nodes are frequently woken up to broadcast data and receive notifications from edge gateway devices, which not only consumes a lot of energy but can also lead to communication delays and conflicts.

[0061] At least to address the above-mentioned problems, the present application provides a wireless sensor communication control method and system, a communication system, a medium and a terminal, which switches the service mode of the sensor node by using the generated whitelist address notification; uses a periodically updated random factor to periodically update the whitelist address list to effectively resist address spoofing and replay attacks; and a dynamic whitelist broadcast mechanism to reduce complex encryption calculation processes, greatly reduce the number of broadcasts, and reduce power consumption.

[0062] The principles and implementation methods of the wireless sensor communication control method and system, communication system, medium, and terminal of this embodiment will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can understand the wireless sensor communication control method and system, communication system, medium, and terminal of this embodiment without creative work.

[0063] See also Figure 2 , which shows a flow chart of the wireless sensor communication control method provided by the embodiment of the present application. Figure 2 As shown, the process includes the following steps S1 to S3.

[0064] Step S1: Obtain a shared key, a device address of a sensor node, and a random factor, and generate a whitelist address list based on the shared key, the device address, and the random factor. In this embodiment, the whitelist address list includes: a connectable whitelist address and a service address.

[0065] Step S2: broadcast the random factor to the gateway device, so that the gateway device calculates and obtains the whitelist address list according to the scanned random factor.

[0066] Step S3: Based on the connectable whitelist address in the whitelist address list, the gateway device establishes a connection with the sensor node, and controls switching of the service mode of the sensor node through the service address in the whitelist address list.

[0067] In this embodiment, the random factor is generated periodically, the whitelist address list is updated periodically based on the periodically generated random factor, and the random factor is broadcast periodically.

[0068] Specifically, a whitelist address list is generated and updated based on the updated random factor calculation, and the updated random factor is broadcast to the gateway device according to the broadcast interval, so that the gateway device obtains the updated whitelist address list based on the scanned updated random factor calculation, and establishes a connection with the sensor node through the connectable whitelist address in the updated whitelist address list, and controls the switching of the service mode of the sensor node through the service address in the updated whitelist address list.

[0069] In step S1, a whitelist address list is generated based on the shared key, the device address and the random factor, including: encrypting the device address and the random factor to obtain a 128-bit ciphertext; processing the shared key, the random factor and the 128-bit ciphertext through a hash algorithm to obtain a message authentication code; and splitting the message authentication code to obtain a whitelist address list.

[0070] like Figure 3 FIG. 1 is a flowchart of obtaining a whitelist address list according to this embodiment.

[0071] In this embodiment, the random factor is randomly generated by a random number generator, and the random factor and the device address are encrypted by the AES_128_ECB encryption method to obtain a 128-bit ciphertext. The 128-bit ciphertext, the random factor and the shared key are combined by a hash algorithm to generate an HMAC value of a fixed length, and the fixed-length HMAC value is mapped and output as a hash value of a fixed length to obtain a message authentication code. The message authentication code is split based on preset rules to obtain a whitelist address list.

[0072] Preferably, the random factor is an 8-bit random number.

[0073] Preferably, the 128-bit ciphertext, the random factor and the shared key are combined through HMAC-SHA256 (Hash-based Message Authentication Code using SHA-256) to generate a 256-bit HMAC value, and then the 256-bit HMAC value is mapped and output as a 256-bit hash value, i.e., a 256-bit message authentication code, through 256bit HASH (256-bit hash function).

[0074] In this embodiment, the preset rule is: split the 256-bit message authentication code into four 48-bit addresses, take the first 48-bit address as the connectable whitelist address, and take the last three 48-bit addresses as the service addresses. Specifically, the service addresses include: collection address, diagnosis address, and ranging address.

[0075] In step S2, the gateway device calculates and obtains the whitelist address list according to the scanned random factor, including: obtaining the device address based on the scanned random factor; and generating the whitelist address list according to the random factor, the device address and the obtained shared key.

[0076] In this embodiment, the gateway device obtains the whitelist address list based on the same algorithm, and the whitelist address list obtained based on the same random factor is unique.

[0077] In step S3, the service address includes: a collection address, a diagnostic address, and a ranging address. Controlling the switching of the service mode of the sensor node using the service address in the whitelist address list includes: sending a collection address instruction according to the collection address to trigger the sensor node to broadcast the real-time collected environmental data; sending a diagnostic address instruction according to the diagnostic address to trigger the sensor node to upload a self-test log and / or receive a firmware update; and sending a ranging address instruction according to the ranging address to trigger the positioning function of the sensor node to implement a location tracking function.

[0078] In this embodiment, the gateway device initiates a connection request to the sensor node using the obtained connectable whitelist address, and the sensor node establishes a communication connection with the gateway device based on the same whitelist address.

[0079] In some implementations, if the gateway device is not bound to the sensor node that requires a communication connection, the gateway device calculates a whitelist address list based on the random factor broadcast by the scanned sensor node, and uses the connectable whitelist address therein to initiate a connection request and a business instruction to the sensor node; if the gateway device is bound to the sensor node that requires a communication connection, the gateway device initiates a connection request and a business instruction to the sensor node based on the saved connectable whitelist address corresponding to the sensor node.

[0080] See also Figure 4 , which is a schematic diagram of the structure of a wireless sensor communication control system provided by an embodiment of the present application. The wireless sensor communication control system 400 includes: a sensor node 410 and a gateway device 420.

[0081] In this embodiment, the sensor node 410 is configured to obtain a shared key, a device address of the sensor node and a random factor, and generate a whitelist address list based on the shared key, the device address and the random factor; the whitelist address list includes: a connectable whitelist address and a business address; and broadcast the random factor to the gateway device.

[0082] The gateway device 420 is configured to calculate and obtain the whitelist address list based on the received random factor; and establish a connection with the sensor node based on the connectable whitelist address in the whitelist address list, and control the switching of the service mode of the sensor node through the service address in the whitelist list.

[0083] The sensor node 410 is further configured to periodically generate the random factor.

[0084] like Figure 5The figure shows a schematic diagram of a sensor node in an activated state and a bound state.

[0085] In some implementations, the connection state of the sensor node includes a bound state and an unbound state.

[0086] When the sensor node is in an unbound state, the gateway device calculates and obtains a whitelist address list according to a random factor broadcast by the sensor node, establishes a connection with the sensor node through a connectable whitelist address list in the whitelist address list, and controls switching of the service mode of the sensor node through the service address in the whitelist list;

[0087] When the sensor node is in a bound state, the gateway device directly establishes a connection with the sensor node according to the connectable whitelist in the stored whitelist address list, and controls the switching of the service mode of the sensor node through the service address in the whitelist.

[0088] If the gateway device has obtained the connectable whitelist address of the target-bound sensor node, it can autonomously scan the target-bound sensor node through the connectable whitelist address and establish a connection with the target-bound sensor node.

[0089] In some implementations, the working state of the sensor node includes: an activated state and an inactivated state.

[0090] When the sensor node does not broadcast or broadcasts at a low speed, the sensor node is in an inactive state;

[0091] For sensor nodes whose data collected in factory and operating states show no significant difference, they need to be actively activated at workstations where significant changes occur during the production process. For example, if a temperature sensor is in a high-temperature aging test bench, it will automatically activate if it receives continuous high-temperature data exceeding a threshold. If the sensor node is a pressure or speed sensor, it will automatically activate based on the collected pressure or speed data after installation.

[0092] In this embodiment, the activated sensor node broadcasts a random factor according to the activation strategy.

[0093] In some implementations, the sensor node broadcasts the random factor according to a broadcast strategy.

[0094] Specifically, the sensor node broadcasts the random factor according to the broadcast interval. If a scan notification of a whitelist address in the whitelist address list of the corresponding gateway device is received, the sensor node will enter a different service mode:

[0095] If the sensor node is scanned by the connectable whitelist address, the sensor node establishes a communication connection with the gateway node and updates the stored data;

[0096] If the sensor node is scanned by the collection address, the sensor node broadcasts the environmental data collected in real time;

[0097] If the sensor node is scanned by the diagnostic address, the sensor node uploads a self-test log and / or receives a firmware update;

[0098] If the sensor node is scanned by the ranging address, the sensor node starts a positioning function to implement a position tracking function.

[0099] In this embodiment, if Figure 6 The figure shows a schematic diagram of the broadcast state transition of a sensor node. When a sensor node broadcasts real-time collected environmental data according to a broadcast interval, if it receives a scan notification from a whitelisted address of a gateway device, the sensor node assumes that the gateway device has received the real-time collected environmental data broadcast by the sensor node. The sensor node then enters a dormant state and switches to the corresponding service mode the next time it receives a scan notification from a whitelisted address of the gateway device.

[0100] It should be understood that the division of modules in the embodiments of the present application is illustrative and is merely a logical functional division. In actual implementation, other division methods may be used. Furthermore, the functional modules in the various embodiments of the present application may be integrated into a single processor, or may exist physically as separate modules, or two or more modules may be integrated into a single module. The aforementioned integrated modules may be implemented in the form of hardware or software functional modules.

[0108] The second storage module 770 is configured to store the whitelist address list and sensor binding information;

[0109] The interface module 780 is configured to communicate with an external network.

[0110] In this embodiment, the first data processing module 720 obtains a shared key, a device address of a sensor node, and a random factor, and generates a whitelist address list according to the shared key, the device address, and the random factor, and sends the whitelist address list to the first storage module 740 so that the first storage module 740 stores the whitelist address list; the first wireless radio frequency module 730 broadcasts the random factor according to a broadcast interval; the second wireless radio frequency module 760 receives the random factor so that the second data processing module 750 calculates and obtains the whitelist address list according to the received random factor, and stores the whitelist address list. The whitelist address list is sent to the second storage module 770 so that the second storage module 770 stores the whitelist address list; the second wireless RF module 760 scans according to the connectable whitelist address in the whitelist address list to send a communication connection request to the first wireless RF module 730, and the first wireless RF module 730 matches the connectable whitelist address corresponding to the received scanning notification of the second wireless RF module 760 with the connectable whitelist address in the whitelist address list stored in the first storage module 740 to establish a communication connection with the second wireless RF module 760 when the match is successful.

[0111] After establishing a communication connection with the first wireless RF module 730, the second wireless RF module 760 scans the business addresses in the whitelist address list according to the business requirements of the second data processing module 750 to send a business instruction to the first wireless RF module 730. After receiving the scanning notification of the corresponding business address, the first wireless RF module 730 switches the business mode of the sensor node through the first data processing module 720 to further control the data acquisition module 710.

[0112] In this embodiment, the random factor is generated periodically, the whitelist address list is updated periodically based on the periodically generated random factor, and the random factor is broadcast periodically.

[0113] Specifically, the first data processing module 720 periodically generates a random factor according to a preset period, and periodically updates the whitelist address list according to the random factor, and the first storage module 740 synchronously refreshes the stored whitelist address list to be the updated whitelist address list; after receiving the updated random factor, the second data processing module 750 calculates the corresponding updated whitelist address list, and the second storage module 770 synchronously refreshes the stored whitelist address list to be the updated whitelist address list.
