Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) technology, and in particular to a communication method, system, device, and medium for IoT devices. Background Technology

[0002] With the development of science and technology, the Internet of Things (IoT) (such as the power IoT and the industrial IoT) has developed rapidly. In IoT systems, a large number of different types of IoT devices (such as distribution IoT devices in the power IoT) communicate, generate, process, and transmit data through IoT networks. Data communication and transmission of IoT devices has become a key focus for relevant professionals.

[0003] Currently, the relevant technology typically involves allocating frequency band usage time slots for data to be transmitted based on the amount of data transmitted by IoT devices in an IoT system, and then transmitting the data to the server in the IoT system based on the allocated usage time slots. However, as the number of IoT devices connected to the IoT system continues to increase, and the number of IoT devices transmitting data also continues to increase, this method is prone to resource contention during data communication transmission, and the stability and reliability of IoT device data communication transmission are not satisfactory.

[0004] Therefore, the problems with the relevant technologies still need to be solved and optimized. Summary of the Invention

[0005] The purpose of this invention is to at least partially solve one of the technical problems existing in the related art.

[0006] Therefore, one objective of this invention is to provide a communication method, system, apparatus, and medium for Internet of Things (IoT) devices, wherein the method can effectively improve the communication stability and reliability of IoT devices.

[0007] To achieve the above-mentioned technical objectives, the technical solutions adopted in the embodiments of this application include:

[0008] In a first aspect, embodiments of this application provide a communication method for an Internet of Things (IoT) device, applied to an IoT gateway, wherein the IoT gateway is communicatively connected to an IoT server, and the method includes:

[0009] Obtain the IoT communication mode set, as well as the configuration parameters, historical transmission data records, and data to be transmitted of the IoT device, wherein the data to be transmitted includes device data of several different data types;

[0010] Based on the IoT communication mode set, a communication strategy is generated for the configuration parameters and the historical transmission data records to obtain a parallel communication strategy. The parallel communication strategy includes several target communication modes, each of which corresponds to at least one type of device data. Different target communication modes correspond to different data types.

[0011] The parallel communication strategy is used to generate a key to obtain a communication key group. The communication key group includes several mode keys, each mode key corresponds to a target communication mode, and the several mode keys in the communication key group are different from each other and have an association relationship.

[0012] According to the communication key group and the parallel communication strategy, the data to be transmitted by the IoT device is transmitted in parallel to the IoT server.

[0013] In addition, the method according to the above embodiments of this application may also have the following additional technical features:

[0014] Furthermore, in one embodiment of this application, the step of generating a communication strategy based on the configuration parameters and the historical transmission data records according to the IoT communication mode set to obtain a parallel communication strategy includes:

[0020] Based on all the transmission sequence information, key associations are constructed for all the mode responses to obtain the communication key group.

[0021] Furthermore, in one embodiment of this application, obtaining the mode response of the IoT device in each of the target communication modes includes:

[0023] The pattern challenge is sent to the IoT device so that the IoT device generates a response to the pattern challenge, and the pattern response returned by the IoT device is obtained.

[0024] Furthermore, in one embodiment of this application, the step of constructing the communication key group by performing key association on all the mode responses based on all the transmission sequence information includes:

[0025] Get the current round, the current transmission sequence information, and the mode response;

[0026] Perform round analysis on the current round to obtain the round analysis results;

[0027] If the round analysis result indicates that the current round is the first round, then the current transmission sequence information and mode response are concatenated using a first key to obtain a mode key corresponding to the current round; or, if the round analysis result indicates that the current round is not the first round, then an intermediate key is obtained, and based on the intermediate key, the current transmission sequence information and mode response are concatenated using a second key to obtain a mode key corresponding to the current round.

[0028] The intermediate key is the pattern key from the previous round.

[0029] Furthermore, in one embodiment of this application, the step of concatenating the current transmission sequence information and the pattern response with a first key to obtain the pattern key corresponding to the current round includes:

[0030] The current transmission sequence information and the mode response are concatenated to obtain the first concatenated data;

[0031] The first concatenated data is subjected to key hashing to obtain the pattern key.

[0032] Further, in one embodiment of this application, the step of concatenating the current transmission sequence information and the pattern response with a second key based on the intermediate key to obtain the pattern key corresponding to the current round includes:

[0033] Based on the intermediate key, the current mode response is XORed and combined to obtain composite key response data;

[0034] Based on the composite key response data, the current transmission sequence information is concatenated to obtain the second concatenated data;

[0035] The second concatenated data is subjected to key hashing to obtain the pattern key.

[0036] Secondly, embodiments of this application provide a communication system for an Internet of Things (IoT) device, applied to an IoT gateway, wherein the IoT gateway is communicatively connected to an IoT server, and the system includes:

[0037] The first processing unit is used to acquire a set of IoT communication modes, as well as the configuration parameters, historical transmission data records and data to be transmitted of the IoT device. The data to be transmitted includes device data of several different data types.

The parallel communication strategy includes several target communication modes, each of which corresponds to at least one type of device data. Different target communication modes correspond to different data types.

[0039] The third processing unit is used to generate a key for the parallel communication strategy to obtain a communication key group. The communication key group includes several mode keys, each mode key corresponds to a target communication mode, and the several mode keys in the communication key group are different from each other and have an association relationship.

Different target communication modes correspond to different data types. A key is generated from the parallel communication strategy to obtain a communication key group. The communication key group includes several mode keys, each corresponding to one target communication mode. The mode keys within the communication key group are different but related. Based on the communication key group and the parallel communication strategy, the data to be transmitted from the IoT device is transmitted in parallel to the IoT server.

It should be understood that the accompanying drawings described below are only for the purpose of clearly illustrating some embodiments of the technical solutions in this application. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.

[0051] Figure 3 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Detailed Implementation

[0052] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. The step numbers in the following embodiments are set only for ease of explanation, and there is no limitation on the order between the steps. The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0054] Currently, the relevant technologies typically allocate frequency band usage time slots for data to be transmitted in IoT systems based on the amount of data transmitted by IoT devices, and then transmit the data to the server in the IoT system based on the allocated usage time slots, thereby suppressing the high packet loss rate during data communication transmission in IoT systems. However, with the continuous increase in the number of IoT devices connected to the IoT system and the continuous increase in the number of IoT devices transmitting data, this method is prone to resource contention during data communication transmission, and the stability and reliability of IoT device data communication transmission are not satisfactory.

[0055] Furthermore, related technologies typically involve adding authentication functionality for the device's private or public key within the IoT system. After successful authentication, a connection is established, and data to be transmitted is communicated over this connection based on time slots. However, public keys are not very secure, and private keys require IoT devices to possess substantial computing resources. In practical IoT applications, where the resources of IoT devices are often extremely limited, this approach suffers from poor security and is not suitable for resource-constrained IoT devices, thus limiting its applicability.

[0056] It should be noted that the aforementioned related technologies are only used to assist in understanding the technical solutions of this application and do not mean that they belong to the publicly disclosed prior art.

[0057] In view of this, embodiments of this application provide a communication method, system, apparatus, and medium for IoT devices. The method includes a parallel communication strategy comprising several target communication modes and a mode key corresponding to each target communication mode, to transmit data in parallel. Specifically, based on the parallel communication strategy and the mode key corresponding to each target communication mode, device data of several data types corresponding to each target communication mode are transmitted in parallel to the IoT service. This can suppress resource contention during data communication transmission while ensuring secure data transmission, thereby effectively improving the communication stability and reliability of IoT devices.

[0058] Furthermore, this method generates target communication modes and mode keys corresponding to the device data of IoT devices on the IoT gateway side, which can reduce the resource requirements of IoT devices and improve the applicability. Also, based on the fact that several mode keys within a communication key group are different yet related, specifically by concatenating the mode response of the current target communication mode with the mode key of the previous target communication mode, this method ensures that the mode key of each target communication mode under the IoT device is not completely identical to and related to the mode keys of other target communication modes. These different yet related mode keys allow the IoT gateway to notify the IoT device to continue secure data transmission using the keys of the remaining target communication modes after discovering that the mode key of one of the target communication modes of the IoT device has been attacked, thus improving the security of data communication transmission.

[0059] Reference Figure 1 In this embodiment of the application, a communication method for an Internet of Things (IoT) device is applied to an IoT gateway, wherein the IoT gateway is communicatively connected to an IoT server, and the method includes:

[0060] Step 110: Obtain the IoT communication mode set, as well as the configuration parameters, historical transmission data records and data to be transmitted of the IoT device. The data to be transmitted includes device data of several different data types.

[0061] In the embodiments of this application, the IoT communication mode set can be a collection of various different types of communication modes in the IoT system. For example, in the power IoT system, the commonly used communication modes are high-speed power line carrier communication mode and low-power wireless communication mode. The IoT communication mode set of the power IoT system can include high-speed power line carrier communication mode and low-power wireless communication mode.

[0062] Understandably, in an IoT system, an IoT gateway can communicate with multiple IoT devices and with an IoT server. Specifically, for one of the IoT devices under the IoT gateway, the gateway can obtain configuration parameters previously provided by the gateway. These parameters include at least one of the IoT device's communication power consumption, bandwidth, latency, and operating frequency band. Historical transmission data records can be the data transmission records of the IoT device in previous historical time periods, recording the amount of data transmitted and the data transmission requirements for each time period. The data to be transmitted can be the data that the IoT device is currently preparing to transmit. This data includes several different types of device data. For example, for an IoT device used for alarms in an IoT system, the data it needs to transmit includes fault data and remaining battery power data, with the data types of the fault data and the remaining battery power data being different.

[0063] Step 120: Based on the IoT communication mode set, generate a communication strategy for the configuration parameters and the historical transmission data records to obtain a parallel communication strategy;

[0064] In this embodiment of the application, for any IoT device that is connected to the IoT gateway, the IoT gateway can determine the parallel communication strategy corresponding to the IoT device based on the configuration parameters and historical transmission data records of the IoT device. The parallel communication strategy includes several target communication modes, each target communication mode corresponds to at least one type of device data, and different target communication modes correspond to different data types.

[0065] In some embodiments, the step of generating a communication strategy based on the configuration parameters and the historical transmission data records according to the IoT communication mode set to obtain a parallel communication strategy includes:

[0066] Based on the configuration parameters, the IoT communication mode set is analyzed to obtain several available modes;

[0067] Based on all the available modes, the historical transmission data records are assigned data modes to obtain several data types corresponding to each available mode;

[0068] Based on all the data types, the corresponding available modes are mapped and combined to obtain the parallel communication strategy.

[0069] In this embodiment, for any IoT device's configuration parameters, mode analysis can determine the available modes of the IoT device from the IoT communication mode set based on the device power consumption in the configuration parameters. For example, it can determine the available modes for devices supporting high power consumption as high-speed power line carrier communication mode and low-power wireless communication mode, and determine the available mode for devices supporting only low power consumption as low-power wireless communication mode. Alternatively, it can determine the available modes of the IoT device from the IoT communication mode set based on the frequency band used in the configuration parameters.

[0070] It is understood that, taking an IoT device for alarm purposes as an example, if the available modes of the IoT device for alarm purposes include high-speed power line carrier communication mode and low-power wireless communication mode, the data mode allocation can first be based on the historical transmission data records of the IoT device for alarm purposes to determine the data type. For example, the real-time transmission data type can be determined based on the fault data that needs to be reported in real time in the historical transmission data records, and the timed reporting data type can be determined based on the remaining battery power data of the device that only needs to be reported periodically. Alternatively, the data type division can also be determined based on the amount of transmission data in the historical transmission data records. There are already many ways to determine the specific data type, which will not be elaborated here.

[0071] It is worth mentioning that after determining the data type of the IoT device used for alarm, for example, if the IoT device used for alarm includes real-time transmission and timed reporting types, an available mode can be assigned to the determined data type. For example, the high-speed power line carrier communication mode can correspond to the real-time transmission data type, while the low-power wireless communication mode can correspond to the timed reporting data type. Based on each available mode and the data type corresponding to each available mode, a target communication mode is generated, and then a parallel communication strategy is constructed based on all target communication modes.

[0072] It should be noted that, for ease of understanding, the examples provided in this application are only simple examples. In practical applications, each available mode may correspond to multiple different types of device data. For example, the high-speed power line carrier communication mode may also correspond to multiple data types such as "real-time transmission" and "large data transmission volume". This application will not elaborate further here.

[0073] Step 130: Generate a key for the parallel communication strategy to obtain a communication key group. The communication key group includes several mode keys, and each mode key corresponds to a target communication mode.

[0074] In this embodiment of the application, key generation may be to generate a corresponding mode key for each target communication mode in the parallel communication strategy, and to construct a communication key group based on the mode key in each target communication mode, wherein each mode key in the communication key group is different and has an association relationship.

[0075] In some embodiments, generating a communication key set for the parallel communication strategy includes:

[0076] Acquire the transmission sequence information for each of the target communication modes, and the mode response of the IoT device under each of the target communication modes;

[0077] Further, obtaining the mode response of the IoT device in each of the target communication modes includes:

[0078] Based on the target communication mode, a mode challenge is obtained, and the mode challenge is different under different target communication modes;

[0079] The pattern challenge is sent to the IoT device so that the IoT device generates a response to the pattern challenge, and the pattern response returned by the IoT device is obtained.

[0080] In this embodiment, the transmission sequence information is used to indicate the position of the device data corresponding to the target communication mode within the entire data to be transmitted, and it can be determined based on the historical transmission data records of the IoT device. For the pattern response of the IoT device in any target communication mode, it can generate a random challenge, denoted as the pattern challenge, through the IoT gateway in the target communication mode based on challenge-response authentication technology, and send the pattern challenge to the IoT device, so that the IoT device can generate and return a pattern response to the IoT gateway based on its own configured Physically Unclonable Response (PUF) module in the target communication mode.

[0081] Based on all the transmission sequence information, key associations are constructed for all the mode responses to obtain the communication key group.

[0082] Further, the step of constructing the communication key set by key association of all the mode responses based on all the transmission sequence information includes:

[0083] Get the current round, the current transmission sequence information, and the mode response;

[0084] Perform round analysis on the current round to obtain the round analysis results;

[0085] In this embodiment of the application, for any IoT device that is connected to the IoT gateway, the IoT gateway can generate a mode key corresponding to each target communication mode of the parallel communication strategy in a cyclical manner based on the parallel communication strategy corresponding to the IoT device.

[0086] It is understandable that the current round can be the current execution round in the loop process, the current transmission sequence information can be the transmission sequence information of the target communication mode corresponding to the current round, and the current mode response can be the mode response of the target communication mode corresponding to the current round.

[0087] For example, in this embodiment of the application, the target communication modes of the IoT device used for alarms are high-speed power line carrier communication mode and low-power wireless communication mode, respectively, with high-speed power line carrier communication mode corresponding to the first round and low-power wireless communication mode corresponding to the second round. Round analysis can be performed to analyze and determine whether the current round belongs to the first round, thereby obtaining the first round. Specifically, if the round analysis result is that the current round is the first round, it means that the mode key of the current round is the first mode key generated by the IoT gateway for the IoT device, that is, the IoT gateway generates the mode key for the high-speed power line carrier communication mode of the IoT device; or, if the current round is the second round, the round analysis result is that the current round is not the first round, which means that the mode key of the current round is the second mode key generated by the IoT gateway for the IoT device, that is, the IoT gateway generates the mode key for the low-power wireless communication mode of the IoT device.

[0088] It should be noted that the example of the current round in this application is only a simple example. In actual applications, there are more than or equal to 3 target communication modes of IoT devices. In this case, the maximum round threshold of the current round is equal to the total number of target communication modes. This application will not elaborate further here.

[0089] If the round analysis result indicates that the current round is the first round, then the current transmission sequence information and the mode response are concatenated with a first key to obtain the mode key corresponding to the current round;

[0090] Further, the step of concatenating the current transmission sequence information and the pattern response with a first key to obtain the pattern key corresponding to the current round includes:

[0091] The current transmission sequence information and the mode response are concatenated to obtain the first concatenated data;

[0092] The first concatenated data is subjected to key hashing to obtain the pattern key.

[0093] In this embodiment, if the first round is applied to the high-speed power line carrier communication mode of the IoT device used for alarm, the first key splicing can first be achieved by splicing the transmission sequence information in the high-speed power line carrier communication mode and the mode response returned by the IoT device used for alarm in the high-speed power line carrier communication mode through the IoT gateway, thereby obtaining the first spliced ​​data; then, the IoT gateway performs a hash operation on the obtained first spliced ​​data, thereby generating the mode key of the IoT device used for alarm in the high-speed power line carrier communication mode.

[0094] For example, the pattern key in the first round can be represented as:

[0095] h1=H(δ1||s1)

[0096] Where h1 is the mode key in the first round; H(·) is the hash operation function; δ1 is the mode response of the target communication mode corresponding to the first round; and s1 is the transmission sequence information of the target communication mode corresponding to the first round.

[0097] Alternatively, if the round analysis result indicates that the current round is not the first round, then an intermediate key is obtained, and based on the intermediate key, the current transmission sequence information and the mode response are concatenated with a second key to obtain the mode key corresponding to the current round.

[0098] Further, the step of concatenating the current transmission sequence information and the pattern response with a second key based on the intermediate key to obtain the pattern key corresponding to the current round includes:

[0099] Based on the intermediate key, the current mode response is XORed and combined to obtain composite key response data;

[0100] Based on the composite key response data, the current transmission sequence information is concatenated to obtain the second concatenated data;

[0101] The second concatenated data is subjected to key hashing to obtain the pattern key.

[0102] In this embodiment of the application, taking the current round as the second round, and taking the low-power wireless communication mode of the IoT device used for alarm as an example, the second key concatenation can be as follows: obtaining the mode key of the first round, that is, the mode key of the IoT device used for alarm in high-speed power line carrier communication mode, denoted as the intermediate key; then, performing an XOR operation between the intermediate key and the mode response of the IoT device used for alarm in low-power wireless communication mode to obtain composite key response data; and concatenating the composite key response data with the transmission sequence information of the IoT device used for alarm in low-power wireless communication mode, and performing a hash operation on the concatenated second concatenated data to obtain the mode key of the IoT device used for alarm in low-power wireless communication mode.

[0103] For example, the pattern key in the second round can be represented as:

[0104]

[0105] Where h2 is the mode key in the second round; H(·) is the hash function; δ2 is the mode response of the target communication mode corresponding to the second round; and s2 is the transmission sequence information of the target communication mode corresponding to the second round.

[0106] It is understandable that in actual IoT application scenarios, the target communication mode of the IoT device connected to the IoT gateway is one or more. For cases where the target communication mode of the IoT device is one, two or more, it can be simply deduced based on the aforementioned example of this application, and will not be elaborated further here.

[0107] Step 140: Based on the communication key group and the parallel communication strategy, transmit the data to be transmitted from the IoT device to the IoT server in parallel.

[0108] In this embodiment, after generating a communication key group and parallel communication strategy corresponding to the IoT device, the IoT gateway can transmit the data to be transmitted from the IoT device to the IoT server in parallel based on the obtained communication key group and parallel communication strategy.

[0109] Specifically, if the IoT device is used for alarm purposes, the IoT gateway can first split the data to be transmitted from the user's alarm IoT device into fault data and remaining battery power data. Then, based on the mode key corresponding to the high-speed power line carrier communication mode, the fault data is encrypted to obtain fault encrypted data, and based on the mode key corresponding to the low-power wireless communication mode, the remaining battery power data is encrypted to obtain battery encrypted data. Then, the IoT gateway transmits the fault encrypted data based on the high-speed power line carrier communication mode and transmits the battery encrypted data based on the low-power wireless communication mode, thereby transmitting the data to be transmitted from the alarm IoT device to the IoT server in parallel.

[0110] Understandably, during the transmission of data, the IoT gateway can also monitor the bandwidth utilization of the frequency band used by each target communication mode in real time. Specifically, for a certain target communication mode, when the bandwidth utilization of a certain frequency band used under that target communication mode is greater than a first preset threshold, the data to be transmitted under that frequency band can be split, and the split data can be transmitted using the remaining frequency bands where the bandwidth utilization of the target communication mode is less than or equal to a second preset threshold. This ensures load balancing in the IoT system, helps avoid frequent packet loss due to excessive load, and further improves the communication stability and reliability of IoT devices.
