[0005] This method can reduce the situation where Internet of Things devices are restricted by the router and disconnected during communication. However, when the information of the Internet of Things device is tampered with, the target data may be modified, resulting in low data transmission security. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. The summary is not a comprehensive review, nor is it intended to identify key / important elements or delineate the scope of protection of these embodiments, but rather serves as a preface to the subsequent detailed description.

The request data is decrypted to obtain the target data that actually needs to be sent. The target data is placed in the priority sending queue to avoid interrupting the current data sending process and preventing the preemption of the data sending priority of other Internet of Things devices.

Since the blockchain system and the certificate can encrypt the target data to prevent tampering, the security of data transmission is improved while reducing the disconnection of the Internet of Things device.

[0033] In order to more comprehensively understand the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical descriptions, for the sake of explanation, numerous details are provided to give a thorough understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other instances, well-known structures and devices may be shown in a simplified manner to simplify the drawings.

[0034] In the specification, claims and above-mentioned drawings of the embodiments of the present disclosure, the terms "first", "second", etc. are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so as to implement the embodiments of the present disclosure described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0035] Unless otherwise specified, the term "plurality" means two or more.

[0036] In the embodiments of the present disclosure, the character " / " indicates that the objects before and after are in an "or" relationship. For example, A / B means: A or B.

[0037] The term "and / or" is a description of the associated relationship of objects and indicates that three relationships can exist. For example, A and / or B means: A or B, or, the three relationships of A and B.

[0038] The term "corresponding" may refer to an associated relationship or a binding relationship. A corresponding to B means that there is an associated relationship or a binding relationship between A and B.

[0039] At present, with the development of Internet of Things (IoT) technology, more and more IoT devices have entered people's lives, such as smart speakers, air conditioners, lights, water purifiers, etc. Users can control online IoT devices through terminal devices (such as mobile terminals). The commonly used method for determining whether an IoT device is online / offline is as follows: within a certain period of time, if the cloud server receives the heartbeat of the IoT device, it is considered that the IoT device is online. Within a certain period of time, if the cloud server does not receive the heartbeat of the IoT device, it is considered that the IoT device is offline. During the communication process between the IoT device and the cloud server, the router is used as the gateway to achieve data transmission.

[0040] As shown in Figure 1-1 When common IoT devices and non-IoT devices are connected to the router, they are connected through ordinary network protocols. When multiple connected devices (including IoT devices and non-IoT devices) send requests simultaneously, the router may experience network congestion problems, and data cannot be sent, resulting in the IoT device being considered offline. That is, although the IoT device is connected to the router, it is offline due to the limitations of the router.

[0041] As shown in Figure 1-2As shown in the figure, an embodiment of the present disclosure provides a connection method for an Internet of Things device and a non-Internet of Things device to a router. The non-Internet of Things device is connected to the router through a common network protocol, and the Internet of Things device is connected to the router through an anti-disconnection protection protocol. The anti-disconnection protection protocol includes a server and a client. The server is set in the router, and the client is set in the Internet of Things device. When multiple networked devices send requests simultaneously, the router puts the target data of the Internet of Things device into the priority sending queue according to the anti-disconnection protection protocol, and puts the target data of the non-Internet of Things device into the common sending queue according to the common network protocol. After the data in the priority sending queue is sent, the data in the common sending queue is sent, thereby reducing the possibility of the Internet of Things device dropping the line. Since there may be a problem that the target data is tampered with during the data transmission process. By adding a blockchain system and its distributed database to the router, the certificate for verifying the device type is stored in the distributed database. The server in the router is connected to the blockchain system and issues the certificate of the Internet of Things device to the blockchain system. The client in the Internet of Things device is connected to the blockchain system and obtains the certificate from the blockchain system. The Internet of Things device encrypts the target data through the certificate when sending the target data. When the router receives a data transmission request, it determines whether the device is an Internet of Things device by parsing the request data, and puts the target data obtained by decrypting the request data of the Internet of Things device into the priority sending queue. Since the blockchain system and the certificate can encrypt the target data to prevent tampering, the security of data transmission is improved while reducing the disconnection of the Internet of Things device. The connection method provided by the embodiment of the present disclosure can be realized only by the router and the Internet of Things device by updating their own firmware, without changing the hardware. For Internet of Things devices that do not require priority data transmission, the anti-disconnection protection protocol can be cancelled and regarded as non-Internet of Things devices.

[0042] Combined with Figure 2 As shown in the figure, an embodiment of the present disclosure provides a method for data transmission, including:

[0043] S220. When receiving a data transmission request, the router parses the request data.

[0044] S230. When it is determined that the request data carries a certificate issued by the blockchain system, the router determines that the device sending the data transmission request is an Internet of Things device.

[0045] S240. The router decrypts the request data to obtain the target data.

[0046] S250. The router puts the target data into the priority sending queue.

[0047] Using the method for data transmission provided by the embodiments of the present disclosure, when a router receives a data transmission request from a device, it parses the request data in the data transmission request to determine the information in the request data. When it is determined that the request data carries a certificate issued by a blockchain system, it is determined that the device sending the data transmission request is an Internet of Things device, and the data needs to be sent preferentially. The request data is decrypted to obtain the target data that actually needs to be sent. The target data is placed in a priority sending queue to avoid interrupting the current data sending process and prevent preempting the data sending priority of other Internet of Things devices. Since the target data of the Internet of Things device is placed in the priority sending queue, the sending priority of the target data is higher than that of non-Internet of Things devices, reducing the restriction of the router on the Internet of Things device during the communication process and thus reducing the possibility of the Internet of Things device dropping the line. Since the blockchain system and the certificate can encrypt and prevent tampering with the target data, the security of data transmission is improved while reducing the disconnection of the Internet of Things device.

[0048] Combined with Figure 3 As shown in the figure, the embodiments of the present disclosure provide another method for data transmission, including:

[0049] S221, when receiving a data transmission request, the router determines the set position of the certificate in the request data according to the anti-disconnection protection protocol.

[0050] S222, the router determines the data in the set position as the certificate information.

[0051] S223, the router determines whether the certificate information exists in the blockchain system.

[0052] S224, when the certificate information exists in the blockchain system, the router determines that the request data carries a certificate issued by the blockchain system.

[0053] S230, the router determines that the device sending the data transmission request is an Internet of Things device.

[0054] S241, the router determines the private key corresponding to the certificate carried in the request data.

[0055] S242, the router decrypts the request data through the private key to strip the certificate to obtain the target data.

[0056] S250, the router places the target data in the priority sending queue.

[0057] S251, when the target data is at the head of the priority sending queue, the router sends the target data to the corresponding network node.

[0058] S252, the router sends a data transmission request response to the Internet of Things device.

[0059] When using the method for data transmission provided by the embodiments of the present disclosure, in the case of receiving a data transmission request, according to the anti-disconnection protection protocol, the certificate information in the request data is determined. When the certificate information exists in the blockchain system, it is determined that the request data carries a certificate issued by the blockchain system, and the device sending the request data is an Internet of Things device. Since the request data contains a certificate, it is decrypted with the private key corresponding to the certificate (stored in the router) to obtain the target data to be actually sent. When the target data is at the head of the priority sending queue, the target data is sent to the corresponding network node and a data transmission request response is sent to the Internet of Things device, and the sending of the target data of the Internet of Things device is completed. Since the request data is encrypted data and needs to be decrypted before sending, the data transmission security is improved while reducing the disconnection of the Internet of Things device.

[0060] Combined with Figure 4 As shown in

[0061] S200, the router initializes the blockchain service.

[0062] S201, the router connects to the blockchain system.

[0063] S202, the router checks the validity periods of all certificates in the blockchain system.

[0064] S203, when it is determined that there are certificates whose validity periods meet the preset conditions, the router writes the alarm information of the Internet of Things device corresponding to the certificate into the blockchain system.

[0065] S210, when receiving a certificate application request sent by the blockchain system, the router determines the type of the application device according to the device information in the certificate application request.

[0066] S211, when the application device is an Internet of Things device, the router generates a certificate according to the device information.

[0067] S212, the router sends the certificate to the blockchain system.

[0068] S220, when receiving a data transmission request, the router parses the request data.

[0069] S230, when it is determined that the request data carries a certificate issued by the blockchain system, the router determines that the device sending the data transmission request is an Internet of Things device.

[0070] S240, the router decrypts the request data to obtain the target data.

[0071] S250, the router places the target data into the priority transmission queue.

[0072] Using the method for data transmission provided by the embodiments of the present disclosure, initialization is performed when starting to run, and connection is made with the blockchain system through the server. When the validity period of the certificate of an Internet of Things device in the blockchain system meets a preset condition, there is a risk that the certificate will expire, which may affect the data transmission of the corresponding Internet of Things device. By writing warning information into the blockchain system to remind the Internet of Things device, the possibility of the Internet of Things device going offline is reduced. When receiving a certificate application request sent by the blockchain system, there is a new device applying for anti-offline protection. When it is determined that the type of the device is an Internet of Things device, a certificate is generated according to the device information and sent to the blockchain system, so that the Internet of Things device carries the certificate when sending target data. Since a reminder is given when there is a risk of certificate expiration and verification is performed when the device applies for a certificate, the security of data transmission is improved.

[0073] For the determination in step S203 that there is a certificate whose validity period meets the preset condition, it is determined for the router that in the blockchain system, one or more certificates are about to expire or have expired.

[0074] Combined Figure 5 As shown, the embodiments of the present disclosure provide another method for data transmission, including:

[0075] S220, when receiving a data transmission request, the router parses the request data.

[0076] S230, when it is determined that the request data carries a certificate issued by the blockchain system, the router determines that the device sending the data transmission request is an Internet of Things device.

[0077] S240, the router decrypts the request data to obtain the target data.

[0078] S250, the router places the target data into the priority transmission queue.

[0079] S260, when receiving a certificate update request, the router generates a new certificate according to the device information in the certificate update request.

[0080] S261, the router sends the new certificate to the blockchain system.

[0081] S270, when receiving a certificate revocation request, the router determines the corresponding revoked certificate according to the device information in the certificate revocation request.

[0082] S271, the router deletes the revoked certificate from the blockchain system.

[0083] Using the method for data transmission provided by the embodiments of the present disclosure, when a certificate update request is received, there is a risk that the certificate of the Internet of Things device expires and a new certificate is required. A new certificate is generated based on the device information and sent to the blockchain system, improving the security of certificate issuance. When a certificate revocation request is received, the data of the Internet of Things device does not need to be sent preferentially. By deleting the revoked certificate from the blockchain system, the space occupied by the Internet of Things device in the blockchain system and the data transmission priority are reduced, improving the data transmission efficiency.

[0084] As shown in combination with Figure 6 Another method for data transmission provided by the embodiments of the present disclosure includes:

[0085] S320. When it is necessary to send target data, the Internet of Things device encrypts the target data using the certificate issued by the blockchain system to obtain request data.

[0086] S330. The Internet of Things device generates a data transmission request according to the request data.

[0087] S340. The Internet of Things device sends the data transmission request to the router.

[0088] Using the method for data transmission provided by the embodiments of the present disclosure, when the Internet of Things device needs to send target data, it encrypts the target data using the certificate issued by the blockchain system to obtain request data, and sends the data transmission request generated according to the request data to the router. Since the blockchain system and the certificate are used to encrypt the target data to prevent tampering, the data transmission security is improved while reducing the disconnection of the Internet of Things device.

[0089] As shown in combination with Figure 7 Another method for data transmission provided by the embodiments of the present disclosure includes:

[0090] S300. The Internet of Things device initializes the blockchain service.

[0091] S301. The Internet of Things device connects to the blockchain system.

[0092] S302. When in anti-disconnection protection, the Internet of Things device updates the device information in the blockchain system.

[0093] S303. When an alarm message is received, the Internet of Things device processes the alarm message and executes step S321.

[0094] S310. When it is necessary to apply for a certificate, the Internet of Things device sends the device information to the blockchain system.

[0095] S311. When receiving the application certificate response, the IoT device obtains the certificate from the blockchain system.

[0096] S321. When it is necessary to send the target data, the IoT device determines the set position of the certificate according to the anti-disconnection protection protocol.

[0097] S322. The IoT device adds the certificate to the target data according to the set position to obtain the request data.

[0098] S330. The IoT device generates a data transmission request according to the request data.

[0099] S340. The IoT device sends the data transmission request to the router.

[0100] Adopting the method for data transmission provided by the embodiment of the present disclosure, initialization is performed at the start of operation, and connection is made with the blockchain system through the client. When receiving the alarm information, there may be a risk of certificate expiration, and the alarm information is processed to determine that a prompt is received. When it is necessary to apply for a certificate, the device information is sent to the blockchain system so that the router generates the corresponding certificate. When the blockchain system determines that there is no certificate corresponding to the device information, it sends a certificate application request to the router. When receiving the application certificate response, the router has sent the generated certificate to the blockchain system, and the certificate is obtained from the blockchain system to improve the security of the certificate. When it is necessary to send the target data, the certificate is added to achieve encryption. Since the alarm information is received when there is a risk of certificate expiration, encryption is performed through the certificate when sending the target data to improve the security of data transmission.

[0101] Combined with Figure 8 As shown in the figure, the embodiment of the present disclosure provides another method for data transmission, including:

[0102] S320. When it is necessary to send the target data, the IoT device encrypts the target data using the certificate issued by the blockchain system to obtain the request data.

[0103] S330. The IoT device generates a data transmission request according to the request data.

[0104] S340. The IoT device sends the data transmission request to the router.

[0105] S350. The IoT device checks the validity period of the certificate.

[0106] S351. When it is determined that the validity period of the certificate meets the preset conditions, the IoT device sends a certificate update request to the router and deletes the certificate.

[0107] S352, The IoT device obtains a new certificate from the blockchain system.

[0108] S360, In the case where the certificate needs to be revoked, the IoT device sends a certificate revocation request to the router and deletes the certificate.

[0109] Using the method for data transmission provided by the embodiments of the present disclosure, when it is determined that the validity period of the certificate meets the preset conditions, there is a risk of certificate expiration, and a certificate update request is sent to the router to obtain a new certificate. In the case where the certificate needs to be revoked, the IoT device no longer needs to give priority to sending data, and sends a certificate revocation request to the router to reduce its own occupied priority, thereby improving the efficiency of data transmission.

[0110] For determining in step S351 that the validity period of the certificate meets the preset conditions, it is determined for the IoT device that the certificate is about to expire or has expired.

[0111] Combined with Figure 9 As shown, the embodiments of the present disclosure provide another method for data transmission, including:

[0112] S202, The router connects to the blockchain system.

[0113] S302, The IoT device connects to the blockchain system.

[0114] S310, The IoT device sends device information to the blockchain system.

[0116] S311, The IoT device obtains a certificate from the blockchain system.

[0117] S320, The IoT device encrypts the target data using the certificate issued by the blockchain system to obtain the request data.

[0122] S251, The router sends the target data to the corresponding network node.

[0123] S252, The router sends a data transmission request response to the IoT device.

[0124] Using the method for data transmission provided by the embodiments of the present disclosure, when the router receives a data transmission request from a device, it parses the request data in the data transmission request to determine the information in the request data. When it is determined that the request data carries a certificate issued by the blockchain system, it is determined that the device sending the data transmission request is an Internet of Things device, and the data needs to be sent preferentially. The request data is decrypted to obtain the target data that actually needs to be sent. The target data is placed in the priority sending queue to avoid interrupting the current data sending process and prevent preempting the sending priority of other Internet of Things devices. Since the target data of the Internet of Things device is placed in the priority sending queue, the sending priority of the target data is higher than that of non-Internet of Things devices, reducing the restriction of the router on the communication process of the Internet of Things device and thus reducing the possibility of the Internet of Things device dropping offline. Since the blockchain system and the certificate can encrypt the target data to prevent tampering, the security of data transmission is improved while reducing the offline of the Internet of Things device.
