Detailed ways

The technical solutions of the present application will be clearly and completely described in the following with reference to the specific embodiments of the present application and the corresponding drawings. It is apparent that the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without departing from the inventive scope are the scope of the application.

Based on the foregoing, the Internet of Things devices are generally Internet of Things smart items, and may include various smart items that can be carried around (such as smart bracelets, smart watches, etc.), various smart home items, and the like. In order to ensure the quality of IoT equipment and subsequent services, IoT devices usually carry unique corresponding identification information for identification. To prevent spoofing, the server usually needs to authenticate the IoT device that is trying to connect to it in advance.

In the embodiment of the present specification, the information interaction scheme for the Internet of Things device may adopt an architecture as shown in FIG. 1 , in which the server may include various clustered and distributed servers; Incoming points can include various access points (APs), such as routers, mobile hotspots, and the like. In practical applications, the interaction between the IoT device and the server, and the interaction between the client and the server can be implemented by the network access point. This interaction is preferably a data transparent transmission process for the network access point.

The information exchange process for the Internet of Things device provided by the embodiment of the present specification is described in detail below based on the architecture shown in FIG. 1. The process specifically includes the following three steps: client side, server side, and Internet of things device. In terms of aspects, they are explained separately. For the client side, including the following steps, as shown in FIG. 2, FIG. 2 is a schematic flowchart of the steps performed by the client in the information interaction scheme provided by the embodiment of the present disclosure:

Step S201: Acquire user information and identification information of the Internet of Things device.

The user information may generally include the user's account information, the user's device unique identification code, the user's identity card information, or the user's mobile phone number, and the like. The user information can be automatically obtained by the client from the local terminal or manually input to the client by the user.

The identification information of the IoT device is usually defined in advance by the service provider. In the actual application scenario, there may be multiple specific expressions, for example, a string formed by a combination of various characters, and the user can directly input to the client; or, Digital Object Unique Identifier (DOI), including various barcodes, two-dimensional codes; or a communication chip that can be recognized.

In practical applications, obtaining identification information of an IoT device may include the following various implementation manners, and two of them are listed:

The first type uses a terminal (for example, a camera such as a camera or a tag reader on the terminal) to scan the IoT device to obtain identification information of the IoT device. For example, when the IoT device carries a DOI, a Radio Frequency Identification (RFID), or a Near Field Communication (NFC) chip, it can be acquired by scanning the corresponding module of the terminal.

The second type is to receive the identifier information of the IoT device input by the user on the client. For example, when the identifier information of the IoT device is a string formed by various character combinations, the input method may be used by the user to input the string. Manually enter to the client.

Step S203: Send the user information and the identifier information of the Internet of Things device to the server for the server to authenticate.

The server can generate the authentication information according to the identification information of the IoT device and the user information by using a preset algorithm. For example, an algorithm generates a unique hash value according to the identification information of the Internet of Things device and the user information, and uses the hash value as the authentication information; for example, generates a security certificate according to the identification information of the Internet of Things device and the user information as the authentication. Information; and so on. The authentication information is then sent to the client so that the client can pass the authentication information to the IoT device.

The server can subsequently verify whether the IoT device attempting to connect is legitimate based on the authentication information.

Step S205, receiving authentication information returned by the server.

Step S207: Generate and send a data packet carrying the authentication information, so that the IoT device acquires the authentication information from the data packet for connecting to the server.

The data packet may include: a User Datagram Protocol (UDP) data packet, a Transmission Control Protocol (TCP) data packet, or a data packet in a custom format.

A packet usually includes a header and a data body. Taking a UDP packet as an example, the header includes fields such as a source IP address, a destination IP address, a packet length, and a checksum. The IoT device that has not been configured may not be able to parse the data body content of the UDP packet, but can parse the header content of the UDP packet relatively quickly. Based on this, the authentication information can be written into the header of the UDP packet to ensure the object. Networked devices can quickly obtain authentication information by quickly parsing them.

For example, in the target IP field of a UDP packet, the IP address of the receiver should be written under normal circumstances to achieve point-to-point transmission. However, in this embodiment, the IP address of the receiver is not written, but the authentication information is written into the target IP address field of the data packet, so that the IoT device receives and parses the content of the target IP address field to obtain the authentication information. .

For custom format packets, the protocol supporting the custom format can also be pre-written into the protocol stack of the IoT device to support the custom format packet parsing process. In this application scenario, the client writes authentication information to the header and/or data body of the packet as needed.

In practical applications, the amount of information that a single packet can carry is limited. When the authentication information to be transmitted is long, the authentication information may be split and written into a specified field (for example, a length or a target IP address) of the data packet to generate a plurality of data packets carrying partial authentication information.

Further, the client can broadcast the generated data packet on one or more channels in the connected wireless network. During the packet broadcast process, the IoT device that probes these channels can receive the packet.

In a specific implementation, before generating the data packet carrying the authentication information, performing: acquiring target network information. Further, in step S207, generating a data packet carrying the authentication information includes: generating a data packet carrying the authentication information and target network information.

The target network refers to a network on which an IoT device is connected when connecting to a server. The target network can be specified by the user through the client, or can be determined by the IoT device based on preset rules (for example, automatically scanning to an available passwordless WiFi network as the target network). The following embodiments are mainly explained based on the former method.

The target network is, for example, a wireless network to which the client is currently connected, or another wireless network designated by the user.

The target network information generally includes the identity of the target network and a password. For a WiFi network, the identity is specifically a Service Set Identifier (SSID), which is a so-called WiFi name. Of course, the target network may also have no password.

For example, the user terminal itself is connected to the network through the WiFi network M1, but a smart home appliance that is desired to be purchased is connected to the Internet through the WiFi network M5, and the password of the network M5 is 000000. In this scenario, the target network information includes the identity identifier M5 of the target network and its password 000000.

If the password is not required to connect to the network M5, the target network information includes the target network identity M5.

The method for obtaining the target network information may include: obtaining the client locally, or pre-setting by the user, inputting to the client, and the like.

Through the above solution, the client can transmit the target network information and the authentication information to the Internet of Things device at one time, which simplifies the operation of the user.

In a specific implementation, for the step S207, the data packet carrying the authentication information is generated, and the following method may be used. As shown in FIG. 3, FIG. 3 is a schematic flowchart of a data packet generating method according to an embodiment of the present disclosure:

Step S301: Perform format conversion on the authentication information according to a format of a specified data packet field.

The packet fields have a preset format, for example, the length field in the UDP packet is a number between 0 and 255. However, for the authentication information, it is not necessarily all numbers themselves. Based on this, the authentication information needs to be converted into a format acceptable for the data packet specifying field, and the field can be written.

Specifically, each byte in the byte sequence corresponding to the authentication information may be converted into a format acceptable for the specified field by using a certain rule, and then the formatted authentication information is written into the length of the data packet. Or the destination IP address field.

For example, assume that the rule is an American Standard Code of Content Interchange (ASCII) table. If the authentication information is the string "K2," in order to write the authentication information into the length field of the UDP packet, it is first necessary to convert "K2" into a format-compliant number. By querying the ASCII table, the byte corresponding to the character "K" contained in "K2" is 010011011 (binary), and the decimal value is 75, then 75 is the number obtained by "K" conversion; similarly, in "K2" The byte corresponding to the included character "2" is 00000010, and is represented by decimal data as 2, and 2 is the number obtained by the conversion of the character "2"; therefore, "K2" is converted into the numeric string 752.

Step S303: The data packet carrying the authentication information is obtained by writing the formatted authentication information into the corresponding data packet field; wherein, the designated data packet field includes: a data packet length field and/or a target IP address field.

Continuing the previous example, if the specified position is the length position, 75 can be written to the length position of a certain packet, and 2 is written to the length position of the next data packet. And issued in turn.

If the specified location is the destination IP address, the general format of the destination IP address is abcd, where a, b, c, and d are numbers between 0 and 255 (for example, 192.168.0.11). In actual applications, The processing method is as follows: the digital number is written to a specified position in the target IP address, for example, the number is written to the last bit of the target IP address.

The client side is described above. Based on the same idea, the information exchange process of the IoT device provided by the embodiment of the present specification is as shown in FIG. 4 for the server side, and FIG. 4 is provided by the embodiment of the present specification. A schematic flow diagram of the steps performed by the server in the information interaction scheme, including the following steps:

Step S401, receiving user information sent by the client and identification information of the Internet of Things device;

Step S403, performing authentication on the user information and/or the identifier information of the Internet of Things device, obtaining the authentication information, and returning to the client.

In an actual application scenario, the server may further perform: establishing and storing a binding relationship between the identifier information of the IoT device and the user information. For example, a one-to-one correspondence between the identification information of the IoT device and the user information is established in the form of a key-value pair, and the binding record is generated and stored locally to the server.

Further, the related Internet of Things service can be executed based on the stored binding relationship.

For example, when an IoT device is working in normal networking, it can collect signals through the sensors it carries and upload it to the server. The server performs signal analysis and binds the user information according to the signal analysis result and the stored binding relationship. The corresponding client makes feedback. Assuming that the IoT device is a smart bracelet, the server receives the pulse signal collected and sent by the smart bracelet for analysis, and sends the pulse signal analysis result to the bound user mobile phone number, so that the user can know the wearing of the smart bracelet at any time. The health status of the personnel.

As a specific implementation manner, after the obtaining the authentication information and returning to the client, performing: receiving the authentication information sent by the Internet of Things device; and based on the authentication information, A networked device establishes a trusted network connection.

Specifically, the server verifies the authentication information sent by the Internet of Things device, and after the verification is passed, establishes a trusted network connection with the Internet of Things device. For example, if the authentication information is stored in the server after being generated, after the authentication information sent by the IoT device is received, the authentication is completed by matching the received authentication information with the locally stored authentication information. For another example, if the authentication information is not saved on the server, the authentication information may be verified according to a preset algorithm (for example, a hash algorithm, etc.).

In practical applications, verifying authentication information may be one of the prerequisites for establishing a trusted network connection. In addition, other information processing actions may be required to establish a trusted network connection. These actions may require additional information from the IoT device and/or client.

The other information is, for example, identification information, location information, and the like of the Internet of Things device. By identifying the identification information of the IoT device, the server can simultaneously identify what the IoT device is in the verification process, and obtain the user information corresponding to the IoT device according to the binding relationship; similarly, obtain the location of the IoT device. Information, the server can understand where the IoT device is and perform business based on location.

The server side is described above. Based on the same idea, the IoT item information interaction method provided by the embodiment of the present specification is as shown in FIG. 5 for the server side, and FIG. 5 is provided for the embodiment of the present specification. A schematic diagram of the flow of steps performed by the IoT device in the information interaction scheme, including the following steps:

Step S501: Acquire a data packet that carries the authentication information sent by the client, and acquire the target network information.

Specifically, the following embodiments may be adopted: monitoring multiple radio network signal broadcast channels; and acquiring the data packets carrying the authentication information sent by the client.

For example, an IoT device first acquires a plurality of surrounding wireless network signal broadcast channels, and then performs polling (if there is only one, no polling is required), and listens to data packets in each channel to determine the wireless network signal broadcast channel. When the data packet satisfies the preset condition, the data packet is acquired in the current wireless network signal broadcast channel. For example, it is monitored whether the received packet header contains a preset tag, and if so, it is determined as the packet carrying the authentication information, and the packet is acquired. There are a variety of specific determination conditions, which are not listed here.

For the acquisition target network information, in an actual application scenario, as an implementable manner, the Internet of Things device can obtain the target network from the WiFi network of the surrounding environment. For example, the Internet of Things device polls the WiFi network of the surrounding environment, and finds that a certain public WiFi network can be networked without a password. At this time, the public WiFi network is the target network.

As another implementation manner, the target network information may be obtained by acquiring a data packet that is sent by the client and carries the authentication information and the target network information.

For example, the user connects to the network through the home network WiFi, and specifies that the Internet of Things device is also connected from the home network WiFi, and the client obtains the WiFi information of the home network as the target network information and writes the data packet for broadcast. At this time, the IoT device can acquire the target network information (ie, the WiFi information of the home network) from the received data packet.

Step S503, performing network configuration according to the target network information to access the target network.

Step S505, establishing a trusted network connection with the server according to the authentication information and the target network that has been accessed.

That is, in the connected target network, the authentication information is sent to the server, and after the server verifies that the authentication information is legal, the two parties establish a trusted network connection.

As a specific implementation manner, before performing the network configuration according to the target network information, the method further includes: performing format conversion on the specified field of the data packet, and acquiring the authentication, according to a preset rule. information.

For example, the length field of the received data packet is sequentially queried, the numbers 75 and 2 are obtained, converted according to the ASCII table, and spliced in order to obtain the authentication information as "K2".

The various embodiments in the specification are described in a progressive manner, and the same or similar parts between the various embodiments may be referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the device, the device, and the media type embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method embodiment, which will not be repeated here.

The foregoing description of the specific embodiments of the specification has been described. Other embodiments are within the scope of the following claims. In some cases, the acts or steps or modules recited in the claims can be performed in a different order than in the embodiments and the desired results can still be achieved. In addition, the processes depicted in the figures are not necessarily in a particular order or in a sequential order to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

In the 1990s, improvements to a technology could clearly distinguish between hardware improvements (eg, improvements to circuit structures such as diodes, transistors, switches, etc.) or software improvements (for process flow improvements). However, as technology advances, many of today's method flow improvements can be seen as direct improvements in hardware circuit architecture. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be implemented by hardware entity modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is an integrated circuit whose logic function is determined by the user programming the device. Designers can program themselves to "integrate" a digital system on a single PLD without having to ask the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, today, instead of manually making integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in programming development, but before compiling The original code has to be written in a specific programming language. This is called the Hardware Description Language (HDL). HDL is not the only one, but there are many kinds, such as ABEL (Advanced Boolean Expression Language). AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., are currently the most commonly used VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be apparent to those skilled in the art that the hardware flow for implementing the logic method flow can be easily obtained by simply programming the method flow into the integrated circuit with a few hardware description languages.

The controller can be implemented in any suitable manner, for example, the controller can take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (eg, software or firmware) executable by the (micro)processor. In the form of logic gates, switches, application specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers, examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, The Microchip PIC18F26K20 and the Silicone Labs C8051F320, the memory controller can also be implemented as part of the memory's control logic. Those skilled in the art will also appreciate that in addition to implementing the controller in purely computer readable program code, the controller can be logically programmed by means of logic gates, switches, ASICs, programmable logic controllers, and embedding. The form of a microcontroller or the like to achieve the same function. Such a controller can therefore be considered a hardware component, and the means for implementing various functions included therein can also be considered as a structure within the hardware component. Or even a device for implementing various functions can be considered as a software module that can be both a method of implementation and a structure within a hardware component.

The system, device, module or unit illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product having a certain function. A typical implementation device is a computer.
