Description

Method and device for accessing network to be configured to network hotspot equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for accessing a device to be networked to a network hotspot device and a device for accessing the device to be networked to the network hotspot device.

background

Along with the development of the internet of things, in the intelligent family scene of the internet of things, more and more intelligent devices use WiFi to access the family router to realize the functions of remote device control, scene linkage and the like.

before the intelligent device accesses the internet lnt, the SSID (Service Set Identifier) and the Password of the router need to be obtained by means of a distribution network scheme. The current distribution network scheme mainly comprises two schemes, one is a WiFi broadcast distribution network scheme, and the other is a WiFi multicast distribution network.

The WiFi broadcast distribution network adopts a Length field to transmit the SSID and the Password of the router, and the WiFi multicast distribution network adopts a Destination field to transmit the SSID and the Password of the router. The existing WiFi broadcast/multicast one-key distribution network firstly encodes the SSID and the Passsword of the router, and then the codes are sequentially sent to equipment to be distributed by a mobile phone. Wherein the loss of any one byte in these encodings will not resolve the SSID and Password of the router correctly. Since the probability of each byte being lost is approximately the same, theoretically, the longer the length of SSID and Password is, the lower the probability of error is, and the lower the probability of correctly resolving SSID and Password of the router is.

Detailed Description

in order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

referring to fig. 1, a flowchart illustrating a first step of a first method embodiment of accessing a device to be networked to a network hotspot device in the present application is shown, which may specifically include the following steps:

Step 101, a device to be configured acquires password information of a target network hotspot device and a target Basic Service Set Identifier (BSSID) sent by a user terminal;

in this embodiment, the network hotspot device may be a router, or may be a wireless access point ap (access point) without a routing function.

In the scene of the Internet of things, network hotspot equipment is arranged to provide WIFI hotspots for the intelligent equipment. The device to be networked is a device which needs to access a WIFI hotspot, such as an intelligent household appliance and a camera in a household, and various sensors and detectors in a factory.

In general, a device to be configured needs to access a network hotspot device by using password information and SSID (Service Set Identifier) of the network hotspot device. In the embodiment of the application, the user terminal sends the password information and the BSSID of the target network hotspot device to the device to be networked, but does not send the SSID.

The Password information is a Password (Password) of a WIFI hotspot of the router, BSSID (Basic Service Set Identifier) is an Identifier of a BSS (Basic Service Set), and the Basic Service Set is used for describing a group of devices which communicate with each other.

in the embodiment of the present application, the user terminal may support wireless communication devices of 802.11 and 802.2 communication protocols, such as a mobile phone, a tablet computer, a personal digital assistant, and the like. A distribution network application program APP can be installed in the user terminal, and the password information and the target BSSID of the target network hotspot device are sent to the device to be distributed through the distribution network APP.

step 102, the device to be networked searches a target SSID corresponding to the target BSSID from BSSIDs and service set identifiers SSIDs of a plurality of preset network hotspot devices;

in the embodiment of the application, BSSIDs and SSIDs of a plurality of network hotspot devices are preset in the device to be networked.

specifically, the device to be networked maintains a hotspot list, and BSSIDs and SSIDs of a plurality of network hotspot devices are recorded in the list. The BSSID of each network hotspot device corresponds to the SSID one to one, that is, a unique corresponding SSID can be found according to the BSSID. And the network-to-be-distributed equipment searches a target SSID corresponding to the target SSID from the hotspot list, wherein the target SSID is the SSID of the target network hotspot equipment.

the BSSID and SSID of the network hotspot device in the hotspot list may be input into the device to be networked by the user, or may be extracted from a Beacon packet sent by the network hotspot device by the device to be networked. Generally, a network hotspot device sends a Beacon packet to a device to be networked according to a certain time interval, where the Beacon packet includes a BSSID and an SSID of the network hotspot device.

and 103, the equipment to be networked accesses the target network hotspot equipment by adopting the password information and the target SSID.

the network to be distributed can access the hot spot of the target network hotspot device by adopting the password information and SSID of the target network hotspot device.

Referring to fig. 2, a flowchart illustrating steps of a second embodiment of a method for accessing a device to be networked to a network hotspot device according to the present application is shown, where the method specifically includes the following steps:

step 201, a device to be configured receives a User Datagram Protocol (UDP) packet sent by a user terminal;

in this embodiment, the user terminal may send a user Datagram protocol udp (user Datagram protocol) packet to the device to be networked according to an 802.11 protocol or an 802.2 protocol. The header of each UDP packet contains the BSSID and is disclosed in plain text. The user terminal may encode the password information into a specific field of the UDP packet.

specifically, the UDP sent by the user terminal may include a network distribution packet, and the user terminal may encode the password information into a plurality of network distribution packets; the step 201 may include: and the equipment to be configured receives a plurality of network configuration packets sent by the user terminal.

In the embodiment of the application, the amount of information that can be encoded by each distribution network packet is limited, and each distribution network packet can only encode a part of password information, so that the user terminal can encode the password information into a plurality of distribution network packets. The network equipment to be distributed needs to analyze the password information from a plurality of network distribution packets.

in this embodiment of the present application, the UDP sent by the user terminal may further include a synchronization packet; the step 201 may further include: and the equipment to be distributed receives at least one synchronous packet sent by the user terminal before receiving the plurality of network distribution packets sent by the user terminal.

Specifically, the user terminal may send at least one synchronization packet before sending each of the distribution network packets. After the device to be connected to the network receives the synchronization packet, it can know that the device to be connected to the network receives the distribution packet later.

step 202, the device to be networked acquires the password information of the target network hotspot device and the target basic service set identifier BSSID from the UDP packet.

The equipment to be distributed performs empty packet grabbing, the BSSID in the packet header can be obtained in the grabbed UDP packet, and the equipment to be distributed can obtain the target BSSID from the synchronous packet and can also obtain the BSSID from the network distribution packet because each UDP packet contains the BSSID.

And the equipment to be networked analyzes the password information from the plurality of captured UDP packets. Specifically, the device to be networked can analyze the password information from a plurality of networking packets. In this embodiment of the application, the device to be configured may obtain the password information of the target network hotspot device from the plurality of network distribution packets. The method specifically comprises the following substeps:

Substep S11, the device to be networked acquires coding information from the multiple networking packages; the encoding information includes: encryption mode information, password length information, encrypted password information;

Referring to fig. 3, a schematic diagram of encoded information in the embodiment of the present application is shown. The encoding information may be composed of encryption mode information, password length information, encrypted password information, and check code information in sequence. The arrangement sequence of various information in the coding information can be agreed in advance between the user terminal and the equipment to be networked, and after the equipment to be networked analyzes the complete coding information, the various information can be determined according to the agreed sequence.

in the embodiment of the application, in order to increase the confidentiality of the password information, the password information can be encrypted. The encryption mode information indicates which encryption mode is used for encrypting the cipher information, such as AES128-CFB encryption mode and AES128-OFB encryption mode. The encrypted password information can be decrypted by adopting a corresponding decryption mode according to the encrypted information. Specifically, the encryption mode information may be only one numerical value, each numerical value is agreed to correspond to one encryption mode, and which numerical value corresponds to which encryption mode is agreed in advance between the user terminal and the distribution network device.

the cipher length information indicates the length of the encrypted cipher information. In the encoded information, the length of the encryption mode information is fixed (e.g. 1Byte), the length of the password length information is fixed (e.g. 1Byte), the length of the check code information is also fixed (e.g. 1Byte), and the length of the encrypted password information is not fixed (may be n Byte). The equipment to be distributed needs to obtain encrypted password information with corresponding length from the coding information according to the password length information.

The equipment to be distributed can adopt the check code information to carry out check; and if the verification is wrong, the equipment to be distributed discards the coding information analyzed from the multiple network distribution packets.

In an example of the embodiment of the present application, the sub-step S11 may further include:

Step S111, the network equipment to be distributed analyzes the Length fields Length of the received multiple network distribution packets;

And a substep S112, determining coding information by the equipment to be distributed according to the length fields of the plurality of network distribution packets.

Each network distribution package has a Length field Length, the value of the Length field corresponding to the Length of the Data part Data in the network distribution package. After the network distribution equipment receives the network distribution packet, the content of the data part of the network distribution packet is not concerned, and only the length of the data part is concerned.

the length field of each distribution network packet can represent a code value, and the code information is actually formed by combining a plurality of code values.

In this example, the encoded information may include a plurality of bytes, and the byte length of the encoded value of each distribution network packet is limited, so that a plurality of distribution network packets need to be transmitted to completely transmit the encoded information.

the user terminal can divide the distribution network packet into a plurality of groups, after the equipment to be distributed receives the groups of the distribution network packet, the coding values of the distribution network packet are arranged in the groups according to the specified sequence, and the coding values of the groups are arranged among the groups according to the sequence of the groups.

fig. 4 is a schematic diagram illustrating sending of coded information in the embodiment of the present application. The user terminal sends at least one synchronization packet before sending each group of networking packets. The length of each synchronization packet reflects the order of the corresponding packet. After the user terminal sends a group of distribution network packets, the user terminal sends a synchronization packet corresponding to the next group of distribution network packets, and then sends the next group of distribution network packets. After the user terminal sends all the grouped distribution network packets, the user terminal can repeatedly send all the grouped distribution network packets.

The order of the distribution packets in the packet may also be determined according to the length of the data portion of each distribution packet. Specifically, the length field of each networking packet is obtained by adding an intra-group offset, which determines the order of the encoded values within the group, to the encoded value. It is agreed in advance between the network equipment to be configured and the user terminal which bits (bit) in the length field are offset and which bits are coding value. Therefore, the equipment to be distributed can determine the arrangement sequence of the code values in the group and the code values from the length field.

In order to make those skilled in the art better understand the transmission method of the encoded information in the embodiment of the present application, the following description is made by way of an example:

the user terminal may encode the encoded information using three bytes at the end of the destination MAC address.

the destination MAC address of each distribution packet may represent a coded value, and the coded information is actually a combination of a plurality of coded values.

the user terminal transmits at least one synchronization packet before each set of networking packets. The length of each synchronization packet reflects the order of the corresponding packet.

The order of the network packets in the packet may also be determined based on the destination MAC address of each network packet.
