Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise, and "a plurality" typically includes at least two.

The words "if", as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.

In addition, the sequence of steps in each method embodiment described below is only an example and is not strictly limited.

Before specifically describing the device connection scheme provided by the embodiments of the present invention, several concepts involved herein will be described.

The servers herein may be independent physical hosts or clusters of hosts located in the cloud.

The wireless hotspot device in this context is a device that can be a wifi hotspot, such as an internet of things device such as a sound box and a robot.

The target device in this document refers to a device to establish a communication connection with the wireless hotspot device, and may be, for example, a mobile phone, a computer, a sound box, a robot, or the like.

A device to be networked in this context may be a terminal device, such as a refrigerator, a loudspeaker, a robot, etc., which is not yet connected to some wireless network to which it is desired to access, and is therefore referred to as a device to be networked.

The distribution network device can be a mobile phone, a tablet computer and other terminal devices, and the distribution network device can already access a certain wireless network through a router and other network devices, for example, a mobile phone of a user already accesses a wifi network of a home through a wireless router installed in the home.

It should be noted that the distribution network device may also be a terminal device that does not have a human-computer interaction screen, such as a refrigerator or a sound box that has already accessed a wireless network, and at this time, the distribution network device may locally store network configuration information of a router that is accessed by the distribution network device, so as to perform network configuration on a device to be networked that does not access the network.

In addition, a distribution network application program can run in the distribution network equipment, and network configuration of the equipment to be networked is realized through the distribution network application program.

In brief summary, a network distribution device and a device to be networked belong to the same user, and the two devices mainly differ from each other: the network distribution equipment has access to a certain wireless network, the equipment to be networked has not access to the wireless network, and the purpose of network configuration of the equipment to be networked is to enable the equipment to be networked to access to the wireless network.

The following describes an apparatus connection scheme and a network configuration scheme provided in the embodiments of the present invention.

Fig. 1 is a schematic work flow diagram of an apparatus connection system according to an embodiment of the present invention, and as shown in fig. 1, the apparatus connection system includes: the system comprises a wireless hotspot device and a target device to be connected with the wireless hotspot device. The device connection process may include the steps of:

101. the wireless hotspot device generates a first random number, generates a service set identifier according to the device identifier of the wireless hotspot device and the first random number, and generates an access key according to the first random number and a private key of the wireless hotspot device.

If the wireless hotspot device starts the wifi hotspot function, the SSID of the wireless hotspot device needs to be broadcasted to the outside, so that a target device which needs to be connected with the wireless hotspot device can discover the wireless hotspot device. Additionally, to ensure connection security, the wireless hotspot device may be configured with an access key. In this embodiment, a scheme for turning on a wireless hotspot device is provided, where the scheme specifically relates to generating an SSID and an access key of the wireless hotspot device.

Specifically, in the embodiment of the present invention, the key parameters required for generating the SSID and the access key of the wireless hotspot device are: the device identification and the private key of the wireless hotspot device and the random number (namely the first random number) generated by the wireless hotspot device.

The device identification and the private key of the wireless hotspot device are burnt in the wireless hotspot device in advance, and are stored in a cloud server in advance.

In practical application, when a user operates the wireless hotspot device to start the wifi hotspot function of the wireless hotspot device, the wireless hotspot device may be triggered to generate a first random number. The first random number may be a numeric value of a set number, such as hexadecimal, decimal, binary, or the like.

In practical application, it is not limited that all devices supporting the wifi hotspot function are executed according to the scheme provided by the embodiment of the present invention when the wifi hotspot function is started, and the scheme provided by the embodiment of the present invention may be executed only when certain wireless hotspot devices are started. At this time, the device identifications and the private keys of the specific wireless hotspot devices, such as certain brands, models, and kinds of internet of things devices, are stored in the cloud server. That is to say, code scripts are written in the specific wireless hotspot devices in advance, and when a user starts the wifi hotspot function of the wireless hotspot device, the code scripts are run to execute the device connection scheme provided by the embodiment of the invention.

In turn, the wireless hotspot device generates an SSID based on the generated first random number and the device identification. Alternatively, the wireless hotspot device may simply concatenate the device identification and the first random number to form the SSID. In practical applications, the device identifier and the first random number may each correspond to a set length, for example, the device identifier occupies 20 bytes in length, and the random number is 12 bytes in length. Certainly, in practical application, in consideration of readability of a user, certain format conversion may also be performed on the first random number, and a splicing result of the first random number after format conversion and the device identifier is used as an SSID.

In addition, the wireless hotspot device generates an access key based on the generated first random number and a private key of the wireless hotspot device. Optionally, the wireless hotspot device may compute the first random number and a private key of the wireless hotspot device using any one of encryption algorithms, such as MD5, SHA1, SHA224, SHA256, etc., to obtain the access key. It can be appreciated that the role of the wireless hotspot device in generating the access key is to: when the target device establishes a connection with the wireless hotspot device based on the discovery result of the SSID of the wireless hotspot device, the wireless hotspot device may determine whether to approve the connection request of the target device based on whether the access key input by the target device is consistent with the access key generated by the wireless hotspot device.

After the SSID and the access key are automatically generated according to the above process, the wireless hotspot device may construct a management frame including the SSID, and broadcast and transmit the management frame to the outside.

Generally, the communication protocols adopted by the target device and the wireless hotspot device are in accordance with the 802.11 standard, and in the 802.11 standard, many management frames are defined, so the management frames can be selected from any one of the management frames defined by the 802.11 standard.

Common management frames include: beacon (beacon) frame, probe request (probe request) frame. Therefore, the management frame generated by the device to be networked may be selected from any of the above.

Taking a beacon frame as an example (probe request frame and the like), a plurality of fields may be included in the beacon frame, wherein one field is a field for populating an SSID, and therefore, the wireless hotspot device may populate the generated SSID into the field to generate the beacon frame.

102. And the wireless hotspot device broadcasts and transmits a management frame comprising the generated service set identification.

In short, it is the wireless hotspot device that broadcasts its SSID outwards, that is, broadcasts its network name, and the management frame is only the bearer of the SSID. In practical applications, it may be set to broadcast every 100 milliseconds, for example.

103. And the target equipment determines that the wireless hotspot equipment is the wireless hotspot equipment needing to be connected according to the received management frame, and acquires the access key according to the equipment identifier and the first random number which are analyzed from the service set identifier.

104. And the target equipment is connected with the wireless hotspot equipment according to the access key.

In practical applications, for a target device, at a certain time, it may receive not only the management frame sent by the wireless hotspot device, but also management frames sent by other devices, such as a beacon frame sent by a router, where the management frames may all include the SSID of the corresponding device. At this time, the target device needs to distinguish which management frame corresponds to the wireless hotspot device to which the target device wants to connect, that is, the target device needs to be able to determine that the wireless hotspot device is a device that needs to be connected according to the received management frame sent by the wireless hotspot device.

Two optional implementation manners are provided below to implement the identification of the target device for the wireless hotspot device that needs to be connected, that is, the target device may determine whether the sending device corresponding to the received management frame is the wireless hotspot device that needs to be connected according to the following two optional implementation manners.

The first implementation mode comprises the following steps: a specific identifier may be set in a management frame generated by the wireless hotspot device. Therefore, if the target device analyzes the identifier from a certain received management frame, the target device determines that the device sending the management frame is the wireless hotspot device needing to be connected. For example, assuming that a user wants to connect to a smart speaker (as a wireless hotspot device) in a home with his/her handset (as a target device), assuming that the handset can search for an SSID including, in addition to an SSID _ a sent by the smart speaker, an SSID _ B sent by a router next to the home, however, since a management frame sent by the smart speaker includes, in addition to the SSID _ a, the specific identifier, such as an ABH, and the management frame sent by the router does not include the identifier, the handset determines that connection with the router is not needed and connection with the smart speaker is needed.

The second implementation mode comprises the following steps: the target device analyzes the SSID contained in the received management frame to analyze the device identifier contained in the SSID, and further queries the server by using the device identifier, if the server includes the device identifier, it is indicated that the management frame is sent by a certain wireless hotspot device registered in the server in advance, and it can be determined that the management frame needs to be connected with the wireless hotspot device. Specifically, since the lengths of the device identifier and the first random number that constitute the SSID of the wireless hotspot device can be specified in practical applications, the target device can parse the corresponding device identifier from the received SSID according to the length setting. Of course, it is understood that, for example, if a certain management frame received by the target device is sent by a device such as a router that does not need to be connected, part of the field information extracted from the SSID of the management frame according to the above-mentioned length setting condition will not exist in the server.

When the target device determines that a received management frame is sent by the wireless hotspot device needing to be connected, the access key required by the connection of the wireless hotspot device can be obtained according to the device identifier of the wireless hotspot device and the first random number, which are obtained by analyzing the management frame.

Optionally, the target device may send a first key obtaining request to the server, where the first key obtaining request includes a device identifier and a first random number that are parsed from the SSID. After receiving the first key acquisition request, the server queries a private key of the wireless hotspot device corresponding to the device identifier according to the device identifier, and generates an access key according to the first random number and the private key. The target device receives the access key fed back by the server, and further, the target device may send a connection request to the wireless hotspot device, where the connection request includes the access key. And after receiving the connection request, the wireless hotspot device compares the access key contained in the connection request with an access key generated by the wireless hotspot device according to the private key and the first random number, and if the access key is consistent with the private key and the first random number, the wireless hotspot device establishes communication connection with the target device. It is understood that the encryption algorithm used by the server to generate the access key corresponds to the encryption algorithm used by the wireless hotspot device.

In summary, according to the above scheme, the target device may automatically discover the wireless hotspot device that needs to be connected, and further automatically acquire the access key accessed to the wireless hotspot device, so as to implement automatic connection with the wireless hotspot device.

It is to be appreciated that the purpose of the target device establishing a connection with the wireless hotspot device is to communicate data information with the wireless hotspot device. In different application scenarios, the transmitted data information may be different. For example, in a scenario where the target device performs network configuration for the wireless hotspot device, the transmitted data information will be network configuration information of a certain router that the wireless hotspot device is expected to access. For another example, in a scenario where the target device controls the wireless hotspot device to operate, the transmitted data information will be some control commands, such as a switch command, a parameter adjustment command, and the like.

In the following, a solution is provided for ensuring the security of data information transmission, regardless of the type of data information to be transmitted, as outlined in connection with the embodiment shown in fig. 2.

Fig. 2 is another schematic workflow diagram of the device connection system according to the embodiment of the present invention, as shown in fig. 2, the device connection system may include a wireless hotspot device, a target device, and a server, and the working process may specifically include the following steps:

201. the wireless hotspot device generates a first random number, an SSID is generated according to the device identification of the wireless hotspot device and the first random number, and an access key is generated according to the first random number and a private key of the wireless hotspot device.

202. And the wireless hotspot device broadcasts and transmits a management frame comprising the generated SSID.

203. And the target device determines that the wireless hotspot device is the wireless hotspot device needing to be connected according to the received management frame.

204. The target device sends a first key acquisition request to the server, wherein the first key acquisition request comprises a device identifier and a first random number which are analyzed from the SSID.

205. The server obtains a private key of the wireless hotspot device according to the device identification, and generates an access key according to the first random number and the private key.

206. The server sends the access key to the target device.

207. And the target equipment is connected with the wireless hotspot equipment according to the access key.

208. The target device generates a second random number.

209. And the target equipment sends a second key acquisition request to the server, wherein the second key acquisition request comprises the equipment identification of the wireless hotspot equipment and a second random number.

210. And the server generates an encryption key according to the second random number and the private key of the wireless hotspot device.

211. The server sends the encryption key to the target device.

212. And the target equipment encrypts the data information which needs to be transmitted to the wireless hotspot equipment according to the encryption key.

213. And the target equipment sends the encrypted data information and the second random number to the wireless hotspot equipment.

214. And the wireless hotspot equipment generates a decryption key according to the second random number and the private key of the wireless hotspot equipment, and decrypts the encrypted data information according to the decryption key.

In this embodiment, the execution process of steps 201-207 may refer to the description in the foregoing other embodiments, which is not described herein again.

In this embodiment, in order to ensure the transmission security of the data information, the data information may be encrypted for transmission. Two key parameters for generating the encryption key are: a private key of the wireless hotspot device and a second random number generated by the target device. Similarly, two key parameters for generating the decryption key corresponding to the encryption key are also: a private key of the wireless hotspot device and a second random number generated by the target device.

Wherein optionally the encryption key is generated by the server. The decryption key is generated by the wireless hotspot device.

Specifically, after the target device is connected to the wireless hotspot device, a second random number with a set length may be generated, and further, a second key acquisition request including the device identifier and the second random number may be sent to the server based on the device identifier analyzed from the management frame sent by the wireless hotspot device. After receiving the second key acquisition request, the server queries a private key of the wireless hotspot device corresponding to the second key acquisition request based on the device identifier contained in the second key acquisition request, and then performs encryption calculation on the private key and the second random number by adopting a certain encryption algorithm to obtain an encryption key. In practical applications, the encryption algorithm used by the server to generate the encryption key may be different from the encryption algorithm used to generate the access key in the foregoing, so as to enhance security.

After receiving the encryption key fed back by the server, the target device encrypts the data information to be sent to the wireless hotspot device, and further, the encrypted data information and the second random number of the plaintext can be sent to the wireless hotspot device through the communication connection established with the wireless hotspot device.

And the wireless hotspot device generates a decryption key based on the received second random number and a locally stored private key so as to decrypt and obtain the data information sent by the target device. The algorithm used for decryption key generation corresponds to the algorithm used for encryption key generation.

In addition, to further improve the security, the target device may set a lifetime of the second random number when generating the second random number, so that the encryption key and the decryption key generated based on the second random number also have a certain lifetime. If the life time exceeds the life time, the encryption key and the decryption key are invalid, and at the moment, if the subsequent target equipment still needs to transmit data information with the wireless hotspot equipment, a new second random number needs to be generated again.

In summary, based on the scheme provided in this embodiment, not only can the automatic connection between the target device and the wireless hotspot device be realized, but also the security of data transmission between the target device and the wireless hotspot device can be ensured.

The following takes a distribution network scenario as an example, and an actual application process of the device connection method provided above in the distribution network scenario is exemplarily described. At this time, the foregoing wireless hotspot device is a device that needs to perform network configuration, and is called a device to be networked; the target device is a device for network configuration of the wireless hotspot device, and is called a distribution network device.

Fig. 3 is a schematic flow chart of a network configuration process according to an embodiment of the present invention, and as shown in fig. 3, the network configuration process may include the following steps:

301. the device to be accessed to the network generates a random number, an SSID is generated according to the device identification of the device to be accessed to the network and the random number, and an access key is generated according to the random number and the private key of the device to be accessed to the network.

302. And the equipment to be accessed to the network broadcasts and sends a management frame comprising the SSID.

303. The distribution network equipment determines that the equipment to be accessed to the network, which sends the management frame, is the equipment needing to be connected according to the received management frame, and acquires an access key according to the equipment identifier and the random number which are analyzed from the SSID of the management frame.

304. The network distribution equipment is connected with the equipment to be networked through the access key.

305. And the distribution network equipment sends the network configuration information of the router to the equipment to be networked.

306. And the equipment to be networked is connected with the router according to the network configuration information.

In this embodiment, a hotspot mode (also referred to as an AP mode or a softAP mode) is used to perform network configuration on a device to be networked. In the hotspot mode, the device to be networked needs to start a wifi hotspot function, and externally broadcasts an SSID of the device to enable the distribution network device to discover the device to be networked, and then is connected to the device to be networked through an access key corresponding to the device to be networked, and then the distribution network device sends network configuration information of a router which is expected to be connected to the device to be networked based on communication connection between the distribution network device and the device to be networked. The network configuration information includes an SSID, an access PASSWORD (PASSWORD), a Basic Service Set Identifier (BSSID), and the like corresponding to the router.

For the specific implementation process of the above steps, reference may be made to the related descriptions in the foregoing other embodiments, which are not described herein again. It is understood that the process of the distribution network device obtaining the access key and the encryption key may be obtained by the request server, and the specific process refers to the relevant description in the foregoing embodiments.

To more intuitively understand the process of performing network configuration on the device to be networked by using the hotspot mode, the description is given with reference to fig. 4.

In fig. 4, it is assumed that the device to be networked is a sound box and the network distribution device is a mobile phone. Assuming that the mobile phone is currently connected to a router, the SSID corresponding to the router is represented as: SSID _ a, which is the network name of the wireless network corresponding to the router. Suppose that the SSID generated by the speaker based on the self-generated random number and the device identifier is expressed as: and SSID _ B, namely the network name of the wireless network corresponding to the hot spot where the sound box is started.

The purpose of network configuration of the speaker by the mobile phone is to expect that the speaker can be connected to the router to which the mobile phone is currently connected.

As can be seen from fig. 4, to achieve this, initially, the handset is connected to the router, i.e. the handset accesses the wireless network with the network name SSID _ a.

And then, when the user starts the wifi hotspot function of the sound box, the sound box creates a wireless network with the name of SSID _ B, generates an access KEY KEY and further broadcasts the SSID _ B to the outside. Wherein, SSID _ B includes device identification Dev and random number Rand of the loudspeaker box. The access KEY is generated from the private KEY of the loudspeaker and the random number Rand.

After the mobile phone senses the SSID _ B, the device identification Dev and the random number Rand are analyzed from the SSID _ B, the server is requested to obtain an access KEY KEY of the sound box based on the device identification Dev and the random number Rand, the access KEY KEY is automatically connected to the sound box, the connection with the router is disconnected, and the mobile phone is switched to a wireless network with an access network name of SSID _ B. The device identification Dev of the server queries the private KEY of the sound box, and then generates an access KEY according to the private KEY and the random number Rand.

Based on the connection with the sound box, the mobile phone further issues the network configuration information of the router connected so far to the sound box, which is equivalent to that the mobile phone informs the sound box of the network configuration information required by the wireless network with the access network name SSID _ a, such as the network name SSID _ a and the access key paswd of the router.

The sound box is accessed to the wireless network SSID _ A based on the received network configuration information, namely is connected with the router. And then, the mobile phone switches back to the wireless network SSID _ A.

In conclusion, when the network configuration is performed on the device to be networked in the hotspot mode, the automatic connection between the network distribution device and the device to be networked can be realized through the scheme, manual intervention is not required, and the efficiency of network configuration is improved.
