Background

Many terminal devices have a wireless Access Point (AP) function, which is simply to convert a network signal received by the terminal device, such as GPRS, 3G, or 4G, into a wifi signal and send the wifi signal.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the 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.

Similarly, the phrase "if determined" or "if detected (stated condition or event)" may be interpreted as "when determined" or "in response to determination" or "when detected (stated condition or event)" or "in response to detection (stated condition or event), depending on the context.

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

Before describing the device connection scheme provided by the embodiment of the present invention in detail, several concepts related to the present invention will be described.

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

The wireless hotspot device in the present disclosure may be a device that may be used as a wifi hotspot, for example, may be a speaker, a robot, or an internet of things device.

The target device herein refers to a device that is to establish a communication connection with the wireless hotspot device, for example, a mobile phone, a computer, a sound box, a robot, and the like.

The network-to-be-connected device in this context may be a terminal device such as a refrigerator, a loudspeaker, a robot, etc., which has not yet been connected to a certain wireless network to which access is desired, and is thus referred to as a network-to-be-connected device.

It should be noted that, the network configuration device may also be a terminal device that has been connected to a wireless network and does not have a man-machine interaction screen, such as a refrigerator or a sound box, where the network configuration device may locally store network configuration information of an accessed router, so as to perform network configuration on a device to be connected to the wireless network.

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

In brief summary, the distribution network device and the device to be connected to the network are two devices belonging to the same user, and the two devices are mainly different from each other: the network configuration of the network equipment to be accessed is that the network equipment to be accessed is accessed to the wireless network.

The device connection scheme and the network configuration scheme provided by the embodiment of the invention are explained below.

Fig. 1 is a schematic workflow diagram of a device connection system according to an embodiment of the present invention, where, as shown in fig. 1, the device connection system includes: wireless hot spot equipment and target equipment to be connected with the wireless hot spot equipment. The device connection process may include the steps of:

101. The wireless hot spot equipment generates a first random number, generates a service set identifier according to the equipment identifier of the wireless hot spot equipment and the first random number, and generates an access key according to the first random number and a private key of the wireless hot spot equipment.

If the wireless hotspot device starts the wifi hotspot function, the wireless hotspot device needs to broadcast its SSID to the outside so that the target device connected with the wireless hotspot device can find the wireless hotspot device. In addition, to ensure connection security, the wireless hotspot device may be configured with an access key. In this embodiment, a scheme for starting up 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, key parameters required for generating the SSID and the access key of the wireless hotspot device are: the device identifier, the private key of the wireless hotspot device and the random number generated by the wireless hotspot device (i.e. the first random number) are set as the above.

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

In practical applications, when a user operates a wireless hotspot device to start a 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 set-up value, such as hexadecimal, decimal, binary, etc.

In practical application, the implementation of the scheme provided by the embodiment of the invention is not limited by all the devices supporting the wifi hotspot function when the wifi hotspot function is started, and the scheme provided by the embodiment of the invention can be configured to be implemented only by specific wireless hotspot devices when the wifi hotspot function is started. At this time, the device identifiers and private keys of the specific wireless hotspot devices are stored in the cloud server, where the specific wireless hotspot devices are, for example, internet of things devices with certain brands, models and types. That is, a code script is written in advance in the specific wireless hotspot devices, and when a user opens a wifi hotspot function of the wireless hotspot device, the code script is run to execute the device connection scheme provided by the embodiment of the present invention.

Further, 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 nonce 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. Of course, in practical application, in consideration of the readability of the user, a certain format conversion may be performed on the first random number, and the spliced result of the first random number after the format conversion and the device identifier is used as the SSID.

In addition, the wireless hotspot device generates an access key based on the generated first random number and the private key of the wireless hotspot device. Alternatively, the wireless hotspot device may calculate the first random number and the private key of the wireless hotspot device using any one of the encryption algorithms, such as MD5, SHA1, SHA224, SHA256, etc., to obtain the access key. It will be appreciated that the role of the wireless hotspot device to generate 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 agree with the connection request of the target device based on whether the access key input by the target device coincides with the access key generated by itself.

After automatically generating the SSID and the access key according to the above procedure, the wireless hotspot device may construct a management frame containing the SSID and broadcast the management frame outwards.

In general, the communication protocols employed by the target device and the wireless hotspot device are both compliant with the 802.11 standard, where a number of management frames are defined, and thus the management frames may be selected from any of a variety of management frames defined by the 802.11 standard.

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

Taking the example of a beacon frame (probe request frame is the same), a plurality of fields may be included in the beacon frame, one of which is a field for populating the SSID, so the wireless hotspot device may populate the generated SSID into the field to generate the beacon frame.

102. The wireless hotspot device broadcasts a management frame including the generated service set identification.

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

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

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

In practical applications, for a target device, at some point, it may receive not only a 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 all the management frames may include the SSID of the corresponding device. Then the target device needs to distinguish which management frame corresponds to the wireless hotspot device it wants to connect to, i.e. the target device needs to be able to determine from the received management frame sent by the wireless hotspot device that the wireless hotspot device is the device that needs to connect to.

Two alternative implementations are provided below to realize the identification of the target device to the wireless hotspot device to which the target device needs to connect, that is, the target device may determine whether the sending device corresponding to the received management frame is the wireless hotspot device to which the connection needs to be made according to the following two alternative implementations.

The first implementation mode: a particular identifier may be set in a management frame generated by the wireless hotspot device. Thus, if the target device parses the identifier from a received management frame, it is determined that the device that transmits the management frame is a wireless hotspot device that needs to be connected. For example, assuming that a user wants to connect to a smart box (as a wireless hotspot device) in a home with his mobile phone (as a target device), the mobile phone determines that connection to the router is not required and connection to the smart box is required, assuming that the mobile phone can search for SSID including ssid_b from a router adjacent to the home in addition to ssid_a from the smart box, but because management frames sent from the smart box include the above specific identifier, such as ABH, in addition to ssid_a.

The second implementation mode: the target device analyzes the SSID contained in the received management frame to analyze the device identifier contained in the SSID, and 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 length of the device identifier and the first random number constituting the SSID of the wireless hotspot device may be specified in practical applications, the target device may parse the corresponding device identifier from the received SSID according to the length setting. Of course, it will be understood that, for example, if a certain management frame received by the target device is sent by a device that does not need to be connected, such as a router, then part of the field information that is truncated from the SSID of the management frame according to the above length setting case will not exist in the server.

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

Alternatively, the target device may send a first key acquisition request to the server, where the first key acquisition request includes the device identifier and the first random number parsed from the SSID. After receiving the first key obtaining request, the server inquires 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. After receiving the connection request, the wireless hotspot device compares the access key contained in the connection request with the 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 access key, communication connection is established with the target device. It will be appreciated that the encryption algorithm employed by the server to generate the access key described above corresponds to the encryption algorithm employed by the wireless hotspot device.

In summary, through the above scheme, the target device may automatically discover the wireless hotspot device to be connected, and further automatically obtain the access key for accessing the wireless hotspot device, so as to implement automatic connection with the wireless hotspot device, and in the connection process, the user does not need to manually set the SSID, the access key and the operation of inputting the access key of the wireless hotspot device.

It will be appreciated that the purpose of establishing a connection between the target device and the wireless hotspot device is to transfer data information with the wireless hotspot device. The data information transmitted may vary in different application scenarios. 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 to which the wireless hotspot device is expected to access. For another example, in a scenario where the target device controls the operation of the wireless hotspot device, the transmitted data information would be some control instructions, such as a switch instruction, a parameter adjustment instruction, and so forth.

The following is a general description of an embodiment in connection with fig. 2, and provides a solution for securing the transmission of data information, regardless of the data information transmitted.

Fig. 2 is another schematic workflow diagram of a device connection system provided by an embodiment of the present invention, where, 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 hot spot device generates a first random number, generates an SSID according to the device identification of the wireless hot spot device and the first random number, and generates an access key according to the first random number and the private key of the wireless hot spot device.

202. The wireless hotspot device broadcasts a management frame including the generated SSID.

203. And the target equipment determines that the wireless hot-spot equipment is the wireless hot-spot equipment which needs 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. And the server inquires and obtains a private key of the wireless hotspot device according to the device identifier, 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 hot spot equipment according to the access key.

208. The target device generates a second random number.

209. The target device sends a second key acquisition request to the server, wherein the second key acquisition request comprises the device identifier of the wireless hotspot device and a second random number.

210. The server generates an encryption key based on the second random number and a 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 hot spot equipment according to the encryption key.

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

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

In this embodiment, the execution of steps 201-207 may be referred to the description of the other embodiments, and is not repeated here.

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: the private key of the wireless hotspot device and the second random number generated by the target device. Similarly, two key parameters for generating a decryption key corresponding to the encryption key are: the private key of the wireless hotspot device and the 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 then, based on the device identifier parsed from the management frame sent by the wireless hotspot device, a second key acquisition request including the device identifier and the second random number is sent to the server. After receiving the second key acquisition request, the server queries the 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 further 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 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.

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

In addition, in order to further improve the security, the target device may set the 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. And when the life duration is longer, the encryption key and the decryption key are invalid, and if the subsequent target equipment also needs to transmit data information with the wireless hot spot equipment, a new second random number needs to be regenerated.

In summary, based on the scheme provided by the 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.

Taking a network distribution scene as an example, an actual application process of the device connection method provided in the above in the network distribution scene is illustrated. At this time, the wireless hotspot device in the foregoing is a device that needs to perform network configuration, which is called a device to be networked; the target device is a device configured for the wireless hotspot device, referred to as a distribution network device.

Fig. 3 is a 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, generates an SSID according to the device identification of the device to be accessed to the network and the random number, and generates an access key according to the random number and a private key of the device to be accessed to the network.

302. The network-ready device broadcasts a management frame including the SSID.

303. The network distribution equipment determines that the network equipment to be accessed, which sends the management frame, is equipment to be connected according to the received management frame, and acquires an access key according to the equipment identification 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 network-connected by the access key.

305. And the network configuration information of the router is sent to the network equipment to be accessed by the network distribution equipment.

306. The equipment to be accessed to the network 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 the device to be network-accessed. In the hot spot mode, the device to be network-connected needs to start a wifi hot spot function, and broadcasts an SSID of the device to be network-connected to the device to be network-connected by the access key corresponding to the device to be network-connected, and then the device to be network-connected sends network configuration information of a router which hopes to be connected to the device to be network-connected based on communication connection between the device to be network-connected. The network configuration information includes information such as SSID, access PASSWORD (PASSWORD), basic service set identifier (Basic SERVICE SET IDENTIFIER, BSSID) and the like corresponding to the router.

The specific implementation of the above steps may be referred to the related descriptions in the other embodiments, which are not repeated herein. It will be appreciated that the process of obtaining the access key and the encryption key by the network device may be obtained by the request server, and the specific process refers to the relevant description in the foregoing embodiment.

To more intuitively understand the process of network configuration for a device to be network-connected using the hotspot mode, the description is provided with reference to fig. 4.

In fig. 4, it is assumed that the device to be networked is a speaker and the network device is a mobile phone. Assuming that the handset is currently connected to a certain router, the SSID corresponding to the router is expressed as: ssid_a, which is actually the network name of the wireless network corresponding to the router. Assume that the SSID generated by the sound box according to the random number generated by the sound box and the equipment identifier is expressed as: SSID_B, which is actually the network name of the wireless network corresponding to the hot spot where the sound box is opened.

The purpose of the network configuration of the speakers by the handset is to hope that the speakers will be able to access the router to which the handset is currently connected.

As can be seen from fig. 4, to achieve this, first, in an initial state, the handset is connected to the router, i.e. the handset accesses a wireless network with a network name ssid_a.

And then, when a user starts a wifi hotspot function of the sound box, the sound box creates a wireless network with the name SSID_B, and generates an access KEY KEY, so that the SSID_B is broadcasted outwards. The ssid_b includes a device identifier Dev and a random number Rand of the sound box. The access KEY is generated according to the private KEY of the sound box and the random number Rand.

After the SSID_B is detected by the mobile phone, the device identifier Dev and the random number Rand are analyzed from the SSID_B, a server is requested based on the device identifier Dev and the random number Rand to obtain an access KEY of the loudspeaker box, the loudspeaker box is further automatically connected to the loudspeaker box by the access KEY, the connection with the router is disconnected, and the mobile phone is switched to a wireless network with the access network name SSID_B. The device identifier Dev of the server inquires a private KEY of the loudspeaker box, and then generates an access KEY KEY according to the private KEY and the random number Rand.

Based on the connection with the speaker, the mobile phone further issues the network configuration information of the router connected before to the speaker, which is equivalent to the network configuration information required by the mobile phone to inform the speaker of the wireless network with the network name ssid_a, for example, including the network name ssid_a and the access key PASSWD of the router.

The sound box is connected to the wireless network SSID_A based on the received network configuration information, namely, is connected with the router. Thereafter, the handset switches back to wireless network ssid_a.

In summary, when the network configuration is performed on the to-be-network-connected device in the hot spot mode, the automatic connection between the to-be-network-connected device and the network-connected device can be realized through the scheme, manual intervention is not needed, and the efficiency of the network configuration is improved.
