[0066] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] With the rapid increase in the number of access layer devices, the issues of concurrent cloud server traffic and secure device access have become increasingly prominent. Currently, most methods on the market involve scanning a device's QR code to bind it to a cloud device via a mobile application. However, QR codes are easily leaked through methods such as taking photos, and the security of device access cannot be guaranteed. Therefore, this application provides a device access method, apparatus, and electronic device.

[0068] This application provides a method for device network access, which can be applied to handheld devices, such as... Figure 1 As shown, the handheld device can scan terminal devices located in different locations and upload the scanned NFC information to the server. The terminal devices can then connect to the cloud server, such as... Figure 2 As shown, the device network access method may include the following steps:

[0069] Step S101: Scan the first NFC tag of the device to be connected to the network to obtain the device's NFC information;

[0070] In this embodiment, the device to be connected to the network can refer to any end device to be connected to the network, such as: lamps, elevators, air conditioners, etc. The device to be connected to the network is equipped with a first NFC tag. The first NFC tag can be built into the device to be connected to the network. A handheld device can scan the designated area on the outside of the device to be connected to the network corresponding to the first NFC tag to obtain the device's NFC information; or, the first NFC tag can also be affixed to the outer surface of the device to be connected to the network. A handheld device can scan the designated area on the outer surface of the device to be connected to the network corresponding to the first NFC tag to obtain the device's NFC information.

[0071] like Figure 3 As shown, the device NFC information includes: a first NFC unique identifier, a device unique identifier, a device network access public key, and device attribute information.

[0072] Step S102: Scan the second NFC tag corresponding to the location of the device to be connected to the network to obtain the location NFC information;

[0073] In this embodiment of the application, the location of the device to be connected to the network can refer to the physical location of the device to be connected to the network. For example, it can refer to the location of a room, etc. Each location for placing the device to be connected to the network can be equipped with a second NFC tag. The second NFC tag can be affixed to the surface of the wall, door, etc., corresponding to the location for placing the device to be connected to the network. The handheld device can scan the designated area where the second NFC tag is located to obtain the location NFC information.

[0074] like Figure 4 As shown, the location NFC information includes: a second NFC unique identifier, a location unique identifier, and physical location information.

[0075] Step S103: Send the device NFC information and the location NFC information to the cloud server so that the cloud server can perform network access verification based on the device NFC information. When the network access verification of the device to be accessed is successful, the device to be accessed is connected to the network, and the device NFC information and the location NFC information are bound together.

[0076] As the number of connected devices increases, maintaining the correspondence between the devices and the geographical locations of rooms in the building during the debugging process becomes a time-consuming and labor-intensive task, and it is also prone to matching errors. Therefore, it is necessary to bind the device NFC information and location NFC information of devices that have passed network access verification to the cloud server.

[0077] This application embodiment obtains device NFC information by scanning a first NFC tag of the device to be connected to the network, and obtains location NFC information by scanning a second NFC tag corresponding to the location of the device. Both are then sent to a cloud server. When the device passes network access verification, the cloud server connects the device to the network and binds the device NFC information and the location NFC information. On one hand, NFC technology ensures the security of the device NFC information from the source. Furthermore, the cloud server only connects the device to the network after successful network access verification of the device NFC information, achieving more secure network access. On the other hand, it enables the mapping between devices and addresses, improving the efficiency of maintaining the correspondence between device locations and ensuring the accuracy of the correspondence, thereby improving the efficiency of device positioning.

[0078] In another embodiment of this application, the method further includes:

[0079] Step S201: Scan the first original NFC tag corresponding to the end device whose NFC information is to be established to obtain the first NFC unique identifier;

[0080] In this embodiment of the application, the first original NFC tag may refer to an NFC tag that has not been written with the device's unique identifier, device network access public key, device attribute information, etc., while it refers to an NFC tag containing the first NFC unique identifier.

[0081] Step S202: Perform a one-way encryption operation on the first NFC unique identifier to obtain the first MD5 encrypted data;

[0082] One-way encryption operation is to use a one-way encryption algorithm to perform encryption calculation on the first NFC unique identifier.

[0083] Step S203: Obtain the first scanning moment when scanning the first original NFC tag;

[0084] Step S204: Perform encryption operation on the first scan time and the first MD5 encrypted data to obtain the second MD5 encrypted data;

[0085] In this step, a second one-way encryption operation can be performed on the first scan time and the first MD5 encrypted data to obtain the second MD5 encrypted data.

[0086] Step S205: Determine the second MD5 encrypted data as the device unique identifier of the terminal device;

[0087] Step S206: Obtain the device access public key corresponding to the terminal device for which the NFC information of the device to be established is to be established;

[0088] In one embodiment of this application, step S206, obtaining the device access public key corresponding to the end device for which NFC information to be established is to be acquired, includes:

[0089] 1. Send a public key acquisition request and the device's unique identifier to the cloud server, so that the cloud server returns public key data and stores the device's unique identifier locally on the cloud server;

[0090] 2. If public key data is received from the cloud server, the public key data is encrypted using the device's unique identifier to obtain the device's network access public key.

[0091] In this step, the handheld device uses AES+RSA encryption to encrypt the public key data as the content to be encrypted, and uses the device's unique identifier as the encryption key to encrypt the public key data. The resulting data, which can be decrypted in reverse, is written into the first original NFC tag of the terminal device as the device's network access public key.

[0092] Step S207: Determine the device NFC information corresponding to the end device for which device NFC information is to be established based on the first NFC unique identifier, the device unique identifier, and the device network access public key.

[0093] In this step, the first NFC unique identifier, the device unique identifier, and the device network access public key (such as device attribute information) can be used as the device NFC information corresponding to the end device.

[0094] The embodiments of this application can obtain the device's NFC information in advance through NFC technology and encryption technology, thereby improving the security of the device's NFC information.

[0095] In another embodiment of this application, the method further includes:

[0096] Step S301: Scan the second original NFC tag corresponding to the location of the location NFC information to be established to obtain the second NFC unique identifier;

[0097] In this embodiment of the application, the second original NFC tag may refer to an NFC tag that has not written with a unique location identifier and the physical location information, and the second original NFC tag only contains a second NFC unique identifier.

[0098] Step S302: Perform a one-way encryption operation on the second NFC unique identifier to obtain the third MD5 encrypted data;

[0099] One-way encryption operation is to use a one-way encryption algorithm to perform encryption calculation on the second NFC unique identifier.

[0100] Step S303: Obtain the second scanning moment when scanning the second original NFC tag;

[0101] Step S304: Perform encryption operation on the second scan time and the third MD5 encrypted data to obtain the fourth MD5 encrypted data;

[0102] In this step, a second one-way encryption operation can be performed on the second scan time and the third MD5 encrypted data to obtain the fourth MD5 encrypted data.

[0103] Step S305: Determine the fourth MD5 encrypted data as the unique identifier of the location;

[0104] Step S306: Obtain the physical location information of the location;

[0105] Step S307: Determine the location NFC information corresponding to the location of the location NFC information to be established based on the second NFC unique identifier, the location unique identifier, and the physical location information.

[0106] In this step, the second NFC unique identifier, the location unique identifier, and the physical location information can be used as the device NFC information corresponding to the end device.

[0107] The embodiments of this application can obtain location NFC information in advance through NFC technology and encryption technology, thereby improving the security of location NFC information.

[0108] In another embodiment of this application, a device network access method is also provided, applied to a cloud server, such as... Figure 5 As shown, the method includes:

[0109] Step S401: Receive device NFC information and location NFC information of the device to be connected to the network from the handheld device;

[0110] Step S402: Perform network access verification on the device to be connected to the network based on the device's NFC information;

[0111] In one embodiment of this application, step S402 performs network access verification on the device to be connected to the network based on the device's NFC information, including:

[0112] Step S501: Extract the device's unique identifier and network access public key from the device's NFC information;

[0113] Step S502: If no device unique identifier matching the device unique identifier is found locally, it is determined that the network access verification of the device to be accessed has failed.

[0114] If no device unique identifier matching the device unique identifier is found on the local cloud server, it indicates that the device unique identifier was not previously entered and uploaded by the handheld device, and it can be determined that the network access verification of the device corresponding to the device unique identifier has failed.

[0115] Step S503: If a device unique identifier that is the same as the device unique identifier is found locally, the device unique identifier is used to decrypt the device network access public key to obtain the connection public key.

[0116] If a device unique identifier identical to the device's unique identifier is found locally on the cloud server, it indicates that the device unique identifier was previously entered and uploaded by the handheld device. The next step of verification can then be performed, which involves verifying the connection public key. This involves comparing the decrypted connection public key with the original connection public key pre-stored on the cloud server. If the two are the same, the connection public key verification is confirmed to be successful.

[0117] Step S504: If the connection public key verification is successful, it is determined that the network access verification of the device to be connected to the network has been successful;

[0118] If further verification of the connection public key still passes, it can be determined that the network access verification of the device corresponding to the device's unique identifier has been successful.

[0119] Step S505: If the connection public key verification fails, it is determined that the network access verification of the device to be connected to the network has failed.

[0120] If further verification of the connection public key fails, it can be determined that the network access verification of the device corresponding to the device's unique identifier has failed.

[0121] Step S403: If the network access verification of the device to be connected to the network is successful, the device to be connected to the network is connected.

[0122] Step S404: Bind the device NFC information and the location NFC information.

[0123] This application embodiment verifies the network access of the device to be connected to the network based on the device's NFC information. When the network access verification is successful, the device is connected to the network, and the device's NFC information and the location NFC information are bound together. On the one hand, NFC technology can ensure the security of the device's NFC information from the source. Moreover, the cloud server only allows the device to connect to the network when the network access verification of the device's NFC information is successful, thus achieving more secure network access for the device. On the other hand, it can realize the mapping between devices and addresses, improve the efficiency of maintaining the correspondence between device locations, ensure the accuracy of the correspondence, and thus improve the efficiency of device positioning.

[0124] In another embodiment of this application, after the device to be connected to the network is connected to the network, the method further includes:

[0125] Step S601: If a location query request for querying the physical location of any network-connected device is received, the location NFC information corresponding to the device NFC information of the network-connected device is searched in the binding relationship between the device NFC information and the location NFC information.

[0126] Step S602: Generate a location query response based on the physical location information in the location NFC information and return it.

[0127] In this embodiment, the binding relationship between device NFC information and location NFC information can be fully utilized. When a location query request for the physical location of any network-connected device is received, the physical location information of the network-connected device can be automatically found and returned, thereby improving the efficiency of device positioning.

[0131] The first sending module 13 is used to send the device NFC information and the location NFC information to the cloud server, so that the cloud server performs network access verification based on the device NFC information. When the network access verification of the device to be accessed passes, the device to be accessed is connected to the network, and the device NFC information and the location NFC information are bound together.
