Description

Technical Field

[0001] The embodiments of this disclosure generally relate to the field of wireless communication, and more specifically to a Wi-Fi-sensing-based distribution network method. Background Technology

[0002] Currently, most smart hardware products on the market are based on Wi-Fi communication. These Wi-Fi devices typically lack a user interface, unlike personal computers and mobile phones, which provide users with an interface to select and connect to Wi-Fi hotspots. To enable these user-uninterrupted smart devices to connect to the network, the problem of correctly connecting them to a router must first be solved. In other words, it is necessary to solve the problem of how to securely and reliably transmit information used for router connection, such as the wireless network's SSID (Service Set Identifier) ​​and access password, to these smart devices. This invention aims to solve this problem.

[0003] For these smart hardware devices that lack a human-computer interaction interface, there are currently two main methods for network configuration:

[0004] The first method is to set the smart hardware to Soft AP mode, that is, set the mobile phone to Station mode, and then use the mobile phone to connect to the Soft AP on the smart hardware. After the connection is successful, the SSID and password of the wireless access point are transmitted to the smart device. After receiving the SSID and password of the wireless access point, the smart device switches from Soft AP mode back to Station mode and uses the received SSID and password of the wireless access point to connect to the wireless access point to complete the network configuration.

[0005] The second method involves setting the smart hardware to promiscuous mode, in which it can receive qualified wireless packets. On the mobile phone, the SSID and access password are encoded into a UDP (User Datagram Protocol) packet and transmitted via wireless broadcast or multicast. Upon receiving the wireless packet, the smart hardware decodes it to obtain the correct SSID and access password, and then uses this information to connect to the wireless access point, completing network configuration.

[0006] The traditional Soft AP network configuration and promiscuous mode network configuration methods described above are slow and have poor security. Especially when faced with the need to configure multiple smart devices simultaneously, the network configuration efficiency is very low. Their main disadvantages include the following:

[0007] Poor user experience: While the Soft AP-based network configuration method can guarantee successful configuration, the user experience is not user-friendly because this method requires the mobile phone to connect to the Soft AP first, whether manually (iOS) or automatically (Android), and then switch back after configuration. The whole operation process is very cumbersome and complicated.

[0008] Poor security and low success rate: Although smart configuration is convenient, there is a certain probability of failure in complex Wi-Fi environments. The mobile phone has to transmit the router password to the Wi-Fi module. If it is in plaintext, it can be easily intercepted, thus posing a great security risk to the Wi-Fi network.

[0009] Slow speed: When using Soft AP and promiscuous mode for network configuration, each device needs to interact with the cloud and complete the binding process one by one. A single network configuration usually takes about 10 seconds. If there are dozens or even hundreds of devices to be configured, the configuration time will be very long. Summary of the Invention

[0018] Preferably, step d) further includes: the anchoring master device sending a second encrypted ciphertext to the mobile terminal, the second encrypted ciphertext being ciphertext obtained by encrypting configuration information and network key according to the second shared key.

[0041] In the following description and claims, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Some exemplary embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0042] Before introducing the embodiments of this disclosure, the basic concepts to be applied in this invention will be explained in order to better explain the implementation process of the solutions of this disclosure.

[0043] Wi-Fi Aware Protocol: The Wi-Fi Aware protocol is a neighboring device discovery protocol customized by the Wi-Fi Alliance based on the IEEE 802.11 protocol. This protocol works on IEEE 802.11 devices, but it is not an enhancement or revision of the IEEE 802.11 standard, and Wi-Fi Aware only requires IEEE 802.11 end-device manufacturers to modify and upgrade their driver software. The Wi-Fi Aware function enables devices to discover each other and connect directly without any other type of connection between them. Wi-Fi Aware is also known as a Neighborhood Aware Network (NAN).

[0044] Neighbor Awareness Network Cluster (NAN Cluster): A Neighbor Awareness Network Cluster is a collection of multiple adjacent devices that share a common set of NAN parameters, are synchronized with the same discovery window time schedule, and have a unique NAN Cluster ID.

[0045] NAN Devices: Devices that support the implementation of the NAN protocol. NAN devices can function as either a Master or a Non-Master. In a NAN cluster, the highest-priority Master is the Anchor Master, which maintains timing for a synchronized cluster, and other NAN devices in the cluster must adhere to its Time Synchronization Function (TSF). Every NAN device in a NAN cluster should have the capability to become an Anchor Master. Devices that inherit the title of Anchor Master must maintain their original TSF.

[0046] Furthermore, devices that support Wi-Fi sensing can autonomously detect, alert, and connect to other devices without needing a Wi-Fi access point (AP). Specifically, Wi-Fi sensing applications can be configured to alert users to nearby devices running the same application. Wi-Fi sensing discovery can be based on various parameters such as distance; for example, alerting the user when another device running the same application is less than 10 feet (approximately 3.048 meters) away. Applications can also be configured to establish a secure, point-to-point data connection with another device for application data exchange.

[0047] Example 1

[0048] Figure 1 This diagram illustrates a proximity sensing network cluster composed of multiple Wi-Fi-sensing devices. Figure 1 As shown, multiple devices awaiting network configuration enable Wi-Fi sensing service and negotiate to form a proximity sensing network cluster. Among these devices, the one with the highest Master priority is elected as the AnchorMaster, while the remaining devices (e.g., device A, device B, ..., device N) are non-AnchorMaster devices. The AnchorMaster can send beacon frames to allow other devices seeking to join the proximity sensing network cluster to discover it, and these other devices can reply with Wi-Fi sensing frames to allow the AnchorMaster to discover them as well.

[0049] Figure 2 This shows the addition of mobile terminals, such as Figure 1 The diagram illustrates a proximity sensing network cluster. When a mobile terminal enables Wi-Fi sensing service, it joins the cluster, which consists of multiple devices awaiting network configuration, upon receiving a beacon frame from the cluster. As an example and not a limitation, the mobile terminal can be a smartphone, tablet, laptop, or other mobile device that supports Wi-Fi sensing service.

[0050] As an example, and not a limitation, the mobile terminal obtains distribution network information. The mobile terminal may obtain the distribution network information in advance through human-computer interaction, or through any other applicable method.

[0051] Figure 3 A schematic diagram illustrates the communication process between any device to be distributed to the network, the anchoring master device, and the mobile terminal, in order to ultimately achieve the purpose of network distribution.

[0052] A. The anchoring master device distributes the distribution key to the device to be distributed.

[0053] Step S110: The device to be configured on the network negotiates with the anchor master device to obtain a first shared key. Here, the device to be configured on the network has not yet obtained a network configuration key. As an example and not a limitation, the anchor master device and the device to be configured on the network negotiate and calculate the first shared key using a symmetric key algorithm.

[0054] Step S114: The anchoring master device generates a network configuration key. As an example and not a limitation, the anchoring master device can generate the network configuration key in a random manner.

[0055] Step S116: The anchoring master device encrypts the distribution key according to the first shared key to obtain the first encrypted ciphertext.

[0056] Step S118: The anchoring master device sends the first encrypted ciphertext to the device to be distributed.

[0057] Step S134: The device to be configured decrypts the received first encrypted ciphertext according to the first shared key, thereby obtaining the configuration key.

[0058] As an example and not a limitation, the process of the anchoring master device distributing the network distribution key to the device to be configured may also include the following steps:

[0059] Step S112: The device to be configured sends configuration information to the anchor master device.

[0060] It is worth noting that, unless otherwise specified, the steps of the above method are not limited in the order of execution. For example, step S112 can be performed before or after any of steps S114 to S134.

[0061] As an example, and not a limitation, step S112 can be performed when the device to be configured on the network has just joined the proximity sensing network cluster. Alternatively, this step can be performed at any other suitable time. Figure 4 The diagram illustrates how a device in a proximity sensing network cluster sends configuration information to an anchoring master device via Wi-Fi sensing frames.

[0062] For example, the anchoring master device can organize and save the configuration information of all devices to be configured after receiving Wi-Fi sensing frames from each device to be configured.

[0063] In some embodiments, the Wi-Fi sensing frame can be a publish frame, a follow-up frame, or a subscribe frame, and all of these sensing frames can carry custom information.

[0064] As an example and not a limitation, in step S110, the device to be configured and the anchor master device negotiate to obtain the first shared key, including: establishing a data channel and calculating the first shared key through a key negotiation algorithm; wherein the key negotiation can be based on the four-way handshake of the pairwise secure key negotiation process in NAN to negotiate the key, or it can be generated through asymmetric encryption algorithms such as DH, RSA, or ECC.

[0065] As an example, and not a limitation, the configuration information may include address information for each device to be configured, such as MAC address information. As an example, and not a limitation, the configuration information may also include encrypted access information, indicating whether the device to be configured has encrypted access configured. If the device to be configured has encrypted access configured, it indicates that the device has a private key configured. Furthermore, the configuration information may also include configuration information obtained by the anchoring master device from other devices to be configured in the neighboring sensing network cluster, such as address information and encrypted access information of the other devices to be configured.

[0066] As an example and not a limitation, the above method and steps for the anchored master device to distribute the network distribution key to the device to be configured can be further extended to any device to be configured that has already obtained the network distribution key to distribute the network distribution key to other devices to be configured. After the device to be configured decrypts the first encrypted ciphertext according to the first shared key to obtain the network distribution key and the address information of at least one device to be configured that has not obtained the network distribution key, the following steps are performed to distribute the network distribution key to at least one device to be configured that has not obtained the network distribution key:

[0067] (1) At least one device to be configured without a configuration key negotiates with at least one device to be configured that has a configuration key to obtain a corresponding first shared key;

[0068] (2) At least one device to be configured without obtaining a configuration key obtains a corresponding first encrypted ciphertext from at least one device to be configured that has obtained a configuration key. The corresponding first encrypted ciphertext is the ciphertext obtained by encrypting the configuration key according to the corresponding first shared key.

[0069] (3) At least one device to be configured to receive network data that has not obtained the network key shall decrypt the corresponding first encrypted ciphertext according to the corresponding first shared key in order to obtain the network key.

[0070] As described above, in this scenario, firstly, the device that has obtained the network configuration key negotiates with the device to be configured to obtain a first shared key. Secondly, the device that has obtained the network configuration key encrypts the network configuration key according to the first shared key to obtain a first encrypted ciphertext. Then, the device that has obtained the network configuration key sends the first encrypted ciphertext to the device to be configured. The device to be configured decrypts the received first encrypted ciphertext according to the first shared key, thereby obtaining the network configuration key. Further optimized, the device that has obtained the network configuration key can also send the configuration information of other devices in the proximity sensing network cluster to be configured, such as address information and encryption access information, obtained from the anchoring master device. This distribution method facilitates the rapid acquisition of network configuration keys for multiple devices in the proximity sensing network cluster. Compared to the previous method where the anchoring master device needs to connect to the device to be configured and send the network configuration key each time, this optimized method can exponentially improve the distribution speed of the network configuration key.

[0071] B. The anchoring master device sends configuration information and network configuration key to the mobile terminal.

[0072] Step S120: The anchoring master device negotiates with the mobile terminal to obtain the second shared key.

[0073] Step S122: The anchoring master device encrypts the distribution key according to the second shared key to obtain the second encrypted ciphertext.

[0074] Step S124: The anchored master device sends the second encrypted ciphertext to the mobile terminal.

[0075] Step S126: The mobile terminal decrypts the second encrypted ciphertext according to the second shared key to obtain the network configuration key.

[0076] Further optimized, in step S126, the mobile terminal decrypts the second encrypted ciphertext according to the second shared key to obtain the network configuration key and network configuration information. Here, by example and not limitation, the configuration information may include the address information of each device to be configured, such as MAC address information. By example and not limitation, the configuration information may also include encryption access information, indicating whether the device to be configured is configured with encryption access. If the device to be configured is configured with encryption access, it indicates that the device to be configured has a private key.

[0077] It is worth noting that, unless otherwise specified, the steps of the above method are not limited in the order of execution. For example, the communication steps between the mobile terminal and the anchoring master device can be executed via Wi-Fi sensing frames.

[0078] C. The mobile terminal sends network distribution information to the device to be networked.

[0079] Step S128: The mobile terminal obtains the network distribution information.

[0080] Step S130: The mobile terminal encrypts the obtained network configuration information according to the network configuration key to obtain the third encrypted ciphertext.

[0081] Step S132: The mobile terminal sends a third encrypted ciphertext to at least one device to be configured on the network.

[0082] As an example rather than a limitation, mobile terminals can obtain network distribution information through human-computer interaction.

[0083] In another embodiment, after the mobile terminal completes step S132 above, if the device to be configured for network access is configured with encryption access control, the following steps are also performed: obtaining the private key of the device to be configured for network access control, and performing a calculation on the private key and the network access control key to obtain an updated network access control key; and encrypting the network access control information according to the updated network access control key to obtain a third encrypted ciphertext. If the device to be configured for network access control is not configured with encryption access control, the following steps are performed: encrypting the network access control information according to the network access control key to obtain a third encrypted ciphertext.

[0084] As an example, and not a limitation, a mobile terminal can obtain the private key of a device to be configured by scanning a QR code on the device, or by having the user enter the private key on the mobile terminal, or by anchoring to a master device. Alternatively, the mobile terminal can also obtain the private key of a device to be configured by scanning other identifiable code patterns on the device. Each device configured with encrypted access has a unique private key.

[0085] It is worth noting that, unless otherwise specified, the steps of the above method are not limited in the order of execution. For example, the communication steps between the mobile terminal and the device to be configured on the network can be executed via Wi-Fi sensing frames.

[0086] D. The device to be distributed obtains distribution network information.

[0087] As described above, the device to be configured executes step S134 to obtain the configuration key: at least one device to be configured obtains a third encrypted ciphertext from the mobile terminal. The third encrypted ciphertext is the ciphertext obtained by encrypting the configuration information obtained by the mobile terminal according to the configuration key.

[0088] After receiving the third encrypted ciphertext sent from the mobile terminal, the device to be configured further executes step S136: at least one device to be configured decrypts the third encrypted ciphertext according to the configuration key to obtain the configuration information.

[0089] In another embodiment, after receiving the third encrypted ciphertext from the mobile terminal, if the device to be configured for network configuration has encrypted access control, it further performs the following steps: performing a calculation on the private key and the network configuration key to obtain an updated network configuration key, and decrypting the third encrypted ciphertext according to the updated network configuration key to obtain network configuration information. If the device to be configured for network configuration has not been configured for encrypted access control, it performs the following step: decrypting the third encrypted ciphertext according to the network configuration key to obtain network configuration information.

[0090] As an example and not a limitation, after obtaining network configuration information, the device to be configured scans for the target router and connects to it using the network configuration information to complete the network configuration. Optionally, the device to be configured may send a Wi-Fi sensing frame to the mobile terminal to notify the mobile terminal to stop sending other Wi-Fi sensing frames.

[0091] Example 2

[0092] Figure 5 A schematic diagram of the communication process between any device to be distributed to the network, the anchoring master device, and the mobile terminal in another embodiment is shown to ultimately achieve the purpose of network distribution.

[0093] Step S210: The device to be configured with the network negotiates and obtains a first shared key with the anchor master device. Here, the device to be configured with the network has not yet obtained a network configuration key. As an example and not a limitation, the anchor master device and the device to be configured with the network negotiate and calculate the first shared key using a symmetric key algorithm.

[0094] Step S212: The device to be configured sends configuration information to the anchor master device. This configuration information, by way of example and not limitation, may include address information for each device to be configured, such as MAC address information. The configuration information also includes encryption access information, indicating whether the device to be configured has encryption access configured. If the device to be configured has encryption access configured, it indicates that the device to be configured has a private key.

[0095] Step S214: The anchoring master device generates a network configuration key. As an example and not a limitation, the anchoring master device can generate the network configuration key in a random manner.

[0096] Step S216: The anchoring master device encrypts the distribution key according to the first shared key to obtain the first encrypted ciphertext.

[0097] Step S218: The anchoring master device sends the first encrypted ciphertext to the device to be distributed.

[0098] Step S220: The anchoring master device negotiates with the mobile terminal to obtain the second shared key.

[0099] Step S222: The anchoring master device encrypts the configuration information and the distribution key according to the second shared key to obtain the second encrypted ciphertext.

[0100] Step S224: The anchoring master device sends the second encrypted ciphertext to the mobile terminal.

[0101] Step S226: The mobile terminal decrypts the second encrypted ciphertext according to the second shared key to obtain configuration information and network configuration key.

[0102] Step S228: The mobile terminal obtains the network distribution information.

[0103] Step S230: The mobile terminal determines whether the device to be configured for network access is configured with encrypted access based on the configuration information.

[0104] If the device to be configured for network access is configured with encrypted access, then step S230a is executed: obtain the private key of the device to be configured for network access, and perform a calculation on the private key and the network access key to obtain an updated network access key; and encrypt the network access information according to the updated network access key to obtain a third encrypted ciphertext.

[0105] If the device to be configured for network distribution is not configured with encrypted access, then execute step S230b: encrypt the network distribution information according to the network distribution key to obtain the third encrypted ciphertext.

[0106] Step S232: The mobile terminal sends a third encrypted ciphertext to the device to be configured on the network.

[0107] Step S234: The device to be configured decrypts the received first encrypted ciphertext according to the first shared key, thereby obtaining the configuration key.

[0108] If the device to be configured for network access is configured with encrypted access, then step S236a is executed: the device to be configured performs a calculation on the private key and the network access key to obtain an updated network access key, and decrypts the third encrypted ciphertext according to the updated network access key to obtain the network access information.

[0109] If the device to be configured for network distribution is not equipped with encrypted access, then step S236b is executed: the device to be configured for network distribution decrypts the third encrypted ciphertext according to the network distribution key to obtain the network distribution information.

[0110] As an example and not a limitation, after obtaining network configuration information, the device to be configured scans for the target router and connects to it using the network configuration information to complete the network configuration. Optionally, the device to be configured may send a Wi-Fi sensing frame to the mobile terminal to notify the mobile terminal to stop sending other Wi-Fi sensing frames.

[0111] It is worth noting that, unless otherwise specified, the steps of the above method are not limited in the order of execution.

[0112] For example, the communication steps between the device to be configured, the anchoring master device, and the mobile terminal can be executed through a Wi-Fi sensing frame.
