Detailed ways

The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings.

In wireless data transmission based on BLE technology, there are two roles: a slave device and a master device. The slave device can be, for example, a BLE device such as a Bluetooth door lock and a Bluetooth light, and the master device can be a mobile phone, for example. , Tablet computers and other mobile electronic devices.

The following describes the pairing process between BLE devices.

First, establish a link layer (Link Layer, LL) connection between BLE devices;

Specifically, sending broadcast packets (advertising packets) from the device;

In the case of wanting to establish a Bluetooth connection with the slave device, the master device turns on the Bluetooth module, scans the broadcast data packet, and further, the master device sends a connection request to the slave device;

If the slave device receives the connection request from the master device, it can be determined that the master device wants to establish a Bluetooth connection with the slave device, and the slave device returns a connection response to the master device.

At this point, the LL connection is established between the slave device and the master device, during which they use plaintext data for information exchange, that is, non-encrypted data. Among them, the link layer is located in the controller (Controller) part of the BLE protocol stack, and the specific implementation can refer to related technologies, which will not be repeated here.

Further, based on the LL connection, an encrypted link between the BLE devices is established, that is, a pairing process is performed. Mainly divided into three stages:

In the first stage, it is used to exchange pairing features to obtain the temporary key TK, specifically, to exchange authentication requirements (authentication requirements) of the two parties and the human-computer interaction capabilities (IO capabilities) of the two parties;

In the second stage, the TK value of the first stage is used as the secret key of the second stage to calculate the identity confirmation information and generate the short-term key STK, where the identity confirmation value guarantees that the device communicating with itself is the device that needs to be connected to itself , The identity of the other party must be determined. Both the master device and the slave device need to calculate the identity confirmation value to determine whether the other party is the device that needs to be connected. The function of STK is that the third stage of the pairing and binding process no longer uses plaintext for data transmission.

The third stage is the process of device binding. During this period, the long-term keys used in the encrypted link are calculated, such as LTK, IRK, and CSRK. The data transmitted in the third stage passes through the first and second stages. The short-term key is encrypted for transmission. Therefore, the data packet transmitted in the third stage is encrypted ciphertext. The master device and the slave device will save the long-term key, so that the two devices are successfully bound, or paired successfully. After that, the two can exchange data through the long-term key.

Specifically, when there is a plaintext data packet to be sent, the plaintext data needs to be encrypted. The encryption process takes plaintext data packets as input, and uses long-term secret key encryption to generate ciphertext data packets;

When the opposite end receives the ciphertext data packet, it needs to decrypt the ciphertext data packet. The decryption process takes the ciphertext data packet as input and the long-term secret key as the decryption key to generate the plaintext data packet.

It should be understood that the foregoing only exemplifies a pairing process between BLE devices, and the BLE device in the embodiment of the present application may also use other pairing processes for pairing, and the present application is not limited to this.

It can be seen that before the normal data communication between the master device and the slave device, it needs to go through a complicated pairing verification process. For example, if the mobile phone is turned on to control the Bluetooth door lock, the user needs to open the mobile phone’s Bluetooth module and open the control Bluetooth door. The unlocking App of the lock further establishes a connection with the Bluetooth door lock, and the verification is passed to control the opening of the Bluetooth door lock. For the user, the operation is not convenient and the user experience is not good.

In view of this, the embodiments of the present application provide a method for automatic identification, which can configure BLE terminals such as Bluetooth door locks as Human Interface Device (HID), so that BLE devices such as mobile phones are close to the first BLE terminal. At this time, as long as the Bluetooth module of the mobile phone is in the open state, the mobile phone can automatically establish a connection with the Bluetooth door lock, which can further control the opening of the Bluetooth door lock without requiring the user to operate the App, which is conducive to improving the user experience.

Hereinafter, with reference to FIG. 1, a method 200 for automatically identifying an identity according to an embodiment of the present application will be described. The method 200 may be executed by a first BLE terminal, and the first BLE terminal is configured as an HID. The method 200 may include the following contents:

S201. When the second BLE terminal is close to the first BLE terminal, acquire the Media Access Control MAC (Media Access Control) address of the second BLE terminal based on the first Bluetooth connection, where the second BLE terminal is The device bound to the first BLE end;

S202: Determine whether the second BLE end is a trusted device according to the MAC address of the second BLE end;

S203: Determine whether the first BLE terminal performs a preset operation according to whether the second BLE terminal is a trusted device.

It should be understood that the method 200 of the embodiment of the present application can be applied to various BLE devices, such as a BLE chip, or a device including a BLE chip, such as a Bluetooth door lock, a Bluetooth lamp, and the like. The second BLE end may be, for example, a mobile electronic device such as a mobile phone or a tablet, which is not limited in the embodiment of the present application.

In the embodiment of the present application, the first BLE terminal is taken as a slave device, and the second BLE terminal is a master device as an example for description. The first BLE terminal and the second BLE terminal may also be BLE chips.

In the embodiment of the present application, the first BLE end can be configured as HID. For the master device, when receiving a broadcast data packet sent by HID, it actively establishes a connection with the HID, that is, the user does not need to open the control The HID App only needs to keep the Bluetooth module of the main device turned on.

Specifically, the first BLE end can be configured to include HID services, battery (battery) services, and device information (Device Information) services, and the appearance (Appearance) field in the broadcast data packet sent by the first BLE end can be configured. Set to HID.

When the second BLE terminal is close to the first BLE terminal, the second BLE terminal can receive the broadcast data packet sent by the first BLE terminal, and determine that the Appearance field in the broadcast data packet is HID, and the first BLE terminal can be determined The BLE end is HID. Further, the second BLE end may actively establish a first Bluetooth connection with the first BLE end. Specifically, the second BLE end may send a connection request to the first BLE end, The connection response returned by the first BLE terminal is further received to establish the first Bluetooth connection. After that, the second BLE terminal and the first BLE terminal can exchange data through the first Bluetooth connection, for example, obtain all data. The MAC address of the second BLE end. In some embodiments, the connection request may also include key information that is exchanged when the second BLE end and the first BLE end establish a binding relationship, so that the first BLE end can determine the first BLE end The second BLE end is a bound device. In other words, the first BLE end may also determine whether the second BLE end is a trusted device through the MAC address of the second BLE end, or the MAC address of the second BLE segment and the key information . It should be understood that the first Bluetooth connection is an encrypted link, and the data transmitted on the encrypted link may be the long-term key determined when the second BLE end and the first BLE end are paired.

In other embodiments, when a third BLE end that has not established a binding relationship with the first BLE end is close to the first BLE end, the third BLE end may use the pairing process in the foregoing embodiment to establish The binding relationship between the third BLE end and the first BLE end, further, the first BLE end may obtain the MAC address of the third BLE end, so that the third BLE end can approach the third BLE end next time. In the case of the first BLE terminal, the third BLE terminal can actively establish a Bluetooth connection with the first BLE terminal, so that the first BLE terminal can obtain the MAC address of the third BLE terminal based on the Bluetooth connection In order to perform the identity verification of the three BLE ends.

In other embodiments, the first BLE terminal needs to perform password verification to be paired, and the third BLE terminal paired with the first BLE terminal fails the password verification, or fails to connect with the first BLE terminal, or fails to connect with the first BLE terminal. If the pairing of the BLE end fails, all of these may cause the binding of the first BLE end and the third BLE end to fail, and thus the MAC address of the third BLE end cannot be obtained. Taking the first BLE end as a Bluetooth door lock and the third BLE end as a mobile phone as an example, a mobile phone that fails to pair cannot automatically establish a connection with the Bluetooth door lock, and the Bluetooth door lock cannot obtain the MAC address of the mobile phone based on the automatically established connection. .

Further, the first BLE terminal may obtain the MAC address of the second BLE terminal based on the established first Bluetooth connection. For example, the first BLE terminal may use the application program interface (API) of the system. Acquire the MAC address of the second BLE end.

That is to say, when the second BLE end bound to the first BLE end approaches the first BLE end, the second BLE end can automatically establish a connection with the first BLE end, so that the first BLE end A BLE terminal may obtain the MAC address of the second BLE terminal through the connection to determine whether the second BLE terminal is a trusted device.

It should be understood that in this embodiment of the application, the first BLE end may perform identity verification according to the MAC address of the second BLE end, or may also perform identity verification for other identity information that can identify the device. This application does not Limited to this.

In the embodiment of the present application, the MAC address list of the bound device is stored in the first BLE terminal. If the second BLE terminal is a device that has been bound to the first BLE terminal, the first BLE terminal stores the MAC address of the second BLE terminal.

It should be understood that the embodiment of the present application does not specifically limit the manner in which the second BLE end and the first BLE end establish a binding relationship. For example, the pairing process in the foregoing embodiment may be used to establish the binding relationship, or If the binding relationship is established in other ways, the embodiment of the present application is not limited to this.

The MAC address of the second BLE terminal may be stored when establishing a binding relationship with the second BLE terminal, that is, the first BLE terminal may be stored when establishing a binding relationship with the second BLE terminal Acquire and store the MAC address of the second BLE end, for example, obtain the MAC address of the second BLE end through the API of the system, so that when the next connection is made, the second BLE can be verified by the MAC address of the second BLE end Whether the end is credible.

In some embodiments, the first BLE end may determine whether the first BLE end is a trusted device according to whether the MAC address of the second BLE end is in the stored MAC address list.

As an example, if the MAC address of the second BLE end is in the MAC address list, it may be determined that the second BLE end is a trusted device.

As another example, if the MAC address of the second BLE end is not in the MAC address list, it may be determined that the second BLE end is an untrusted device.

As another example, if the MAC address of the second BLE end is not in the MAC address list, the MAC address of the second BLE end may also be saved to the MAC address list, so that the next time the connection is made, the The second BLE terminal can control the first BLE terminal.

Therefore, in the embodiment of the present application, by configuring the first BLE end as HID, when the bound device is close to the first BLE end, the Bluetooth connection with the first BLE end can be automatically established. The MAC address of the device determines whether the device is a trusted device, and when the device is a trusted device, the control of the first BLE end can be achieved. For the bound device, since the MAC address of the device is stored on the first BLE end, the user does not need to operate the device to control the first BLE end, which can improve the user experience.

Optionally, in some other embodiments of the present application, the determining whether the first BLE terminal performs the preset operation according to whether the second BLE terminal is a trusted device includes:

According to whether the second BLE terminal is a trusted device, the signal strength of the second BLE terminal, the time interval between the second BLE terminal being determined to be a trusted device for two consecutive times, and the time of the second BLE terminal At least one of the permissions determines whether the first BLE terminal performs the preset operation.

In some embodiments, the first BLE terminal is a Bluetooth door lock, and the preset operation may be to turn on the Bluetooth door lock, or the first BLE terminal is a Bluetooth light, and the preset operation may be to turn on Bluetooth light, when the preset operation is to turn on the Bluetooth light, when a device that has not been bound to the first BLE terminal approaches the Bluetooth light, the Bluetooth light will not turn on.

In some embodiments, after the second BLE terminal establishes the first Bluetooth connection with the first BLE terminal, the first BLE terminal may check the signal strength of the connection to the second BLE terminal, for example, receive a signal Strength (Received Signal Strength Indicator, RSSI), if the RSSI signal strength is less than a preset value, the first BLE end does not perform the preset operation, for example, if the first BLE end is a Bluetooth door lock, it does not open For the Bluetooth door lock, or if the RSSI signal strength is greater than or equal to a preset value, the first BLE end performs a preset operation, for example, if the first BLE end is a Bluetooth door lock, the Bluetooth door lock is turned on. Determine whether to operate the first BLE terminal according to the signal strength of the connected device, which helps to avoid security problems when the first BLE terminal is turned on when the device is far away from the first BLE terminal, especially in the application of Bluetooth door locks , If the user’s mobile phone is connected to the Bluetooth door lock when the distance is far, and the user’s mobile phone is a device bound to the Bluetooth door lock, the Bluetooth door lock will open when the user is far away, which will bring For security issues, in this embodiment, the preset value can be the RSSI value when the distance between the mobile phone and the door lock is 1m, or the RSSI value when the distance between the mobile phone and the door lock is 0.5m, and the user can adjust the preset value according to needs. This embodiment does not limit this.

In other embodiments, if the time interval during which the second BLE terminal is determined to be a trusted device twice in a row is within the preset time period, it is determined not to operate the first BLE terminal; or

Specifically, the first array and the second array are set. The first array is used to store the information of the devices that have been successfully matched, that is, the information of the devices whose MAC addresses are in the MAC address list, or that are determined to be trusted devices. Device information, the second array is used to store the time count value after the device in the first array is successfully matched.

For example, if the device A is close to the first BLE end, the first BLE end determines that the MAC address of the device A is in the MAC address list, that is, the device A is successfully matched, then it searches in the first array to determine whether it has been matched before. Device A, if the device A is found in the first array, the time count value corresponding to the device A is obtained in the second array, that is, the time interval from the last successful match to the current successful match, If the time count value is less than or equal to the preset duration, for example, 5 minutes, the first BLE terminal does not perform the preset operation, or if the time count value is greater than the preset duration, the first BLE terminal performs the preset operation, Further, the time count value corresponding to the device A in the second array can also be cleared.

Therefore, determining whether the first BLE terminal performs a preset operation according to the time interval during which a device is continuously matched is beneficial to avoid misoperation caused when the device continuously appears near the first BLE terminal. For example, in the application scenario of a Bluetooth door lock, if a user is holding a mobile phone and hovering near the Bluetooth door lock, and the user’s mobile phone is a device bound to the Bluetooth door lock, the Bluetooth door lock will frequently perform opening operations, but the user’s The real intention is not to open the Bluetooth door lock. In this embodiment, it is helpful to avoid the above-mentioned problem by configuring that the consecutive successful matching within a certain period of time does not trigger the unlocking operation. Optionally, in some embodiments, the time interval may be 10 minutes or half an hour, and the user may also adjust the time interval according to requirements, which is not limited in this embodiment.

In some embodiments, each bound device may correspond to a corresponding time authority. For example, the MAC address list includes the MAC addresses of five devices, and the five devices may correspond to corresponding time authority. For example, device A corresponds to The time permission of is permanent, the time permission corresponding to device B is 10 days, the time permission corresponding to device C is 1 day, etc.

In this way, after it is determined that the MAC address of the device connected to the first BLE end is in the MAC address list, it can be further combined with the time authority of the device to determine whether the first BLE end performs a preset operation, for example, if the Within the time authority of the device, it can be determined that the first BLE terminal performs the preset operation, such as opening the Bluetooth door lock, otherwise the first BLE terminal does not perform the preset operation, for example, does not open the Bluetooth door lock, so that it can Realize the fine control of different devices on the first BLE end.

In other embodiments, the first BLE end may also update the MAC address list in combination with the time authority of the device, and when the time authority of a certain device is exceeded, the MAC address of the device is cleared from the MAC address list. , The devices in the updated MAC address list are all devices within the time authority, and the first BLE terminal can directly determine whether to operate the first BLE terminal according to the MAC address list. For example, the first BLE terminal is a Bluetooth door lock, and 5 mobile phones are bound to the Bluetooth door lock, but only one of the 5 mobile phones has the long-term unlock time permission, and the other devices have only 3 days time permission . When the mobile phone and the Bluetooth door lock are automatically connected to obtain the MAC address of the mobile phone, the Bluetooth door lock can learn the time authority of the mobile phone. If the time authority has expired, the corresponding MAC address of the mobile phone can be deleted from the MAC address list, and at the same time The mobile phone that is successfully paired with the Bluetooth door lock may also have a key list. After the time authority of the mobile phone expires, the Bluetooth door lock may also delete the key paired with the mobile phone from the key list.

In the following, with reference to FIG. 2, from the perspective of the master device and the slave device, the overall flow of the method for automatic identification of the embodiment of the present application is described, but the embodiment of the present application is not limited to this.

S301. The slave device sends a broadcast data packet, where the Appearance field in the broadcast data packet is HID.

Correspondingly, when the master device approaches the slave device, it can scan the broadcast data packet. According to the Appearance field in the broadcast data packet as HID, it can be determined that the slave device is HID, and the Bluetooth connection with the slave device can be established. .

S302: The slave device determines whether to establish a connection with the master device.

In case 1, the master device is a bound device, and when the master device is close to the slave device, the master device can actively establish a Bluetooth connection with the slave device.

Case 2: The master device is an unbound device, and the user can also manually operate the master device to establish a Bluetooth connection with the slave device.

Case 3: If no master device is close to the slave device, then no master device establishes a connection with the slave device.

If a connection is established between the slave device and the master device, execute S303, otherwise return to S301.

Further, in S303, the slave device determines whether the master device and the slave device are bound.

If yes, go to S305, otherwise go to S304.

As an example, the master device and the slave device may determine whether they are bound by exchanging key information. For example, the master device may send to the slave device the key information saved when the binding relationship was established. The slave device can verify the key information to determine whether the master device and the slave device are bound.

In S304, the slave device disconnects from the master device.

That is, for the master device that has not established a binding relationship, it can be determined that it must be an untrusted device, and the slave device can disconnect its Bluetooth connection.

Or, in other embodiments, the slave device may also establish the binding relationship between the slave device and the master device through the pairing process described above, so as to execute the subsequent process.

In S305, the slave device obtains the MAC address of the master device.

For example, the slave device may obtain the MAC address of the master device through the API of the system.

Further, in S306, it is determined whether the MAC address of the master device is in the stored MAC address list.

If yes, execute S308, otherwise, execute S307.

S307: Store the MAC address in the MAC address list, and further execute S308.

In S308, it is determined that the main device is a trusted device.
