In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application, as recited in the appended claims.

The pairing connection method provided by the embodiment of the present application will be described in detail below with reference to FIG. 1 to FIG. 6 . The method can be implemented by relying on a computer program, and can be run on a paired connection device based on the von Neumann system. The computer program can be integrated into an application or run as a stand-alone utility application. Wherein, the pairing and connecting device in the embodiment of the present application may be an electronic device.

Please refer to FIG. 1 , which is a schematic flowchart of a pairing connection method provided by an embodiment of the present application. As shown in FIG. 1 , the method of the embodiment of the present application may include the following steps:

S101, when the electronic device communicates with a Bluetooth device for the first time, obtain a pairing function supported by the Bluetooth device and an identifier of the Bluetooth device based on the created asynchronous connection-oriented link;

In order to ensure the convenience of use, the first communication authentication between two Bluetooth devices is completed in the form of pairing. After pairing, a PIN code is used to establish an agreed link key between devices. After pairing, the subsequent communication connection does not need to be paired every time, and only requires authentication to establish a connection based on the link key. Therefore, without pairing, the authentication relationship cannot be established between the two devices, and the connection and subsequent operations cannot be performed. The security of Bluetooth communication is guaranteed to a certain extent through pairing.

In this embodiment of the present application, one of the devices is an electronic device, and the other device is a Bluetooth device. Both devices have Bluetooth function and can complete the pairing connection.

As shown in FIG. 2 , the system architecture 100 may include one or more of electronic devices 101 , 102 , 103 , a Bluetooth network 104 and a Bluetooth device 105 . The Bluetooth network 104 is a medium used to provide a communication link between the electronic devices 101 , 102 , 103 and the Bluetooth device 105 .

Among them, Bluetooth is a radio technology that supports short-distance communication (generally within 10m) of devices, and can exchange wireless information among many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. The use of Bluetooth technology can effectively simplify the communication between terminal devices, and can also successfully simplify the communication between the device and the Internet, so that data transmission becomes more rapid and efficient, and the road for wireless communication is widened.

It should be understood that the numbers of electronic devices, Bluetooth networks and Bluetooth devices in FIG. 2 are merely illustrative. There may be any number of electronic devices, Bluetooth networks, and Bluetooth devices depending on the implementation needs. For example, the Bluetooth device 105 may be a Bluetooth device cluster composed of multiple Bluetooth devices or multiple independent Bluetooth devices within a certain distance range.

The user may use the electronic devices 101, 102, 103 to interact with the Bluetooth device 105 through the Bluetooth network 104 to receive or send messages and the like. The electronic devices 101, 102, 103 can be various electronic devices with display screens, including but not limited to smart phones, tablet computers, portable computers, desktop computers, Bluetooth headsets, Bluetooth car, Bluetooth headsets, Bluetooth MP3, Bluetooth flash drives, Bluetooth adapter, Bluetooth gateway, Bluetooth CF card, etc. The bluetooth devices may include but are not limited to bluetooth headsets, bluetooth vehicles, bluetooth headsets, bluetooth MP3s, bluetooth flash drives, bluetooth adapters, bluetooth gateways, bluetooth CF cards and the like.

When an electronic device is paired with a Bluetooth device, an ACL link needs to be created first. After the ACL link is created, the electronic device obtains the pairing function supported by the Bluetooth device from the Bluetooth device through the link, and obtains the identity of the Bluetooth device through the link, so as to follow-up based on the supported pairing function and The device ID is authenticated and paired. The identifier is used to uniquely identify the Bluetooth device, and may be a device name or the like. It can be understood that the identifier is obtained based on the Bluetooth address and used for displaying to the user.

Among them, the ACL link is a logical link of connection-oriented Bluetooth asynchronous transmission. Data packets are sent directionally through this link, which supports both symmetric and asymmetric connections (that is, one-to-one or one-to-many). The master device (electronic device) is responsible for controlling the link bandwidth and deciding how much bandwidth each slave device (Bluetooth device) can occupy and the symmetry of the connection. A slave can only transmit data when it is selected. The ACL link also supports receiving broadcast messages from the master device to all slave devices. In addition, the ACL link is mainly used for the transmission of packet data.

S102: Perform security authentication on the electronic device and the Bluetooth device, and after the security authentication is passed, when it is determined that the pairing function includes a secure and simple pairing function, based on the pairing connection mode corresponding to the secure and simple pairing function and The pairing function completes the pairing connection with the Bluetooth device indicated by the identification.

Since any wireless communication technology has the possibility of being monitored and cracked, in order to ensure the security of Bluetooth communication, data exchange is carried out by means of authentication.

Two-way authentication is through the challenge-response (challenge-response) method. As shown in FIG. 3 , the electronic device A is the responder, and the Bluetooth device B is the requester. The A device as the responder generates a 128-bit random number AU_RANDA and transmits it to the B device in clear text. Devices A and B both use the E1 algorithm to encrypt AU_RANDA, Kab and BD_ANDRB to generate 32-bit SRESA and SRESB respectively. Device B transmits the result SRESB to device A. Device A compares SRESA and SRESB. If they are equal, the authentication passes this time, otherwise the authentication fails. After the authentication is performed, the roles of device A and device B are reversed, that is, device A is the requester and device B is the responder, and the authentication is performed in the same way. After both authentications are passed, the security authentication is confirmed.

After the authentication is passed, determine whether the pairing functions supported by the Bluetooth device include the Secure Simple Pairing (SSP) function. If so, determine the supported pairing functions according to the pairing connection mode corresponding to the SSP function. To complete the pairing connection with the bluetooth device indicated by the identifier.

SSP uses a more elaborate mechanism, called elliptic curve cryptography, that avoids using a PIN code as part of the link key calculation process, and instead uses a very large random number to seed the link key calculation. Therefore, the number of possible link keys is no longer limited to the possibility of less than 2^128, which is far beyond the capabilities of any realistic attacker, and the security is high.

To achieve this, the SSP process begins by establishing a different kind of shared secret between the two devices. This shared secret is called the Diffie-Hellman key and is a 192-bit random number. As a prerequisite, both devices each have a private and public key. The public key is spread over the air and can be known by anyone, but the private key is never revealed. Call these two keys SSP public/private key pairs, but these are also called Diffie-Hellman public/private key pairs.

In the embodiment of the present application, when the electronic device is paired and connected with the Bluetooth device for the first time, the electronic device does not perform the RNR operation before creating the ACL link, but directly creates the ACL link first. The Bluetooth device supports functions and RNR operations, and records whether the other party's Bluetooth device supports the SSP function, and then performs pairing authentication and connection service operations. By integrating the RNR operation performed before the formal ACL is created and the RNR operation performed after the formal ACL is created into one, and removing redundant operations, the time required to perform the RNR operation once can be reduced, thereby improving the pairing connection speed.

Please refer to FIG. 2 , which is a schematic flowchart of a pairing connection method provided by an embodiment of the present application. The pairing connection method may include the following steps:

S201, when the electronic device communicates with the Bluetooth device for the first time, without establishing a temporary asynchronous connection-oriented link, initiate a connection request to the Bluetooth device to create an asynchronous connection-oriented link;

First, the electronic device (master, the device that initiates the connection) will page (page) the Bluetooth device (slave, the device that receives the connection), the master will page the slave by frequency hopping, and the slave will scan at regular intervals (page scan). ) external paging, when scan to an external page, it will respond to the page, so that a link connection is established between the electronic device and the Bluetooth device, that is, the connection of the ACL link.

The maximum timeout of page is 40.9 seconds and the minimum is 0.625ms. When the Bluetooth device does not return the Page Response within the time-out period, the Page Timeout event is returned.

Among them, only when the Bluetooth device turns on the page scan mode, it can respond to the connection requests of other Bluetooth devices. Pagescan is a state, and only when the Bluetooth device is in the page scan state can the electronic device be connected successfully.

Page Scan includes: Page Scan Interval (paging scan interval), Page Scan Windows (paging scan window) and Page Scan Type (type) three parameters.

Among them, the Page Scan Interval indicates how often the scan interval is equivalent, and the maximum value is 2560ms.

Page Scan Windows indicates how long the scan lasts. This value should be less than or equal to the value of Interval.

There are two types of Page Scan Type, one is the mandatory standard type, and the other is the optional Interlace (interlace) type.

In the case where a temporary asynchronous connection-oriented link is not established, it is not necessary to obtain the pairing function supported by the Bluetooth device and the identity of the Bluetooth device based on the temporary asynchronous connection-oriented link. Records whether the secure easy pairing function is supported and disconnects the temporary asynchronous connection-oriented link.

Optionally, after the electronic device communicates with the Bluetooth device for the first time, it is also necessary to obtain the environmental interference value, and when the environmental interference value is greater than or equal to the interference threshold, trigger the acquisition based on the asynchronous connection-oriented link created. The pairing function supported by the Bluetooth device and the identity of the Bluetooth device. When the environmental interference value is less than the interference threshold, a temporary asynchronous connection-oriented link needs to be established, and the pairing function supported by the Bluetooth device and the identity of the Bluetooth device are obtained based on the temporary asynchronous connection-oriented link. The supported pairing function records whether it supports the safe and simple pairing function and disconnects the temporary asynchronous connection-oriented link, and then triggers the execution of the acquisition of the pairing function supported by the Bluetooth device based on the created asynchronous connection-oriented link. and the identity of the Bluetooth device.

That is to say, when the environmental interference is large, the steps of S101-102 are used for connection. Since a temporary asynchronous connection-oriented link is not established, a faster connection speed can be obtained, which can reduce the slow connection caused by the large environmental interference. question.

S202, obtain the pairing function supported by the Bluetooth device through the created asynchronous connection-oriented link;

The electronic device sends a function acquisition request to the Bluetooth device through the created ACL link, and receives a response message fed back by the Bluetooth device based on the function acquisition request, where the response message carries the pairing function supported by the Bluetooth device .

S203, determine whether the pairing function includes a safe and simple pairing function and record it;

That is, it traverses the received pairing functions to confirm whether there is an SSP function. If it exists, it is recorded as yes, otherwise, it is recorded as no.

S204, obtaining the identity of the Bluetooth device through the asynchronous connection-oriented link;

Send an identity acquisition request to the Bluetooth device through the created ACL link, and receive the identity of the Bluetooth device fed back by the Bluetooth device based on the identity acquisition request.

The identifier is the device name.

It can be understood that the electronic device requests the Bluetooth device to obtain the name of the Bluetooth device based on the Bluetooth address of the Bluetooth device through the ACL link. After the Bluetooth device receives the request, it returns the name to the electronic device for display, completing an RNR (Remote Name Request) operate. Users can distinguish different Bluetooth devices more friendly by this name.

For example, as shown in Figure 5, the electronic device requests the device name from the Bluetooth device whose Bluetooth address is 10:4E:89:9D:3B:C8, and the name of the Bluetooth device fed back to the electronic device is "my headset", such as shown in Figure 6.

S205, perform security authentication on the Bluetooth device based on the identifier, and after the security authentication is passed, when it is determined that the pairing function includes a secure and simple pairing function, based on the pairing connection mode corresponding to the secure and simple pairing function and all The pairing function completes the pairing connection with the Bluetooth device;

The two-way authentication adopts the challenge-response (challenge-response) method. For the specific authentication process, reference may be made to S102, which will not be repeated here.

After the authentication is passed, it is judged whether the pairing function supported by the Bluetooth device includes the SSP function. the Bluetooth device to complete the pairing connection.

Of course, if the security authentication fails, the pairing connection cannot be completed.

The secure pairing connection mode can be roughly divided into two Legacy Security Modes (1, 2, 3, also known as Legacy Pairing) and Security Mode 4 (ie SSP). A device may support both Security Mode 2 and Security Mode 4.

These modes are specifically: Security Mode 1: Non-secure; Security Mode 2: Service level enforced security; Security Mode 3: Link level enforced security; Security Mode 4: Service level enforced security.

SSP uses a more elaborate mechanism, called elliptic curve cryptography, that avoids using a PIN code as part of the link key calculation process, and instead uses a very large random number to seed the link key calculation. Therefore, the number of possible link keys is no longer limited to the possibility of less than 2^128, which is far beyond the capabilities of any realistic attacker, and the security is high. SSP is a pairing method after Bluetooth 2.0. There are four kinds of them. Out of Band is rarely used. The details are as follows:

Numeric Comparison: Both sides of the pairing display a 6-digit number, and the user checks whether the numbers are consistent, and input Yes/No. Yes at both ends means the pairing can be done, which can prevent man-in-the-middle attacks.

Usage scenarios: Devices at both ends can pop up 6-digit decimal numbers, and have yes and no buttons.

Passkey Entry: The pairing target enters a 6-digit number displayed on the local device, and the input is correct to pair and prevent man-in-the-middle attacks.

Usage scenario: One end device can display, and the other end device can input.

Just Works: No authentication is performed, and man-in-the-middle attacks cannot be prevented. It is used to pair devices that do not display no input. It can be paired by actively initiating a connection. The user cannot see the pairing process. It cannot prevent man-in-the-middle attacks, such as connecting a Bluetooth headset.

Usage scenario: Used for devices that can neither display 6-bit random numbers nor input them.

Out of Band: The two devices exchange pairing information through other means, such as some NFC Bluetooth speakers.

In the embodiment of the present application, when the recording result is that the pairing function includes a safe and simple pairing function, the pairing method is selected based on the specific usage scenario of the electronic device and the Bluetooth device.

S206, when it is determined that the pairing function does not include the safe and simple pairing function, complete a pairing connection with the Bluetooth device based on a default pairing connection mode and the pairing function.

When the SSP is not included, any pairing method supported by the electronic device (ie, Security Mode 1, Security Mode 2, or Security Mode 3) is used for pairing. Of course, if the device supports multiple pairing connection modes, it can be selected according to the priority order of each mode, so as to complete the pairing connection with the Bluetooth device.

Legacy Security Modes are used for Bluetooth v2.0 and earlier versions. The device needs to enter the Pin Code. When the Pin Code of both parties is the same, the pairing is successful. Pin Code is usually 4 bytes, such as 0000 and 1234.

It should be noted that, through verification, in general, using this solution, the speed of the first pairing connection can be increased by about 300ms to 800ms; in extreme cases, that is, when the surrounding environment interference is strong, using this solution, The speed of the connection can be increased by about 4s, or even more.

In the embodiment of the present application, when the electronic device is paired and connected with the Bluetooth device for the first time, the electronic device does not perform the RNR operation before creating the ACL link, but directly creates the ACL link first. The Bluetooth device supports functions and RNR operations, and records whether the other party's Bluetooth device supports the SSP function, and then performs pairing authentication and connection service operations. By integrating the RNR operation performed before the formal ACL is created and the RNR operation performed after the formal ACL is created into one, and removing redundant operations, the time required to perform an RNR operation can be reduced, especially when the electronic device is in interference with the Bluetooth device. In a relatively strong environment, the pairing connection speed can be improved, bringing a better user experience to the user.

In the embodiment of the present application, when the electronic device is paired and connected with the Bluetooth device for the first time, the electronic device does not perform the RNR operation before creating the ACL link, but directly creates the ACL link first. The Bluetooth device supports functions and RNR operations, and records whether the other party's Bluetooth device supports the SSP function, and then performs pairing authentication and connection service operations. By integrating the RNR operation performed before the formal ACL is created and the RNR operation performed after the formal ACL is created into one, and removing redundant operations, the time required to perform an RNR operation can be reduced, especially when the electronic device is in interference with the Bluetooth device. In a relatively strong environment, the pairing connection speed can be improved, bringing users a better experience.
