The computer program may be integrated into the application or may run as a separate tool-like application. The pairing connection device in the embodiment of the present application may be an electronic device.
Please refer to fig. 1, which is a flowchart illustrating a pairing connection method according to an embodiment of the present disclosure. As shown in fig. 1, the method of the embodiment of the present application may include the steps of:
s101, when the electronic equipment is communicated with Bluetooth equipment for the first time, a pairing function supported by the Bluetooth equipment and an identifier of the Bluetooth equipment are obtained on the basis of 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 a pairing mode. After pairing, the appointed link key is established between the devices by the PIN code, and after pairing, the subsequent communication connection does not need to be paired every time, and the connection can be established according to the link key only by authentication. Therefore, the two devices cannot establish an authentication relationship without pairing, connection and subsequent operation cannot be performed, and the safety of Bluetooth communication is ensured to a certain extent through pairing.
In the embodiment of the application, one of the devices is an electronic device, and the other device is a bluetooth device. Both devices have a Bluetooth function and can complete 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 used to provide a medium for communication links between the electronic devices 101, 102, 103 and the bluetooth device 105.
Among them, bluetooth is a radio technology supporting short-range communication (generally within 10 m) of devices, and can perform wireless information exchange among a plurality of devices including mobile phones, PDAs, wireless headsets, notebook computers, related peripherals, and the like. By using the Bluetooth technology, the communication between the terminal devices can be effectively simplified, and the communication between the devices and the Internet can also be successfully simplified, so that the data transmission becomes faster and more efficient, and the way is widened for wireless communication.
It should be understood that the number 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, as desired for implementation. For example, the bluetooth device 105 may be a bluetooth device cluster formed by a plurality of bluetooth devices, or a plurality of independent bluetooth devices within a certain distance, etc.
A user may use the electronic devices 101, 102, 103 to interact with the bluetooth device 105 over the bluetooth network 104 to receive or send messages, etc. The electronic devices 101, 102, 103 may be various electronic devices having a display screen, including but not limited to smart phones, tablets, laptops, desktops, bluetooth headsets, bluetooth car mounts, bluetooth headsets, bluetooth MP3, bluetooth flash drives, bluetooth adapters, bluetooth gateways, bluetooth CF cards, and the like. The bluetooth device may include, but is not limited to, a bluetooth headset, a bluetooth car, a bluetooth headset, a bluetooth MP3, a bluetooth flash disk, a bluetooth adapter, a bluetooth gateway, a bluetooth CF card, 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 established, the electronic equipment acquires the pairing function supported by the Bluetooth equipment from the Bluetooth equipment through the link and acquires the identifier of the Bluetooth equipment through the link, so that the authentication and pairing can be completed based on the supported pairing function and the equipment identifier. The identifier is used for uniquely identifying the bluetooth device, and may be a device name or the like. It will be appreciated that the identification is derived based on a bluetooth address for presentation to the user.
The ACL link is a logical link of connection-oriented bluetooth asynchronous transmission. The data packets are sent directionally over the link, which supports both symmetric and asymmetric connections (either one-to-one or one-to-many). The master device (electronic device) is responsible for controlling the link bandwidth and decides how much bandwidth each slave device (bluetooth device) can occupy and the symmetry of the connection. The slave device can only transfer data if it is selected. The ACL link also supports the reception of broadcast messages sent by the master device to all slave devices. In addition, the ACL link is mainly used for transfer of packet data.
S102, performing security authentication on the electronic device and the Bluetooth device, and completing pairing connection based on a pairing connection mode corresponding to the security simple pairing function and the Bluetooth device indicated by the identification when the pairing function is determined to include the security simple pairing function after the security authentication is passed.
As any wireless communication technology has the possibility of being monitored and cracked, in order to ensure the safety of Bluetooth communication, data interaction is carried out in an authentication mode.
The bidirectional authentication is by challenge-response (challenge-response) means. As shown in fig. 3, the electronic device a is the responder and the bluetooth device B is the requester. The a device, which is the responder, generates a 128-bit random number AU _ RANDA and transmits it in clear to the B device. A. The B device uses the E1 algorithm to generate the 32-bit SRESA and SRESB respectively from the AU _ RANDA, Kab and BD _ ANDRB encryption operations obtained respectively. The device B transmits the result SRESB to the device a, which compares the SRESA and the SRESB, and if equal, the authentication passes, otherwise the authentication does not pass. After the authentication is performed, the roles of the device a and the device B are exchanged, that is, the device a serves as a requester and the device B serves as a responder, and the authentication is performed in the same manner. And after the two parties pass the authentication, confirming that the security authentication passes.
After the authentication is passed, whether a Secure Simple Pairing (SSP) function is included in Pairing functions supported by the bluetooth device is judged, if yes, a required function is determined in the supported Pairing functions according to a Pairing connection mode corresponding to the SSP function, and Pairing connection is completed with the bluetooth device indicated by the identifier.
SSP uses a more elaborate mechanism, called elliptic curve cryptography, to avoid using PIN codes as part of the link key calculation process, and instead uses extremely large random numbers to seed the link key calculation. Therefore, the number of possible link keys is no longer limited to a probability of less than 2^128, which far exceeds the capability of any real attacker, and the security is high.
To achieve this, the SSP process begins with the establishment of heterogeneous shared secrets between two devices. This shared secret, called the Diffie-Hellman key, is a 192-bit random number. As a prerequisite, the two devices each have a private key and a public key. The public key is propagated over the air and can be known by anyone, but the private key is never disclosed. These two keys are referred to as SSP public/private Key pairs, but these are also referred to as Diffie-Hellman public/private Key pairs.
In the embodiment of the application, when the electronic device and the bluetooth device are paired and connected for the first time, the electronic device does not execute the RNR operation before creating the ACL link, but directly creates the ACL link first, and after the ACL is successfully created, the electronic device acquires the support function and the RNR operation of the bluetooth device of the opposite party, records whether the bluetooth device of the opposite party supports the SSP function, and then performs the operations of pairing authentication and connection service. By integrating the RNR operation performed before the creation of the formal ACL and the RNR operation performed after the creation of the formal ACL into one operation and deleting redundant operations, the time required to perform the RNR operation at one time can be reduced, so that the pairing connection speed can be increased.
Please refer to fig. 2, which is a flowchart illustrating a pairing connection method according to an embodiment of the present disclosure. The pairing connection method may include the steps of:
s201, when the electronic equipment communicates with Bluetooth equipment for the first time, under the condition that a temporary asynchronous connection-oriented link is not established, initiating a connection request to the Bluetooth equipment to establish the asynchronous connection-oriented link;
first, an electronic device (master, i.e. a device initiating connection) pages a bluetooth device (slave, a device receiving connection), the master pages the slave in a frequency hopping manner, the slave scans an external page at regular intervals, and when the external page is scanned, the slave responds to the external page, so that a link connection, i.e. an ACL link connection, is established between the electronic device and the bluetooth device.
The timeout time for page is 40.9 seconds maximum and 0.625ms minimum. And when the Bluetooth device does not return Page Response within the non-Timeout time, returning a Page Timeout event.
The bluetooth device can only respond to the connection request of other bluetooth devices by starting the page scan mode. The page scan is a state, and the electronic device may be successfully connected only if the bluetooth device is in the page scan state.
The Page Scan comprises three parameters of Page Scan Interval, Page Scan Windows and Page Scan Type.
Here, Page Scan Interval represents how often the Interval is equal to, and the maximum value is 2560 ms.
Page Scan Windows indicates how long Scan lasts once, which is less than or equal to Interval.
There are two types of Page Scan Type, one is a mandatory standard Type and the other is an optional Interlace Type.
Under the condition that the temporary asynchronous connection-oriented link is not established, the pairing function supported by the Bluetooth device and the identification of the Bluetooth device do not need to be acquired based on the temporary asynchronous connection-oriented link, whether the safe and simple pairing function is supported or not is recorded based on the supported pairing function, and the temporary asynchronous connection-oriented link is disconnected.
Optionally, after the electronic device communicates with the bluetooth device for the first time, an environmental interference value needs to be obtained, and when the environmental interference value is greater than or equal to an interference threshold, the pairing function supported by the bluetooth device and the identifier of the bluetooth device are obtained based on the created asynchronous connection-oriented link. When the environmental interference value is smaller than an interference threshold value, a temporary asynchronous connection-oriented link needs to be established, a pairing function and an identifier of the Bluetooth device supported by the Bluetooth device are obtained based on the temporary asynchronous connection-oriented link, whether a safe and easy pairing function is supported or not is recorded based on the supported pairing function, the temporary asynchronous connection-oriented link is disconnected, and then the pairing function and the identifier of the Bluetooth device supported by the Bluetooth device are obtained based on the established asynchronous connection-oriented link in a triggering mode.
That is, when the environmental interference is large, the steps of S101-102 are adopted to perform the connection, and since a connection speed can be obtained without establishing the temporary asynchronous connection-oriented link, the problem of slow connection caused by the large environmental interference can be reduced.
S202, acquiring the pairing function supported by the Bluetooth equipment through the created asynchronous connection-oriented link;
the electronic equipment sends a function acquisition request to the Bluetooth equipment through the created ACL link, and receives a response message fed back by the Bluetooth equipment based on the function acquisition request, wherein the response message carries the pairing function supported by the Bluetooth equipment.
S203, judging whether the pairing function comprises a safe simple pairing function and recording;
traversing the received pairing function, and determining whether an SSP function exists, if so, recording as yes, otherwise, recording as no.
S204, acquiring the identifier of the Bluetooth equipment through the asynchronous connection-oriented link;
and sending an identification acquisition request to the Bluetooth equipment through the created ACL link, and receiving the identification of the Bluetooth equipment fed back by the Bluetooth equipment based on the identification acquisition request.
The identification is a device name.
It can be understood that the electronic device requests the bluetooth device to obtain the Name of the bluetooth device through the ACL link based on the bluetooth address of the bluetooth device, and after receiving the request, the bluetooth device returns the Name to the electronic device for display, thereby completing an rnr (remote Name request) operation. The user can distinguish different bluetooth devices more friendly by the name.
For example, as shown in fig. 5, the electronic device requests the bluetooth device with bluetooth address 10:4E:89:9D:3B: C8 to obtain the device name, and the bluetooth device feeds back the name of the electronic device as "my headset" as shown in fig. 6.
S205, performing 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 safe and simple pairing function, completing pairing connection with the Bluetooth device based on a pairing connection mode corresponding to the safe and simple pairing function and the pairing function;
bidirectional authentication uses a challenge-response approach. For a specific authentication process, see S102, which is not described herein.
After the authentication is passed, whether the pairing function supported by the Bluetooth device comprises an SSP function is judged, if yes, the required function is determined in the supported pairing function according to a pairing connection mode corresponding to the SSP function, and the pairing connection is completed with the Bluetooth device indicated by the identification.
Of course, if the security authentication fails, the pairing connection cannot be completed.
The secure Pairing connection Mode can be broadly divided into two types of Legacy Security Modes (1, 2, 3, also called Legacy Pairing) and Security Mode 4 (i.e., SSP). The device may support Security Mode 2 and Security Mode 4 simultaneously.
The several modes are specifically: security Mode 1: Non-Security; security Mode 2, Service level enabled Security; security Mode 3 is Link level enhanced Security; security Mode 4: Service level enhanced Security.
SSP uses a more elaborate mechanism, called elliptic curve cryptography, to avoid using PIN codes as part of the link key calculation process, and instead uses extremely large random numbers to seed the link key calculation. Therefore, the number of possible link keys is no longer limited to a probability of less than 2^128, which far exceeds the capability of any real attacker, and the security is high. SSP is a Bluetooth 2.0 after pairing mode, and there are four types in total, of which Out of Band is rarely used, as follows:
number company: both paired parties display a 6-digit number, the user checks whether the numbers are consistent and inputs Yes/No, and Yes at both ends shows consistency, thus the pairing can be realized, and man-in-the-middle attack can be prevented.
The use scenario is as follows: the two-terminal device may pop up a 6 digit decimal number and have yes and no buttons.
Passkey Entry: the pairing target inputs a 6-digit number displayed on the local equipment, and the pairing can be realized if the input is correct, and the man-in-the-middle attack can be prevented.
The use scenario is as follows: one end device may display and the other end device may input.
Just Works: authentication cannot be performed, man-in-the-middle attack cannot be prevented from being used for pairing equipment which is not displayed and has no input, pairing can be performed by actively initiating connection, a user cannot see the pairing process, and man-in-the-middle attack cannot be prevented, such as connection of a Bluetooth headset.
The use scenario is as follows: for devices that cannot display nor input 6-bit random numbers.
Out of Band: the two devices exchange pairing information through other ways, such as some NFC bluetooth speakers.
In this embodiment of the application, when the recording result indicates that the pairing function includes a safe and easy pairing function, the pairing mode is selected based on a specific use scenario of the electronic device and the bluetooth device.
S206, when the pairing function does not comprise the safe simple pairing function, the pairing connection with the Bluetooth equipment is completed based on a default pairing connection mode and the pairing function.
When the SSP is not included, the pairing is performed by adopting any pairing Mode supported by the electronic equipment (namely, the Security Mode 1, the Security Mode 2 or the Security Mode 3). Of course, if the device supports multiple pairing connection modes, the device may select according to the order of priority of each mode, so as to complete pairing connection with the bluetooth device.
Legacy Security models are used for bluetooth v2.0 and earlier, the device needs to input Pin Code, and when the Pin Code is the same, the pairing is successful. Pin Code is typically 4 bytes, such as 0000 and 1234.
It should be noted that, through verification, in general, by adopting the scheme, the speed of the first pairing connection can be increased by about 300ms to 800 ms; in extreme cases, namely when the interference of the surrounding environment is strong, the connection speed can be increased by 4s or more by adopting the scheme.
In the embodiment of the application, when the electronic device is paired and connected with the bluetooth device for the first time, the electronic device does not execute the RNR operation before creating the ACL link, but directly creates the ACL link first, and after the ACL is successfully created, the electronic device acquires the support function of the bluetooth device of the opposite party and the RNR operation, records whether the bluetooth device of the opposite party supports the SSP function, and then performs the pairing authentication and service connection operation. The RNR operation executed before the formal ACL is created and the RNR operation executed after the formal ACL is created are integrated into one operation, redundant operation is deleted, the time required for executing the RNR operation once can be shortened, particularly when the electronic equipment and the Bluetooth equipment are in an environment with strong interference, the pairing connection speed can be improved, and better use experience is brought to a user.
