[0057] FIG2a is a flow chart of a communication connection method provided by an embodiment of the present disclosure. The method is executed by a first device. As shown in FIG2a , the communication connection method may include the following steps:

[0058] Step 201a: Receive first information broadcast by a second device, where the first information includes a pairing code.

[0059] Optionally, in some embodiments, the second device may be a device to which the first device is to be connected for communication. For example, the second device may be a device to which the first device is to be connected via Bluetooth and / or NFC.

[0060] Optionally, in some embodiments, the first information may include a pairing code. Optionally, the pairing code may be a pairing code corresponding to the second device, and the pairing code is used to connect the first device to the second device.

[0061] Step 202a: Request the second device to establish a communication connection based on the pairing code.

[0062] Optionally, in some embodiments, the method in which a first device requests a second device to establish a communication connection based on a pairing code may include the following steps: transmitting the pairing code in a connection establishment request to the second device to request the second device to establish a communication connection. Optionally, after receiving the connection establishment request from the first device, the second device may first verify the first device based on the pairing code in the connection establishment request, and upon successful verification, establish a communication connection with the first device. A detailed description of the second device verifying the first device will be provided in subsequent embodiments related to the second device.

[0063] Referring to the contents of steps 201a-202a above, it can be seen that in the communication connection method of the embodiment of the present disclosure, when the first device wants to connect to the second device, the first device can obtain the first information broadcast by the second device, which includes a pairing code. The first device can then directly achieve communication connection with the second device based on the pairing code. Therefore, it can be seen that the communication connection method of the embodiment of the present disclosure is achieved by the interaction between the first device and the second device, without the need for user intervention. Therefore, the present disclosure provides a method for seamless connection between devices, which is highly efficient, convenient to operate, and can also improve the user experience.

[0064] In summary, in the communication connection method provided in the embodiment of the present disclosure, a first device receives a first message broadcast by a second device, wherein the second device includes a pairing code; the pairing code is used to connect the first device to the second device; and the first device requests the second device to establish a communication connection based on the pairing code. It can be seen that the communication connection method in the embodiment of the present disclosure is implemented by the interaction between the first device and the second device, without the need for user intervention. Therefore, the present disclosure provides a method for seamless connection between devices, which is highly efficient, convenient to operate, and can also enhance the user experience.

[0065] FIG2 b is a flow chart of a communication connection method provided by an embodiment of the present disclosure. The method is executed by a first device. As shown in FIG2 , the communication connection method may include the following steps:

[0066] Step 201b: Receive the first information broadcast by the second device, where the first information is information obtained by encrypting the pairing code using the first key.

[0067] Optionally, in some embodiments, the second device may be a device to which the first device is to be connected for communication. For example, the second device may be a device to which the first device is to be connected via Bluetooth and / or NFC.

[0068] Optionally, in some embodiments, the first information may be information obtained by encrypting the pairing code using the first key. Optionally, the first key may be pre-configured in the first device and the second device. For example, the first key may be generated by a server and then sent to the first device and the second device; or, the first key may be pre-written to the first device or the second device through factory preset or other trusted means. Optionally, the pairing code may be the pairing code corresponding to the second device, which is used to connect the first device to the second device.

[0069] Optionally, in some embodiments, the method for the second device to encrypt the pairing code using the first key may include the following steps:

[0070] Step 1: The second device randomly generates a decimal pairing code (000000-999999) and converts the decimal pairing code into a hexadecimal (0x000000-0x0f423f) 4-byte Big-Endian plaintext pairing code plainPairingCode;

[0071] Step 2: The second device randomly generates a 4-byte random number IV or agrees on a fixed 4-byte IV with the first device in advance, and uses the SHA256 algorithm to obtain a nonce based on the IV;

[0072] Step 3: Use the first key (secret) to encrypt the plaintext pairing code plainPairingCode and nonce using the AES-128-CTR algorithm to obtain a 4-byte ciphertext pairing code cipherPairingCode; where cipherPairingCode = AES_128_CTR (secret, plainPairingCode, nonce). This cipherPairingCode can be understood as the first information mentioned above.

[0073] Step 4: If the IV is a random number, the IV and the cipherPairingCode may be concatenated to generate an 8-byte ciphertext, which is then broadcast as part of the broadcast data (e.g., broadcast in an agreed manner);

[0074] Step 5: If IV is agreed data, directly broadcast the cipherPairingCode as part of the broadcast data (eg, broadcast in an agreed manner).

[0075] Therefore, the second device can encrypt the pairing code with the first key by executing steps 1 to 5 above to generate the first information and broadcast it.

[0076] Step 202b: Determine the first key.

[0077] Optionally, in some embodiments, the method for the first device to determine the first key may include at least one of the following:

[0078] receiving the first key sent by the server;

[0079] A first key pre-configured (eg, factory configured or written in other trusted ways) in the first device is determined.

[0080] Step 203b: Request the second device to establish a communication connection based on the pairing code.

[0081] Optionally, in some embodiments, the method in step 203b whereby the first device requests the second device to establish a communication connection based on the pairing code may include the following steps:

[0082] Step a: Decrypt the first information using the first key to obtain a pairing code.

[0083] Optionally, the method for the first device to decrypt the first information using the first key to obtain the pairing code can be: first extract the IV from the broadcast data of the second device or determine the IV as agreed, and then use the first key to decrypt the first information. Referring to the encryption process of the second device in steps 1-5 above, it can be seen that the first information includes a plainPairingCode and a nonce. Based on this, after decrypting the first information, the first device can first use the SHA256 algorithm to obtain the nonce based on the IV. The information excluding the nonce in the decrypted first information is the above-mentioned plainPairingCode, and the pairing code can be obtained based on the plainPairingCode.

[0084] Step b: sending the pairing code in a connection establishment request to the second device to request the second device to establish a communication connection.

[0085] Optionally, after receiving the connection establishment request from the first device, the second device may first verify the first device based on the pairing code in the connection establishment request, and if the verification is successful, establish a communication connection with the first device. The details of the second device verifying the first device will be described in detail in the subsequent embodiments corresponding to the second device side.

[0086] With reference to the contents of steps 201b-203b above, it can be seen that in the communication connection method of the embodiment of the present disclosure, when the first device wants to connect to the second device, the first device can obtain the first information broadcast by the second device, the first information includes a pairing code, and the first information is encrypted by the first key. In addition, the first device will also determine the first key, and will decrypt the first information by the first key to obtain the pairing code, and then realize the communication connection with the second device based on the pairing code. It can be seen that the communication connection method of the embodiment of the present disclosure is realized by the interaction between the first device and the second device, without the need for user intervention. The present disclosure provides a method for seamless connection between devices, which is highly efficient, convenient to operate, and can also enhance user experience.

[0087] Furthermore, in the communication connection method of the embodiment of the present disclosure, the first device encrypts the pairing code to obtain the first information and then broadcasts the first information. This can avoid the pairing code from being directly exposed to the communication environment, thereby preventing the pairing code from being maliciously intercepted by other devices and improving the security of the communication connection.

[0088] In summary, in the communication connection method provided by the embodiment of the present disclosure, the first device will receive the first information broadcast by the second device, wherein the second device is the device to which the first device wants to communicate and connect, and the first information is: information obtained after encrypting the pairing code using the first key; the pairing code is used for the first device to connect to the second device; and the first device will also determine the first key, and will request the second device to establish a communication connection based on the pairing code. It can be seen that the communication connection method of the embodiment of the present disclosure is implemented by the interaction between the first device and the second device, without the need for user intervention. The present disclosure provides a method for seamless connection between devices, which is highly efficient, convenient to operate, and can also improve user experience. In addition, in the communication connection method of the embodiment of the present disclosure, the first device encrypts the pairing code to obtain the first information and then broadcasts the first information, thereby avoiding the pairing code from being directly exposed to the communication environment, thereby preventing the pairing code from being maliciously intercepted by other devices, and improving the security of the communication connection.

[0089] FIG3 is a flow chart of a communication connection method provided by an embodiment of the present disclosure. The method is executed by a first device. As shown in FIG3 , the communication connection method may include the following steps:

[0090] Step 301: Determine the identity resolving key (IRK).

[0091] Optionally, in one embodiment of the present disclosure, when broadcasting the first information, the second device may use a resolvable private address (RPA) to broadcast the first information, and the IRK determined in step 301 may be the IRK corresponding to the RPA when the second device broadcasts the first information, and the IRK may be used to resolve the RPA. Optionally, in some embodiments, the above-mentioned IRK may be pre-written to the first device in a trusted manner, for example, it may be sent to the first device by a server, or it may be written to the first device through factory preset or other trusted methods.

[0092] The following is a detailed introduction to the reasons for introducing RPA and IRK, and the relationship between RPA and IRK.

[0093] Among them, the reason why the second device uses RPA to broadcast the first information in the embodiment of the present disclosure is mainly so that the first device can successfully identify (or discover) the second device. Specifically, for the first device, it will scan the information broadcast by multiple devices. Therefore, the first device usually needs to first determine the information broadcast by the first device (that is, the aforementioned first information) from all the information it scans, and then further use the first key to decrypt the first information broadcast by the first device to obtain the pairing code. Based on this, RPA and IRK are introduced, and the second device uses RPA to broadcast the first information. After the first device scans the information, the first device can use the IRK it determines to parse the RPA of the information it scanned. When the parsing is successful, it is confirmed that the information is the first information sent by the second device.

[0094] Furthermore, in some embodiments, the "relationship between RPA and IRK" may be: RPA is an address generated using random numbers Prand and IRK. Specifically, an RPA may include a 24-bit Prand and a 24-bit HASH, and the HASH is a function of IRK and Prand, HASH=ah(IRK, Prand). Based on this, the above-mentioned method of "the first device using IRK to parse RPA" may include: after the first device receives the broadcast information, it may first parse the RPA corresponding to the information, and extract HASH and Prand from the RPA. Afterwards, the first device will use the IRK determined in step 301 in combination with the extracted Prand to generate a local HASH value, and compare the local HASH value with the HASH value extracted from the RPA to see if they are consistent. When they are consistent, the parsing is determined to be successful, indicating that the information was sent by the first device. When they are inconsistent, the parsing is determined to have failed, indicating that the information was not sent by the first device.

[0095] It can be seen from this that in the embodiment of the present disclosure, by introducing RPA and IRK, the first device can confirm which information is the first information broadcast by the second device, thereby realizing the discovery of the second device by the first device and ensuring that the first device can successfully establish a connection with the second device. At the same time, after the introduction of RPA and IRK, for devices that do not know the IRK of the second device, it is impossible to parse the first information broadcast by the second device, and thus it is impossible to know the pairing code included in the first information. Under the dual protection of IRK and the aforementioned first key, the pairing code in the first information broadcast by the first device can be prevented from being leaked, thereby ensuring the security of the communication connection.

[0096] Optionally, in some embodiments, the method for the first device to determine the IRK may include at least one of the following:

[0097] Receive the IRK sent by the server;

[0098] An IRK pre-configured (eg, factory configured or written in other trusted ways) in the first device is determined.

[0099] Step 302: Receive first information broadcasted by the second device using the RPA based on the IRK.

[0100] Optionally, in some embodiments, the first device may receive the first information broadcast by the second device using RPA based on the IRK determined in the above step 301, and for a detailed introduction to this part, please refer to the description of the above embodiment.

[0101] In summary, in the communication connection method provided by the embodiment of the present disclosure, the second device will use RPA to broadcast the first information, and the first device will determine the IPK of the second device. At the same time, the first device will use the IPK of the second device to receive the first information broadcast by the second device using RPA. Thus, by introducing RPA and IRK, the first device can discover the second device, ensuring that the first device can successfully establish a connection with the second device. At the same time, after the introduction of RPA and IRK, for devices that do not know the IRK of the second device, it is impossible to parse the first information broadcast by the second device, and thus it is impossible to know the pairing code included in the first information. Under the dual protection of IRK and the first key, the pairing code in the first information broadcast by the first device can be prevented from being leaked, thereby ensuring the security of the communication connection.

[0102] FIG4a is a flow chart of a communication connection method provided by an embodiment of the present disclosure. The method is executed by a second device. As shown in FIG4a , the communication connection method may include the following steps:

[0103] Step 401a: broadcast a first message, where the first message includes a pairing code.

[0104] Optionally, the pairing code is used to connect to the second device. For example, the pairing code is used to connect to the second device via Bluetooth and / or NFC.

[0105] For a detailed description of step 401a, please refer to the above embodiment description.

[0106] Step 402a: In response to determining that the first device requests to connect to the second device, verify the first device.

[0107] Optionally, in some embodiments, when the second device receives the connection establishment request including the pairing code sent by the first device, it is determined that the first device requests to connect to the second device.

[0108] Optionally, in some embodiments, the method for the second device to verify the first device may include:

[0109] Verify whether the pairing code in the connection establishment request is consistent with the pairing code stored in the second device (such as the pairing code locally stored in the second device); when the pairing code in the connection establishment request is consistent with the pairing code stored in the second device, determine that the verification is successful, and establish a communication connection with the first device to achieve communication between devices; when the pairing code in the connection establishment request is inconsistent with the pairing code stored in the second device, determine that the verification is unsuccessful, and do not establish a communication connection with the first device.

[0110] In summary, in the communication connection method provided by the embodiment of the present disclosure, the second device will broadcast the first information, which is: information obtained by encrypting the pairing code using the first key; the pairing code is used to connect to the second device; and, in response to the second device determining that the first device requests to connect to the second device, the second device will verify the first device, and when the verification is successful, it will establish a communication connection with the first device. It can be seen that the communication connection method of the embodiment of the present disclosure is achieved by the interaction between the first device and the second device, without the need for user intervention. Therefore, the present disclosure provides a method for seamless connection between devices, which is more efficient, more convenient to operate, and can also improve user experience.

[0114] Step 402b: In response to determining that the first device requests to connect to the second device, verify the first device.

[0115] For a detailed description of steps 401b-402b, please refer to the above embodiment description.

[0116] In summary, in the communication connection method provided by the embodiment of the present disclosure, the second device will broadcast the first information, and the first information includes a pairing code; the pairing code is used to connect to the second device; and, in response to the second device determining that the first device requests to connect to the second device, the second device will verify the first device, and when the verification is passed, it will establish a communication connection with the first device. It can be seen that the communication connection method of the embodiment of the present disclosure is implemented by the interaction between the first device and the second device, without the need for user intervention. The present disclosure provides a method for seamless connection between devices, which is highly efficient, convenient to operate, and can also improve user experience. In addition, in the communication connection method of the embodiment of the present disclosure, the first device encrypts the pairing code to obtain the first information and then broadcasts the first information, thereby avoiding the pairing code from being directly exposed to the communication environment, preventing the pairing code from being maliciously intercepted by other devices, and improving the security of the communication connection.

[0117] FIG5 is a flow chart of a communication connection method provided by an embodiment of the present disclosure. The method is executed by a second device. As shown in FIG5 , the communication connection method may include the following steps:

[0118] Step 501: Use RPA to broadcast first information.

[0119] For a detailed description of step 501 , please refer to the above embodiment description.

[0120] In summary, in the communication connection method provided by the embodiment of the present disclosure, the second device will use RPA to broadcast the first information, and the first device will determine the IPK of the second device. At the same time, the first device will use the IPK of the second device to receive the first information broadcast by the second device using RPA. Thus, by introducing RPA and IRK, the first device can discover the second device, ensuring that the first device can successfully establish a connection with the second device. At the same time, after the introduction of RPA and IRK, for devices that do not know the IRK of the second device, it is impossible to parse the first information broadcast by the second device, and thus it is impossible to know the pairing code included in the first information. Under the dual protection of IRK and the first key, the pairing code in the first information broadcast by the first device can be prevented from being leaked, thereby ensuring the security of the communication connection.

[0121] FIG6 is a flow chart of a communication connection method provided by an embodiment of the present disclosure. The method is executed by a second device. As shown in FIG6 , the communication connection method may include the following steps:

[0122] Step 601: Update the pairing code stored in the second device.

[0123] Since the pairing code stored by the second device may be leaked, this could affect the security of the communication connection. Therefore, in some embodiments, the second device may update its stored pairing code in real time or periodically (e.g., every 30 seconds). Furthermore, the first information broadcast by the second device may be information obtained by encrypting the latest pairing code stored by the second device using the first key.

[0124] It can be seen from this that in the embodiment of the present disclosure, the second device will update the pairing code, and the second device will encrypt the latest pairing code and broadcast it so that other devices (such as the first device) can know the latest pairing code and use the latest pairing code to request to establish a communication connection with the second device. In other words, in the embodiment of the present disclosure, the first device always uses the latest pairing code to establish a communication connection with the second device. The pairing code that has been updated in the past is invalid and cannot be used to establish a communication connection with the second device. Therefore, even if the pairing code stored by the second device is leaked at a certain point in time, as the pairing code stored by the second device is updated, the leaked pairing code will not affect the security of the communication connection.

[0125] To summarize, in the communication connection method provided by the embodiments of the present disclosure, the second device will update its stored pairing code and always use the latest pairing code to establish a communication connection with the first device. The pairing code that has been updated historically is invalid and cannot be used to establish a communication connection with the first device. Therefore, even if the pairing code stored by the second device is leaked at a certain point in time, as the pairing code stored by the second device is updated, the leaked pairing code will not affect the security of the communication connection, thereby solving the technical problem of "the security of the communication connection is affected due to the leakage of the pairing code".

[0126] FIG7 is a flow chart of a communication connection method provided by an embodiment of the present disclosure. The method is executed by the second device. As shown in FIG7 , the communication connection method may include the following steps:

[0127] Step 701: Verify whether the pairing code in the connection establishment request is consistent with the pairing code obtained by each update of the second device within a first preset time period before the current moment.

[0128] Step 702: When the pairing code in the connection establishment request is consistent with the pairing code obtained by any update of the second device within the first preset time period before the current moment, it is determined that the verification is successful, and a communication connection is established with the first device.

[0129] Optionally, in some embodiments, because the pairing code stored by the second device may be updated, the following situation may occur: for example, the second device broadcasts a first message encrypted by a first key at a first time point, where the most recent pairing code stored by the second device at the first time point is the first pairing code. The pairing code included in the first message broadcast at the first time point is the first pairing code. Furthermore, after receiving the first message, the second device decrypts the first message using the first key to obtain the first pairing code, and the first device sends a connection establishment request to the second device, where the connection establishment request includes the first pairing code. However, before receiving the connection establishment request from the first device, the second device updates its pairing code. In this case, the most recent pairing code is the second pairing code, no longer the first pairing code. When the second device receives the connection establishment request from the first device, the communication connection may fail to be established because the first pairing code included in the connection establishment request is inconsistent with the second device's most recent second pairing code.

[0130] Based on this, in some embodiments, to prevent the above situation from occurring, the second device may verify the first device by verifying whether the pairing code in the connection establishment request is consistent with the pairing code obtained by the second device at each update within a first preset time period before the current moment. If the pairing code in the connection establishment request is consistent with the pairing code obtained by the second device at any update within the first preset time period before the current moment, the verification is determined to be successful, and a communication connection is established with the first device. Optionally, in some embodiments, the first preset time period is at least greater than the update period of the pairing code by the second device.

[0131] For example, assuming that the update cycle of the pairing code of the second device is: 30s, and the first preset time period is 70s, the method for the second device to verify the first device can, for example, be: verify whether the pairing code in the connection establishment request is consistent with the pairing code obtained by each update of the second device within 70s before the current moment, such as verifying whether the pairing code in the connection establishment request is consistent with the pairing code obtained by the second device in the most recent update, the pairing code obtained in the last update, and the pairing code obtained in the previous update. If the pairing code in the connection establishment request is consistent with any one of the pairing code obtained by the second device in the most recent update, the pairing code obtained in the last update, and the pairing code obtained in the previous update, the verification is determined to be successful.

[0132] In summary, in the communication connection method provided by the embodiments of the present disclosure, the second device verifies whether the pairing code in the connection establishment request sent by the first device is consistent with the pairing code obtained by each update of the second device within a first preset time period before the current moment. When the pairing code in the connection establishment request is consistent with the pairing code obtained by any update of the second device within the first preset time period before the current moment, the verification is determined to be successful, and a communication connection is established with the first device. This avoids the situation where, after the first device receives the first information broadcast by the second device, the second device updates its stored pairing code, resulting in the pairing code included in the connection establishment request sent by the first device being inconsistent with the latest pairing code stored by the second device, causing the communication connection to fail. This ensures that the first device and the second device can successfully establish a communication connection.

[0133] FIG8 is a flow chart of a communication connection method provided by an embodiment of the present disclosure. The method is executed by the second device. As shown in FIG8 , the communication connection method may include the following steps:

[0134] Step 801: In response to receiving a connection establishment request sent by a first device, stop updating the pairing code stored in the second device within a second preset time period after the current moment.

[0135] Optionally, in some embodiments, after receiving a connection establishment request from the first device, the second device may need a period of time to parse the connection establishment request to obtain the pairing code included in the connection establishment request. During this period of time, the second device may likely update its stored pairing code, causing the pairing code included in the connection establishment request to be inconsistent with the second device's current latest pairing code, thereby causing the first device and the second device to fail to establish a communication connection. Therefore, in some embodiments, after receiving a connection establishment request from the first device, the second device may stop updating its stored pairing code for a second preset period of time after the current moment. This second preset period of time may be at least longer than the time it takes the second device to parse the connection establishment request. This avoids the situation where, during the period of time the second device parses the connection establishment request, the pairing code included in the connection establishment request is inconsistent with the second device's current latest pairing code due to an update to its stored pairing code, thereby causing the first device and the second device to fail to establish a communication connection. This ensures that the first device and the second device can successfully establish a communication connection.

[0136] In summary, in the communication connection method provided in the embodiments of the present disclosure, in response to a second device receiving a connection establishment request sent by a first device, the second device stops updating the pairing code stored on the second device within a second preset time period after the current moment. This avoids the situation where, during the time period when the second device is parsing the connection establishment request, the pairing code stored on the second device is updated, resulting in an inconsistency between the pairing code included in the connection establishment request and the second device's latest pairing code at the current moment, thereby causing the communication connection between the first and second devices to fail. This ensures that the first and second devices can successfully establish a communication connection.
