In addition, in this embodiment, the number of the bluetooth devices 103 is not limited, and may be one or more. In fig. 1, a plurality of bluetooth devices 103 operating in the broadcast mode are illustrated as an example.

The bluetooth device 103 and the bluetooth gateway 101 may be from the same manufacturer or from different manufacturers. In general, the bluetooth device 103 and the bluetooth gateway 101 are devices provided by different manufacturers. Whether or not the bluetooth device 103 is from the same vendor as the bluetooth gateway 101, the bluetooth gateway 101 may receive data that is broadcast out of any bluetooth device 103 that is within its coverage area. Further, the bluetooth gateway 101 reports the received broadcast data from the bluetooth device 103 to the server device 102, so that the server device 102 provides data storage service or data processing service for the bluetooth device 103.

In this embodiment, the number of the server devices 102 is not limited, and may be one or more. In addition, the device form of the server device 102 is not limited. For example, the server device 102 may be a conventional server, a cloud host, a virtual center or a server array, and the like. The server device 102 mainly includes a processor, a hard disk, a memory, a system bus, and the like, and is similar to a general computer architecture. Fig. 1 illustrates a server device 102 as an example.

In the network system shown in fig. 1, the bluetooth device 103 operating in the broadcast mode may broadcast data to the outside, but cannot receive the data; if the bluetooth device 103 is in the coverage of the bluetooth gateway 101, the data broadcasted outside by the bluetooth device 103 can be received by the bluetooth gateway 101; after receiving the data broadcasted outside by the bluetooth device 103, the bluetooth gateway 101 may report the data to the server device 102; the server device 102 may save the received data. Further optionally, the server device 102 may perform various processing on the data according to application requirements, such as cleaning, verification, text recognition or format conversion. Further optionally, the server device 102 may also provide services related to the received data to the outside, such as query services, download services, and the like. The server device 102 and the bluetooth gateway 101 may be in wireless communication connection or in wired communication connection, which is not limited to this.

In this embodiment, in order to avoid intercepting and tampering the data broadcasted by the bluetooth device 103 to the outside, and to provide security for the data broadcasted by the bluetooth device 103 to the outside, an encrypted broadcast scheme is provided for the bluetooth device 103 operating in the broadcast mode. That is, the same set of encryption and decryption algorithms is run at both ends of the bluetooth device 103 and the server device 102, the bluetooth device 103 and the server device 102 store keys locally, the bluetooth device 103 encrypts data by using a locally preset key and then broadcasts the encrypted data, the server device 102 decrypts the encrypted data by using a locally pre-stored key, the key is only known by the bluetooth device 103 and the server device 102, and the key is not transmitted over the air, so that the probability of data interception and tampering can be reduced, and the security of data in the transmission process can be improved.

The following embodiment will describe in detail a data transmission process among the bluetooth device 103, the bluetooth gateway 101, and the server device 102 in the network system shown in fig. 1 with reference to the interaction flowchart shown in fig. 2 a. As shown in fig. 2a, the data transmission process includes:

21a, the bluetooth device 103 encrypts the data to be transmitted by using a preset encryption algorithm and a preset key to obtain encrypted data.

22a, the Bluetooth device 103 encapsulates the identity of the Bluetooth device and the encrypted data into a data packet.

23a, the bluetooth device 103 works in the broadcast mode, and broadcasts the data packet to the outside.

24a, after receiving the data packet broadcasted outside by the bluetooth device 103, the bluetooth gateway 101 reports the data packet to the server device 102.

If the bluetooth device 103 is located in the coverage area of the bluetooth gateway 101, the bluetooth gateway 101 receives the data packet broadcasted by the bluetooth device 103.

25a, after receiving the data packet reported by the bluetooth gateway 101, the server device 102 determines a key used by the bluetooth device 103 from the locally stored key according to the identity of the bluetooth device 103 carried in the data packet.

26a, the server device 102 decrypts the encrypted data carried in the data packet according to the key used by the bluetooth device 103, so as to obtain decrypted data.

In step 21a, the data to be transmitted is data that needs to be sent to the outside by the bluetooth device 103, and may be some data preset in the bluetooth device 103, or may be data generated by the bluetooth device 103 during the use process. For example, if the bluetooth device 103 is a weight scale, the data to be transmitted may be weight data acquired by the weight scale in the using process; if the Bluetooth device 103 is a body fat scale, the body fat scale refers to body fat data acquired in the using process; if the bluetooth device 103 is an intelligent bracelet, the data to be transmitted may be exercise data collected by the intelligent bracelet in the using process; if the bluetooth device 103 is a medical apparatus, the data to be transmitted may be blood oxygen, blood pressure, and other data acquired by the medical apparatus during the use process, which is not limited herein.

The identity of the bluetooth device 103 may be any information capable of uniquely identifying the bluetooth device 103, such as a name, an ID, a serial number, or a short name of the bluetooth device 103, which is not limited herein. It should be noted that the identification of the bluetooth device 103 may include some functional descriptions related to the bluetooth device 103, other information helpful for identifying the bluetooth device 103, and the like, besides information capable of uniquely identifying the bluetooth device. In an alternative embodiment, the product ID to which the bluetooth device 103 belongs and the MAC address of the bluetooth device 103 may be used as the identity of the bluetooth device 103. The product ID is used to uniquely identify one type of bluetooth device 103, for example, the product ID to which the body fat scale belongs is different from the product ID to which the bluetooth bracelet belongs, and in addition, a plurality of identical bluetooth devices are provided under one product ID, for example, the same series or same generation of body fat scales produced by the same manufacturer correspond to the same product ID. The MAC address is used to uniquely identify a bluetooth device 103.

In this embodiment, the bluetooth device 103 is also preset with a key, but the specific implementation of presetting the key in the bluetooth device 103 is not limited. For example, the key used by the bluetooth device 103 may be configured during initialization of the bluetooth device 103. For another example, the key used by the bluetooth device 103 may be preset in the bluetooth device 103 during factory configuration of the bluetooth device 103. In addition, in this embodiment, the source of the key used by the bluetooth device 103 is also not limited, and may be provided by the server device 102, or may be provided by a third party vendor to which the bluetooth device 103 belongs, for example. If the key is provided by a third party vendor to which the bluetooth device 103 belongs, the third party vendor needs to provide the key to the server device 102 in addition to pre-installing the key in the bluetooth device 103. Similarly, if the key is provided by the server device 102, the key needs to be provided to the third party manufacturer, so that the third party manufacturer can preset the key into the bluetooth device 103.

The following describes a process of presetting a key on the bluetooth device 103 in detail by taking the server device 102 as an example to provide the key in a unified manner.

In an alternative embodiment, the server device 102 provides services such as data storage and/or processing for bluetooth devices of third party vendors, and is responsible for providing keys for bluetooth devices of third party vendors using the services. For a third party manufacturer, if it is desired that the bluetooth device 103 provided by the third party manufacturer can use the service provided by the server device 102, a service binding request may be sent to the server device 102, and a product ID requesting service binding is carried in the service binding request to indicate which type of bluetooth device applies for service binding. The server device 102 may receive a service binding request sent by a third party manufacturer, and allocate at least one key to the product ID from locally stored keys according to the service binding request; and further, issuing at least one key to a third party manufacturer. For the third party manufacturer, after receiving at least one key under the server device 102, the at least one key may be configured into at least one bluetooth device 103 under the product ID, and one key may be configured into one bluetooth device 103, so as to achieve one secret. Further, for the server device 102, it is necessary to acquire a corresponding relationship between the identity of at least one bluetooth device 103 and at least one key, and locally store the corresponding relationship between the identity of at least one bluetooth device 103 and the at least one key, so as to decrypt the encrypted data from the bluetooth device 103 using the corresponding key.

In the above embodiment, the number of at least one key is not limited. Optionally, the third party manufacturer may carry the number of the bluetooth devices requesting the service binding in the service binding request, where the number is the number of the at least one secret key. Alternatively, the server device 102 may also preset the number of bluetooth devices allowed to be bound in each service binding request, where the number is the number of at least one key. Alternatively, the server device 102 may flexibly determine the number of the at least one secret key according to the number of the bluetooth devices that can be currently bound, that is, the number of the bluetooth devices that are allowed to be bound by the third party vendor at this time.

In the above embodiment, the manner in which the server device 102 obtains the correspondence between the at least one bluetooth device 103 and the at least one secret key is not limited. Two embodiments are given below:

embodiment 1: in this embodiment, the server device 102 may not only provide the key for the third party manufacturer, but also apply for the MAC address for the locally stored key, and establish the corresponding relationship between the MAC address and the key. Wherein one key corresponds to one MAC address. Based on this, the server device 102 issues the MAC address corresponding to the at least one secret key to the third party manufacturer, in addition to issuing the at least one secret key to the third party manufacturer. For a third party manufacturer, the MAC address provided by the server device 102 can be directly used without applying for the MAC address for its bluetooth device, and a key and its corresponding MAC address can be configured into a bluetooth device under the product ID. In this embodiment, the server device 102 may further establish and store a correspondence between the product ID, the at least one key, and the MAC address of the at least one bluetooth device based on the correspondence between the MAC address and the key. The MAC address and the product ID of the bluetooth device can be used as the identification of the bluetooth device.

Embodiment 2: in this embodiment, the third party manufacturer may apply for the MAC address for the generated bluetooth device 103 itself, and configure the applied MAC address to the bluetooth device 103. In addition, after receiving at least one key assigned by the server device 102 for the product ID, each key may be configured into one bluetooth device. The bluetooth device configured with the key has its own MAC address. After configuring the keys issued by the server device 102 to the bluetooth devices, the third party manufacturer may report the MAC address of the bluetooth device where each key is located to the server device 102, so that the server device 102 may obtain the MAC address corresponding to each key, and further locally establish and store the corresponding relationship between the product ID, each key, and the MAC address. The MAC address and the product ID of the bluetooth device can be used as the identification of the bluetooth device.

No matter which preset key implementation is adopted, the server device 102 and the bluetooth device 103 may have a common key. Alternatively, the server device 102 may store the key in a separate storage system, or in a local cache. The bluetooth device 103 may burn the key into a Non-Volatile Memory (NVM) of the bluetooth device 103, and encrypt the data to be transmitted by using the key, thereby ensuring the security of data transmission. The NVM includes, but is not limited to, Flash memory (Flash memory), Read-only memory (ROM), and the like.

In the present embodiment, the encryption algorithm used is not limited. For example, if the bluetooth device 103 is highly computing, a relatively complex software encryption algorithm may be used, such as a symmetric encryption algorithm. Preferably, considering that the bluetooth device 103 has limited computing power and hardware resources, a relatively simple hardware encryption algorithm, such as Exclusive OR (XOR) operation, Exclusive NOR (XNOR) operation, etc., may be used.

In the embodiment of the present application, a specific implementation manner of encrypting data to be transmitted to obtain encrypted data is not limited to using a preset encryption algorithm and a preset key. In an optional embodiment, a pre-made encryption algorithm may be adopted, and the data to be transmitted is directly encrypted by using the key, so as to obtain encrypted data. In another optional embodiment, in the process of encrypting the data to be transmitted by using a preset encryption algorithm and a preset key, a random number may be introduced, and the random number may be carried in a data packet and reported to the server device, and if the server device receives a repeated random number, a discard policy may be executed to discard the data packet, thereby avoiding a replay attack. The random number may be a pseudo random number or a true random number. In an alternative embodiment, true random numbers are used in the encryption of the data to be transmitted. Specifically, a true random number a can be generated according to a physical variable generated in the running process of the bluetooth device; and encrypting the true random number A and the data to be transmitted by adopting a preset encryption algorithm and a key to obtain encrypted data.

In the present embodiment, the physical variable on which the true random number a is generated is not limited, and may be, for example, hardware noise, a voltage value, or a current value generated during the operation of the bluetooth device 103. Specifically, the true random number a may be generated according to a voltage value or a current value of a Micro Control Unit (MCU) of the bluetooth device 103. The algorithm for generating the true random number a according to the physical variable is not limited, and can adopt but not limited to: acquiring an instantaneous value of a physical variable by using an Analog-to-digital converter (ADC) as a true random number a, for example, when the physical variable is a current or a voltage, the true random number a is an instantaneous current value or a voltage value acquired by the ADC; and manually moving the mouse to reach a certain length, and inputting the motion track of the mouse within the length as an independent variable into a key generation tool to obtain a true random number A, and the like.

Further, after the true random number a and the data to be transmitted are encrypted by using a preset encryption algorithm and a key to obtain encrypted data, the identity of the bluetooth device 103, the true random number a, and the encrypted data may be encapsulated into a data packet. Further, in step 23a, the data packet is broadcast.

For step 23a, the embodiment does not limit the specific implementation of the outbound broadcast packet. For example, the bluetooth device 103 may broadcast the data packet once to the outside in a conventional communication manner. For another example, considering that the bluetooth device operates in a broadcast mode, and has no interactivity, that is, only the data packet can be broadcasted to the outside, but the data packet cannot be received from other devices, in order to solve the problem of non-interactive broadcast data loss, optionally, a certain broadcast time can be set, and then the same data packet is broadcasted to the outside for multiple times within the set broadcast time, so as to improve the transmission reliability; or, a certain number of broadcast times is set, and the same data packet is broadcast for multiple times according to the set number of broadcast times, so that the transmission reliability is improved. The set broadcast time may be, but is not limited to: 1 second, 3 seconds, 5 seconds, etc.; the set number of broadcasts may be, but is not limited to: 5 times, 10 times, 50 times, etc.

In step 24a, the bluetooth gateway 101 may perform signal scanning within its coverage area; if the data packet broadcasted by the bluetooth device 103 is scanned, the data packet is reported to the server device 102.

Alternatively, the bluetooth gateway 101 may automatically perform signal scanning according to the set signal scanning policy after being powered on. For example, the signal scanning policy specifies a period of signal scanning, and the bluetooth gateway 101 may periodically perform signal scanning according to the period after being powered on. For another example, the signal scanning policy specifies a time point for performing signal scanning and a time duration of each signal scanning, and the bluetooth gateway 101 may automatically start performing signal scanning when the set time point arrives after the bluetooth gateway is powered on, and end signal scanning when the specified signal scanning time duration arrives.

Alternatively, the first and second electrodes may be,

optionally, the user may also send a signal scanning instruction to the bluetooth gateway 101 according to the scanning requirement. The bluetooth gateway 101 may respond to a signal scanning command issued by a user to scan signals within its coverage area. The method can control the Bluetooth gateway 101 to scan signals according to the requirement, and is beneficial to saving the resources of the Bluetooth gateway 101. Wherein, the user can send a signal scanning instruction to the bluetooth gateway 101 by adopting, but not limited to, the following modes:

in the method 1, the bluetooth gateway 101 has a voice recognition function. The user may send a signal scanning command in a voice manner to instruct the bluetooth gateway 101 to perform signal scanning.

In the mode 2, the App of the bluetooth gateway 101 is installed on the terminal device of the user, and based on this, the user can send a signal scanning instruction to the bluetooth gateway 101 through the App of the bluetooth gateway 101 to instruct the bluetooth gateway 101 to perform signal scanning.

In the mode 3, the bluetooth gateway 101 is provided with an electronic screen, and a user can input a signal scanning instruction to the bluetooth gateway 101 through the electronic screen of the bluetooth gateway 101 to instruct the bluetooth gateway 101 to perform signal scanning. For example, a control page of the bluetooth gateway 101 may be displayed on the electronic screen, and a scanning control is provided on the control page, and a user may send a signal scanning instruction to the bluetooth gateway 101 by triggering the scanning control.

In step 25a, after receiving the data packet reported by the bluetooth gateway 101, the server device 102 may analyze the identity and the encrypted data of the bluetooth device 103 from the data packet; further, the key used by the bluetooth device 103 is determined from the locally stored key according to the correspondence between the identity of the bluetooth device 103 and the key. Further, in step 26a, the encrypted data carried in the packet is decrypted based on the key used by the bluetooth device 103, and the decrypted data is obtained. After obtaining the decrypted data, the server device 102 may further perform other processing such as storing the decrypted data, which is not limited to this.

In an alternative embodiment, the server device 102, before determining the key used by the bluetooth device 103 from the locally stored keys, is further configured to: according to the identity of the Bluetooth device 103, performing identity verification on the Bluetooth device 103; if the bluetooth device 103 passes the identity verification, the key used by the bluetooth device 103 is determined from the locally stored keys according to the identity of the bluetooth device 103.

The specific implementation of the identity verification of the bluetooth device 103 is not limited. In an alternative embodiment, the verification may be performed locally at the server device 102. Specifically, if the identification of the bluetooth device 103 includes a product ID and a MAC address, the server device 102 may determine whether the product ID and the MAC address of the bluetooth device 103 are legal according to a legal product ID and a legal MAC address stored locally in advance; if the two are legal, determining that the Bluetooth equipment passes identity verification; otherwise, determining that the Bluetooth equipment does not pass the identity verification. In another optional embodiment, the server device 102 may send the identity of the bluetooth device 103 to a third party vendor server, and the third party vendor server performs identity verification on the bluetooth device. Under the condition that the identity identifier of the Bluetooth device comprises a product ID and an MAC address, a server of a third party manufacturer can inquire whether the product ID and the MAC address of the Bluetooth device 103 are legal or not according to a local legal product ID and a legal MAC address; if the two are legal, determining that the Bluetooth equipment passes identity verification; otherwise, determining that the Bluetooth equipment does not pass the identity verification.

In the above embodiment, the bluetooth device 103 and the server device 102 respectively store the keys locally, the bluetooth device 103 encrypts the data by using the locally preset key and then broadcasts the encrypted data, the server device 102 decrypts the encrypted data by using the locally preset key, the keys are only known by the bluetooth device 103 and the server device 102, and the keys are not transmitted over the air, which can reduce the probability of data interception and tampering, and is beneficial to improving the security of the data in the transmission process.

In some optional embodiments of the present application, in view of security considerations on the server device 102 and the bluetooth gateway 101, in order to prevent malicious visitors such as hackers from attacking the network system by forging data packets of the bluetooth device 103, a distribution network process is further provided for the bluetooth device 103 operating in the broadcast mode, discovery and binding of the bluetooth device can be performed through the distribution network process, the server device and the bluetooth gateway only need to process data packets from the bound bluetooth device (or referred to as a distributed bluetooth device), and do not need to process data packets from other unbound bluetooth devices (also referred to as non-distributed bluetooth devices), so that probability of malicious attack on the server device or the network system can be reduced, and security of the system can be improved.

With reference to the interaction flowchart shown in fig. 2b, a process of performing a network distribution between the bluetooth gateway 101, the bluetooth device 103, and the server device 102 is described below, where the network distribution process includes the following steps:

21b, the Bluetooth device 103 generates a network distribution package according to the identity of the Bluetooth device.

22b, the bluetooth device 103 broadcasts the distribution network packet to the outside to initiate the distribution network flow to the server device 102.

23b, after receiving the distribution network packet broadcasted by the bluetooth device 103, the bluetooth gateway 101 reports the distribution network packet to the server device 102.

If the bluetooth device 103 is located in the coverage area of the bluetooth gateway 101, the bluetooth gateway 101 receives the network distribution packet broadcasted by the bluetooth device 103 to the outside.

24b, after receiving the distribution network packet reported by the bluetooth gateway 101, the server device 102 performs distribution network verification on the bluetooth device 103 according to the identity of the bluetooth device 103 carried in the distribution network packet.

25b, under the condition of passing the distribution network verification, the server side device 102 returns a message that the Bluetooth device 103 passes the distribution network verification to the Bluetooth gateway 101.

26b, the bluetooth gateway 101 adds the identity of the bluetooth device to the list of the distributed devices according to the message which is returned by the server device 102 and passes the distribution network verification.

After the bluetooth gateway 101 adds the identity of the bluetooth device to the list of the configured devices, the bluetooth device is changed from the device that is not configured to the device that is configured. The distributed network equipment is legal and safe for the Bluetooth gateway 101 and the server side equipment 102.

Further, after the distribution network process is completed, data transmission may also be performed between the bluetooth gateway 101 and the bluetooth device 103 and between the bluetooth gateway and the server device 102, where the data transmission process may be an encrypted data transmission process or a plaintext data transmission process. As shown in fig. 3, the process of performing encrypted data transmission between the bluetooth gateway 101 and the bluetooth device 103 and the server device 102 includes:

27b, the bluetooth device 103 encrypts the data to be transmitted by using a preset encryption algorithm and a preset key to obtain encrypted data.

28b, the Bluetooth device 103 encapsulates the identity of the Bluetooth device and the encrypted data into a data packet.

29b, the bluetooth device 103 works in the broadcast mode to broadcast the data packet to the outside.

30b, after receiving the data packet broadcasted by the bluetooth device 103, the bluetooth gateway 101 determines whether the bluetooth device 103 is a device already in the network according to the identity of the bluetooth device 103.

31b, if the bluetooth device 103 is a configured network device, the bluetooth gateway 101 reports the data packet to the server device 102.

33b, the server device 102 decrypts the encrypted data carried in the data packet according to the key used by the bluetooth device 103, so as to obtain decrypted data.

In step 21b, the specific implementation of generating the network distribution package according to the identity of the bluetooth device 103 is not limited. In an alternative embodiment, the product ID and the MAC address in the ID of the bluetooth device 103 may be directly encapsulated into a network packet.

In another optional embodiment, in the process of generating the distribution network packet according to the identity of the bluetooth device 103, a random number may be introduced, and the random number may be carried in the distribution network packet and reported to the server device, and if the server device receives a repeated random number, a discard policy may be executed to discard the distribution network packet, thereby avoiding a replay attack. The random number may be a pseudo random number or a true random number. In an alternative embodiment, a true random number is used in generating the networking packet based on the identity of the bluetooth device 103. Specifically, the true random number B may be generated according to a physical variable generated by the bluetooth device 103 during operation; encrypting the true random number B by adopting a preset encryption algorithm and a key to obtain an encrypted value; and packaging the identity identifier, the encryption value and the true random number B of the Bluetooth device 103 into a network distribution package. In this embodiment, the physical variables on which the true random number B depends and the algorithm for generating the true random number B according to the physical variables are not limited, and specific reference may be made to the specific implementation of generating the true random number a, which is not described herein again. Further, in step 22b, the distribution network packet is broadcast.

For step 22b, the embodiment does not limit the specific implementation of the outbound broadcast network packet. For example, the bluetooth device 103 may broadcast the data packet once to the outside in a conventional communication manner. For another example, considering that the bluetooth device operates in a broadcast mode and has no interactivity, that is, only an external broadcast data packet is available, but data sent by other devices cannot be received, in order to solve the problem of non-interactive broadcast data loss, optionally, a certain broadcast time may be set, and then the same data packet is externally broadcast for multiple times within the set broadcast time, so as to improve transmission reliability; or, a certain number of broadcast times is set, and the same data packet is broadcast for multiple times according to the set number of broadcast times, so that the transmission reliability is improved. The set broadcast time may be, but is not limited to: 1 second, 3 seconds, 5 seconds, etc.; the set number of broadcasts may be, but is not limited to: 5 times, 10 times, 50 times, etc.

In step 23b, the bluetooth gateway 101 may perform signal scanning within its coverage area. For details of the information scanning performed by the bluetooth gateway 101, please refer to the foregoing embodiments, which are not described herein again.

In step 23b, before reporting the distribution network packet to the server device 102, the bluetooth gateway 101 is further configured to: reporting the product ID in the identity of the Bluetooth device to the server device, so that the server device 102 can perform product validity check on the Bluetooth device; receiving device detail information of the Bluetooth device 103 returned by the server device 102 after the Bluetooth device 103 passes the product validity check; the device detail information of the Bluetooth device 103 is displayed so that a user can determine whether to initiate a distribution network process aiming at the Bluetooth device 103; and responding to an instruction sent by the user to determine that the Bluetooth device 103 initiates a distribution network process, and reporting the distribution network packet to the server device 102.

Correspondingly, in step 24b, before receiving the distribution network packet reported by the bluetooth gateway 101, the server device 102 is further configured to: receiving a product ID in the identity of the Bluetooth device 103 reported by the Bluetooth gateway 101; according to the product ID of the Bluetooth device 103, checking the product validity of the Bluetooth device 103; and when the Bluetooth device passes the product validity check, returning the device detail information of the Bluetooth device 103 to the Bluetooth gateway 101, so that the user can determine whether to initiate a distribution network process for the Bluetooth device 103.

The product validity check is performed on the bluetooth device 103, that is, whether the device class to which the bluetooth device 103 belongs to a legal device class is determined, for example, whether the bluetooth device 103 belongs to a certain bluetooth device that has signed a contract with the server device 102 is determined. The server device 102 may maintain the product ID corresponding to the legal device type, and based on this, the product ID corresponding to the bluetooth device 103 may be matched with the legal product ID; if the product ID corresponding to the Bluetooth device 103 is matched in the legal product IDs, determining that the Bluetooth device 103 passes the product validity check; otherwise, it is determined that the bluetooth device 103 fails the product validity check. Further, in the case that the bluetooth device 103 passes the product validity check, the server device 102 returns the device detail information of the bluetooth device 103 to the bluetooth gateway 101. The device detail information of the bluetooth device 103 includes, but is not limited to: type, manufacturer, profile of the bluetooth device 103, etc. When determining that the distribution network process needs to be initiated to the bluetooth device 103 according to the device detail information of the bluetooth device 103, the user may send an instruction for determining that the distribution network process is initiated to the bluetooth device 103 to the bluetooth gateway 101 in the following manners:

in the method 1, the bluetooth gateway 101 has a voice recognition function. The user may send an instruction to determine to initiate a distribution network procedure to the bluetooth device 103 in a voice manner, and instruct the bluetooth gateway 101 to report the distribution network packet to the server device 102.

In the mode 2, the App of the bluetooth gateway 101 is installed on the terminal device of the user, and based on this, the user can send an instruction for determining to initiate a distribution network process to the bluetooth device 103 to the bluetooth gateway 101 through the App of the bluetooth gateway 101, and instruct the bluetooth gateway 101 to report a distribution network packet to the server device 102.

In the mode 3, the bluetooth gateway 101 is provided with an electronic screen, and a user can input an instruction for determining that a distribution network process is initiated for the bluetooth device 103 to the bluetooth gateway 101 through the electronic screen of the bluetooth gateway 101, and instruct the bluetooth gateway 101 to report a distribution network packet to the server device 102. For example, a control page of the bluetooth gateway 101 may be displayed on the electronic screen, and a control is provided on the control page, and by triggering the control, the user may send an instruction to the bluetooth gateway 101 to determine that a distribution network procedure is initiated for the bluetooth device 103, and instruct the bluetooth gateway 101 to report the distribution network packet to the server device 102.

Further optionally, if the true random number is used when the distribution network packet is generated in step 21B, in step 24B, the server device 102 may analyze the identity of the bluetooth device 103, the true random number B, and the first encryption value corresponding to the true random number B from the distribution network packet. The first encryption value is obtained by encrypting the true random number B by the bluetooth device 103 according to a locally preset key. Based on this, when the server device 102 performs distribution network verification on the bluetooth device 103 according to the identity of the bluetooth device, it is specifically configured to: according to the identity of the Bluetooth device, the identity of the Bluetooth device 103 is verified; when the identity verification is passed, determining a key used by the Bluetooth device 103 from locally stored keys according to the identity of the Bluetooth device; encrypting the true random number B according to a secret key used by the Bluetooth device 103 to obtain a second encrypted value; and if the second encryption value is the same as the first encryption value, determining that the Bluetooth device 103 passes the distribution network verification. Otherwise, if the second encryption value is different from the first encryption value, it is determined that the bluetooth device 103 fails to pass the distribution network verification.

The identity check is the same as that in the foregoing embodiment, and specific contents may be referred to the foregoing embodiment, which is not described herein again.

After the bluetooth device 103 passes the distribution network verification, in step 25b, the server device 102 returns a message that the bluetooth device 103 passes the distribution network verification to the bluetooth gateway 101. Further, in step 26b, the bluetooth gateway 101 adds the identity of the bluetooth device to the list of the distributed devices, and completes the process of distributing the network to the bluetooth device 103.

After the distribution network, the process of encrypted data transmission between the bluetooth gateway 101, the bluetooth device 103 and the server device 102, i.e. steps 27b-33b, is the same as the embodiment shown in fig. 2a and is not described herein again.

The following takes the application of the broadcast bluetooth technology in a home environment as an example, and exemplifies the technical solution of the embodiment of the present application. As shown in fig. 2c, in a home environment, there are bluetooth devices 103 such as bluetooth scales, bluetooth bracelets, bluetooth handsets, etc., which operate in a broadcast mode. In addition, in the home environment, there is a smart speaker, which uses bluetooth technology, and can receive bluetooth broadcast data (such as data packets and network distribution packets) within its coverage area and upload the data to the server device 102, and the smart speaker can be used as a bluetooth gateway 101 in the home environment. In fig. 2c, the server device 102 is illustrated as a cloud server. The following takes body fat as an example, and an exemplary description is made with reference to the distribution network and data transmission process of body fat as shown in fig. 2 d.

The body fat scale is a measuring device that can measure a fat rate, moisture, bone mass, and the like, in addition to the body weight of a user. In the embodiment of the application, the body fat scale is internally provided with the Bluetooth chip, the hardware resource of the Bluetooth chip is limited, for example, the Bluetooth chip adopts an inner core of a 51-chip microcomputer, the main frequency is 8-16M, the RAM is generally 128 bytes-256 bytes, and the ROM is 4-8K; in view of this, after the measurement is completed, the measured result data needs to be transmitted to the cloud server for storage, so as to prevent the data coverage from being lost. In order to ensure the security of the cloud server, a body fat scale needs to be distributed first, and a distribution process is shown in fig. 2d and includes the following steps:

21d, generating a network distribution packet by the body fat scale according to the identity of the body fat scale and the true random number C, wherein the identity of the body fat scale comprises the ID of the body fat scale and the MAC address of the body fat scale.

22d, the body fat scale works in a broadcasting mode to broadcast the distribution network package, and if the body fat scale is located in the coverage range of the intelligent sound, the intelligent sound can receive the distribution network package of the body fat scale outside broadcasting.

And 23d, analyzing the network distribution package by the intelligent sound equipment, and reporting the ID of the body fat scale in the identity of the body fat scale to the cloud server.

And 24d, the cloud server judges the ID of the body fat scale and carries out validity check.

And 25d, after the cloud server judges that the validity is verified, sending the detailed information of the body fat scale to the intelligent sound box.

26d, the intelligent sound box displays the detailed information of the body fat scale and inquires whether a user initiates a distribution network process aiming at the body fat scale.

27d, the intelligent sound responds to an instruction sent by the user and used for determining that the body fat scale initiates a distribution network process, and the distribution network package is reported to the cloud server.

28d, after receiving the distribution network packet reported by the intelligent sound equipment, the cloud server analyzes the identity of the body fat scale, the true random number C and the first encryption value corresponding to the true random number C from the distribution network packet.

29d, the cloud server performs identity verification on the body fat scale according to the identity of the body fat scale; and when the identity verification is passed, determining a key used by the body fat scale from the locally stored keys according to the identity of the body fat scale.

30d, the cloud server encrypts the true random number C according to a secret key used by the body fat scale to obtain a second encryption value; and if the second encryption value is the same as the first encryption value, determining that the body fat scale passes the distribution network verification.

31d, under the condition that the body fat scale passes the distribution network verification, the cloud server returns a message that the body fat scale passes the distribution network verification to the intelligent sound box.

And 32d, the intelligent sound equipment adds the identity of the Bluetooth equipment to the distributed equipment list according to the information which is returned by the cloud server and passes the distribution network verification.

After the intelligent sound equipment adds the identity of the body fat scale to the list of the distributed equipment, the body fat scale is changed from the equipment which is not distributed to the distributed equipment. For the intelligent sound and the cloud server, the distributed network equipment is legal and safe. Further, after the distribution network flow is completed, data transmission can be performed between the intelligent sound box and the body fat scale and between the intelligent sound box and the cloud server, data leakage is avoided for safe and reliable body fat data transmission, and system data acquired by the body fat scale need to be encrypted and transmitted.

The scheme provides an encryption algorithm aiming at the situation that the Bluetooth device 103 works in a broadcast mode, and the encryption algorithm can be operated on a chip of which the RAM is only 40 bytes. An encryption algorithm preset by the body fat scale is denoted as a _ Encrypt, and a decryption algorithm preset by the cloud server is denoted as a _ Decrypt. The A _ Encrypt algorithm is an encryption algorithm, and the encryption algorithm comprises three arguments, namely a Secret key (Secret), a Random number (Random) and Data to be encrypted (Data); executing the encryption algorithm a _ Encrypt results in encrypted Data (En-Data) and a Data check value (CRC). The CRC is a data transmission error detection function, and is used to ensure the correctness and integrity of data transmission. A _ Decrypt is a decryption algorithm corresponding to the A _ Encrypt encryption algorithm, and the decryption algorithm comprises three arguments of a key (Secret), a Random number (Random) and Data (En-Data) to be decrypted; executing the decryption algorithm a _ Decrypt results in decrypted Data (Data).

As shown in fig. 2e, the data transmission process of reporting the measurement result data to the cloud server by the body fat scale includes the following steps:

33e, body fat scale after measuring the body fat Data, the encryption algorithm a _ Encrypt is used to calculate the encrypted Data (En-Data) and CRC, (En-Data, CRC) ═ a _ Encrypt (preset key (Secret1), true Random number (Random1), body fat scale collected body fat Data).

34e, the body fat scale packages the product ID and the MAC address of the body fat scale, the true Random number (Random1) and the encrypted Data (En-Data) into a Data packet.

Alternatively, a structure of a data packet is shown in fig. 3, and includes: FMASK field, ID field, MAC field, nonce field, data field, and CRC field.

Wherein, the FMASK field: indicating capabilities possessed by the body fat scale, such as the type of broadcast and the version of the protocol, etc. ID field: record the product ID to which the body fat belongs. And MAC field: the MAC address of the body fat name is recorded. Random number field: the true Random number (Random1) added when the body fat data collected by the body fat scale was encrypted in step 33e is recorded. Data field: in step 33e, the encrypted Data (En-Data) obtained by encrypting the body fat Data acquired by the body fat scale by using the encryption algorithm is recorded. CRC field: the CRC value obtained in step 33e is recorded.

35e, the body fat scale works in the broadcasting mode to broadcast data packets to the outside.

36e, if the body fat scale is located in the coverage range of the intelligent sound, the intelligent sound receives a data packet broadcasted outside the body fat scale, and judges whether the body fat scale is the distributed equipment or not according to the identity of the body fat scale.

And 37e, if the body fat is called as the distributed network equipment, the intelligent sound equipment reports the data packet to the cloud server.

38e, after receiving the Data packet reported by the intelligent sound, the cloud server analyzes the product ID, the MAC address, the true Random number (Random1), the encrypted Data (En-Data) and the CRC of the body fat scale from the Data packet.

39e, the cloud server firstly performs CRC check, and if the CRC check is passed, a key (Secret1) used by the body fat scale is determined from the locally stored keys;

40e, the cloud server calculates the decrypted Data (Data) by using the decryption algorithm a _ Decrypt, namely, (Data) ═ a _ Decrypt (Secret1, true Random number (Random1), encrypted Data (En-Data)).

41e, the cloud server stores the decrypted data.

In the embodiment of the application, the body fat scale working in the broadcast mode encrypts data by using a preset key and broadcasts the encrypted data to the outside, and accordingly, the cloud server decrypts the encrypted data by using a locally pre-stored key. In the whole process, data are encrypted and transmitted, and the secret key cannot be transmitted in the air, so that the safety of the data is guaranteed. In addition, the body fat scale works in a broadcast mode, the broadcast mode has lower requirements on the computing capacity and hardware resources of the body fat scale, and the implementation cost of the body fat scale can be reduced. Furthermore, a distribution network process is provided for the body fat scale working in the broadcast mode, the body fat scale can be discovered and bound through the distribution network process, the cloud server and the intelligent sound box only need to process data packets from bound Bluetooth devices (or distributed Bluetooth devices), and do not need to process data packets from other unbound Bluetooth devices (or unconfigured Bluetooth devices), so that the probability of malicious attack on the cloud server or a network system can be reduced, and the safety of the system can be improved.

Fig. 4a is a schematic flowchart of a data transmission method provided in an exemplary embodiment of the present application, where the method is applied to a bluetooth device operating in a broadcast mode, and as shown in fig. 4a, the method includes:

41a, encrypting data to be transmitted by adopting a preset encryption algorithm and a key to obtain encrypted data;

42a, packaging the identity identification and the encrypted data of the Bluetooth equipment into a data packet;

43a, broadcasting data packets to the outside.

As for step 41a, in this embodiment, the data to be transmitted is data that the bluetooth device needs to send to the outside, and may be some data preset in the bluetooth device, or may be data generated by the bluetooth device in the using process. For example, if the bluetooth device is a weight scale, the data to be transmitted may be weight data acquired by the weight scale in the using process; if the Bluetooth equipment is a body fat scale, the body fat scale is used for weighing body fat data acquired in the using process; if the Bluetooth device is an intelligent bracelet, the data to be transmitted can be exercise data acquired by the intelligent bracelet in the using process; if the bluetooth device is a medical apparatus, the data to be transmitted may be blood oxygen, blood pressure, and other data acquired by the medical apparatus during the use process, which is not limited to this.

In this embodiment, the specific implementation of the preset key is not limited. For example, the key used by the bluetooth device may be configured during initialization of the bluetooth device. For another example, the key used by the bluetooth device may be preset in the bluetooth device during factory configuration of the bluetooth device. In addition, the preset key can be burnt into the nonvolatile memory NVM of the Bluetooth device in advance, and the data to be transmitted is encrypted by the key, so that the security of data transmission is guaranteed. NVM includes, but is not limited to, Flash, ROM, and the like.

In the present embodiment, the encryption algorithm used is not limited. For example, if the bluetooth device is more computationally powerful, a relatively complex software encryption algorithm may be used, such as a symmetric encryption algorithm. Preferably, a relatively simple hardware encryption algorithm, such as an XOR operation, an XNOR operation, etc., may be used in consideration of the limited computing power and hardware resources of the bluetooth device.

In the present embodiment, the physical variable on which the true random number a is generated is not limited, and may be, for example, hardware noise, a voltage value or a current value generated during the operation of the bluetooth device. Specifically, the true random number a may be generated according to a voltage value or a current value of the MCU of the bluetooth device. The algorithm for generating the true random number a according to the physical variable is not limited, and can adopt but not limited to: acquiring an instantaneous value of a physical variable by using the ADC to serve as a true random number A, wherein the true random number A is an instantaneous current value or a voltage value acquired by the ADC when the physical variable is a current or a voltage; and manually moving the mouse to reach a certain length, and inputting the motion track of the mouse within the length as an independent variable into a key generation tool to obtain a true random number A, and the like.

For step 42a, the identity of the bluetooth device may be any information capable of uniquely identifying the bluetooth device, such as a name, an ID, a serial number, or an abbreviation of the bluetooth device, which is not limited herein. It should be noted that the identity of the bluetooth device may include some functional descriptions related to the bluetooth device, and other information helpful for identifying the bluetooth device, besides information capable of uniquely identifying the bluetooth device. In an alternative embodiment, the product ID to which the bluetooth device belongs and the MAC address of the bluetooth device may be used as the identity of the bluetooth device. The product ID is used for uniquely identifying one type of Bluetooth equipment, for example, the product ID of the body fat scale is different from the product ID of the Bluetooth bracelet, and in addition, a plurality of identical Bluetooth equipment are arranged under one product ID, for example, the same series or the same generation of body fat scales produced by the same manufacturer correspond to the same product ID. The MAC address is used to uniquely identify a bluetooth device.

Optionally, if the true random number a is introduced in the process of encrypting the data to be encrypted in step 41 a. After the true random number A and the data to be transmitted are encrypted by adopting a preset encryption algorithm and a preset secret key to obtain encrypted data, the identity identification of the Bluetooth equipment, the true random number A and the encrypted data can be packaged into a data packet. Further, in step 43a, the data packet is broadcast.

For step 43a, the embodiment does not limit the specific implementation of the outbound broadcast packet. For example, the bluetooth device may broadcast the data packet once to the outside in a conventional communication manner. For another example, considering that the bluetooth device operates in a broadcast mode and has no interactivity, that is, only an external broadcast data packet is available, but data sent by other devices cannot be received, in order to solve the problem of non-interactive broadcast data loss, optionally, a certain broadcast time may be set, and then the same data packet is externally broadcast for multiple times within the set broadcast time, so as to improve transmission reliability; or, a certain number of broadcast times is set, and the same data packet is broadcast for multiple times according to the set number of broadcast times, so that the transmission reliability is improved. The set broadcast time may be, but is not limited to: 1 second, 3 seconds, 5 seconds, etc.; the set number of broadcasts may be, but is not limited to: 5 times, 10 times, 50 times, etc.

Optionally, before broadcasting the data packet to the outside, the method further includes: generating a network distribution package according to the identity of the Bluetooth equipment; and broadcasting the network distribution packet to the outside to initiate a network distribution process to the server equipment.
