Detailed Description
Conventionally, bluetooth beacon data is transmitted in clear text form by a wireless broadcast signal, and all beacon receiving devices can receive the broadcast signal and easily acquire the data, which provides a riding opportunity for illegal operation of illegal receivers. Once the bluetooth beacon data is illegally acquired, hackers have the opportunity to easily perform illegal cloning, illegal tampering and illegal tracking on the bluetooth beacon data, thereby misleading users and causing huge benefit loss to the users.
In view of this, the embodiment of the present invention provides a method for transmitting bluetooth beacon data, so as to solve the problem. Referring to fig. 1, in a network environment applied in the embodiment of the present invention, in a signal transmission range of a bluetooth beacon 11, a bluetooth beacon receiving device 12 and the bluetooth beacon 11 perform data transmission by using a bluetooth communication protocol supported by both sides; the bluetooth beacon receiving device 12 may also interact with a remote server 13 via a mobile communication network 14. In addition, the bluetooth beacon 11 (or the bluetooth beacon transmission device having the bluetooth beacon 11) may also be connected to a mobile communication network for data interaction with a server (not shown in fig. 1). The embodiment of the present invention does not limit the types of the bluetooth beacon receiving device 12 and the bluetooth beacon transmitting device, the protocol and the networking structure of the mobile communication network, and the specific implementation manner of the server.
The bluetooth beacon transmitting device and the bluetooth beacon receiving device 12 are substantially electronic terminals, and the actual entities thereof may be mobile devices such as smart phones, PDAs (Personal Digital assistants or tablet computers), and wearable devices with bluetooth transmission functions, which can be worn on limbs or embedded in clothes, ornaments, accessories, and the like.
As shown in fig. 2, the transmission method of bluetooth beacon data includes the following steps S11 to S13.
S11: and performing safety processing on the Bluetooth beacon data by adopting a preset algorithm.
The bluetooth beacon data referred to herein may refer to a part or all of PDUs (protocol data units) in the bluetooth low energy broadcast. The bluetooth beacon data described throughout the embodiments of the present invention may be designated as the same, and will not be described in detail below.
S12: and encapsulating the safely processed Bluetooth beacon data in a broadcast packet.
S13: and sending the broadcast packet to a beacon receiving device through a wireless frame, wherein the beacon receiving device is used for receiving the broadcast packet and analyzing to obtain Bluetooth beacon data.
The execution subject of each step may be a bluetooth beacon transmission device or a bluetooth beacon (e.g., bluetooth beacon 11 shown in fig. 1) itself, specifically including but not limited to a bluetooth device for tracking, logistics storage management, variable monitoring, message pushing and other application scenarios.
The security processing is equivalent to adding an authentication operation to the bluetooth beacon data, even if an unauthorized beacon receiving device receives a broadcast packet (i.e., a wireless broadcast signal) encapsulated with the bluetooth beacon data, the unauthorized beacon receiving device cannot acquire a reverse algorithm of a preset algorithm without acquiring a specific key adopted by the security processing, and cannot acquire the bluetooth beacon data through authentication, and certainly cannot adopt an adaptive measure, so that the bluetooth beacon data is favorably prevented from being illegally cloned, illegally tampered and illegally tracked, and the use security of the bluetooth beacon can be improved.
Taking an application scenario of order payment as an example, even if malicious beacon receiving equipment receives a broadcast packet, the malicious beacon receiving equipment cannot acquire a reverse algorithm of a preset algorithm, so that adaptive measures cannot be taken to decode the broadcast packet to successfully obtain bluetooth beacon data, and the malicious beacon receiving equipment cannot copy and clone the bluetooth beacon data onto a phishing server (also called an illegal server), so that payment information of a user cannot be cheated by using a false order and payment page, and the user loss is avoided.
For the application scenario of logistics storage management, an illegal beacon receiving device cannot decode the broadcast packet, and certainly cannot obtain the identity information of the bluetooth beacon from the broadcast packet, so that the bluetooth beacon cannot be tracked, that is, the embodiment of the invention can realize anti-tracking.
The preset algorithm refers to an operation method for performing security processing on bluetooth beacon data, and the specific content of the preset algorithm is different in different security processing modes. For example, if the security processing is encryption, the preset algorithm refers to an encryption algorithm; for another example, if the security processing is to generate a unique tag, the preset algorithm refers to a generation algorithm of a unique identifier or a unique ID; for another example, if the security process is to generate dynamic variables, the preset algorithm refers to an algorithm that generates dynamic variables. If the security processing is a combination of the above-mentioned multiple operation modes, the number of the preset algorithms may be multiple, and each algorithm is an algorithm adopted by a corresponding operation mode.
The preset algorithm may be written into the chip by the manufacturer when the bluetooth beacon (or the bluetooth beacon transmission device) is produced, and the execution of the preset algorithm may be performed by itself after the bluetooth beacon is started without depending on other instructions, or may be instructed to execute or stop the execution of the preset algorithm by other means, for example, by separately setting a switch for executing security processing.
The technical solutions of the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step, based on the following individual embodiments, fall within the scope of protection of the present invention. The following embodiments and their technical features may be combined with each other without conflict.
Fig. 3 is a flowchart illustrating a method for transmitting bluetooth beacon data according to a second embodiment of the present invention. Fig. 3 shows a method for transmitting bluetooth beacon data according to the embodiment of fig. 2. The transmission method includes the following steps S21-S23.
S21: a preset algorithm is used to generate a unique tag for the bluetooth beacon data.
S22: the unique tag and bluetooth beacon data are encapsulated in a broadcast packet.
S23: the method comprises the steps that a broadcast packet is sent to a beacon receiving device through a wireless frame, the beacon receiving device is used for receiving the broadcast packet and analyzing to obtain Bluetooth beacon data, the beacon receiving device calculates a unique label according to the obtained Bluetooth beacon data, if the calculated unique label is consistent with the received unique label, the received Bluetooth beacon data are real and not tampered, and the received Bluetooth beacon data can be regarded as authentication of the Bluetooth beacon data.
Bluetooth beacon data is essentially a string of numbers or characters, and the unique tag is a unique identification of the string of numbers or characters. .
The preset algorithm used for generating the unique tag may be a symmetric Encryption algorithm such as an AES (Advanced Encryption Standard) algorithm, a DES (Data Encryption Standard) algorithm, or other asymmetric Encryption algorithms.
The following is an example description taking the AES algorithm as an example. The AES algorithm is also called Rijndael encryption method, Bluetooth beacon data can be regarded as an original matrix, and a key generated by the AES algorithm performs corresponding operation on each byte in the original matrix, so that the unique label is finally obtained.
Referring to fig. 4, the unique tag is a new part of a PDU (protocol data Unit) in the bluetooth low energy protocol broadcast, and is transmitted through a radio frame together with other fields, such as a Preamble (Preamble), an Access code (Access Address), a protocol data Unit (protocol data Unit) (including bluetooth beacon data used for generating the unique tag), and a CRC (cyclic redundancy Check). It should be noted that: the unique tag and the original PDU form a new PDU.
The position of the unique tag in the broadcast packet PDU, for example, whether the unique tag is placed in the middle section or the rear section of the PDU, is not limited in the embodiments of the present invention, and only needs to meet the actual transmission requirement.
In addition to the beacon transmitting device, the key used by the preset algorithm of fig. 4 is known only to the intended beacon receiving device. After receiving a broadcast packet transmitted by a bluetooth beacon, the expected beacon receiving device generates a tag according to the received broadcast packet according to the step of generating the unique tag, that is, the beacon receiving device generates a tag according to the same preset algorithm, and if the generated tag is the same as the received unique tag, it indicates that the bluetooth beacon data has not been tampered. This can also be considered as authentication of the bluetooth beacon data.
Fig. 5 is a flowchart illustrating a method for transmitting bluetooth beacon data according to a third embodiment of the present invention. Fig. 5 shows another method for transmitting bluetooth beacon data according to the embodiment of fig. 2. The transmission method includes the following steps S31-S33.
S31: and encrypting the Bluetooth beacon data into a ciphertext by adopting a preset algorithm.
S32: and encapsulating the ciphertext into a broadcast packet.
S33: and sending the broadcast packet to a beacon receiving device through a wireless frame, wherein the beacon receiving device is used for receiving the broadcast packet and analyzing to obtain Bluetooth beacon data.
In the foregoing embodiments, the bluetooth beacon data is a string of numbers or characters displayed in clear text, which has a problem of low privacy. For this, the plaintext is encrypted into the ciphertext, and the preset algorithm used for generating the ciphertext may be an AES algorithm. The Bluetooth beacon data can be regarded as an original matrix, and a key generated by an AES algorithm performs corresponding operation on each byte in the original matrix, so that a ciphertext corresponding to the Bluetooth beacon data is finally obtained.
The field lengths of the ciphertext and plaintext bluetooth beacon data may be the same or different, and the specific requirement is determined according to the adopted preset algorithm.
As shown in fig. 6, the broadcast that is finally transmitted includes the bluetooth beacon data in the form of ciphertext, but also includes other fields, such as preamble, access code, other parts of PDU, CRC, etc. The position of the cipher text in the broadcast packet may be consistent with the position of the bluetooth beacon data originally expressed in the clear text form in the broadcast packet.
In addition to the beacon transmitting device, the key used by the preset algorithm of fig. 6 is known only to the intended beacon receiving device. After receiving the broadcast packet, only the expected beacon receiving device can successfully decrypt the ciphertext according to the reverse algorithm of the preset algorithm, so that the Bluetooth beacon data can be successfully obtained.
Other embodiments of the present invention may perform the aforementioned authentication and encryption operations on the bluetooth beacon data simultaneously, resulting in another broadcast packet. Fig. 7 is a flowchart illustrating a method for transmitting bluetooth beacon data according to a fourth embodiment of the present invention. Referring to fig. 7, a method for transmitting bluetooth beacon data according to the embodiment of fig. 2 includes the following steps S41-S43.
S41: and encrypting the Bluetooth beacon data into a ciphertext by adopting a preset algorithm, and generating a unique tag for the Bluetooth beacon data by adopting the preset algorithm, wherein the Bluetooth beacon data used for generating the unique tag can be data after encryption or before encryption.
The unique tag may also be encrypted or not encrypted if generated with the bluetooth beacon data prior to encryption.
S42: and encapsulating the unique label and the ciphertext into the broadcast packet.
S43: and sending the broadcast packet to a beacon receiving device through a wireless frame, wherein the beacon receiving device is used for receiving the broadcast packet and analyzing to obtain Bluetooth beacon data.
Based on this, please refer to fig. 8, the finally transmitted broadcast includes not only the bluetooth beacon data expressed in the form of ciphertext, but also a unique tag (which is a new part of PDU in the bluetooth low energy protocol broadcast), and of course, also includes other fields, such as preamble, access code, other parts of PDU, CRC, etc. For the positions of the ciphertext and the unique tag in the broadcast packet, reference may be made to the description of the foregoing embodiments.
In addition to the beacon transmitting device, the key used by the preset algorithm of fig. 8 is known only to the intended beacon receiving device. When the expected beacon receiving device receives a broadcast packet sent by a Bluetooth beacon, the expected beacon receiving device generates a label according to the same preset algorithm, and if the generated label is the same as the received unique label, the expected beacon receiving device indicates that the Bluetooth beacon data is not tampered. And only after the expected beacon receiving equipment receives the broadcast packet, the ciphertext can be decrypted according to the reverse algorithm of the preset algorithm, and the Bluetooth beacon data can be successfully obtained.
Compared with the embodiments respectively described in fig. 3 and fig. 5, this embodiment is equivalent to setting two authentication procedures for the transmission of the bluetooth beacon data, and having security measures of authentication and encryption, which can further improve the security of the use of the bluetooth beacon.
Fig. 9 is a flowchart illustrating a method for transmitting bluetooth beacon data according to a fifth embodiment of the present invention. As shown in fig. 9, the transmission method includes the following steps S51 to S53.
S51: and generating a dynamic variable, wherein the dynamic variable is a random variable or a variable changing along with time, the dynamic variable can be used as an initialization variable or a counter value in an encryption process, the Bluetooth beacon data is encrypted into a ciphertext by using a preset algorithm and the dynamic variable, and a unique tag is generated for the Bluetooth beacon data by using the preset algorithm. The bluetooth beacon data used to generate the unique tag may be data after encryption or before encryption. The unique tag may also be encrypted or not encrypted if generated with the bluetooth beacon data prior to encryption.
S52: and encapsulating the dynamic variable, the unique tag and the ciphertext into a broadcast packet.
S53: and sending the broadcast packet to a beacon receiving device through a wireless frame, wherein the beacon receiving device is used for receiving the broadcast packet and analyzing to obtain Bluetooth beacon data.
The dynamic variable may be a number or a string of characters. The dynamic variable may vary with time (in this case, a variable that varies with time) or aperiodically (in this case, a random variable, and a variable that varies with time) at some fixed period. The embodiment is not limited to the manner of generating the dynamic variable as long as the obtained dynamic variable is changed, and also is not limited to the number of field bits for generating the dynamic variable as long as the data transmission requirement can be satisfied.
In one embodiment, a random variable may be generated every hour, and the last two bits of the 16-ary random variable are used as dynamic variables; for another example, when generating bluetooth signal data, a random string of a fixed number of bits is generated, with the random string as a dynamic variable.
Referring to fig. 10, the broadcast finally transmitted by the bluetooth beacon includes the dynamic variable, the bluetooth beacon data in the form of ciphertext, and the unique tag. Of course, as mentioned above, the broadcast packet may also include other fields, such as a preamble, an access code, other PDU portions, and a CRC. In addition, as two new components in the PDU: the embodiment of the invention is not limited in the position of the PDU by the dynamic variable and the unique label, and only needs to meet the actual transmission requirement.
It should be understood that in other embodiments of the present invention, the broadcast packet finally transmitted by the bluetooth beacon may not include a unique tag, i.e., the broadcast packet may not include a unique tag, but rather include a dynamic variable, bluetooth beacon data in ciphertext form, and other fields as previously described.
In a specific application scenario, according to the specification of the bluetooth protocol, the bluetooth device may generate a random address or an address that changes with time, i.e., a broadcast device address, for external communication without exposing its own unique id, and may set a period for replacing the random address. Therefore, for the bluetooth beacon, a dynamic variable may be generated according to the address of the broadcasting device, for example, a few bit fields of the address of the broadcasting device may be used as the dynamic variable, or the address of the broadcasting device may be subjected to a certain regular mathematical operation or character string conversion to obtain the dynamic variable.
As shown in fig. 11 (a), an embodiment of the present invention may use the entire broadcaster address directly as a dynamic variable. It is understood that the full number of bits of the broadcaster address is directly used as the full number of bits of the dynamic variable, the broadcaster address being the dynamic variable.
As shown in fig. 11 (b), an embodiment of the present invention may use the entire broadcaster address as part of the dynamic variable. It is understood that the total number of bits of the address of the broadcasting device is a part of the number of bits of the dynamic variable, and the number of bits of the address of the broadcasting device is smaller than the number of bits of the dynamic variable.
As shown in (c) of fig. 11, an embodiment of the present invention may use a portion of the broadcaster address as the entire dynamic variable. It is understood that a part of the number of bits of the address of the broadcasting device is taken as the total number of bits of the dynamic variable, and the number of bits of the address of the broadcasting device is greater than the number of bits of the dynamic variable.
As shown in (d) of fig. 11, an embodiment of the present invention may use a part of the address of the broadcasting device as a part of the dynamic variable. It is understood that a part of the bits of the address of the broadcasting device is used as a part of the bits of the dynamic variable, and the bits of the address of the broadcasting device and the bits of the dynamic variable may be equal or unequal, and the embodiment is not limited.
In this embodiment, the bluetooth beacon converts the bluetooth beacon data into dynamic data that changes with time by using the dynamic variable and then transmits the dynamic data, so that an unauthorized beacon receiving device cannot obtain real and stable bluetooth beacon data, thereby being beneficial to preventing the bluetooth beacon data from being illegally cloned, illegally tampered and illegally tracked, and being capable of improving the use security of the bluetooth beacon.
In addition, the dynamic variable is generated according to the originally existing address of the broadcasting equipment, a random variable generation algorithm does not need to be additionally introduced, the calculation amount of generating the dynamic variable can be reduced, and the workload of the Bluetooth beacon is reduced.
Fig. 12 is a schematic structural diagram of a bluetooth beacon according to an embodiment of the present invention. The bluetooth beacon 120 includes a processor 121 and a memory 122, and the processor 121 and the memory 122 may be connected by a communication bus 123 for data or signal transmission.
The processor 121 is a control center of the bluetooth beacon 120, connects various parts of the entire bluetooth beacon 120 using various interfaces and lines, performs various functions of the bluetooth beacon 120 and processes data by running or loading a program stored in the memory 122, and calling data stored in the memory 122, thereby performing overall monitoring of the bluetooth beacon 120.

encapsulating the safely processed Bluetooth beacon data in a broadcast packet; and
and sending the broadcast packet to a beacon receiving device through a wireless frame, wherein the beacon receiving device is used for receiving the broadcast packet and analyzing to obtain the Bluetooth beacon data.
The security processing is equivalent to adding an authentication operation to the bluetooth beacon data, even if an unauthorized beacon receiving device receives a broadcast packet (i.e., a wireless broadcast signal) encapsulated with the bluetooth beacon data, the unauthorized beacon receiving device cannot acquire a reverse algorithm of a preset algorithm without acquiring a specific key adopted by the security processing, and cannot acquire the bluetooth beacon data through authentication, and certainly cannot adopt an adaptive measure, so that the bluetooth beacon data is favorably prevented from being illegally cloned, illegally tampered and illegally tracked, and the use security of the bluetooth beacon can be improved.
The preset algorithm refers to an operation method for performing security processing on bluetooth beacon data, and the specific content of the preset algorithm is different in different security processing modes. For example, if the security processing is encryption, the preset algorithm refers to an encryption algorithm; for another example, if the security processing is to generate a unique tag, the preset algorithm refers to a generation algorithm of a unique identifier or a unique ID; for another example, if the security process is to generate dynamic variables, the preset algorithm refers to an algorithm that generates dynamic variables. If the security processing is a combination of the above-mentioned multiple operation modes, the number of the preset algorithms may be multiple, and each algorithm is an algorithm adopted by a corresponding operation mode.
For different security processing manners, details of steps executed by the processor 121 to call the program may refer to the foregoing embodiments, and are not described in detail here.
It should be understood that, when implemented in a practical application scenario, the execution bodies of the above steps may not be the processor 121 and the memory 122, but may be implemented by other modules and units respectively, according to the type of the beacon transmission device to which the bluetooth beacon 120 belongs.
