Detailed Description

The technical solutions of the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is apparent that the described embodiments are only some embodiments of the present specification, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.

In order to better understand the inventive concept of the present application, first, a communication system based on a remote control device according to an embodiment of the present specification will be described. As shown in fig. 1, the remote control device-based communication system 100 may include a user terminal 110, a server 120, a remote control device 130, and a controlled device 140.

The user terminal 110 is a device capable of directly interacting with a user. The user terminal 110 includes, but is not limited to, a PC, a mobile communication device, a wearable smart device, etc. The user terminal 110 may communicate with the server 120 based on base station communications. The user terminal 110 may also communicate with the remote control device 130 and the controlled device 140 by adopting other wireless communication methods, for example, communication methods such as bluetooth communication may be adopted.

Preferably, in the embodiment of the present specification, the user may take corresponding operations based on a specific application program in the user terminal 110 to issue corresponding instructions.

Server 120 may be a remotely located computer device. When the remote control device 130 and the controlled device 140 are produced, corresponding identification information and a key stored in the devices are associated. These identification information and keys are also stored in the server 120 so that the server 120 can find out whether corresponding identification information exists or not, and find out the key corresponding to the identification information.

The remote control device 130 may communicate directly with the user terminal 110. The remote control device 130 may communicate with the controlled device 140 and communicate corresponding control instructions to the controlled device 140 after determining the corresponding controlled device 140. The remote control device 130 key is stored in the memory of the remote control device 130 itself, and the remote control device 130 key may be a key that is predetermined during the production process and written into the memory of the remote control device 130. Accordingly, the remote control device 130 key is also recorded in the server 120.

Typically, one remote control device 130 can only communicate with the same controlled device 140 for a period of time.

The controlled device 140 may also communicate directly with the user terminal 110. After receiving the message sent by the remote control device 130 and successfully resolving the message, the controlled device 140 establishes a binding relationship with the remote control device 130, and further can communicate with the remote control device 130. The controlled device 140 may be a processor disposed in other application devices, for example, the controlled device 140 may be a vehicle central control, and may be capable of issuing corresponding instructions to control operations such as locking, opening a door, whistling, etc. of the vehicle. Specifically, the controlled device may be provided on an electric bicycle or an automobile. The memory of the controlled device 140 itself has a controlled device 140 key stored therein, where the controlled device 140 key may be a key predetermined during the production process and written into the memory of the controlled device 140. Accordingly, the controlled device 140 key is also recorded in the server 120.

It should be noted that fig. 1 only schematically illustrates the case where one remote control device 130 and one controlled device 140 are bound, and in practical application, the number of remote control devices 130 bound with the controlled device 140 may be one or more.

In general, the controlled device 140 key and the remote control device 130 key are keys based on a symmetric encryption process for convenience of a communication process, that is, the same key can be used for encryption and decryption. In some embodiments, the key of the controlled device 140 and the key of the remote control device 130 may also be keys based on an asymmetric encryption process, that is, the key stored in the server 120 is different from the key stored in the controlled device 140 or the remote control device 130, so as to implement the processes of public key encryption and private key decryption. For convenience of description, the key of the controlled device 140 and the key of the remote control device 130 are examples of keys based on a symmetric encryption process, and an asymmetric encryption process may be implemented after adjustment based on the key, which will not be described in detail.

Limited by the volume, use and manufacturing process of the remote control device 130 and the controlled device 140 themselves, the remote control device 130 and the controlled device 140 may not be able to communicate directly with the server 120, but only communicate with the user terminal 110 by means of short-range wireless communication, so that a corresponding message needs to be forwarded by the user terminal 110. In addition, the user terminal 110 is also part of the communication link, so that the user terminal 110 is prevented from directly acquiring unencrypted information while avoiding information being cracked in the communication link, so as to ensure the security of the communication process.

Based on the above communication system based on the remote control device, a communication method based on the remote control device according to an embodiment of the present specification is described. The execution subject of the communication method based on the remote control device is the communication system based on the remote control device. As shown in fig. 2, the remote control device-based communication method may include the following embodied steps.

S210: the user terminal sends the remote control device identifier and the controlled device identifier to the server.

After the user obtains the remote control device identifier and the controlled device identifier, the remote control device identifier and the controlled device identifier can be sent to the server.

The remote control device identifier is used for uniquely identifying the remote control device. The remote control device identifier may be an identifier directly obtained from the remote control device, or may be an identifier sent to the user terminal by the remote control device after the user terminal establishes communication with the remote control device.

In a specific example, the remote control device is provided with a two-dimensional code image, and a remote control device identifier is corresponding to the two-dimensional code image. After the two-dimensional code image is acquired by using the terminal equipment, the two-dimensional code image can be analyzed to obtain a corresponding remote control equipment identifier.

Correspondingly, the controlled device identifier is also used for uniquely identifying the controlled device. The controlled device identifier may be an identifier obtained from the controlled device, or may be an identifier obtained based on a binding relationship between the user terminal and the controlled device. For example, in the case where the controlled device is a vehicle, the corresponding controlled device identification may be determined directly based on the vehicle information stored in the user terminal.

S220: the server encrypts the communication key by using the controlled device key to generate first encrypted information.

The server, upon receiving the remote control device identification and the controlled device identification, may begin to process the binding relationship between the remote control device and the controlled device and the communication between the two.

In some embodiments, the remote control device identifier and the controlled device identifier may be included in a binding request sent by the user terminal, so that the server performs a corresponding binding operation after receiving the binding request.

The server may determine the saved controlled device key based on the controlled device identification. The controlled device key is also stored in the controlled device, so that the information encrypted by the controlled device key can be decrypted and read only by the controlled device, thereby ensuring the safety of data transmission.

The communication key may be a server generated key for communication between the remote control device and the controlled device. Since the bound remote control device and the controlled device may not have performed any communication before and there is no case of a predetermined binding relationship, it is necessary to generate a communication key and notify the remote control device and the controlled device of the communication key, respectively.

In some embodiments, to ensure security of the communication, the communication key may be a key randomly generated by the server. The specific random generation algorithm can be selected based on actual application requirements, and is not limited in this regard.

After the communication key is generated, the communication key may be encrypted with the controlled device key. The specific encryption algorithm can be set based on the actual application requirements, and is not limited thereto.

S230: the server transmits the first encrypted information to the user terminal.

Because the server and the controlled device cannot directly communicate with each other, information can be forwarded based on the user terminal, i.e. the server firstly sends the first encrypted information to the user terminal.

S240: the user terminal sends the first encryption information to the controlled device.

Because direct communication cannot be performed between the server and the controlled device, information forwarding can be performed based on the user terminal, that is, the user terminal sends the first encrypted information to the controlled device.

S250: and the controlled device decrypts the first encrypted information by using the controlled device key to obtain the communication key.

After the controlled device receives the first encrypted information, the controlled device key and a decryption algorithm which are written in the self memory in advance can be utilized to decrypt the first encrypted information to obtain a communication key.

When the first encryption information is received, the controlled device can trigger a corresponding instruction to realize the binding between the controlled device and the remote control device. In order to enable the remote control device to locate the controlled device, the controlled device may determine its own seek identity. The search identifier may be a password set for implementing wireless communication, for example, when a connection based on bluetooth communication is required between the controlled device and the remote control device, the search identifier may be a device identifier and a connection password determined when searching based on bluetooth communication. In practical applications, the requirements for uniquely determining the controlled device according to the search identifier may be set to other formats, which is not limited.

The searching identifier may be a fixed identifier, or may be generated in real time for the binding process, which is not limited.

S260: the controlled device sends the search identification to the user terminal.

Because the server and the controlled device cannot directly communicate with each other, information can be forwarded based on the user terminal, i.e. the controlled device firstly sends the search identification to the user terminal.

S270: the user terminal sends the search identification to the server.

Because the server and the controlled equipment cannot be directly communicated, information can be forwarded based on the user terminal, namely the user terminal sends the search identification to the server.

In some embodiments, in order to make the server able to determine the controlled device corresponding to the search identifier, when the user terminal sends the search identifier, the remote control device identifier and the controlled device identifier may be sent to the server together, so as to ensure that the server is able to determine the remote control device and the controlled device corresponding to the search identifier, and further ensure the accuracy of the subsequent second encryption information generating process and the sending object.

S280: the server encrypts the communication key and the search identifier by using the remote control device key to generate second encrypted information.

After receiving the search identifier, the server needs to send the communication key and the search identifier to the remote control device so as to realize the subsequent communication process.

The server may determine the saved remote control device key based on the remote control device identification. The remote control device key is also stored in the remote control device, so that the information encrypted by the remote control device key can be decrypted and read only by the remote control device, thereby ensuring the safety of data transmission.

The specific type of encryption algorithm and encryption process may be set based on the needs of the actual application, which is not limited.

S290: the server transmits the second encrypted information to the user terminal.

Because the server and the remote control device cannot directly communicate with each other, information forwarding can be performed based on the user terminal, i.e. the server firstly sends the second encrypted information to the user terminal.

S2100: the user terminal transmits the second encrypted information to the remote control device.

Because direct communication cannot be performed between the server and the remote control device, information forwarding can be performed based on the user terminal, i.e., the user terminal forwards the second encrypted information to the remote control device.

S2110: the remote control device decrypts the second encrypted information by using the remote control device key to obtain a communication key and a search identifier.

After the remote control device receives the second encrypted information, the remote control device key and the decryption algorithm which are written in the memory of the remote control device in advance can be utilized to decrypt the second encrypted information to obtain the communication key and the search identifier.

S2120: the remote control device determines the controlled device according to the search identification.

The remote control device can determine the controlled device according to the search identification. The controlled device can be directly constructed with the controlled device to complete the construction of a communication link based on the search identification, or can realize unidirectional communication from the remote control device to the controlled device. After the remote control device transmits corresponding information to the controlled device and the controlled device verifies the information, the construction of a communication link between the remote control device and the controlled device is completed. The specific setting mode can be adjusted based on actual application requirements, and is not limited.

S2130: the remote control device communicates with the controlled device based on the communication key.

When the remote control device needs to communicate with the controlled device, the remote control device and the controlled device acquire the same communication key, so that the remote control device can encrypt information by using the communication key and send the encrypted information to the controlled device, thereby ensuring the safety of the communication process.

In some embodiments, when the controlled device receives the information and successfully decrypts the encrypted information by using the communication key, the remote control device that sends the information is the device that needs to be bound, so that the binding between the remote control device and the controlled device is realized.

In some embodiments, after the remote control device is successfully matched with the controlled device, that is, the remote control device may successfully analyze the reply information fed back by the controlled device by using the communication key, the remote control device may send binding success information to the user terminal, where the binding success information is used to represent a binding relationship between the remote control device and the controlled device.

After receiving the binding success information, the user terminal can record the remote control equipment identifier and the controlled equipment identifier corresponding to the binding success information, so that the user can directly check the corresponding binding relationship through the user terminal, and the user is convenient to use.

In addition, the user terminal can also forward the binding success information to the server, so that the server can record the binding relationship between the remote control equipment and the controlled equipment according to the binding success information, and the server is convenient to manage the corresponding relationship between different remote control equipment and the controlled equipment.

In some embodiments, after the remote control device and the controlled device are successfully bound, there may be a case where the remote control device and the controlled device need to be unbound based on certain requirements. In this case, the user may perform an operation based on the user terminal to generate a corresponding unbinding request, where the unbinding request may include the remote control device identifier and the controlled device identifier.

After the user terminal sends the unbinding request to the server, the server can generate an unbinding instruction, wherein the unbinding instruction comprises the remote control equipment identifier. The server may send the unbinding instruction to the controlled device, and specifically may refer to the above procedure for forwarding by the user terminal.

After the controlled device receives the unbinding instruction, the communication key stored by the controlled device and corresponding to the remote control device identifier can be deleted. After deleting the communication key, even if the encryption instruction or the encryption information sent by the remote control device is still received later, the encryption instruction or the encryption information cannot be decrypted, and then the corresponding operation cannot be executed, so that the unbinding between the controlled device and the remote control device is realized.

In addition, as the communication key can be randomly generated, the condition that the communication key is controlled by the unbinding remote control device when the communication key is reused is avoided.

Correspondingly, the unbinding instruction comprises an instruction encrypted by using the key of the controlled equipment so as to ensure the safety of the communication process.

In some embodiments, one controlled device may communicate with a plurality of remote control devices, and in addition, different remote control devices correspond to different communication keys, and the controlled device may decrypt the encrypted information based on the corresponding communication keys, so as to implement a corresponding communication process.

Correspondingly, the communication key stored in the controlled device can be correspondingly stored based on the remote control device identifier, so that the corresponding communication key can be directly determined according to the received information, and the efficiency of the communication process is improved.

The process of encrypting information in the above process is outlined in connection with fig. 3, wherein communication between the server and the controlled device is encrypted based on the controlled device key, communication between the server and the remote control device is encrypted based on the remote control device key, and communication between the controlled device and the remote control device is encrypted based on the communication key. The communication between different terminals and the server and between different terminals are in an encrypted state, and the user terminal only plays a role in forwarding the message and cannot directly decrypt the information, so that the safety of the communication process is ensured.

Based on the description of the above embodiment, it can be seen that the method not only realizes pairing between the remote control device and the controlled device, but also can perform communication between the remote control device and the controlled device based on the communication key, thereby improving the safety of communication between the devices. In addition, all the information in the binding process is encrypted information, the user terminal cannot decrypt the encrypted information, so that the transmitted communication key and the search identifier cannot be cracked, and the safety of the communication process is further improved.

The execution subject of the communication method based on the remote control equipment is the user terminal. As shown in fig. 4, the remote control device-based communication method may include the following embodied steps.
