Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort shall fall within the protection scope of the present specification.
In order to better understand the inventive concept of the present application, a communication system based on a remote control device in an embodiment of the present specification is first introduced. 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, and the like. The user terminal 110 may communicate with the server 120 based on base station communication. The user terminal 110 may also communicate with the remote control device 130 and the controlled device 140 by other wireless communication methods, for example, communication methods such as bluetooth communication may be used for communication.
Preferably, in this embodiment of the present specification, the user may take corresponding actions based on a specific application in the user terminal 110 to issue corresponding instructions.
The 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 with each other. These identification information and key are also stored in the server 120, so that the server 120 can look up whether the corresponding identification information exists, and look up the key corresponding to the identification information.
The remote control device 130 may communicate directly with the user terminal 110. After determining the corresponding controlled device 140, the remote control device 130 may communicate with the controlled device 140 and communicate the corresponding control instruction to the controlled device 140. The remote control device 130 key is enclosed 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 manufacturing 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, a 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 being able to successfully resolve, the controlled device 140 establishes a binding relationship with the remote control device 130, and is further able to communicate with the remote control device 130. The controlled device 140 may be a processor provided in other application devices, for example, the controlled device 140 may be a vehicle central controller, and may issue corresponding instructions to control operations of locking, opening doors, whistling, etc. of the vehicle. Specifically, the controlled device may be provided on an electric bicycle or an automobile. The controlled device 140 key is stored in the memory of the controlled device 140 itself, and the controlled device 140 key may be a key predetermined in 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 shows a case where one remote control device 130 and one controlled device 140 are bound, and in practical applications, the number of the remote control devices 130 bound to the controlled device 140 is not limited, and may be one or multiple.
Generally, for the convenience of the communication process, the above-mentioned controlled device 140 key and the remote control device 130 key are keys based on a symmetric encryption process, i.e., the same key can be used for encryption and decryption. In some embodiments, the controlled device 140 key and the remote control device 130 key may also be keys based on an asymmetric encryption process, that is, a key stored in the server 120 is different from a key stored in the controlled device 140 or the remote control device 130, so as to implement a process of public key encryption and private key decryption. For convenience of description, in the following embodiments, an example is adopted in which the controlled device 140 key and the remote control device 130 key are keys based on a symmetric encryption process, and the asymmetric encryption process may be implemented after adjustment is performed on this basis, which is not described herein again.
Limited by the size, purpose and manufacturing process of the remote control device 130 and the controlled device 140, the remote control device 130 and the controlled device 140 may not be able to directly communicate with the server 120, but only communicate with the user terminal 110 through short-range wireless communication, and therefore, the user terminal 110 needs to forward corresponding messages. In addition, the user terminal 110 also belongs to a 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 safety of the communication process.
Based on the communication system based on the remote control device, a communication method based on the remote control device in the embodiment of the present specification is introduced. The execution subject of the communication method based on the remote control equipment is the communication system based on the remote control equipment. As shown in fig. 2, the remote control device-based communication method may include the following implementation steps.
S210: and the user terminal sends the remote control equipment identifier and the controlled equipment identifier to the server.
After the user acquires the remote control device identifier and the controlled device identifier, the user can send the remote control device identifier and the controlled device identifier to the server.
The remote control device identification is used to uniquely identify the remote control device. The remote control device identifier may be an identifier directly obtained from the remote control device, or an identifier transmitted from the remote control device to the user terminal after the user terminal establishes communication with the remote control device.
In a specific example, a two-dimensional code image is arranged on the remote control device, and corresponds to a remote control device identifier. After the two-dimensional code image is obtained by using the terminal device, the two-dimensional code image can be analyzed to obtain a corresponding remote control device 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 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 identifier 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 encryption information.
The server, upon receiving the remote control device identifier and the controlled device identifier, 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 stored 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 using the controlled device key can be decrypted and read only by the controlled device, and the safety of data transmission is ensured.
The communication key may be a key generated by the server for communication between the remote control device and the controlled device. Since the bound remote control device and the controlled device may not have any communication before, and there is no case where the binding relationship is determined in advance, it is necessary to generate a communication key and inform the remote control device and the controlled device of the communication key, respectively.
In some embodiments, to ensure the security of the communication, the communication key may be a key randomly generated by the server. The specific random generation algorithm may be selected based on the actual application requirements, which is not limited.
After the communication key is generated, the communication key may be encrypted with the controlled device key. The specific encryption algorithm may be set based on the requirements of the actual application, which is not limited in this regard.
S230: the server sends the first encryption information to the user terminal.
Because the server and the controlled device cannot be in direct communication, information forwarding can be carried out based on the user terminal, namely the server firstly sends the first encryption information to the user terminal.
S240: and the user terminal sends the first encryption information to the controlled equipment.
Since 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 the decryption algorithm written in the memory of the controlled device in advance can be used for decrypting the first encrypted information to obtain the communication key.
When the first encryption information is received, the controlled device can trigger a corresponding instruction to realize the binding of the controlled device and the remote control device. And the controlled device may determine its own lookup identity in order to enable the remote control device to locate the controlled device. The search identifier may be a password set for wireless communication, for example, when 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 application, the requirement for uniquely determining the controlled device according to the search identifier may be set to other formats, which is not limited to this.
The search identifier may be a fixed identifier, or may be generated in real time for the current binding process, which is not limited to this.
S260: the controlled device sends the search identifier to the user terminal.
Because the server and the controlled device can not be in direct communication, information forwarding can be carried out based on the user terminal, namely the controlled device firstly sends the search identifier to the user terminal.
S270: the user terminal sends the search identifier to the server.
Since the server and the controlled device cannot communicate directly, information forwarding can be performed based on the user terminal, that is, the user terminal sends the search identifier to the server.
In some embodiments, in order to enable the server to clarify the controlled device corresponding to the search identifier, when the user terminal sends the search identifier, the user terminal may send the search identifier, the remote control device identifier, and the controlled device identifier together to the server, so as to ensure that the server can determine the remote control device and the controlled device corresponding to the search identifier, and further ensure the accuracy of the subsequent second encrypted information generation 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 to implement the subsequent communication process.
The server may determine the stored remote control device key from the remote control device identification. The key of the remote control equipment is also stored in the remote control equipment, so that the information encrypted by the key of the remote control equipment can be decrypted and read only by the remote control equipment, and the safety of data transmission is ensured.
The specific encryption algorithm type and encryption process may be set based on the requirements of the actual application, which is not limited in this regard.
S290: the server sends the second encryption information to the user terminal.
Because the server and the remote control equipment can not carry out direct communication, information forwarding can be carried out based on the user terminal, namely the server firstly sends the second encryption information to the user terminal.
S2100: and the user terminal sends the second encrypted information to the remote control equipment.
Since the server and the remote control device cannot communicate directly, information forwarding can be performed based on the user terminal, that is, the user terminal forwards the second encrypted information to the remote control device.
S2110: and the remote control equipment decrypts the second encrypted information by using the remote control equipment 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 written in the memory of the remote control device can be used for decrypting the second encrypted information to obtain the communication key and the search identifier.
S2120: and the remote control equipment determines the controlled equipment according to the search identifier.
The remote control device can determine the controlled device according to the search identifier. And determining the controlled device based on the search identifier may be directly establishing a communication link with the controlled device, or may be capable of realizing one-way communication from the remote control device to the controlled device. And after the remote control equipment transmits corresponding information to the controlled equipment and the controlled equipment verifies the information, the construction of a communication link between the remote control equipment and the controlled equipment is completed. The specific setting mode may be adjusted based on the actual application requirement, which is not limited.
S2130: the remote control device communicates with the controlled device based on the communication key.
When the remote control equipment needs to communicate with the controlled equipment, the remote control equipment and the controlled equipment both acquire the same communication key, so that the remote control equipment can encrypt information by using the communication key and send the encrypted information to the controlled equipment, and the safety of a communication process is ensured.
In some embodiments, after the controlled device receives the information and successfully decrypts the encrypted information by using the communication key, it indicates that the remote control device sending the information is the device to be bound, thereby implementing the binding between the remote control device and the controlled device.
In some embodiments, after the remote control device and the controlled device are successfully matched, that is, under the condition that the remote control device can 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 indicate a binding relationship between the remote control device and the controlled device.
After receiving the successful binding information, the user terminal can record the remote control device identifier and the controlled device identifier corresponding to the successful binding information, so that a user can directly check the corresponding binding relationship through the user terminal, and the use of the user is facilitated.
In addition, the user terminal can also forward the binding success information to the server, so that the server also records the binding relationship between the remote control device and the controlled device according to the binding success information, and the server can conveniently manage the corresponding relationship between different remote control devices and the controlled device.
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 operate 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.
And 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, the unbinding instruction may be forwarded by the user terminal with reference to the above process.
After the controlled device receives the unbinding instruction, the communication key stored by the controlled device and corresponding to the identification of the remote control device can be deleted. After the communication key is deleted, even if the encryption instruction or the encryption information sent by the remote control equipment is still received subsequently, 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 equipment and the remote control equipment is realized.
In addition, since the communication key can be randomly generated, the situation that the remote control device is controlled by the unbound remote control device when the communication key is repeatedly used is avoided.
Correspondingly, the unbinding instruction comprises an instruction encrypted by using a controlled device key so as to ensure the safety of the communication process.
In some embodiments, one controlled device may communicate with multiple remote control devices, and different remote control devices correspond to different communication keys, and the controlled device may decrypt the encrypted information based on the corresponding communication keys, thereby implementing corresponding communication procedures.
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 information encryption in the above process is summarized with reference to fig. 3, in which the communication between the server and the controlled device is encrypted based on the controlled device key, the communication between the server and the remote control device is encrypted based on the remote control device key, and the 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 is in an encryption state, and the user terminal only plays a role in forwarding messages and cannot directly decrypt the information, so that the safety of the communication process is ensured.
Based on the description of the above embodiments, it can be seen that the method not only realizes pairing between the remote control device and the controlled device, but also enables communication between the remote control device and the controlled device based on the communication key, thereby improving the security of communication between the devices. In addition, all the information in the binding process is encrypted information, and the user terminal cannot decrypt the encrypted information, so that the transmitted communication key and the search identifier cannot be decrypted, and the safety of the communication process is further improved.
