Detailed Description
In the above-described aspect, any one of the transmitters may negotiate with the receiver and obtain a negotiated key to realize range remote control of a target device equipped with the receiver, and in addition to this, in order to improve security, the transmitter may be preset with a corresponding first key, and the receiver may pre-store first keys of all authenticated (i.e., secure) transmitters, and at this time, the receiver may authenticate the transmitter with the first key according to information transmitted by the transmitter, thereby realizing negotiation with only the transmitter storing the same first key and obtaining a target key for interaction.
However, this means that the receiver needs to pre-store the first secret keys of all authenticated transmitters to negotiate with the secure transmitter, and when the receiver needs to negotiate with the transmitter to be authenticated, the receiver often cannot negotiate the secret key with the transmitter to be authenticated in time.
In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all 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 belong to the protection scope of the present specification.
Based on the above problem, in the radio frequency remote control method provided in the embodiments of the present specification, a negotiation platform is introduced, where the negotiation platform stores information of each authenticated transmitter, and can flexibly add or delete the stored information of the transmitter, for example, the information of each transmitter may be stored in a form of a database, so that the transmitter may be verified by a negotiation center, and when the transmitter passes verification, a target key for a session with the receiver is generated for the transmitter and the receiver.
The radio frequency remote control method provided in the embodiments of the present specification can be applied to the field of unmanned driving, and is used for the transmitter to transmit a control instruction to a receiver of an unmanned device so as to realize control of the unmanned device.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a radio frequency remote control method provided in an embodiment of the present specification.
The embodiment of the specification provides a radio frequency remote control system, which comprises a transmitter, a receiver and a target device carrying the receiver.
The target device may be an unmanned device, such as an unmanned vehicle, an unmanned aerial vehicle, or the like, and the unmanned device implemented in this specification may be used in the field of logistics distribution, and particularly may be used for takeaway distribution.
The transmitter and the receiver are corresponding transmitting and receiving devices, and the type of the signal transmitted by the transmitter is the type of the signal received by the receiver, for example, the signal transmitted by the transmitter may include Near Field Communication (NFC), Radio Frequency Identification (RFID), Radio Frequency Communication (RF), and the like, which is not limited in this specification.
After the transmitter and the receiver negotiate a corresponding target key, the transmitter and the receiver may be considered as a corresponding pair of transmitting and receiving devices, and at this time, the transmitter may control the target device equipped with the receiver by sending a control instruction to the receiver. The embodiments in this specification do not limit the types of target devices, and may be unmanned vehicles, unmanned aerial vehicles, and the like, and the following portions of this specification take the target device as an unmanned vehicle as an example for illustration only.
According to the type of the controlled target device, the transmitter may instruct the drone to perform different types of actions through the control command, for example, the drone may be controlled to unlock, brake, and the like, and when the target device is a drone, the drone may be instructed to fly by the control command, and the like, which is not limited in this specification.
As shown in fig. 1, the radio frequency remote control method provided in real time in this specification is divided into a negotiation stage and a remote control stage.
In the negotiation stage, the negotiation platform, the transmitter and the receiver negotiate a target key for encrypting the interaction in the remote control stage, and in an embodiment of the present specification, the target key of the transmitter and the target key of the receiver may be the same key for symmetric encryption.
The device is limited by the transmitter, which is simple in structure, usually the transmitter is a single chip, and the System mounted by the transmitter is usually a Real Time Operating System (RTOS), so the transmitter usually only includes a radio frequency communication function, and cannot interact with the transmitter through a cellular network, an ethernet network, and the like, and the computing resources are also few, and therefore, in the embodiment of the present specification, the target key of the transmitter negotiated in the negotiation stage is the same as the target key of the receiver.
In the remote control stage, the transmitter encrypts the control command according to the negotiated target key and transmits the encrypted control command to the target device with the receiver, so that the effect of safely transmitting the control command is achieved.
Specifically, after the target key is determined, the target device may be controlled by using the method shown in fig. 2.
S200: determining a target device, generating a control instruction for the target device,
S204: and encrypting the control command according to a target key negotiated in advance by any method.
S206: and sending the ciphertext of the control instruction to a receiver carried by the target equipment by adopting a radio frequency transmission mode, so that the receiver responds to the received ciphertext of the control instruction, and determines the plaintext of the control instruction according to the target secret key, so that the target equipment executes the operation indicated by the control instruction according to the control instruction.
After generating the control instruction for the target device, the transmitter may encrypt the control instruction with the target key, and send the encrypted control instruction to the receiver, so that the receiver obtains a plaintext of the control instruction according to the target key stored in the receiver, thereby controlling the target device.
In an embodiment of this specification, each transmitter may correspond to a plurality of receivers, each receiver may also correspond to a plurality of transmitters, each corresponding target key may be different from each target key, and when a receiver receives a signal encrypted by a target key that is not stored by the receiver, the receiver may consider that the signal is a non-control command that is not negligible. Furthermore, when the receiver receives the unencrypted control command, the unencrypted control command can be considered to be sent by the untrusted transmitter, so that the unencrypted control command is ignored, and the security of the target device is ensured. After the receiver receives the control instruction, a corresponding acknowledgement signal may also be returned to the transmitter.
Fig. 1 shows a radio frequency remote control method in an embodiment of this specification, where in a negotiation stage, a transmitter may generate identification information and check information of itself and send the identification information and the check information to a receiver, the receiver forwards the identification information and the check information of the transmitter to a negotiation center, and the negotiation center verifies the transmitter according to the received identification information and check information of the transmitter, and specifically, the negotiation center may store the identification information and the check information of each transmitter, so that the negotiation center may determine the check information corresponding to the identification information of the transmitter according to the identification information of the transmitter and compare the check information with the check information of the transmitter forwarded by the receiver to obtain a verification result of the transmitter.
In an embodiment of this specification, the negotiation center may correspondingly store three types of information, including: identification information, keys, and verification information such that the three types of information stored are for the same transmitter.
Fig. 3 shows a radio frequency remote control method in the negotiation stage of the present specification, taking the negotiation center as the executing body.
S300: and responding to the received identification information and the verification information of the transmitter forwarded by the receiver, and verifying the transmitter according to the identification information of the transmitter and the verification information of the transmitter.
The transmitter may be preset with a first secret key, for example, the first secret key may be written on the transmitter during a production process of the transmitter, in this case, the check information sent by the transmitter to the receiver may be a ciphertext of the check information encrypted with the first secret key, and of course, the ciphertext of the first check information and the plaintext of the first check information may be forwarded to the negotiation center together with the plaintext of the transmitter, so that the check center determines the first secret key stored corresponding to the identification information according to the plaintext of the identification information of the transmitter, and decrypts the received ciphertext of the check information of the transmitter according to the first secret key.
Specifically, the decrypted plaintext of the transmitter verification information may be compared with the pre-stored verification information corresponding to the identifier information of the transmitter, so as to determine a comparison result, and determine whether the transmitter verification passes or not according to the comparison result. Generally, if the comparison result is the same, the transmitter verification result can be considered to pass.
S302: when the transmitter check passes, a target key is generated.
In the embodiments of the present specification, the generated target key may be a random number, and the random number may be a fixed length, and may be 16 bits, for example.
S304: and sending the target key to a receiver so that the receiver stores the target key and forwards the target key to a transmitter, and controlling the target equipment carrying the receiver by the transmitter through a control command encrypted by the target key.
The negotiation center may then send the generated target key to the receiver, store it by the receiver itself, and forward it to the transmitter.
In an embodiment of this specification, in order to ensure security when the receiver sends the target key to the transmitter, the negotiation center may encrypt the target key with the first secret key after generating the target key, so that the receiver forwards the received target key encrypted with the first secret key to the transmitter. And the transmitter adopts the first secret key to decrypt according to the received ciphertext of the target secret key to obtain the plaintext of the target secret key.
In an embodiment of the present specification, a communication environment between the receiver and the negotiation center may be considered to be secure, and therefore, the target key sent by the negotiation center includes, in addition to the target key encrypted by the first secret key for the receiver to forward to the transmitter, a plaintext of the target key, so that the receiver directly stores the plaintext of the target key.
The above is an embodiment of a radio frequency remote control method in this specification.
In the radio frequency remote control method provided in the foregoing embodiment, the check information sent by the transmitter is encrypted by using a first secret key, and the negotiation center decrypts a ciphertext of the check information of the transmitter according to the stored first secret key corresponding to the identification information of the transmitter to obtain the check information, that is, a secret key predetermined for the transmitter is the same as that stored in the negotiation center in advance, and the encryption of the check information is symmetric encryption.
In addition to the need to authenticate the transmitter, another embodiment of this specification requires that the receiver be authenticated and that the target key be generated only if both the transmitter and the receiver are verified.
Specifically, the receiver generates its own identification information and verification information, and sends the own identification information and verification information to the negotiation center, and the negotiation center may determine a verification result of the receiver according to the identification information and verification information of the receiver through any one of the above-mentioned verification transmitters, and similar to the transmitter, the second secret key determined in advance for the receiver may be a second secret key corresponding to the identification information of the receiver stored in the negotiation center, but the secret key determined in advance for the receiver threshold may also be a fourth secret key corresponding to the second secret key corresponding to the identification information of the receiver stored in the negotiation center, and the second secret key and the fourth secret key are asymmetrically encrypted.
In this case, after determining the target key, the negotiation center may encrypt the target key with the first key and the second key, respectively, and obtain a first ciphertext of the target key encrypted with the first key and a second ciphertext of the target key encrypted with the second key, and send the first ciphertext and the second ciphertext to the receiver.
The receiver stores the second ciphertext and obtains the plaintext of the decrypted target key by using the second key or the fourth key stored in the receiver, and in addition, the receiver also forwards the first ciphertext to the transmitter, so that the transmitter obtains the plaintext of the decrypted target key according to the first key or the third key.
The above is an example of the negotiation phase provided for embodiments of the present specification.
Because the negotiation platform stores the information of each authenticated transmitter and can flexibly add or delete the stored information of the transmitters, for example, the information of each transmitter can be stored in a database form, so that the transmitters can be verified through the negotiation center, and when the transmitters pass the verification, a target secret key used for conversation with the receiver is generated for the transmitters and the receiver.
In addition, when the transmitter is lost, the negotiation platform may instruct the receiver to delete the transmitter's corresponding target key to prevent theft of the transmitter's target device.
The above radio frequency remote control method provided for one or more embodiments of the present specification is based on the same idea, and the present specification further provides a corresponding radio frequency remote control device, as shown in fig. 2 and fig. 3.

The present specification also provides a computer-readable storage medium storing a computer program, which is operable to execute the above-described radio frequency remote control method.
The present specification also provides a schematic structural diagram of the electronic device shown in fig. 4. As shown in fig. 4, at the hardware level, the electronic device includes a processor, an internal bus, a memory, and a non-volatile memory, but may also include hardware required for other services. The processor reads the corresponding computer program from the nonvolatile memory into the memory and then runs the computer program to realize the radio frequency remote control method.
Of course, besides the software implementation, the present specification does not exclude other implementations, such as logic devices or a combination of software and hardware, and the like, that is, the execution subject of the following processing flow is not limited to each logic unit, and may be hardware or logic devices.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.
As will be appreciated by one skilled in the art, embodiments of the present invention may be provided as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.
