[0046] Unmanned Aerial Vehicle (UAV) is an aircraft that does not require a pilot on board and can operate through remote control or autonomous flight systems. With the development of drone technology, drones have gradually been applied to various industries, improving the work efficiency and production level of the industry. However, in some special scenarios, such as application scenarios involving regional geographic information, drones may involve sensitive data during operation, such as coordinates, images, cruise routes, cruise time, etc. If sensitive data is leaked, it may endanger data security and create security risks.

[0047] Therefore, an embodiment of the present invention provides a drone, which achieves the effect of ensuring the data security of the drone by setting a hardware encryption unit.

[0048] In this embodiment, a drone is provided. Figure 1 is a schematic diagram of the hardware mainboard structure of a drone according to an embodiment of the present invention. Figure 1 As shown, the UAV includes a flight control unit, a hardware encryption unit and a wireless communication unit.

[0049] The flight control unit (Flight Control System) is used to control the flight of the drone to ensure the stability and safety of the drone's working process. The drone also includes a data acquisition unit for collecting external data and transmitting it to the flight control unit. When the drone performs a work task, the flight control unit can collect data such as the attitude, position and speed of the drone through sensors in the data acquisition unit, such as gyroscopes, accelerometers, magnetometers, barometers, GPS, etc. The data acquisition unit can also include cameras, infrared sensors, laser radars, etc. mounted on the drone to obtain images and video data of the target area of ​​the work task. These data may be the target data required for the drone to perform the work task, and need to be fed back to the external system to which the drone belongs, such as a ground control station, a big data platform or a database, etc. However, these data may contain sensitive data, and if the sensitive data is leaked, it will cause harm. Therefore, the drone can send the collected sensitive data to the hardware encryption unit through the flight control unit.

[0050] The hardware encryption unit is used to receive the sensitive data generated by the flight control unit and encrypt the sensitive data. The hardware encryption unit includes an encryption algorithm with data encryption function, which can encrypt the received sensitive data according to a preset encryption method to generate encrypted data. The encryption method can be set according to actual needs, such as using symmetric encryption, asymmetric encryption, etc.

[0051] The wireless communication unit is used to send the data encrypted by the hardware encryption unit. After the hardware encryption unit encrypts the sensitive data, the generated encrypted data can be sent to the external system through the wireless communication unit to complete the work task. The wireless communication unit can also receive instructions from the external system and forward them to the flight control unit.

[0052] The UAV also includes a power unit, which includes a plurality of motors and an electronic speed regulator for controlling the speed of the motors. The power unit is used to provide the UAV with thrust and power required for flight. The electronic speed regulator in the power unit is connected to the flight control unit in communication. The electronic speed regulator can report the power data of the UAV to the flight control unit. The flight control unit can issue a power adjustment instruction (for example, a pulse width modulation signal) to the electronic speed regulator according to the power data and the current target power. The electronic speed regulator can adjust the speed of each motor according to the power adjustment instruction, thereby controlling the flight state of the UAV.

[0053] The drone also includes a battery pack for supplying power to a power unit, a flight control unit, and a hardware encryption unit respectively.

Figure 2 As shown, in an optional implementation, the hardware encryption unit includes a true random number generator, a pseudo-random number generator, a key management module, and an encryption processing unit.

[0055] The true random number generator (TRNG) can generate completely unpredictable random numbers based on essentially random physical processes, and the pseudo-random number generator (PRNG) can generate random numbers that appear random but are actually generated by a deterministic algorithm. The true random number generator and the pseudo-random number generator are used to collaboratively generate random number sequences and generate data keys accordingly. The types of the true random number generator and the pseudo-random number generator can be selected according to actual needs. For example, the true random number generator can be a thermal noise generator, a photoelectric generator, a quantum generator, an atmospheric noise generator, etc. The pseudo-random number generator can choose to generate pseudo-random numbers through algorithms such as the linear congruential algorithm, the middle square algorithm, or the Mersenne rotation algorithm.

[0056] The key management module is used to store the data key and provide the data key when encryption is required. When the data key needs to be updated, the key management module can also automatically update the data key.

[0057] The encryption processing unit generates an encrypted data file based on the data key and the sensitive data. When encryption is required, the flight control unit sends the sensitive data (original sensitive data) to the encryption processing unit, and the encryption processing unit sends an instruction to call the data key to the key management module. After receiving the instruction to call the data key, the key management module outputs the data key to the encryption processing unit. The encryption processing unit encrypts the sensitive data using the data key to generate an encrypted data file, and sends the encrypted data file to the flight control unit. The encrypted data file contains the data key ciphertext and the encrypted sensitive data (corresponding to Figure 2 confidential data in the

[0058] In an optional embodiment, the hardware encryption unit also includes an MCU (Microcontroller Unit) coprocessor. The MCU coprocessor is used to control the true random number generator and the pseudo-random number generator to work together. The MCU coprocessor can control the true random number generator and the pseudo-random number generator to collaborate to generate a random number sequence, and process the random number sequence through a key generation algorithm (such as a symmetric encryption algorithm and an asymmetric encryption algorithm) to generate a data key, which is sent to a key management module for storage. The hardware encryption unit also includes a timer and a dynamic memory, the timer is used to assist the MCU coprocessor in controlling the true random number generator and the pseudo-random number generator to work together, and the dynamic memory is used to provide storage support in the process of generating data keys.

Figure 3 is a circuit diagram of a hardware encryption unit according to an embodiment of the present invention. Figure 3As shown, the true random number generator, pseudo-random number generator, timer, and watchdog timer are respectively connected to the bridge chip Bridge through the APB (Advanced Peripheral Bus, a low-power interface protocol) bus, and the bridge chip Bridge is communicated with the MCU coprocessor. The dynamic memory includes ROM (Read-Only Memory), RAM (Random Access Memory) and flash memory FLASH. The MCU coprocessor is connected to ROM, RAM and flash memory FLASH respectively. ROM is used to store information such as firmware, RAM is used to provide dynamic cache support, and flash memory is used to provide functions such as data key storage.

[0060] In an optional implementation, the hardware encryption unit further includes an AHB (Advanced High Performance Bus, used for connection between high-performance modules) bus, and the encryption engine is connected to the bridge chip via the AHB bus. Specifically, the encryption engine includes a symmetric encryption engine and an asymmetric encryption engine, and the symmetric encryption engine and the asymmetric encryption engine are connected to the bridge chip via the AHB bus.
