Abstract: A method for supervising a flight state of an unmanned aerial vehicle includes establishing a communication connection with a control terminal of the unmanned aerial vehicle, and receiving and storing an off-line flight certificate sent by the control terminal. The off-line flight certificate includes off-line flight parameters. The method further includes monitoring and restricting, in response to the unmanned aerial vehicle being in an off-line flight mode, a flight behaviour of the unmanned aerial vehicle in the off-line flight mode according to the off-line flight parameters in the off-line flight certificate.

Abstract: A secure communication method comprising obtaining a secret code generated in response to a first communication device being paired with a second communication device, obtaining a prestored product key, generating a module key based on the secret code and the product key, randomly generating a session key, obtaining a key sequence number, auto-incrementing the key sequence number, setting a sending sequence number with an initial value of zero, generating a key frame by performing a computation on the session key and a verification authentication code of the session key using the module key, sending a data packet including the key frame, the key sequence number, the sending sequence number, and a data type to the second communication device. The data type indicates that the data packet is a key data packet.

Abstract: A supervision method for a flight state of an unmanned aerial vehicle includes respectively establishing communication connections with the unmanned aerial vehicle and a supervision server, receiving identity information about the unmanned aerial vehicle and flight information about the unmanned aerial vehicle sent by the unmanned aerial vehicle, automatically sending the identity information about the unmanned aerial vehicle and the flight information to the supervision server in an on-line mode, receiving at least one of a flight restriction instruction or warning information sent by the supervision server, and forwarding the flight restriction instruction to the unmanned aerial vehicle, so that the unmanned aerial vehicle executes the flight restriction instruction, thereby restricting flight behaviour of the unmanned aerial vehicle in an on-line flight mode via the flight restriction instruction.
