1. An authentication system for preventing modification of an unmanned aerial vehicle, comprising:
- a main control terminal, comprising;
a first database configured to store authentication data, authenticated data and control data;
a first encryption and decryption circuit electrically coupled to the first database; and
a first transceiver electrically coupled to the first encryption and decryption circuit; and
at least one electronic governor, comprising;
a second transceiver configured to perform data transmission to and from the first transceiver;
a second encryption and decryption circuit electrically coupled with the second transceiver;
a second database configured to store the authentication data which is decrypted; and
a driver electrically coupled with a motor and configured to control the motor;
wherein, the main control terminal and the at least one electronic governor are installed on the unmanned aerial vehicle, and when the main control terminal and the at least one electronic governor are electrically coupled to each other and the main control terminal is started in order to enter an authentication stage,the first encryption and decryption circuit encrypts the authentication data stored in the first database and transmits the encrypted authentication data to the second transceiver via the first transceiver,then, the second encryption and decryption circuit decrypts the received authentication data and stores the authentication data in the second database,after that, the second encryption and decryption circuit encrypts the authentication data and transmits the encrypted authentication data to the first transceiver via the second transceiver,then, the first encryption and decryption circuit decrypts the received authentication data and determines whether the decrypted authentication data is the same as the authenticated data stored in the first database,such that when the decrypted authentication data is the same as the authenticated data stored in the first database, then the main control terminal enters a control stage,wherein the first encryption and decryption circuit encrypts the control data and transmits the encrypted control data to the second transceiver via the first transceiver, the second encryption and decryption circuit receives and decrypts the encrypted control data generating a control signal, and the driver controls a rotational speed of the motor according to the control signal.

Abstract
An authentication system and method for an electronic governor of an unmanned aerial vehicle is disclosed. By employing reciprocative authentication and encryption mechanisms between a main control terminal and an electronic governor, the use of a modified electronic governor is prevented and thus the illegal use of UAVs is also prevented. Moreover, the provided electronic governor may be operated in dual-mode to extend its compatibility to conventional main control terminals.

6. An authentication method for providing modification of an unmanned aerial vehicle, the authentication method comprising the steps of:
-
disposing a main control terminal and at least one electronic governor on the unmanned aerial vehicle; electrically coupling the main control terminal with the at least one electronic governor, and starting the main control terminal; in an authentication stage, encrypting an authentication data stored in a first database, by a first encryption and decryption circuit; transmitting the encrypted authentication data to a second transceiver via a first transceiver; receiving the encrypted authentication data, and decrypting the encrypted authentication data by a second encryption and decryption circuit, and storing the authentication data in a second database; encrypting the authentication data again, by the second encryption and decryption circuit; transmitting the encrypted authentication data to the first transceiver via the second transceiver; decrypting the received authentication data, by the first encryption and decryption circuit; determining whether the received authentication data is the same as the authenticated data stored in the first database, such that when the received authentication data is the same as the authenticated data stored in the first database, then the main control terminal enters a control stage, and the control stage comprising the steps of; encrypting the control data by the first encryption and decryption circuit and transmitting the encrypted control data to the second transceiver via the first transceiver; decrypting the received control data by the second encryption and decryption circuit wherein the decrypted control data results in a control signal; and controlling a rotational speed of a motor by a driver according to the decrypted control signal. - View Dependent Claims (7, 8, 9, 10)
