Research On Anti-Spoofing And Communication Encryption Technology Of Quadrotor Drone

With the rapid development of computer technology and miro-electronics,consumerclass civilian unmanned aerial vehicles rapidly spread.The most important representative of the civilian UAV market is the Quadrotor Drone.Since the emergence of the model in the consumer market,it has become a “start”.For example,in the news aerial,law enforcement picket,security monitoring,courier delivery,power inspection and other aspects of the increasingly prominent performance.Although the development of the Quadrotor Drone is good,but because of commercial companies in the product flight control system design,hardware manufacturing,cost control and other aspects of inadequate consideration,But in 2015,2016,the two years occurred within the number of four-wing UAV was hijacked in a sensitive area crash,directly used in violent terrorist attacks and other bad events.Thus giving consumers and the development of the entire civilian UAV industry have caused adverse effects.To this end,the Quadrotor Drone safety research has become an urgent trend.The Quadrotor Drone security research includes attack technology and defense technology.At present,the attacking technology mainly adopts the primary means of signal suppression and navigation information deception,and the defense method mainly adopts simple frequency hopping technology to resist the attack,which is not enough to solve the problem of attack and illegal abuse.This thesis is proposed in this case,based on the study of attack methods,to achieve the purpose of targeted defense.This thesis take the Quadrotor Drone as the object of study,and takes its communication security as the research content.From a local point of view,the Quadrotor Drone Communication actually includes navigation communication and remote control communication in 2 areas,remote control communication is subdivided into verfication communication and instruction communication from its communication phase.That is to say,the specific content of this thesis is the navigation communication and verification communication and instruction communication of the Quadrotor Drone.Specifically,the main research contents are as follows:1?Research on the navigation communication of Quadrotor Drone.The working principle of GPS navigation module is studied,a Anti-Navigation Spoofing System is put forward,a simulation experiment environment is built,and the simulation experment of the Quadrotor Drone deception and deception is carried out.2?The Quadrotor Drone id studied to verify the communication security problem.Verification communication is the first stage of telecontrol communication for the Quadrotor Drone.A new verification communication mechanism is proposed,which solves the hidden security problems of the current Quadrotor Drone verificaiton communication.Finally,the correctness of the mechanism is verified by simulation.3?The problem of instruction communication security for Quadrotor Drone is studied.Instruction communication is the second stage of remote control for Quadrotro Drone.A command communication encryption scheme based on RC4 algorithm,designed the encryption and decryption process,build a simulation environment,finally compared the encryption before and after the perfomance and effectiveness,and gives a concrete analysis of the experimental results.
