Abstract:

With the development of the civilian Unmanned Aerial Vehicle (UAV) technology,the security problem for UAV is gradually exposed.Based on the principle of control link spoofing attack,it is proved that the security intensity of remote control data is too low for civilian UAV by an attack example,and a remote control data protection method based on encryption algorithm is proposed.The selection principle of encryption algorithm is discussed,and the feasibility of three encryption algorithms AES,PRESENT and RC4 are analyzed from two aspects of security and performance.The AES algorithm is selected to encrypt the remote control data packet in the control link of UAV system.Finally,the effectiveness of the method is analyzed quantitatively by using the coefficient of difference and correlation between different remote control data.Experimental results show that this method can effectively improve the safety of remote control data for civilian UAV.
