摘要:

随着民用无人机技术的发展,无人机所面临的安全问题逐渐暴露。基于控制链路伪造攻击原理,通过攻击实例证实民用无人机存在遥控数据安全强度过低的隐患,并提出一种基于加密算法的遥控数据保护方法。分析加密算法的选取原则,从安全和实现性能2个方面对AES、PRESENT和RC4这3种加密算法的可行性进行分析,选取AES算法对无人机系统控制链路中的遥控数据包进行加密。最后,利用不同遥控数据之间的差异系数和相关性系数评估该方法的有效性。实验结果表明,该方法能够有效提高民用无人机遥控数据的安全性。

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.

Key words: Unmanned Aerial Vehicle(UAV), control link spoofing attack, remote control data security, encryption algorithm, defense effectiveness evaluation, AES algorithm
