一种基于密钥协商的UAV与用户的安全通信算法

A Secure Communication Algorithm Between UAV and User Based on Key Agreement

针对无人机与用户间进行通信时的安全问题,提出轻量级的安全认证和密钥协商(Se-cure Authentication and Key Agreement,SAKA)算法。SAKA算法采用轻量级的加密操作,完成无人机与用户间的安全认证,并保证无人机和用户的位置不泄露。同时,为了保证无人机与用户间的安全通信,无人机与用户在通信前相互认证,并建立会话密钥。性能分析表明,SAKA算法能防御典型的安全攻击。相比于同类的认证算法,SAKA算法在运算时间和通信成本方面具有更好的性能。

In order to solve the security issues of communication between unmanned aerial vehicles(UAV)and user,a lightweight secure authentication and key agreement(SAKA)algorithm is proposed.The SAKA algorithm adopts lightweight cryptographic operations to perform security authentication between UAV and user,and ensures that the positions of UAV and user are not compromised.At the same time,in order to ensure secure communication between UAV and user,UAV and user authenticate each other and establish session keys before communication.Performance analysis shows that the proposed SAKA algorithm can resist typical security attacks.Moreover,the SAKA algorithm has better performance in terms of running time and communication cost,compared with similar authentication algorithms.
