Abstract:

With the development of drone technology, Internet of drones(IoD) is becoming more and more popular, and the security of IoD has also become a hot topic in academic circles. To solve the security problems faced by IoD, it is very important to study and design a secure, efficient and lightweight authentication key agreement protocol. In 2021, HUSSAIN et al. proposed a key agreement protocol for IoD authentication key agreement based on elliptic curve encryption algorithm. This paper found that this protocol can be suffered from serious security attacks such as drone impersonation attack, session key leakage attack and so on. Aiming at the security problems faced by Hussain et al., this paper proposed a new authenticated key agreement scheme based on multi-factors. The scheme is based on secure sketch algorithm and elliptic curve encryption algorithm, which can effectively solve the security threats faced by HUSSAIN et al.’s scheme. What’s more, the proposed scheme can realize access control also. From security analysis, security proof and simulation experiments, the result shows that the proposed scheme has higher security, although the computational and communication overhead has increased slightly.
