An Identity Authentication Scheme Based on SM2 Algorithm in UAV Communication Network

Abstract

With the advancement of technology, the collaborative networking of multiple UAVs has become a mainstream trend. Due to the characteristics of UAV communication networks, there are many security issues with their communication networks. At present, the UAV communication network needs a secure and efficient authentication scheme. In this paper, we optimise an UAV authentication scheme based on the SM2 algorithm, design a two‐way authentication mechanism to improve the security of the authentication scheme, and adopt the method of preshared secret information instead of digital signatures to improve the efficiency of authentication. Subsequently, the safety proof was based on the Dolev‐Yao model. Finally, simulation experiments demonstrate that the scheme is more efficient in authentication compared to other similar authentication schemes and meets expectations.
