A lightweight dynamic two-way identity authentication method for unmanned aerial vehicles

By using a dynamic two-way authentication method that pre-shares a root key between the UAV and the ground control station, and employing lightweight computational processes such as XOR and bitwise operations, dynamic authentication factors and session key components are generated. This solves the problems of lightweight and security in UAV communication authentication, and achieves efficient and reliable two-way authentication and secure data transmission.

Abstract

The application discloses a kind of unmanned plane lightweight dynamic bidirectional identity authentication method, it is applied to the system including ground control station and unmanned plane, ground control station and unmanned plane pre-share a same root key, method executes following steps in order: S1: ground control station initiates challenge step: ground control station generates first random number, and first random number is sent as challenge information to unmanned plane;S2: unmanned plane response and first authentication step: unmanned plane receives first random number, generates second random number;Unmanned plane is based on first random number, second random number and pre-shared root key, executes first preset dynamic calculation process, generates first authentication factor and first session key component;Then, unmanned plane second random number and first authentication factor are sent to ground control station.The application can realize lightweight bidirectional authentication, and safe and efficient adaptation unmanned plane communication.
