An Authentication Scheme Based on Identity Encryption in UAV AD Hoc Network
With the continuous advancement of wireless communication technology,the application of unmanned aerial vehicle(UAV)ad-hoc networks in areas such as rescue,patrol,and reconnaissance has become widespread.However,due to the flexible and dynamic nature of the network structure and the lack of infrastructure support,UAV ad-hoc networks face significant identity security threats.Despite the existence of various third-party security solutions,the current approaches suffer from issues such as low performance and in-sufficient security,making them challenging to deploy effectively in UAV ad-hoc networks.To address these challenges,we propose an authentication scheme based on Identity-Based Encryption(IBE),which utilizes entity identity information as public keys.This approach eliminates the need to store additional public key information,thereby reducing key storage overhead.Additionally,the proposed scheme supports batch authentication,significantly enhancing the efficiency of the authentication process.Furthermore,by introducing hash chain technology,we effectively retain and reuse the state information obtained after the initial UAV authentication,thereby reducing the authentication costs for subsequent UAVs.Through formal security analysis,the proposed method is demonstrated to resist malicious attacks such as identity forgery and man-in-the-middle attacks.In comparison to existing solutions,the computational and storage overhead of the proposed scheme is lower.
