A Distributed Authentication Protocol Using Identity-Based Encryption and Blockchain for LEO Network

摘要

LEO satellite-based mobile communication networks have gained enormous attention with the development of communication technology. However, the centralized authentication protocol in traditional satellite networks cannot accommodate to LEO satellite networks with frequent link switching. This paper proposes a fast and efficient authentication protocol in LEO satellite network by combining identity-based encryption and blockchain technology. We simulate the protocol in OPNET for validation with the node modules built in LEO satellite network. The new protocol demonstrates significant advantages in both performance and scalability with less communication overhead for different authentication scenarios in LEO satellite network.
