A Blockchain-Based Secure ADS-B System

Due to its advantages such as high precision and ease of use, the Automatic Dependent Surveillance-Broadcast (ADS-B) system has surpassed radar and is more widely utilized in air traffic management. However, security issues within the ADS-B system, such as lack of identity authentication, inability to ensure data integrity, and susceptibility to single-point failures, hinder its further development by allowing attackers to easily disrupt the system. In order to address these issues and provide security while maintaining performance for the ADS-B system, we conduct the following research. Firstly, we select a signature algorithm with a signature length of only | Z(q)* |, which ensures security while maintaining high system performance. Secondly, we design a blockchain-based secure ADS-B system to guarantee system security, incorporating a multi-leader BFT protocol where all nodes can act as leader to propose transactions, thus reducing transmission overhead and increasing throughput. Finally, we conduct performance evaluation of the system, demonstrating that our solution can achieve all stated security objectives while ensuring high system performance.
