Design of Trusted Aviation Data Exchange Platform Based on Blockchain

Abstract

Based on the characteristics of blockchain technology, an aviation data exchange platform is designed to realize the rapid exchange of aviation data between business departments. The platform design adopts alliance chain and private chain. Each data production unit, such as relevant departments of air traffic control, airlines, airports, etc., has its own private chain. Multiple private chains form an alliance chain. In each private chain, there are servers, which store encrypted aviation data. The alliance chain builds alliance block based on the hash value of private chain block, and uses re-encryption to exchange data by changing encryption, the platform achieves data integrity, access control, exchange security and other security goals.
