With the advent of the 5G era, the number of UAV (Unmanned Aerial Vehicle) has grown dramatically. Accordingly, UAV need more computing and storage capabilities to complete a variety of tasks (including some collaborative tasks). To meet the requirements of UAV terminals, edge computing nodes and storage devices need to be deployed. But the problem of trust between edge computing nodes will lead to a series of data security problems. The blockchain features, which contain detrust, immutable, decentralized, can solve this problem properly. Therefore, this paper establishes an aviation terminal data security architecture based on the blockchain. Edge computing nodes and storage devices provide computing and storage resources for UAVs. As the core operating mechanism of the architecture, blockchain technology guarantees that the system has Byzantine fault tolerance performance through its consensus algorithm. The blockchain data structure under this architecture also guarantees that the data access records of all nodes will be written on the ledger and the ledger is stored by all miner nodes.
