摘　　要：各航空企业的物流系统普遍存在数据集中存储、易受攻击且安全性低的问题,而结合区块链技术构建物流平台可以有效解决这一问题。文中基于区块链技术,将信息分布处理、链式存储、认证机制、智能合约应用于数据库搭建和订单状态转换,达到了物流平台去中心化的设计目的。在平台设计的过程中,由编写的网页及两个客户端采集并展示信息,后台信息按照权限等级分别存储于数据库和区块链。数据库的读写主体采用共识机制认证,由智能合约实现。航空物联网使得各个物流环节的完成信息可以实时传送至区块链中,触发订单状态修改的智能合约,直至完成订单、转移支付。对平台进行性能和安全测试的结果表明,系统运行平稳且安全、可靠,综合性能可以满足5000位用户并发读写的需求。The logistics systems of various aviation companies generally have the problems of centralized data storage,vulnerability to attacks and low security,and the construction of a logistics platform combined with blockchain technology can effectively solve this problem.Based on blockchain technology,this article applies information distributed processing,chain storage,authentication mechanism,and smart contracts to database construction and order status conversion,achieving the design goal of decentralization of the logistics platform.In the process of platform design,the written webpage and two clients collect and display information.The background information is stored in the database and the blockchain according to the authority level.The main body of the database is authenticated by a consensus mechanism and implemented by smart contracts.The aviation Internet of Things enables the completion information of various logistics links to be transmitted to the blockchain in real time,triggering smart contracts for modifying the order status,until the order is completed,and the payment is transferred.The results of performance and security tests on the platform show that the system runs smoothly,safely and reliably,and its comprehensive performance can meet the concurrent read and write needs of 5000 users.
