摘　　要：为了解决航空机票销售过程中某些机票代理商或旅客恶意“虚占座位”的问题,提出了一种基于改进PoA(proof of authority)共识机制的区块链系统方案。该方案使用联盟区块链作为各航空公司之间的沟通平台;采用信用积分、动态分级,形成新的PoA共识机制;使用哈希算法保护旅客的隐私信息;依靠智能合约实现航空公司数字身份信息的存储、旅客身份注册、旅客订票信息的存储和共享。原型系统试运行表明,该系统可以及时发现并有效制止虚占座位行为。经分析评估得出,该方案具有保护隐私、去中心化、高安全性的特点,为解决民航领域存在已久的虚占座位问题提供了新的借鉴思路。In order to solve the issue of malicious phonily occupying seats for some ticket agents or passengers in the process of air ticket sales,this paper proposed a blockchain system scheme based on the improved PoA consensus mechanism.The scheme used the alliance blockchain as a communication platform among airlines,adopted credit points and dynamic grading to build a new PoA consensus mechanism,protected passengers’private information with hash algorithm,and achieved digital storage of ID information,registration of passengers,storage and sharing of passenger booking information for airline corporations relying on smart contracts.The prototype system trial operation shows that the system can timely detect and effectively stop the phonily occupying seats behavior.After analysis and evaluation,the program has the characteristics of privacy protection,decentralization and high security,and provides a new reference to solve the long-standing problem of phonily occupying seats in the civil aviation field.
