摘　　要：隐私保护是航空运输领域的一项重要安全问题。航空出行中的商务消费极易暴露交易各方的隐私,为降低航空商务消费中的隐私泄露风险,提出一种面向航空公务消费数据的隐私保护结算方案,运用密码学技术,创新性地将双公钥加密机制融入联盟链系统。一方面通过联盟链机制简化航空公务出行人员的消费结算流程,优化了航空出行体验;另一方面通过在密文中额外添加一个接收方公钥,使得航空公司和航空企业客户作为收、付款方可以独立解密并获得相同的消费信息。实验对比分析表明,方案不仅实现了航空旅客及其所属企业的隐私保护需求,还保障了航空公司和企业客户对消费数据的精准审核与结算,满足了交易三方的安全与效率需求,具有较强的应用价值。Privacy preservation is an important security issue in the field of air transportation.Business consumption in air travel can easily expose the privacy of all parties involved in the transaction.In order to reduce the risk of privacy leakage,our paper proposes a privacy preservation settlement scheme for aviation business consumption data.It innovatively integrates the double public key encryption mechanism into the consortium blockchain system by using cryptography technology.On the one hand,through the consortium blockchain system,the process of consumption and settlement for air travelers is simplified and their air travel experience is optimized.On the other hand,an additional receiver′s public key is added to the ciphertext,so the airline and its enterprise customer can independently decrypt and obtain the same consumption information.Experimental analysis shows that not only our scheme realizes the privacy preservation for air passengers and enterprise customers,but also ensures the precise audit of consumption data between airlines and their enterprise customers.It meets the security and efficiency requirements of three transaction parties,and has prospect application future in the field of air transportation.
