摘要: 采用保留格式加密技术加密航班信息、旅客信息、客票信息等民航信息系统数据,选取简单、有效的FF1算法和FF3算法以及更为灵活的混合格式加密算法IFX,采取高位偏移、变长格式、数值间接映射、以数据库的id号为随机因子等策略优化扩展算法功能。在保证信息安全性、完整性和真实性的同时,保留民航信息系统数据的内在格式,支持在不解密数据的条件下实现对数据的统计分析,降低数据泄露的风险。

关键词: 保留格式加密, 航班信息加密, 混合格式加密算法

Abstract: The usage of format-preserving encryption technology in the encryption of flight information,passenger information and ticket information was studied by choosing simple and effective algorithms such as FF1 algorithm,FF3 algorithm and a more flexible hybrid format encryption algorithm IFX.The functions of high bit offset,forward expansion,numerical indirect mapping,and using ID of database as random factors are used to optimize the function of the extended algorithm.While ensuring security,integrity and authenticity of the information,the internal format of flight data is kept,and the statistical analysis of civil aviation information is implemented without decryption,so as to reduce the risk of data leakage.

Key words: Flight information encryption, Format-preserving encryption, IFX
