摘　　要：随着数据化、信息化时代的到来,保护敏感数据不被泄露成为人们关注的热点问题。信息安全愈显重要,对文件数据加密的需求也越来越大,与之对应的数据存储加密技术也愈来愈热。目前较为流行的存储加密方式有文件级加密、数据库加密、应用加密、介质加密、嵌入式加密设备。本文详细介绍了在文件系统级别上的两种数据存储加密技术eCryptFS和EncFS,并探究了它们的加密原理及存储加密过程,对比探究了这两种技术跨平台的可用性、操作性、是否支持增量备份以及密钥安全性等性能。hot issue. With the arrival of Information security data and becomes information age,the protection of sensitive data has become a more and more important;the demand for file data encryption is also growing.With the corresponding data storage encryption technology is also increasingly hot.The more popular storage encryption methods are file-level encryption,database encryption,application encryption,media encryption and embedded encryption device.In this paper,two kinds of data storage encryption technologies eCryptFS and EncFS at the file system level are introduced in detail.And then we explored the two encryption principle and storage encryption process,and compared the two technologies from the perspectives of cross-platform availability,operability,whether to support incremental backup and key security.
