为了解决电子数据存储和交换的安全问题，本文提出了EncryptingShareBox(ESB)技术。ESB作为服务器上的基本加密实体，能提供透明的数据加密存储，并支持用户间灵活的加密数据共享。此外，还介绍了针对KylinServer的EncryptingFileSystem(KSEFS)软件架构。经评估，与常规文件服务相比，该系统的性能仅下降了3%到18%。
摘要：
To solve the security problem in electronic data storage and exchange, this paper presents the technology of Encrypting Share Box (ESB). ESB is the basic encryption entity on the server, which can not only provide transparent data encryption storage, but also support a flexible encrypting data sharing among users. We also put forward a software architecture for the Kylin Serveroriented Encrypting File System (KSEFS). At the end of the paper, we evaluate the file system, and the results show that, compared with the normal file services, the performance is reduced only by 3% to 18%.
