基于虚拟文件系统的安全存储技术的研究

Secure Storage Technology Based on Virtual File System

介绍了一种基于虚拟文件系统的加密存储方法.通过文件系统开发技术设计并实现一个虚拟文件系统,该文件系统能够将一个二进制文件映射成虚拟磁盘,而且可以在虚拟磁盘上存取数据.为了保证虚拟磁盘中的文件的安全性,还在虚拟文件系统上集成了加密引擎、密钥管理和硬件绑定等模块.这种安全存储技术操作简单,并且能够提供高效实时的加密/解密措施,具有一定的实用价值.

This paper describes an encrypted storage method based on the virtual file system. We design and implement a virtual file system through the file system development technology. Virtual file system regards a binary file as virtual disk, and can access the data on the virtual disk. In order to ensure the security of the file in virtual disk, we integrate encryption engine, key management and hardware binding modules into virtual file system. This security storage technology is easy to use, and can provide efficient real--time encryption / decryption measures, so it has practical value.
