基于过滤驱动的文件保护系统

数据的安全保护是当前网络安全领域研究的热点,本文提出了一种基于文件系统过滤驱动的文件保护系统。该文件保护系统在操作系统内核状态下实现了对文件的透明加/解密,并提供了访问控制、密钥管理等功能。加/解密算法可以灵活采用并且不公开,提高了加密的有效性。文件以密文的形式保存,且只能被合法用户以非常安全的方式访问。用户使用起来非常方便,只需提供自己的私钥即可。

System of Files Protection Based on Filter Driver

Currently data security protection being the hot topic of the field of network security,a system of files protection based on file system filter driver is thus proposed.It is under operating system kernel mode that files are encrypted and decrypted and is transparent to users,and meanwhile access control and key management are provided.File encryption and decryption algorithm can be secret and introduced flexibly,thus ensuring the efficiency of encryption.The system is convenient for users because files are...
