摘要
访问权限管理和数据加密是实现计算机数据安全的主要技术手段。然而,以往计算机数据安全技术往往孤立的采用二者之一,安全性较低、应用复杂。本文介绍了EFS加密技术基本原理,并将“EFS文件加密技术”充分与计算机操作系统的权限管理机制结合,利用RSA等成熟的加密算法对密钥和数据进行加密,极大的提高了计算机数据的安全性。
The main technical measures to keep computer data safe are user access management and data encryption. Previous computer data security technology often used one of them separately,it made relatively low security and complex usage. It introduces basic theory of EFS and combines ＂Encrypting File System （EFS）＂ with the user access management principle of computer operating system closely, and encrypts data and key with some mature encrypting algorithm like RSA. It has improved the security of computer data obviously.
