4.加密算法(Encryption Algorithm) 定义:加密算法是将明文数据转换为密文的数学过程,目的是保护数据的机密性。加密算法使用一个或多个密钥来加密和解密数据。 常见算法: 对称加密算法:加密和解密使用相同的密钥,如 AES(Advanced Encryption Standard)和 DES(Data Encryption Standard)。 非对称加密算法:加密和解密使用不...

1 目前支持EFS加密的Windows操作系统主要有Windows2000全部版本和Professional、WindowsVistaBusiness或更高以及Professional或更高版系列的操作系统,所有家庭版和入门版的Windows都不支持该功能。其次,EFS加密只对NTFS分区上的数据有效(注意,这里我们指的是NTFS3.1分区,有时也称作NTFS5.0(指随同Windows2000发布,win...
EFS 加密是基于公钥策略的。在使用EFS加密一个文件或文件夹时,系统首先会生成一个由伪随机数组成的FEK(File Encryption Key,文件加密钥匙),然后将利用FEK和数据扩展标准X算法创建加密后的文件,并把它存储到硬盘上,同时删除未加密的原始文件。随后系统利用你的公钥加密FEK,并把加密后的FEK存储在同一...
EFS 将对称加密算法和非对称加密算法结合起来保护文件:文件数据使用对称加密算法(默认128位的DESX,也可用168位的3DES)加密,在该过程中使用的密匙叫做文件加密密匙(File Encryption Key, FEK),由系统生成;FEK又使用非对称加密算法(1024位的RSA)加密,这需要一个有私钥的证书,由用户提供;加密后的数据和FEK将一...
