摘要
文章在对现代密码学技术研究的基础上,结合硬件指纹技术的特点,提出了一种新的混合加密文件保护系统。为了保护用户信息未经授权的加密和解密,提取U盘具体信息的MD5值作为硬件指纹;在进行信息加密时,采用了3DES对称加密技术,同时使用了RSA非对称算法对3DES密钥进行了二次加密,提高了安全性。最后,为了防止U盘和密码的丢失,增加了管理员权限,实现了自动解密功能。
Based on the research of modern cryptography technology and the characteristics of hardware fingerprint technology,this paper proposes a new hybrid encryption file system.To preventunauthorized encryption or decryption,the MD5 value of the specific information of the USBflash disk is extracted as a hardware fingerprint.During theencrypting of files,Triple-DEScryptography algorithm is used,and the Triple-DES keys is encrypted by the RSA cryptography algorithm to enhance the security.Finally,in order to prevent the loss of the USBflash diskor password,the administrator role is added to realize the automatic decryption.
