为解决传统文件共享方式单一、安全性不足以及共享文件权限控制自主性过高的问题,提出了一种文件加密存储分级访问控制方案,通过在系统中增加分级管理单元,实现对用户、文件的分级以及用户对文件访问权限的控制,实现文件的访问范围可控;通过文件的加密实现文件存储和传输的安全性;分级密钥的使用,简化了密钥的存储。服务器端文件的加解密操作通过专门的密码卡实现,减轻了服务器端的工作量,加速了文件的加解密处理。在基于PC和Zynq平台上进行了验证,实现了预定功能。
The traditional file sharing way is single
lack of security
and the shared file's permission autonomous control is too high.To solve these problems
a file encrypted storage and hierarchical access control scheme was proposed.Through increasing classification management unit in the system
classification of users and documents
users of file access control were achieved
the scope of file access control was realized.Security of file storage and transmission was realized through encryption
the key storage was simplified using hierarchical key.Server file en-cryption and decryption operations were achieved through a special password card
which reduced the server work-load and accelerated the file encryption and decryption processing.The scheme was verified on PC and Zynq plat-form
and the predetermined function was realized.
