摘要
传统加密软件在实际应用中一般要求用户在使用前手动解密文件,使用结束后再手动加密文件,整个过程十分繁琐,且文件在操作过程中以明文形式存储在硬盘上,存在安全隐患。该文针对传统加密软件的不足,采用过滤驱动技术,设计一个透明加密的文件系统模型,并予以实现。该模型无需用户改变使用习惯,全程实时透明加密数据,有效保障了数据的安全性,提高了工作效率,改善了用户体验。
In traditional encryption software, the documents have to be decrypted manually before being used, and encrypted manually after being used. It is cumbersome. During this operation, the documents exist as clear texts and are stored on hard drive, which has hidden risks of security. In view of the traditional encryption software insufficiency, this paper designs and realizes a transparent encryption file system model using filter driver technology. This system can real-time transparently encrypt data in the entire process without changing the user habit, effectively protect the data security, significantly raise the work efficiency and greatly improve the user experience.
