加密文件系统中缓冲技术的研究

Research of Buffering Technique in the Encrypting File System

文章对加密文件系统中缓冲的清除技术进行了研究。当加密文件关闭时,调取内核函数,采用对其缓冲中的明文数据进行清除并非禁用的方法,从而既保障了加密文件系统对文件操作的效率,又保证了文件内容安全,能有效防止文件内容泄密。

The article studies the removal technology of buffer in Encrpting File System. When the encrypted files are closed, the kernel function is used and plaintext data is deleted rather than forbidden. The method ensures the efficiency of file operations and document content security in encrypted file system so as to effectively prevent the document disclosure.
