Embodiment Construction

[0026] In terms of specific implementation, in order to conveniently generate different heterogeneous file systems, the SeFS file system and corresponding transformation tools are implemented, such as figure 2 shown. The conversion tool includes a compilation tool and a construction tool. The compilation tool is used to dynamically generate a specific file access interface in combination with SeFS, and the construction tool is used to construct a SeFS file system instance in a random format when the file system is initially constructed. In a multi-user scenario, a private SeFS file system instance is generated for each user through a transformation tool, and has a proprietary format and a dedicated file interface, ensuring the security of user data.

Abstract

The invention belongs to the technical field of computer file systems, in particular to a method for constructing a secure file system. The present invention realizes the heterogeneity of the file system through multi-dimensional data space transformation, and provides file systems with different structures for users authorized to use the file system. They have the same business processing logic, and there is no difference in logic. Different data structures, organizations, processing, and storage methods are brought about by different data structures, thereby realizing the heterogeneity of file system data organization and access, and enhancing file system security; file systems mainly include file interfaces that provide user access and file system metadata. , file metadata and data space management; a random heterogeneous transformation method is designed for the four parts, so that the file system built each time is random, different from ordinary file systems, the format is fixed, and it is easy to know the organization of the file system through analysis. Ensure file system security.

Description

technical field [0001] The invention belongs to the technical field of computer file systems, and in particular relates to a method for constructing a secure file system. Background technique [0002] Since the appearance of the file system, it has always been a powerful tool for managing organizational data and providing users with friendly interface support. Today, with such a large amount of data, the file system that shoulders the responsibility of data organization management and safe storage is even more important. Important position. [0003] Security is the primary factor to ensure the availability of the file system. In the process of continuous development, the following factors make the security of the file system very important. First, in today’s society, most of the world’s data is managed and organized through the file system. Various private data, confidential data, etc. File system security poses enormous challenges. [0004] There are two main types of fi...
