Method and apparatus for performing electronic data file protection based on encrypted partition

Abstract

The present invention discloses a method and an apparatus for performing electronic data file protection based on an encrypted partition, and belongs to the field of electronic data file protection. The apparatus disclosed by the present invention adopts an overall design of ''a cloud server+a client''. The cloud server comprises a data acquisition module, a key storage module and a cloud identity authentication module. The client comprises a client identity authentication module, a transparent encryption module, a partition management module and a partition protection module. According to the method and apparatus disclosed by the present invention, ''a cloud server+a client'' dynamic authentication and transparent encryption / decryption are combined, so that files and folders can be effectively prevented from being freely accessed, duplicated or deleted by others, and the security of privacy data is ensured.

Description

technical field [0001] The invention relates to the protection of electronic data files, in particular to a method and device for protecting electronic data files based on encrypted partitions. Background technique [0002] Cloud storage: It is a new concept extended and developed on the concept of cloud computing. It is an emerging network storage technology. A large number of different types of storage devices work together through application software to jointly provide a system for data storage and business access functions. [0003] Advanced Encryption Standard (Advanced Encryption Standard, AES): It is a specification used by the National Institute of Standards and Technology for encrypting electronic data, and it is a new encryption algorithm that can be used to protect electronic data. Specifically, AES is an iterative, symmetric-key block cipher that can use 128-, 192-, and 256-bit keys, and encrypts and decrypts data in 128-bit (16-byte) blocks. Symmetric key cip...

AI Technical Summary

Problems solved by technology

[0007] 1. Only the folders and partitions where files are stored are encrypted, and the files themselves are not encrypted;

[0008] 2. Transparent encryption is not used, and users need to frequently perform encryption and decryption operations during use;

[0009] 3. The encrypted partition cannot be remotely managed, and verification cannot be performed after the leak;

[0010] 4. The security defense of the encrypted partition itself is weak, and the operation protection of the partition cannot be performed;

[0011] 5. Omissions in security management of partition encryption keys, which rely heavily on users' personal security awareness and memory;

[0012] 6. The software process is cumbersome and inconvenient to use
