Embodiment Construction

[0016] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0017] figure 1 It is a schematic structural diagram of an encryption and decryption system for a disk data storage area provided by an embodiment of the present invention. Such as figure 1 As shown, the system includes an encryption sector initialization module 112 , an encryption algorithm configuration module 118 and a data encryption and decryption module 119 .

[0018] The encrypted sector initialization module 112 determines the boundaries of encrypted sector locations according to the capacity of the disk partition and the characteristics of the file system.

[0019] Preferably, when the disk has super block (super block) information, the first calculation method is used to determine the position of the data block sector, and the data block sector on the disk is combined with the boot sector of the disk and th...

Abstract

The invention relates to an encryption and decryption method and system capable of aiming at a disk data memory area. The system comprises an encryption algorithm configuration module (118), an encryption sector initialization module (112) and a data encryption and decryption module (119), wherein the encryption sector initialization module (112) is used for setting a sector which needs to be encrypted and decrypted according to the partitioned memory capacity of a disk and file system characteristics; the encryption algorithm configuration module (118) is used for setting an encryption algorithm used by the system; and the data encryption and decryption module (119) is used for encrypting file data written into the disk data memory area according to the encryption algorithm and carrying out decryption on the file data read via the disk data memory area. By use of the system, decryption and encryption processing for the disk data memory area is realized, but the boot sector of the disk and the super block sector and the file information sector of the disk file system are not subjected to the encryption and decryption processing, and an efficient disk encryption and decryption frame is realized.

Description

technical field [0001] The invention relates to the technical field of disk data encryption and decryption, in particular to an encryption and decryption method and system for a disk data storage area. Background technique [0002] With the rapid development of Internet technology and the continuous enrichment of network applications, the data generated in the network is growing explosively, and the types of data are various, which brings great challenges to data management and analysis. Therefore, the research on massive data has gradually matured, and the concept of big data has been proposed. Big data has four notable characteristics, that is, huge data volume, rich data structure, fast growth rate and low value density. Therefore, it is necessary to use targeted solutions to deal with big data. Since the security mechanism is the basic problem of massive data storage, Therefore, the security mechanism will become an urgent problem to be solved in big data processing, an...
