Embodiment Construction

[0093] Such as Figure 1-5 As shown, the information dispersion method based on the security of the distributed object storage system provided by the present invention is described in detail as follows:

[0094] In order to improve the calculation efficiency of the algorithm while solving the security loopholes in the AONT-RS series algorithm, the invention improves the AONT algorithm and combines the NZZD code to propose a safe and efficient information dispersion algorithm AONT-NZZD that supports data deduplication .

[0095] The AONT-NZZD algorithm draws on the ideas of the SAONT-RS algorithm, and uses the method of verifying the hash value of the data block to ensure the recoverability of the original data. The difference is that the AONT-NZZD algorithm calculates the hash value of the data block by adding salt The way to resist the collision attack of the hash function further enhances the confidentiality of the data. In order to improve the computational efficiency of ...

Abstract

The invention is applicable to the field of data information distribution technology improvement, and provides an information dispersion method based on distributed object storage system security, which comprises the following steps: S1, calculating a data block hash value in a salting manner to resist collision attack of a hash function and improve the confidentiality of data; S2, improving the calculation efficiency by using an SHA2512 hash algorithm, and replacing the random key with the hash value of the original data; S3, inputting the data with the same content, and encoding the data through an AONTNZZD algorithm to generate data blocks with the same content so as to realize data deduplication. According to the AONTNZZD algorithm, the length of a data block is additionally selected as a salt value of hash operation when the hash value of the data block is calculated, and therefore an attacker can be prevented from carrying out hash function attack. According to the AONTNZZD algorithm, an NZZD code based on binary shift and exclusive-OR operation is adopted, and the relatively good encoding and decoding rate is achieved.

Description

technical field [0001] The invention belongs to the technical improvement field of data information distribution, and in particular relates to an information dispersal method and system based on the security of a distributed object storage system. Background technique [0002] Today, with the rapid development of the global economy and continuous technological innovation, information industries such as cloud computing and the Internet of Things are booming, and the global data volume and storage scale are growing exponentially. With the advent of the era of big data, in order to alleviate the cost pressure of local data storage and maintenance, more and more individuals and organizations migrate data from local to cloud storage platforms provided by cloud service providers. [0003] Among the growing Internet data, the growth of unstructured data is particularly significant. Unstructured data contains huge potential value, but it has not been fully utilized and tapped becau...
