Data set encryption pre-processing method

Abstract

The invention discloses a data set encryption preprocessing method, which belongs to the field of information encryption. The invention first counts the total amount of elements in the data set, then calculates the number of rounds that the data set needs to be encrypted, and finally groups each data element in the data set; through By processing the data before encryption, the invention makes the encryption of a large amount of data sets more efficient and safe, is suitable for large-scale data sets of any structure, and can save later encryption time.

Description

technical field [0001] The invention belongs to the field of information encryption, in particular to a data set encryption preprocessing method. Background technique [0002] With the development of cloud computing, the amount of data generated and processed by the Internet is increasing day by day. Big data almost runs through the entire real world. However, while enjoying the convenience brought by big data, the privacy of personal data and the security of enterprise data are also getting more and more attention. Cryptography is an effective means to prevent data from being illegally tampered with and eavesdropped. However, the security of applying existing cryptographic standards directly to the encryption of large-scale data sets has not yet been fully proved. For example, images encrypted with the AES algorithm may leak some information, so improper use of existing encryption algorithms cannot ensure data security. [0003] An important requirement of the encryption ...

Problems solved by technology

However, the applicability of this algorithm is too narrow, it is only suitable for image encryption and requires the pixel size of the image to be 2 a ×2 a , a is a positive integer, not suitable for a large number of data sets with arbitrary structures

And currently there is no standard encryption algorithm suitable for large-scale data sets
