Title:
DATA ENCRYPTION METHOD, APPARATUS AND DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/258727
Kind Code:
A1
Abstract:
Disclosed are a data encryption method, apparatus and device, and a medium, which are used to solve the problems of a relatively high resource consumption and a relatively low efficiency during encryption and obfuscation processing of mass data. The method specifically comprises: acquiring a data set to be encrypted, and encrypting same to obtain a ciphertext data set; determining, according to a set manner, the amount of obfuscation corresponding to the ciphertext data set, and generating obfuscation parameters according to the amount of obfuscation, wherein the amount of obfuscation is less than the amount of ciphertext data in the ciphertext data set; and performing obfuscation processing on the ciphertext data set on the basis of each obfuscation parameter to obtain an obfuscated ciphertext data set. Therefore, a certain amount of obfuscation parameters are generated, and the ciphertext data set is subjected to the obfuscation processing according to each obfuscation parameter, so that the obtained obfuscated ciphertext data set is hard to crack; and furthermore, the number of the generated obfuscation parameters is relatively small, such that the data security is improved, the generation time of the obfuscation parameters is also saved on, and the data processing efficiency is improved.
