Title:
DATA PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/047503
Kind Code:
A1
Abstract:
Disclosed are a data processing method and apparatus. The method comprises: acquiring multiple target parameters of a byte to be encrypted; performing a first logic operation on the multiple target parameters and the byte to be encrypted to obtain a first intermediate encryption result; according to a current position of each bit in the first intermediate encryption result, reallocating the position of each bit; performing a shift operation to a first direction on the first intermediate encryption result after the reallocation of the position to obtain a second intermediate encryption result; and performing a second logic operation on the multiple target parameters and the second intermediate encryption result to obtain an encryption result of the byte to be encrypted. The present invention solves the technical problem in the prior art that computational resources are wasted due to the relatively large computational amount of an encryption algorithm for data of a short length.
