Title:
MASS ENCRYPTION MATRIX CALCULATION-OPTIMIZATION PROCESSING METHOD IN POWER DEVICE ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2020/027386
Kind Code:
A1
Abstract:
The present invention may provide a method for optimization-processing mass encryption matrix calculation by performing matrix multiplication and vector addition in parallel by using a transposed matrix. Specifically, the matrix calculation-optimization processing method may comprise the steps of: identifying a first matrix and a second matrix multiplied by the first matrix; determining a transposed matrix of the second matrix on the basis of vector interleaving; and performing a multiplication operation between the first matrix and the transposed matrix of the second matrix and performing an addition operation on a result of the multiplication operation and a third matrix.
