Title:
PARALLEL FINITE FIELD MULTIPLICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/121149
Kind Code:
A1
Abstract:
A parallel finite field multiplication device, comprising M cascaded logic processing modules; a first input end of a first logic processing module receives a first operand; a second input end of the first logic processing module receives a zero value; a third input end of the first logic processing module receives a 0th bit of a second operand; a first input end of an mth logic processing module is connected to a first output end of an m-1th logic processing module; a second input end of the mth logic processing module is connected to a second output end of the m-1th logic processing module; a third input end of the mth logic processing module receives an m-1th bit of the second operand; and a fourth input end of each logic processing module forms a parallel connection together and receives a third operand. In the parallel finite field multiplication device, M cascaded logic processing modules may be used, according to different numbers of the cascaded logic processing modules, in finite field multiplication of different lengths, without needing to carry out polynomial multiplication.
