Abstract
A circuit design method able to design a processing circuit for processing a finite field with fewer circuit design elements and in a smaller-size than the past comprising obtaining a first primitive root αon the basis of a first polynomial for a first extension from a first finite field to a second finite field, obtaining a second primitive root αon the basis of a second polynomial for a second extension from the second finite field to a third finite field, wherein a coefficient of a 0-th term is defined using the first primitive root αobtained above and the coefficient of the-th term of the first polynomial, defining processing on the third finite field using a base expressed using the second primitive root α, and designing the processing circuit for performing that processing.
