Abstract
본 발명은 갈로아필드 GF(2m)에서 승산을 수행하는 승산기에 관한 것으로, 소정 윈시다항식 p(x)를 이용하여 발생시킨 2m개의 m 비트데이티로 이루어진 갈로아필드 GF(2m)에 속하는 핑승수데이타 및 승수데이타를 승산하는 장치에 있어서, 상기 피승수데이타 및 상기 승수데이타를 승산규칙에 따라 비트별로 논리곱을 수행하는 m×m개의 논리곱수단들과, 상기 m×m개의 논리곱수단들의 출력들을 상기 원시다항식에 의거하여 선택적으로 입력하여 배타논리합하여 출력하는 m개의 배타논리합수단을 구비하여 피승수데이타 및 승수데이타가 인가되면 바로 승산데이타가 상기 m개의 배타논리합수단을 통하여 출력한다.The present invention relates to a multiplier for performing multiplication in gallofield GF ( 2m ), gallofield GF ( 2m ) consisting of 2 m mbit data generated using a predetermined wins polynomial p (x). An apparatus for multiplying multiplier data and multiplier data belonging to the apparatus, the multiplier data multiplying the multiplier data and the multiplier data by a bit according to a multiplication rule, and the m × m logical product Multiplier data are outputted through the m exclusive logic means as soon as multiplicative data and multiplier data are applied.
