Abstract
본 논운에서는 LFSR 구조를 개선하여 기존의 LFSR 구조 보다 면적과 속도면에서 효율적인 새로운 구조의 유한체 승산기를 제안한다. 기존의 LFSR 구조에서는 t 배 속도를 개선하기 위하여 레지스터의 수를 txm 만큼의 레지 스터수가 증가하였다. 그러나 , 본 논문에서는 레지스터의 수를 증가하지 않고 속도를 개선하는 구조를 이용하여 직렬 유한체 승산기를 설계하였다 . 설계된 회로는 SYNOPSYS 시뮬레이션을 이용하여 LFSR 구조에 비하여 2 배 속도가 개선된 성능을 검증하였으며 또한 , 본 논문의 고속 , 저면적 승산기는 스마트카드와 같은 휴대형 단말기의 암호처리장치에 효과적으로 사용될 수 있음이 검증되었다 .
