암호학의 암호 생성과 해독, 소수판별법의 성능은 대부분 $a^b$(mod n)의 모듈러 지수연산의 효율적 구현여부로 결정된다. 모듈러 지수연산법에는 표준 이진법이 최선의 선택으로 알려져 있다. 그러나 큰 자리수의 b에 대해서는 d-ary, (d=2,3,4,5,6)이 보다 효율적으로 적용된다. 본 논문에서는 $b{equiv}0$(mod m), $2{leq}m{leq}16$인 경우 b를 m-진법으로 변환시켜 수행하는 방법과 m-진법 수행과정에서 결과 값이 1 또는 a가 발생하는 경우 곱셈 수행횟수를 획기적으로 줄이는 방법을 제안하였다. -
