摘要

PROBLEM TO BE SOLVED: To provide a prime factor extraction method and a device which have excellent computation efficiency.;SOLUTION: The method is characterized in that: small prime numbers Li and natural numbers ei are prepared so that the product of the prime numbers raisde to (Liei)th power exceeds 2u; Li is selected by further making (r) and Li relatively prime on condition that r and Li-1 are mutually prime and ei≥2 and outputting Li when one Li is exactly divisible; such a minimum natural number ki that s×ki is exactly divisible by λ (Liei) when N is not exactly divisible by all Li's is found when N is not exactly divisible by all the Li's; ki roots Ai, j of ki different Nki modulo Liei are all regarded as candidates for Pr (mod Liei); one (j) is selected for all the (i)'s; candidates for Pr module the product M of Li's are found among (m) Ai, j (mod Liei) given by those (i)'s and (j) by using Chinese residue theorem; and r-1 mod ϕ (M) is found.;COPYRIGHT: (C)2003,JPO
