Title: Prime number deciding device, method and program
Inventor: KOIKE MASANOBU
IPC: G09C1/00
Filed: 2001-03-13
Abstract: PROBLEM TO BE SOLVED: To make it difficult to analyze an integer n from power analysis and timing analysis at the time of the prime number deciding of a positive integer n. SOLUTION: At the time of the prime number decision of a prime number candidate n, the prime number judgment is performed for m=nαfor which n is multiplied with the integer α which can not be divided by any prime number equal to or less than n1/2 without using the prime number candidate n itself. Thus, when the integer αis kept secret, it becomes difficult to obtain the information of n from m. Thus, at the time of the prime number decision, it is made difficult to analyze the prime number candidate n from the power consumption waveform or processing time of an arithmetic operation.
