Possible Prime Modified Fermat Factorization: New Improved Integer Factorization to Decrease Computation Time for Breaking RSA

Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 265)

Abstract

The aim of this research is to propose a new modified integer factorization algorithm, called Possible Prime Modified Fermat Factorization (P2MFF), for breaking RSA which the security is based upon integer factorization. P2MFF is improved from Modified Fermat Factorization (MFF) and Modified Fermat Factorization Version 2 (MFFV2). The key concept of this algorithm is to reduce iterations of computation. The value of larger number in P2MFF is increased more than one in each iteration of the computation, it is usually increased by only one in MFF and MFFV2. Moreover, this method can decrease the number of times in order to compute the square root of some integers whenever we can strongly confirm that square root of these integers is not an integer by using number theory. The experimental results show that P2MFF can factor the modulus faster than MFF and MFFV2.
