Montgomery's method of polynomial selection for the number field sieve
The number field sieve is the most efficient known algorithm for factoring large integers that are free of small prime factors. For the polynomial selection stage of the algorithm, Montgomery proposed a method of generating polynomials which relies on the construction of small modular geometric progressions. Montgomery’s method is analysed in this paper and the existence of suitable geometric p...
متن کاملOn polynomial selection for the general number field sieve
The general number field sieve (GNFS) is the asymptotically fastest algorithm for factoring large integers. Its runtime depends on a good choice of a polynomial pair. In this article we present an improvement of the polynomial selection method of Montgomery and Murphy which has been used in recent GNFS records. 1. The polynomial selection method of Montgomery and Murphy In this section we brief...
متن کاملNon-linear polynomial selection for the number field sieve
We present an algorithm to find two non-linear polynomials for the Number Field Sieve integer factorization method. This algorithm extends Montgomery’s “two quadratics” method; for degree 3, it gives two skewed polynomials with resultant O(N5/4), which improves on Williams O(N4/3) result [12].
متن کاملA General Polynomial Selection Method and New Asymptotic Complexities for the Tower Number Field Sieve Algorithm
In a recent work, Kim and Barbulescu had extended the tower number field sieve algorithm to obtain improved asymptotic complexities in the medium prime case for the discrete logarithm problem on Fpn where n is not a prime power. Their method does not work when n is a composite prime power. For this case, we obtain new asymptotic complexities, e.g., Lpn(1/3, (64/9) ) (resp. Lpn(1/3, 1.88) for th...
متن کاملTower Number Field Sieve Variant of a Recent Polynomial Selection Method
At Asiacrypt 2015, Barbulescu et al. performed a thorough analysis of the tower number field sieve (TNFS) variant of the number field sieve algorithm. More recently, Kim and Barbulescu combined the TNFS variant with several polynomial selection methods including the Generalised Joux-Lercier method and the Conjugation method proposed by Barbulescu et al. at Eurocrypt 2015. Sarkar and Singh (Euro...
