Abstract

An important component ofthe index calculus methods for finding discrete logarithms isthe acquisition of smooth polynomial relations. Gordon and McCurley(1992) developed a sieve to aid in finding smooth Coppersmithpolynomials for use in the index calculus method. We discusstheir approach and some of the difficulties they found with theirsieve. We present a new sieving method that can be applied toany affine subspace of polynomials over a finite field.
