Abstract
Official abstract text for this publication.
Distributed processing system and method for discrete logarithm calculation. The speed and resource efficiency of discrete logarithm calculation may be improved by allowing a plurality of operation agents to distributively process an operation of generating a modulo multiplication auxiliary table, an operation of generating a pre-calculation table, and an operation of searching for an answer by applying an iterated function for discrete logarithm calculation in a discrete logarithm calculation operation using the pre-calculation table.
First claim
Opening claim text (preview).
What is claimed is: 1. A distributed processing method for discrete logarithm calculation, the method comprising: setting, by a main operation controller, p-1 and q-1 of a cyclic group having N=pq (p and q are prime numbers) as a modulo, as multiples of a predefined number of prime factors having sizes of B-smooth numbers and a predefined number of prime factors having sizes equal to or less than B/2-smooth numbers; allocating, by the main operation controller, a number of prime…
