Symmetric-group Regularity in the Distribution of Minima of Positive Quadratic Forms Reduced By Korkin-Zolotarev

M.A. Lyalin


Creation of cryptographic systems based on lattice theory is a promising direction of postquantum cryptography. The purpose of this work is to obtain new properties of lattices and related objects. As a result, a regularity in the distribution of the minima of positive quadratic forms, reduced by Korkin-Zolotaryov, was revealed. Their correspondence to the heights of fundamental parallelepipeds of n-dimensional lattices has been established. The obtained result is of practical importance in the construction of dense lattice packs of balls, in solving problems of the lattice theory, researching of Hermit’s constant. The result should be taken into account when creating new cryptographic systems based on lattice theory
