Implementation of Learning with Errors in Non-Commuting Multiplicative Groups
Abstract
In this paper, we demonstrate a way to generalize learning with errors (LWE) to the family of so-called modular-maximal cyclic groups which are non-commuting. Since the group $\mathbb{M}_{2^t}$ has two cycles of maximal multiplicative order, we use this fact to construct an accurate criterion for restoring the message bit with overwhelming probability. Furthermore, we implement the original idea by O. Regev in the considered group to gain benefits from the non-commutativity of $\mathbb{M}_{2^t}$. Also we prove that using this approach we can achieve a level of security comparable to the original idea.
