WebThe hardness of the NTRU and Ring-LWE problem directly depends on the degree of the polynomial f(X). Based on the current state of knowledge, obtaining 128-256 bit hardness requires taking dimensions somewhere between 512 and 1024.

First, we adapt the line of proof of Brakerski and Döttling on R-LWE (TCC’20) to prove that the existence of certain distributions implies the entropic hardness of M-LWE. Then, we provide one such distribution whose required properties rely on the hardness of the decisional Module …
