Paper 2023/1288 , SandboxAQ , SandboxAQ , SandboxAQ , SandboxAQ Most of the current lattice-based cryptosystems rely on finding Gaussian Samples from a lattice that are close to a given target. To that end, two popular distributions have been historically defined and studied: the Rounded Gaussian distribution and the Discrete Gaussian distribution. The first one is nearly trivial to sample: simply round the coordinates of continuous Gaussian samples to their nearest integer.
