e/Lattice problem

Information
has gloss	eng: In computer science, lattice problems are a class of optimization problems on lattices. The conjectured intractability of such problems is central to construction of secure lattice-based cryptosystems. For applications in such cryptosystems, lattices over vector spaces (often \mathbbQ}^n) or free modules (often \mathbbZ}^n) are generally considered.
