On the lattice isomorphism problem
WebI will then discuss some general negative results, some positive examples and some open problems about when it is possible to ``move'' from one of these classes to another one by means of functoriality.

Web1 /14 Motivation •LWE, SIS, NTRU lattices:versatile, butpoor decoding. •Many wonderful lattices exist with great geometric properties. •Can we use these in cryptography? …

WebG = UGUT, so another appropriate name for this problem is the Decisional lattice conjugacy problem. Note that the lattice isomorphism problem is much easier when given integral bases: the lattices are isomorphic if and only if they have the same Hermite Normal Form (HNF). Hypercubic Lattice Case: This paper focuses on hypercubic … Web6 de fev. de 2009 · We prove that the related problem of counting vertices of the Voronoi cell is #P-hard. As a byproduct of our construction, we show that the lattice isomorphism problem is at least as difficult as the graph isomorphism problem. We turn to practical algorithms for the covering radius problem in Section 3.

I.e., what is the minimal distortion of a linear bijection between the two lattices? LDP generalizes the Lattice Isomorphism Problem (the lattice analogue of Graph Isomorphism), which simply asks whether the minimal distortion is one.
