Deciding whether a Lattice has an Orthonormal Basis is in co-NP

WebAs a result, just like many other lattice problems (e.g., the problem of approximating the length of a shortest nonzero vector to within polynomial factors, which is central in lattice-based cryptography), LIPis unlikely to be NP-hard. We note, though, that the reduction … WebAbstract We study the Lattice Isomorphism Problem (LIP), in which given two lattices L 1 and L 2 the goal is to decide whether there exists an orthogonal linear transformation mapping L 1 to L 2 .

WebThe RSLP can be seen as a special case of the Lattice Isomorphism Problem, which, given two lattices Λ1,Λ2, asks whether there is an isomorphismϕ: Λ1→ Λ2between the two lattices that preserves the Euclidean structure (hx,yi = hϕ(x),ϕ(y)i). That is, hx,yi = Pn i=1xiyifor x,y∈ Rn.
