On the lattice isomorphism problem
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. http://www2.mta.ac.il/~ishayhav/papers/latticeiso.pdf

WebAbstract We study the Lattice Isomorphism Problem (LIP), in which given two lattices ℒ1 and ℒ2 the goal is to decide whether there exists an orthogonal linear transformation mapping L1 to ℒ2. Our main result is an algorithm for this problem running in time nO(n) times a polynomial in the input size, where n is the rank of the input lattices.

Web1 de jan. de 2014 · Haviv and Regev, in , study the lattice isomorphism problem under orthogonal transformations. In the process, they develop a general isolation lemma which they apply to lattice isomorphism and give a \(O^*(k^{O(k)})\) time algorithm for checking if two rank-\(k\) lattices are isomorphic under orthogonal transformations.

WebThe lattice isomorphism problem (LIP) asks one to find an isometry between two lattices. It has recently been proposed as a foundation for cryptography in two independant works [Ducas & van Worden, EUROCRYPT 2024, Bennett et al. preprint 2024]. This problem is the lattice variant of the code equivalence problem, where the notion of the hull of ...
