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 ...

WebWe show that the problem of deciding whether a given Euclidean lattice L has an or-thonormal basis is in NP and co-NP. Since this is equivalent to saying that L is … 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 …
Webcentral in lattice-based cryptography), LIP is unlikely to be NP-hard. We note, though, that the reduction from the Graph Isomorphism Problem (GIP) [14] gives some evidence … WebWe 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. Our main result is an algorithm for this problem running in time n^ {O (n)} times a polynomial in the input size, where n is the rank of the input lattices.
