Web1 de mar. de 2024 · In this section, we explore two possible methods to solve the finite field isomorphism problem. Such an isomorphism will be described as an n-by-n matrix M. The first approach is based on lattice reduction. The second approach is a highly non-linear attack of unknown but, we believe, high difficulty. 2.4.1 Lattice Attack of (\(\dim \approx … 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).

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 ... 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.
