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 … 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.

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 . 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.
