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 … 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 …

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.

As a byproduct of our construction, we show that the lattice isomorphism problem is at least as difficult as the graph isomorphism problem. We turn to practical algorithms for the covering radius problem in Section 3.
WebOn the isomorphism problem of concept algebras 227 Usually we will write a closure operator on a set X to mean a closure operator on the powerset (P(X),⊆) of X.Dually, f is a kernel operator on P if x ≥ f(y) ⇐⇒ f(x) ≥ f(y), for all x,y ∈ P. As above, we say that f is a kernel operator on X to mean a kernel operator on (P(X),⊆). For a weakly …
