Lattice-reduction
WebIn mathematics, the goal of lattice basis reduction is to find a basis with short, nearly orthogonal vectors when given an integer lattice basis as input. This is realized using different algorithms, whose running time is usually at least exponential in the dimension of the lattice. Contents 1 Nearly orthogonal 2 In two dimensions 3 Applications WebGiven a basis Bof L, the goal of a lattice reduction algorithm is to nd a better basis, ideally formed by short and nearly orthogonal vectors, which has numerous applications in …

Webq-ary codes, it is important to also consider the non-reduced value of x 2Zm to have a notion of Euclidean length. Exercise 1 Show that there is a one-to-one correspondence between q-ary lattices L of dimension m and subgroups of Zm q. The following (q-ary) lattice bears the name ‘parity check lattice’, a name descending from coding-theory. WebTools. The Lenstra–Lenstra–Lovász (LLL) lattice basis reduction algorithm is a polynomial time lattice reduction algorithm invented by Arjen Lenstra, Hendrik Lenstra and László Lovász in 1982. [1] Given a basis with n -dimensional integer coordinates, for a lattice L (a discrete subgroup of Rn) with , the LLL algorithm calculates an LLL ...
