Webapplications of lattice basis reduction to algorithmic number theory has been included; in many cases, the main point consists of recognizing a lattice behind a problem. For applications to integer programming, one may consult [Aardal and Eisenbrand 2005]. Complete proofs have not been provided for all results mentioned, though Lattice-based cryptography is the generic term for constructions of cryptographic primitives that involve lattices, either in the construction itself or in the security proof. Lattice-based constructions are currently important candidates for post-quantum cryptography. Unlike more widely used and known public-key schemes such as the RSA, Diffie-Hellman or elliptic-curve cryptosystems—which could, theoretically, be defeated using Shor's algorithm on a quantum computer—some lattice-ba…

The Lenstra–Lenstra–Lovász (LLL) algorithm is an algorithm that efficiently transforms a “bad” basis for a lattice L into a “pretty good” basis for the same lattice. This transformation of a bad basis into a better basis is known as lattice reduction, and it has useful applications.

Webused lattice reduction algorithm is also its simplest one: LLL [LLL82]. However, the quality of LLL is not su cient for all applications, especially in crypt-analysis. This has led to the development of stronger blockwise reduction algo-rithms [Sch87,SE91,SH95,GHGKN06,GN08a,MW16,ALNS20,ABF+20,ABLR21],

In 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.
