WebTools. In discrete mathematics, ideal lattices are a special class of lattices and a generalization of cyclic lattices. [1] Ideal lattices naturally occur in many parts of number theory, but also in other areas. In particular, they have a significant place in cryptography. Micciancio defined a generalization of cyclic lattices as ideal lattices. http://short.iacr.org/news/index.php?next=20382
