For commutative rings, we introduce the notion of auniversal grading, which can be viewed as the “largest possible grading”. While not every commutative ring (or order) has a universal grading, we prove that everyreduced orderhas a universal grading, and this grading is by afinitegroup. Examples of graded orders are provided by group rings of finite abelian groups over rings of integers in number fields. We also generalize known properties of nilpotents, idempotents, and roots of unity in such group rings to the case of graded orders; this has applications to cryptography. Lattices play an important role in this paper; a novel aspect is that our proofs use that the additive group of any reduced order can in a natural way be equipped with a lattice structure.
