The Hardness of LWE and Ring-LWE: A Survey - IACR

WebThe original LWE problem is de ned over lattices and is not very e cient due to the use of large matrices. A more computationally e cient variant of the problem, known as the ring-LWE problem was introduced by Lyubashevsky, Peikert and Regev in [21]. The ring-LWE problem is de ned over a polynomial ring R q = Z WebA specialized form of Learning with errors operates within the ring of polynomialsover a finite field. This specialized form is called ring learning with errorsor RLWE. There are a variety of cryptographic algorithms which work using the RLWE paradigm. flip flop ring jewelry
