WebThe “learning with errors” (LWE) problem is to distinguish random linear equations, which have been perturbed by a small amount of noise, from truly uniform ones, by introducing an algebraic variant of LWE called ring-LWE, and proving that it too enjoys very strong hardness guarantees. 1,858 PDF 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].

In particular, the latter fixed quotient ring schemes are defined over one specific polynomial quotient ring, such as Z_q[x]/(x^n+1). In a sense those schemes place all their `security eggs in one basket', as they rely on the hardness of PLWE or MLWE
