Web(Ring-)LWE oracle generators¶. The Learning with Errors problem (LWE) is solving linear systems of equations where the right hand side has been disturbed ‘slightly’ where … WebThe learning with errors (LWE) problem and its efficient ring variant (the ring-LWE problem) are related to well known worst-case problems over lattices, and hence are considered to be secure in the post-quantum world. In this paper we describe an efficient software implementation of an encryption scheme based on the ring-LWE problem [2].
WebApr 15, 2024 · The adaptive security requires that the adversary cannot break security of the scheme even if it can make queries to a constrain oracle and an evaluation oracle in an arbitrary order, where the constrain oracle returns a constrained key punctured on the submitted set, and the evaluation oracle evaluates the PRF on the submitted input.
