Integer Version of Ring-LWE and its Applications

Gu Chunsheng

Abstract

In this work, we describe an integer version of ring-LWE over the polynomial rings and prove that its hardness is equivalent to one of the polynomial ring-LWE. Moreover, we also present a public key cryptosystem using this variant of the polynomial ring-LWE.
